With hundreds of thousands daily services worldwide Altronic ignition systems, modular wiring systems EZRail ®, ignition coils, spark plugs and secondary cables are recognized by the operators of industrial engines as the more sophisticated products in the world for purpose.

This did not happen by accident, it all started with a commitment to the customer over 50years combined with product development, design and engineering expertise that generates a unique addition to using the best materials available.

To this is added the manufacturing process certification ISO 9001, this formula results in products that offer the kind of extended service and free of problems that oil and gas industries both require and expect.

Products that reduce operating costs and minimize production downtime while reducing and simplifying trouble-free operation. This attention to detail is evident in each component and ignition system, as in the products EZRail ® and FLASHGUARD ®, secondary cables and plugs which are designed and constructed to ensure that each system sent the ignition energy required for combustion consistently effective.

Volver Arrriba




Modular Ignition Rail System for Natural Gas Engines EZRail  ® is a comprehensive line of modular ignition wiring and coil-mounting systems. Factory-built in Altronic’s Ohio facility, EZRail ® systems are thoroughly tested to ensure maximum reliability and performance.

Operational and functional benefits include: 

  • Complete wiring/mounting system from the ignition unit to

the ignition coils. Eliminates hours of wire and conduit cutting

in the field. Guarantees against skinned insulation due

to long conduit pulls.


  • Universal design takes advantage of standard cables, wiring

rails and integral/flange or off-mounted coils (shielded or

unshielded). EZRail ® systems can be cost-effectively configured

for service in any hazardous or non-hazardous area.

Optional bolt-on coil mounting rails give users a robust and

reliable means of mounting ignition coils without compromising

the integrity of the wiring rail or the ability of the rail to

be serviced if necessary.


  •  Flexible and upgradable. If coil types are changed, e.g.,

from unshielded to shielded or integral, the same wiring rail

can be used without modification. The same is true if the

coil mounting rail is added later. Competing systems require

a completely new, entirely different rail assembly.


  •  Premium construction materials. No “pop rivets” or foam

here — only high-quality aluminum extrusions, sealed

junction boxes, and military-style connectors and harnesses

are used. To insure long-term service, all connector back

shells are potted and strain-relieved.


  • Fully serviceable. An ignition wiring rail is too critical to be

a “disposable” item. Incorporating standard Altronic ignition

components into the design, including the primary and

secondary cables and leads, allows for quick, cost-effective

repair and service in the field. In the unlikely event that the

rail itself requires service (or if on-engine mechanical work

is required), the EZRail ® system can be easily disconnected,

removed, and re-installed.



  •  Service makes the difference. EZRail® is backed by the

most capable and experienced gas engine accessory product

distribution system in the world. At the end of the day, good

product performance relies upon solid field service. Altronic

Distributors and Dealers are unparalleled in their ability to

deliver timely, high-quality technical services for all products,

including the EZRail system.



Spark Plug Leads


Altronic offers a complete line of ignition spark plug leads for use on standard applications as well as for applications operating in

areas requiring Class I, Division 2, Group D compliance. These high quality industrial leads are available with a wide variety of

primary and secondary terminations for use with unshielded and shielded coils as well as standard and shielded spark plugs.

FLASHGUARD ® secondary lead assemblies, which incorporate an integral 5,000 ohm resistor and tight-fitting silicone or Teflon

boots, provide longer spark plug life and excellent durability.

Engine-related digital controls and instrumentation also benefit from the reduction in RFI (electrical “noise”) brought about by

the built-in resistor. FLASHGUARD ® spark plug leads are also available with special extensions for deep well applications.


 . High quality, corrosion-resistant components for heavy duty

industrial applications


. Wide variety of ignition coil and spark plug termination options


. Shielded and unshielded configurations available


. Boot and lead assemblies, featuring integral 5,000 ohm resistor

and high quality boot construction, improve flashover

resistance, plug performance, and reduce RFI


FLASHGUARD® Industrial Spark Plugs


FLASHGUARD ® industrial spark plugsare designed to increase effective spark plug service life by reducing flashover and electrode erosion while optimizing combustion and minimizing radio frequency interference (RFI).

Modern spark-ignited gas engines, particularly high performance, lean-burn configurations, demand that increasingly higher voltage levels be delivered to the spark plug to insure a strong spark at the plug electrodes. The FLASHGUARD® family of products meets the industry need for high-quality secondary leads and spark plugs to complement Altronic’s high performance digital ignition systems, such

as the CD200, CD200D, DISN, CPU-95, and CPU-2000.

The ignition system is only as good as its weakest link—the delivery of the high voltage spark energy between the ignition coil and spark plug electrodes. FLASHGUARD® products provide an effective solution, even in demanding applications, and offer engine users reduced operating and fuel costs, as well as less frequent spark plug changes. Whether in search of longer spark plug life in conventional engines, or reliable combustion in lean-burn applications, the features and capabilities of the FLASHGUARD®  secondary leads and spark plugs make them a logical choice for use on any industrial engine application.




The ignition coil is a final and most critical component in the ignition system performance chain. Available in several electrical and physical configurations, Altronic coils are produced in a new, stateof- the-art facility — the most advanced in the world dedicated solely to industrial engine ignition coils. The plant incorporates advanced, customized equipment and manufacturing processes to assure consistent, high quality production of high voltage coils — a component very sensitive to process variations. For optimum performance and reliability, the ignition coil must be properly matched to the ignition system output characteristics. Despite look-alike appearance, other sources of coils simply are not the same internally, and don’t offer comparable output and quality. A variety of coils are offered to meet application requirements.

Unshielded Round Case Coils The standard for unshielded coils, the well-known Altronic blue, red and

black variations are used in applications not requiring hazardous area certifications.

Unshielded Square Case Coils An alternative to the round case design, these coils have extended spark




 FLASHGUARD ®, Shielded, and Safe-T-Lead™ Spark Plug Leads



Altronic offers a complete line of universal and custom Flashguard ® spark plug eads. These premium secondary leads are designed with a 5,000-ohm integral resistor and with tight-fitting silicone or Teflon ® boots for reduced emitted RFI, minimized flashover, and improved spark plug life. For those operating in Division 2 hazardous areas, Altronic offers two certified

secondary lead styles designed for use with shielded spark plugs. The traditional braided stainless-steel lead is certified as safe for use in Class I, Division 2, Group D hazardous areas. As an alternative, the Altronic Safe-T-Lead™ is a non-metallic lead designed for use in conjunction with shielded ignition coils and spark plugs, but eliminates the corrosion and spark plug life issues associated with traditional metallic leads. The non-metallic nature of the Safe-T-Lead™ lead also enables the user to employ traditional diagnostic tools such as an ignition timing light in troubleshooting the ignition system and the engine.

See the Altronic Industrial Spark Plug and Ignition Accessories catalog for further details.




24VDC Alternator Power Packages


The alternator power packages are designed to deliver up to 70 watts of DC power to users wishing to operate the latest DC-powered ignition systems, instrumentation, and control products, on installations lacking access to electrical service. To promote easy field retrofit, the alternator units are designed to mate directly to various flange-mount magneto drive configurations. A belt-driven version is also available.

Two variations of the power package system are offered:

  • Version I — Consists of an alternator,


voltage regulator, battery pack and


cable. This system can furnish up


to 4 amps at 24Vdc for powering


ignition, instrumentation and




  •  Version II — Consists of an alternator,


voltage regulator and cable optimized


to make a self-powered ignition


system for the Altronic CPU-90 or


DISN. No battery is used with the


Version II system.


Go to Top

Altronic has a long and successful career in design and manufacturing of products dedicated to motor control and industrial control systems, air / fuel ratio control, fuel / governance among others.

These multifunctional systems have offered to customers operating gas engines reliable service since its introduction in the early 80's The introduction of EPC ALTRONIC-100 marked the beginning of the widespread use of microprocessor-based controls, to measure the air / fuel stoichiometric engine with carburetor.

Each engine manufacturer has its own unique set of performance requirements and start. For over 20 years ALTRONIC has achieved these individual needs with high quality products that are installed facially understood and engines installed in large and small. Constant attention to product development and quality manufacturing have made users worldwide use brand management products to meet their needs ALTRONIC control air / fuel, speed control and start.

EPC-50 Air/fuel ratio 

The Altronic EPC-50 is an air/fuel ratio controller designed for use on low-horsepower, carbureted natural gas-fueled
engines. It employs microprocessor technology, allowing for a high level of sophistication in control strategy, ease of configuration
and diagnostic capability. The EPC-50 and associated small engine-specific control valves are designed for use on engines operating
at or near a stoichiometric air/fuel ratio and is ideally suited for application with 3-way catalytic converters. While it is designed to be mounted in the engine/
compressor control panel, a NEMA 3R housing (720004-1) is also available as an alternative mounting option.
The single control output of the EPC-50 allows for its use on any engine application incorporating a single fuel gas regulator. An oxygen sensor is used in the
exhaust stream to sense O2 content, and a thermocouple input signals when proper exhaust temperature has been reached to allow for accurate sensor operation.
A system fuel control valve installed in the fuel line to the carburetor is precisely adjusted by a stepper-motor under microprocessor control to maintain the
correct O2 content in the exhaust. The desired air/fuel ratio can be easily adjusted by changing the control target voltages
through the sealed membrane keypad or through the use of a PC. The EPC-50 also incorporates a thermocouple input and a dedicated output for implementation of
catalyst over-temperature protection. A second digital output is available for use as an alarm for diagnostics

EPC 110/120


EPC-110/120 Air/Fuel Ratio Control and Monitoring Systems for Carbureted, Stoichiometric Engines The Altronic EPC-110 and the EPC-120
are air/fuel ratio controllers for use on carbureted gas engines. These controllers utilize microprocessor technology, allowing a high level of sophistication
in control strategy, ease of programming and diagnostic capability. The EPC-110 is intended for stand-alone, off-engine, post- or wall-mounting. The EPC-120 is
intended for off-engine, panel mounting.

Both controllers are identical in operation. The EPC-110/120 is designed foruse on engines operating at or near a stoichiometric air/fuel ratio (lambda .95 –
1.05) and is ideally suited for application with 3-way catalytic converters.
The control approach of the EPC- 110/120 assures engine operation at the optimum lambda (exhaust
oxygen) setpoint determined to be the point of maximum catalytic
converter efficiency and minimum engine emissions. Once determined (through an analysis of the engine exhaust),
it is entered into the EPC-110/120 as the control setpoint. Using a sensor in the exhaust
stream to sense the O2 content, the unit begins to adjust the flow of fuel to meet
the proper exhaust oxygen setpoint(s) for minimum emissions. The full-authority
fuel control valve(s), mounted in the fuel line between the carburetor and the final
cut regulator, assures precise, repeatable control of the air/fuel ratio without resorting
to the potentially dangerous strategy of adding fuel to the air intake of the

Monitoring and protecting the engine and catalyst from high temperature-related damage or out-of-compliance operation is a key function of the EPC-110/120 system.
Critical temperatures are monitored against user-adjustable setpoints using type K thermocouples.


EPC 100E


EPC-100E Advanced Air/Fuel Ratio Control System for Carbureted, Stoichiometric Engines The most full-featured of the EPC series,
this highly-capable system is unique in its capacity for customization and precision
control of the air/fuel ratio, particularly on engines with highly dynamic ambient and/
or operational conditions. The EPC-100E combines a proven control approach with
the ability to tailor both the lambda setpoint and responsiveness to any excursions
in the monitored air/fuel ratio. 
An effective, closed-loop control approach and simplicity of installation and setup
have made it the control of choice worldwide.
Recently, however, many users have found it necessary or helpful to apply new
air/fuel ratio control capabilities as part of a larger effort to secure more consistent
Air/Fuel Ratio Control Systems and Accessories or even further reduced exhaust emission
levels across a range of operating conditions.

The EPC-100E offers advanced, usercustomizable control parameters for the dynamic adjustment of the target O2 setpoints and
controller gains, as well as a means of inhibiting automatic control on the basis of satisfying an external parameter such as
load or a post-catalyst O2 setpoint. This is accomplished through the use of a proprietary,
high-level Windows™-based software package. For example, an EPC-100E
can be dynamically adjusted versus load (typically derived via an input transducer
monitoring air manifold pressure).


 EPC 150


The EPC-150 is designed for use on all lean-burn, carbureted, natural gas-fueled engines. Suitable applications include Caterpillar

3400 and 3500-series, Waukesha VHP-class, and most Cummins and Superior models. This innovative control offers reliable, precise, and positive air/fuel ratio control, with simple installation and operation. It also incorporates advanced operating features which address engine conditions specific to lean-burn operation.

The EPC-150 adjusts fuel delivery to meet and maintain a user-entered exhaust oxygen setpoint. The exhaust oxygen level is continuously monitored by a lean-burn oxygen sensor. During system setup, an exhaust gas analyzer determines the oxygen level at which engine-out emissions are at their lowest, and the corresponding setpoint is entered into the EPC-150 as the control setpoint. As load and other parameters change, the EPC- 150 maintains the air/fuel ratio necessary to meet the desired exhaust

oxygen level, assuring “in-compliance” engine performance.

A unique control protocol limits “lug” conditions, whereby a lightly loaded lean-burn engine becomes incapable of generating sufficient turbo boost to meet

the speed setpoint established by the governor. This control approach — which monitors intake air pressure both before and after the throttle plate — enables the controller to automatically offset the oxygen setpoint for richer operation and

ultimately increased turbo boost pressures.

With the engine operating more smoothly and achieving the necessary RPM, automatic control at the desired oxygen setpoint is then restored. As with all other EPC-150 operating parameters, the point at which such an offset would be made, and its value, is fully adjustable from the keypad of the control unit or remotely using the integral RS-485 ModBus RTU communications system



EPC 200C


Complete air/fuel ratio and ignition timing  control for fuel-admitted gas engines is provided by the Altronic EPC-200 Engine
Performance Controller.

Replacing obsolete OEMand/or pneumatic controls,this flexible andfully-configurable system is an effective upgrade solution for operators of turbocharged integral compressor engines, as well as high-speed, fuel-admitted separable engines including many Superior and MEP models. Monitored engine RPM plus up to four other analog inputs are used as control variables. In a typical application, fuel manifold pressure, air manifold pressure, and air manifold temperature are configured as the primary control inputs. The fourth (unspecified) input is often connected to a variety of devices including exhaust oxygen sensors, KW sensors, and

calorimeters. Using operating data taken from the existing controls and determined during the commissioning process, these monitored values are used as inputs to optimize both the engine air/fuel ratio and the desired ignition timing across the range of ambient
conditions, speeds, and engine loads. Control of these functions

is accomplished by two independent 4-20mA signals: one for use with an Altronic CPU-series digital ignition system (timing control), the other to an I/Pbased turbocharger by-pass for wastegate control (air/fuel). Six user-programmable solid-state relay outputs are also available to incorporate common sequencing functions such as purge, overcrank, crank disconnect, etc.




Designed for service as an actuation device for a supervisory speed governing or air/fuel ratio control system, the Altronic AGV5 is a single-stage, electronicallyactuated, balanced poppet, fuel control valve. Due to its precision control, rugged

design, and tolerance to fuel contaminants and corrosives, the AGV5 is used extensively on integral compressor applications and

on other large fuel-admitted natural gas engines (such as Superior and MEP) as an upgrade over existing pneumatic fuel actuators.



Control is derived from industry-standard 4-20mA output signals generated by the associated controller. For speed control applications, this would require that all governing logic, RPM and pressure setpoints, and timers be defined and resident within the controller itself, driving the AGV for fuel actuation.

(Note: If a full-authority, turnkey speed control capability is required, please see the description of the GOV10/50 Gas Engine Governing Systems on page 10). Two models of the AGV5 are available (standard and high-flow) to accommodate the fuel flow control needs of engines up to 10,000 horsepower.



GOV 10/50


GOV10/50 Gas Engine Governors Taking an innovative, unique approach to  fuel-admitted gas engine speed control,  the Altronic GOV10/50 Systems bring  both the fuel control valve and a sophisticated electronic governor together into a single, integrated unit.


Designed for use on both integral compressors such as Cooper- Bessemer, Clark, Ingersoll-Rand, and Worthington, as well as high-speed separables such as Superior and MEP, these robust, precision-control devices effectively eliminate troublesome hydraulic governors, actuators, and linkages. The result is significantly improved starting performance and speed stability across the engine load range.  the GOV systems are mounted directly in the engine fuel line, and very precisely control gas flow to the engine by changing the position of an internal poppet valve.

Using fuel gas pressure as the “muscle” for the actuation force, this poppet valve is moved in the open or closed direction to meter the delivery of the fuel and to regulate and govern the speed of the engine under all loads. On-board pressure, differential pressure, and temperature monitoring sensors, along with engine RPM and an optional fuel flow measurement capability allow for accurate

control of engine speed. A sophisticated, user-tunable speed governing algorithimis resident within the GOV enabling the system to properly meet the individual  startup, loading, and run requirements of each engine. Since many engines are highly sensitive to flooding at startup, the GOV10 can easily be configured to control to a specified pressure curve during the start and warm-up cycles, and then to switch to an RPM setpoint-based control strategy for run conditions.

Two GOV models are available—the GOV10 is used on engines up to approximately 3,500 hp, and the GOV50 applies to engines ranging from 3,500 to 10,000 hp. Configuration of the GOV can be accomplished through the system Display Module or via the ModBus-RTU-based GOV10 Terminal Software included with each unit. That same RS-485 serial link can also be used for direct interaction between the GOV and a supervisory device for remote system monitoring and control.




SaveAir™ Electronic Air Start System Built to replace troublesome, maintenance- intensive OEM or pneumatic air start distribution systems, the Exline-Altronic SaveAir™ Electronic Air Start System brings solid-state electronic control to the starting function of air-inhead starter equipped, integral compressor engines. Eliminating the mechanical air-start related components, the state-ofthe-art SaveAir™ system introduces significant operational advantages, including a substantial reduction in the required starting air (up to 70%) and the elimination of starting “dead spots”.

The heart of the SaveAir™ system is an innovative, engine-mounted position sensing device used to determine the precise

angular location of the crankshaft, even while the engine is at rest. With accurate radial position data in hand, the SaveAir™ system electronically actuates air-starting solenoid valves, which precisely control both the turn-on time of the air-in-head valves as well as the duration of the individual air admission events during sartup. These unique capabilities enable the SaveAir™ system to deliver starting air to those cylinders which are most appropriate given the angular position of the crankshaft —

virtually eliminating engine starting “dead spots” — and to drastically reduce the amount of starting air required. More reliable

remote starting, improved operator safety (no mechanical barring), reduced air consumption, and more efficient compressor

station operation are just a few of the benefits of SaveAir™ operation.

All SaveAir™ system electronics are “universal” in their design and common to all applications. Engine-specific Logic/Distribution Module flanges and/or adaptors ensure a simple installation on virtually any suitable engine. Configuration and

monitoring of the SaveAir™ system can be accomplished through the Display Module or via the PC-based Terminal Program supplied with every unit.





Actuating Control Valves (690-Series) To operate in conjunction with its Air/ Fuel Ratio Control Systems and other gas control applications, Altronic offers a complete family of actuating control valves. These rugged and reliable actuators incorporate sophisticated position control technology (digital linear actuator-based), and have become the fuel control standard in the oil, gas,

and power generation industries for the precision control that they offer And the minimal maintenance and calibration that they require. Altronic actuating control valves are available in both the piston style (silver body), and butterfly plate (black body) configurations.

“Universal” in their design, they are suitable for use with all Altronic controllers on both in-line and V-typeengines, and on both naturally-aspirated and turbocharged models. 1.5" NPT, 2.0" NPT., 2.5" NPT, and 3.0" NPT fuel line diameters can be directly accommodated without the need for additional adaptor fittings in the line.


Stepper Motor (Fuel Control Valve) Controller (SMC-Series)


The SMC-series Stepper Motor Controller is designed to give users of control systems having a standard analog output

an effective and convenient means of integrating Altronic Actuating Control Valves.

The unit is DIN-rail mounted and easily installed in the back of a control panel or

other suitable enclosure.

A standard 4-20mA input control signal is used as the primary input to the SMC Controller. That input signal is converted such that, across the 4-20mA range of the input, the user achieves a fully linear 1700-step span to dynamically adjust The position of the control valve piston or butterfly. The SMC board drives a single actuating Control Valve.




 The EPC-250 is a sophisticated, purpose-built control system designed specifically for use on large, integral compressor engines (Cooper®, Clark®, Worthington®, many Ingersoll-Rand® applications) and fuel-admitted, high-speed separable engines Designed as a direct successor to the successful and long-serving EPC-200 systems, the EPC- 250 is constructed to be installed in the same panel cutout/footprint and to provide full backward compatibility with existing EPC-200 installations in providing automated and optimized control of the engine’s ignition timing and air/fuel ratio. This intelligent device, however, brings with it significant additional capability and functionality beyond traditional EPC-200 systems:

An 8.4” LCD touchscreen to support all system configuration and interface requirements as well as a graphical, live display of key operating and control parameters.


Sophisticated system trending and datalogging of critical operating values for enhanced performance analysis and troubleshooting


On-board web server for remote access/control


Integrated diagnostics for out-of-bounds operation and fault conditions


RS-485/232 and 10/100 Ethernet communications for integration into existing control systems and remote system access


User interface support of multiple languages


All system components CSA hazardous area certified for use in Class I, Division 2, Group C and D areas


While the EPC-250 represents an ideal, cost-effective (see below), and intuitive retrofit candidate for existing EPC-200 installations, it can also be incorporated into a new Altronic Controls DD, DE, or Exacta-based safety shutdown and monitoring control panel. This flexibility in integration allows for customer operational needs for these special applications to be precisely met across the range of budgetary expectations and technical support capacity/sophistication.

During the last forty years has been ALTRONIC defining and redefining the concept of high technology when it comes to ignition systems and accessories for industrial natural gas engines in 1966 introduced the system of solid state ignition systems, ignition discharge capacitors for industrial ignition  in order to solve the need to extend a trouble-free operation.

The engineering approach was unique ALTRONIC: An alternator allows multi-pole magnet (for motor power), solid state electronics (replacing mechanical components) as well as design and modular construction (for ease of maintenance). A corporate commitment to excellence in engineering and customer service helped make ALTRONIC ignition systems standard equipment on most OEM original equipment manufacturers worldwide.

Application experience and a global network of distributors ensures successful use of the ALTRONIC  line of products in any industrial engine ignition requirement.

Ignition systems by ALTRONIC are divided into 3 categories namely:

• solid state systems (mechanical systems)

• digital ignition systems referenced to disk

• digital ignition systems referenced to the crankshaft this  systems consist of a solid ALTRONIC self powered unit, a cable assembly and the appropriate number of ignition coils. Operating power is provided by a self-contained generator, multi magnetic pole which loads an energy storage capacitor.

Coils magnetically referenced provide timing pulses to discharge the capacitors in a given sequence. These discharges low voltage are routed by a distribution system consisting of a rotary magnet component and solid state switching to the ignition coil of the appropriate cylinder. Electrical components are mounted easily integrated with replaceable modules.

All features integrated ignition systems allow solid state contribute a long mechanical cycle life.Solid state systems include:





Volver Arrriba

First introduced in 1966,brought the advantages of capacitor discharge ignition to industrial gas engines.
It consists of a small permanent magnet alternator with a plug-in electronic module attached. Timing is set by one or
more remote mounted pick-up sensing magnets referenced to the engine crankshaft.
On horizontal engines, these are typically mounted on the flywheel; on in-line engines, a magnet disc is used. The alternator performs no timing
function and can thus be either belt- or coupling-driven. The only moving part is the alternator’s sealed, underloaded ball
Over 60,000 Altronic I systems have been sold. The system’s simplicity and long record of field reliability have made
it the ignition of choice for operators of low-horsepower industrial engines.
Altronic II 

provides a self-powered, capacitor discharge system for large-bore, slow-speed gas engines. With four different internal gear ratios, base or flange mounting, and three drive coupling choices, Altronic II can be readily specified to replace most older magneto or breaker-point ignition systems. Altronic II can be used on engines with either one or two spark plugs per cylinder.

With an operating base of thousands of units, Altronic II has a proven record for reliability. Users can also easily upgrade
to the Altronic II-CPU system while retaining the Altronic II alternator section to supply system power requirements.


for Medium-Sized Engines, 2-16 cylinders

With over 40,000 units in the field, Altronic III has become the industry standard system for medium-sized stationary gas engines. Altronic III is offered with seven mounting variations and six internal gear ratios to fit virtually any application in its class. Three types of electronic timing control are also offered: dual timing settings, timing vs. RPM and

timing vs. 4-20 milliamp signal. Ease of service is assured by the replaceable back cover, which contains all the

system electronics. Other options include a choice of standard or long spark duration coils in both unshielded and shielded versions. Altronic III can also be upgraded to the benefits of crankshaft-referenced, electronicallycontrolled timing — refer to the Altronic
III-CPU system.


for Small In-Line Engines, 1-6 cylinder

Altronic V offers the same design features, installation ease, dependability and serviceability that are built into
Altronic III, but in a smaller package. Six mounting variations and a dual-position electronic timing option are additional features.
Altronic V affords small engine users a cost-effective replacement for obsolete and maintenance-intensive breaker-point
magneto systems.

Family for Small Engines to 8-cylinders 
The Altronic CD1 Digital Ignition System has been developed for application on small, stationary industrial engines up
to 8 cylinders. This moderately-priced, easily installed system utilizes a lowcost magnetic pickup sensing drilled
holes (usually in the engine flywheel) to determine the angular position of the crankshaft. LED indicators give diagnostic
signals regarding input power, the pickup signal, and correct ignition unit operation. Individual coils or economical
multi-cylinder coil modules can be used in conjunction with the CD1 system.

The Altronic CD200D is suitable for both unshielded and shielded systems on engines up to 16-cylinders. Housed in the
traditional DISN enclosure, this advanced digital ignition system incorporates all of the same capabilities and functionality
resident in the standard CD200 product, including adjustable output energy, primary and secondary discharge diagnostics,
automatic timing adjustment curves, and ModBus RTU communications.

DISN -800C


 DISN 800C for Medium-Sized Industrial Engines

The DISN is a full-featured industrial ignition system for small- to medium-sized stationary engines up to 16 cylinders. The
DISN system is intended for compressionstroke firing and usually uses a single pickup sensing, precisionmachined
timing disc rotating at engine camshaft speed.
If crankshaft-referenced timing is desired, two pickups are used: one sensing firing magnets placed in the engine flywheel and
the second sensing a single index magnet rotating at camshaft speed. DISN offers up to eight firing patterns in a common
unit and is available in 8, 12 or 16-output models, each with multiple applications.
The DISN systems also incorporate four advanced timing control options: manual 16-position timing switch, one-step timing
change, remote potentiometer timing control or control from a 4-20 milliamp analog signal. Three LED diagnostic indicators
give an instant indication of the basic incoming power and pickup signals. The cast housing offers superior protection in
harsh environments.


CPU- 95 / CPU95C


Altronic CPU-95 for Medium Stationary Engines The Altronic CPU-95 is a DC-powered, capacitive discharge digital ignition
system for medium-sized industrial gas engines to 20 cylinders. The Display Module, typically mounted in the engine
control panel, gives the user convenient access to critical operating information such as ignition system mode, engine
speed, system diagnostics and setup functions, and the value of the 4–20mA signal being used for automatic timing
control and the timing of the ignition system.


  • CPU-95C
Developed for use on SI Controller-equipped Caterpillar 3500-series engines, the CPU-95C system replaces both the existing
Altronic III unit and AIB box. Its installation allows for full access to the critical operational and diagnostic information and enhanced spark
characteristic control resident in standard CPU-95 systems.



  • CPU-95 VariSpark™
An innovative variant which uses capacitivedischarge ignition technology to deliver a long-duration spark, typical
of an inductive ignition system. This model is of particular interest to operators of large bore, low-BMEP

CPU -2000


for Large Stationary Engines

The DC-powered CPU-2000 system is designed for application on all large-bore stationary gas engines and can accommodate
virtually any engine firing pattern. A single, universal CPU-2000 Logic Module can be used in conjunction with either a
16 or a 32-output Ignition Output Module thus minimizing the number and variety of ignition components. A simple terminal
program allows one unit to fit all applications, and a field-replaceable memory minimizes overall engine downtime in the
event that the ignition system requires replacement.




The Altronic DE-1500 Universal Process Loop Controller is designed to control virtually any engine, compressor, or industrial process. Using both digital
and analog inputs for parameters such as speed, temperature, and pressure, this configurable control can use one or both of its independent PID outputs to dynamically
adjust a process(es) to maintain a specified setpoint. 
Among the many applications for the DE-1500 is as a suction controller for compressors in gas production or processing service. Continuously monitoring the
compressor suction pressure, the DE- 1500 can be configured to throttle the gas pressure control valve either directly
or via an interposing I/P converter. Similarly, critical temperatures could also be monitored and maintained via an input
thermocouple or temperature transducer, with one of the DE-1500 PID outputs controlling a compressor fin-fan or other cooling device. The DE-1500 can also
send a speed setpoint to a suitable governor or control device (such as the Altronic GOV10) for RPM controlof the compressor prime
mover (engine or electric motor).

DD-NT Digital Annunciators


Patented DD-NT annunciator systems, available in 20- and 40- point models, continuously monitor and protect
gas compressors, generators, pumps, and other types of critical equipment.
These solid-state systems scan the connected electrical contacts which may represent limits on functions such
as pressure, temperature, level, etc. The first-out cause of fault is displayed and remembered to aid in
troubleshooting and to minimize downtime.
Designed to replace mechanical indicators, relays, and pneumatic flags, the CSA-certified DD-NT systems indicate
operating mode and specific cause of fault. They can monitor for out-of-bounds conditions prior to startup, and have a
built-in class B bypass timer and onboard sensor test capability.






DD-40NTV Series Digital Annunciator

The latest version of the industry-standard annunciator, the DD-40NTV series monitors up to 40 electrical contacts that
represent limits on critical operating parameters such as engine or process pressures, temperatures,
levels, etc. Upon detection of a fault from one of the monitored points, the annunciator displays the corresponding 2-digit fault code for that point and generates
an output signal (typically to close a fuel valve and ground the ignition).
The DD-40NTV annunciator offers integral tachometer and hourmeter functions as well as overspeed protection adjustable
from the front keypad. Other features carried over from the prior DD-NTS series include four configuration templates (two
of these simulate the older DD-NT 20 and 40 point models), two programmed timers for class B points and a programmable
delay of the second shutdown output after fault detection. The annunciator continues logic operation on the internal battery
in the event the power becomes disconnected or fails.



The Altronic DE-1500 Universal Process Loop Controller is designed to control virtually any engine, compressor, or industrial process. Using both digital
and analog inputs for parameters such as speed, temperature, and pressure, this configurable control can use one or both of its independent PID outputs to dynamically

Series DE 


DE Series Safety Shutdown, Monitoring, Compressor Control and Communications System These innovative, CSA-certified systems
introduce a level of capability and functionality well-beyond standard, two-digit safety-shutdown annunciator devices. DE-
3000, the latest version of the series, can provide up to 62 inputs and 24 outputs.
Designed with state-of-the-art microcontroller technology, the DE Series is engineered and manufactured to protect,
monitor, and control critical rotating machinery such as engine or motor-driven
compressors, pumps, and generators. 
All DE devices directly accept both digital and analog inputs and continuously monitor those inputs for out-of-bounds operation or fault indication. Depending
on configuration, when an upset condition is detected, the DE system can shut down the machine using a discrete output or by shorting the ignition system and/or tripping
a fuel shutoff valve on a natural gasfueled engine. DE-3000 and DE-2500 also incorporate a sophisticated closedloop compressor capacity control capability
as well as automatic start functionality.
DE systems are suitable for retrofit applications or as the core product in a new control panel. System Power and Terminal Input Modules are typically DIN-rail
mounted within the enclosure for maximum installation flexibility. The Display Module (common to all systems) provides access via the on-board sealed membrane
keypad. A large, 4X20 character display offers a digital indication of monitored values (such as process pressures and temperatures), and a unique process
screen showing a group of related values in a bar-graph format. Integral speed indication (with overspeed protection) and 11 individually adjustable service meters
are resident in each DE system to ensure the timely indication of associated unit maintenance requirements. 
Integral ModBus RTU and ASCII communications allow direct remote access to system operating conditions, unit speed, operating hours, and other parameters
via satellite, radio, cellular, or landline communications. Local setup and system monitoring requires an included proprietary Altronic DE Terminal Software
Package. Should it be required, DE systems can also be conveniently replaced in the field by simply removing the system memory module and installing it into a
second device – effectively eliminating the inconvenience and cost associated with system reprogramming. Up to 100 time and date-stamped system datalogs
are retained in the system memory to allow for effective application monitoring and troubleshooting.


DE- 3000

Expandable and scalable DE-3000 system is built-upon the field-proven DE-2500 for engine safety shutdown and control on both screw and
high-spec reciprocating compressor applications ?? Each DE-3000 input is individually configurable for:

— Sensor Type: Analog transducer
input, thermocouple input
(type J or K), digital (switch

— Sensor Class: A, B, or C logic

— Digital Input Sensor Run/Fault
Status: N/O or N/C
—For applications requiring additional
input or control functionality, two
Terminal Input Boards can be used in
the DE-3000 system



The Exacta21 is an “all-in-one” preprogrammed system, dedicated to monitoring, controlling, and optimizing
gas compressors and associated site equipment.
It is focused on comprehensive, high spec controland monitoring applications (often managed by PLCs or other high-end controls)
where its processing power and large number of inputs and outputs are required. The Exacta21 differs from most PLCs however, in that it accommodates
configuration revisions directly from the keypad or via a standard PC, and the application core (where the design continuity
is governed by a manufacturer and not an individual programmer) of the configuration programs are the same from unit to unit. The Exacta21 offers significant
enhancements over prior models, including surface-mount construction and conformal coating of electronic components, reduced
board size, DIN rail mounting, and a fully integrated power supply.


DTHO-1201/3201 Universal Speed Monitoring Instruments with Hourmeter and Overspeed


These digital tachometers are designed for universal use. They are high-quality, microprocessor-based devices that can be powered from either a C.D. ignition “shutdown lead” or a magnetic pickup, and are offered in two durable Lexan enclosures for use on natural gas engines and other critical rotating equipment. Both models include overspeed trip and hourmeter functions. DTHO-1201 features a weather resistant 4-1/2" round case which can be mounted in an industry-standard cutout. It replaces the DT/DTH/DTO/DTHO-1200-series tachometer instruments. DTHO-3201 is packaged in a 4.19" X
5.00" Lexan case. It replaces DTO-1010, DT/DTH/DTO-3200 and the PT/PTH/PTO/ PTHO-2100 series devices.

DH-100A Digital Hourmeter

This solid-state digital hourmeter operates directly from CD ignition systems, 8 to 440VAC or VDC, or intrinsically-safe magnetic pickups. The DH-100A is designed
to withstand vibration and to give extended service in hazardous and demanding environments, eliminating the problems associated with mechanical devices. Power
consumption is negligible (microamps) and the device can be applied to virtually any process. Switches on the back of the unit allow the hour count to be preset to
any number, or reset to zero. When the power is disconnected, the accumulated count is retained and the readout can be
obtained by depressing the button on the front of the unit.

DSG -1201/1401 


The DSG-series instruments are built upon a common, microprocessor-based
platform and share a common set of installation and operationonal features.
These high-level, DC-powered instruments feature a unique digital/analog display,
simple user configuration via a sealed membrane keypad, multiple setpoints,
Form C (N/O or N/C) output switches, are housed in a durable 4-1/2" round Lexan
enclosure, and have optional 4-20mA outputs.
  • DSG-1201 Digital Setpoint Gauge Speed is designed to provide an accurate indication of speed on engines or other
critical rotating equipment. The required input frequency signal can be derived from the #1 cylinder ignition coil of a CD
ignition system or a magnetic pickup. Four individual setpoints and output switches can be configured for use in automation projects (start/stop, crank
disconnect, fuel on/off, etc.) 
  • DSG-1401 Digital Setpoint Gauge Ignition Timing offers local and/or remote indication of engine ignition timing. The
device accepts a CD ignition input signal from the #1 cylinder ignition coil and a magnetic pickup input signal to precisely determine and display the timing of the ignition
system. Two timing setpoints/outputs can be configured, with outputs three and four used to provide rotation-confirm and
fire-confirm for engine automation projects.

45PHL Pressure Switch-Gauge

with Low/High Setpoints The Altronic 45PHL-series pressure switch-gauges are the standard for mechanical
pressure gauges with low/high switch contacts.
Incorporating the innovative “directdrive” pressure-sensing technology developed and used for precision pressure test instrumentation, the 45PHL utilizes a special, helically wound coil of Inconel to properly determine and display the monitored pressure. This approach eliminates the internal gears and linkages used in traditional bourdon-tube based gauges, as well as their associated inaccuracy and poor reliability. The 45PHL offers the user extended service life, high accuracy (±1%), and repeatable readings across the range of application and environmental conditions. Fifteen different pressure ranges are available and are listed below.
To insure simple retrofit in the field, the 45PHL is packaged in a 4-1/2" round weather-resistant case designed to fit into industry-standard panel cutouts. The switch setpoint arrangement features two colorcoded low/high setpoint adjustment knobs on the front of the gauge. The 316 stainless steel connection stem is user-adjustable in the field for bottom or back connection. For maximum corrosion resistance, the device features stainless steel components, including all rivets and screws.

DPS-1591 Digital Pressure Gauge with Dual Setpoints The advanced, highly accurate (±.25% of
span), DPS-1591 Digital Pressure Gauge s a single point pressure monitoring device, ideal for use in monitoring process pressures. To assure maximum application
flexibility, the device is designed to accept power from the same two lines used for the 4-20mA proportional current loop output. For applications not requiring the
current loop, the unit can be externally powered with DC-power. Utilizing either power source, unit operation (and setpoint protection) is backed up by a very long life
internal lithium 3.6-volt “C” size battery. Using this same internal battery, extended stand-alone service (4+years) can also be achieved without the application of outside
power. Packaged in a standard 4-1/2" round case, the accuracy and numerous configuration options make it suitable for use in monitoring virtually any critical
pressure. Eight pressure ranges are available and are listed in the chart below.
In addition to power, display, and output switch flexibility, the DPS1591 DP incorporates a number of features designed to enable its use in a wide range of applications
and environments, including integral pressure transducer (with connection stem field adjustable for side or bottom mount), built from high-quality stainless steel and
incorporating a media isolated sensor with no internal o-rings, silicone oil or welds. A sealed membrane keypad, and an ABS plastic case further make this gauge
suitable for the measurement of gases or liquids in corrosive environments.

Series  DPYH-1300U / DPYH-1301U /DPYH-1392U/DPYH-1379U


DPYH-1300U Series Universal Temperature Sensing Instruments (Pyrometers) These are solid-state instruments that
give a continuous temperature readout and have an alarm/ shutdown capability at a user-adjusted temperature
limit. These “universal” 1-, 2- and 9-point temperature monitors are housed in durable, 4-1/2" round Lexan cases, can
be configured for readout in degrees Farenheit or Celsius, use industry-standard type J or K thermocouples,
and can operate from either 12-48VDC or CD ignition input power. The output switches integral to each unit are
suitable for use with Altronic annunciators or other specified devices.
The single- and dual-point DPYH-1300U models can be used on applications ranging
from engine oil and water temperatures to catalytic converter and turbocharger inlet/
outlet protection. The 9-point model is designed to use channels 1 through 8 for
engine cylinder exhaust temperature readings with point 0 used for turbocharger or
catalytic converter monitoring.
DPYH-1301U monitors one point with a
high-limit setpoint; it has output switches
for both N.O. and N.C. operation

DPYH-1392U monitors two points with
an individual high-limit setpoint for each
channel; it has output switches for both
N.O. and N.C. operation

DPYH-1379U monitors nine points with
point 0 protected by the first high-limit
setpoint, and points 1–8 protected by the
second common high-limit setpoint.


DSG Digital/Bar-Graph Setpoint Gauge for Pressure, Temperature, Vibration and Other Variables These advanced gauges monitor, display and protect either one or two process variables.

The DSG-1611 is a universal onepoint model. The DSG-1682DUPS and
DSG-1692DUS are two-point versions.
DSG gauges can be connected to either type J or K thermocouples, 0–5 volts or 0–25mA (scalable) input signals. In the DSG-1692, this choice is independent
for each of the two monitored points. All three versions have a RS-485 serial port and ModBus communications
with 5 selectable baud rates. Power requirement is 12–36Vdc, 0.25A maximum. DSG gauges feature a sealed membrane
keypad and a high-resolution digital readout/ bar-graph display which indicates the
reading as a percent of transducer span or span between high/ low setpoints, with a
reference to direction and amplitude of a rapid change in reading.

The display also indicates the units and annunciates an alarm by number and type.

Two (one on the DSG-1682DUPS) solidstate, form C (N.O. and N.C.) output switches can each be assigned high and low setpoint values which are retained indefinitely. The precision nature of these switches allows these gauges to be used
as control devices. 

DSG-1611DUPS The single-point model has both 4–20mA proportional output and RS-485 serial communications.

It replaces all prior models of the DSG- 1301 and 1601 and can be programmed for both a low and high output for each of the two output switches.

DSG-1682DUPS This dual-channel gauge is a single-loop PID controller offering the following modes of operation:?? 4-20mA output loop vs. the channel 1 input OR channel 2 – channel 1

(differential) ?? Direct or inverse PID output based on the input of channel 1 or in a “mapping” mode that allows the channel 1 PID setpoint to be modified by the monitored input of channel 2.


DSG-1692DUS In the standard dualpoint model, each channel is independently assigned for type J or K thermocouple, 0–5 volts or 0–25mA input
signals. This allows the device to be usedfor one temperature and one pressure or two of either type. In addition, the device can be set up with a differential setpoint
between the two monitored points.

DPY  SERIES  DPY-4118U-A  / DPYH-4300U / DPYH-4354U/ DPYH-4394U / DPYH4396U / DPYH-4398U / DPYH-4320U

DPY-4118U-A Digital Pyrometer The intrinsically-safe, internally powered DPY 4118U-A digital pyrometer is a costeffective,
accurate, and reliable alternative to traditional mechanical switchbased temperature devices and analog meters/gauges. Offering 1° resolution and

DSM-43900DUS-Series Digital Setpoint Monitors for Temperature Designed specifically for monitoring temperatures on engines,
compressors, and other critical applications, these devices operate on12-30VDC power and use standard type J or K thermocouples as
inputs. All DSM-43900DUS units feature ModBus RTU communications via an integral
RS-485 output.
Each of the three “universal” devices has four individual setpoints (two high and two low) per channel and two output switches. These units may be used in
alarm/shutdown service or in any other configuration where the monitored points serve two functions. The monitoring capability
of the device is further extended through the incorporation of a unique grouping function whereby all temperature
input channels can be sorted into a single- or two-group configuration with individual group setpoints attached to each (two high, two low, and two differential).
All models feature a sealed membrane keypad and large, backlit alphanumeric display for indication of the channel
number, the value of the monitored temperature, and a bar-graph showing the position of the monitored temperature between the low and high setpoints. All
setup details, including thermocouple type (J or K), temperature units (F. or C.), calibration, and individual high/low setpoint values are accessible and adjustable
from the front of the device. Fault information by sequence of occurrence
is available on both the unit display and via the RS-485 serial port. ModBus RTU
allows for remote communications of the monitored conditions.
DSM devices are housed in a gasketed, powder-coated aluminum enclosure and
assembled using stainless steel hardware, making them ideal for use in oilfield or
other environmentally-challenging applications.

?? DSM-43924DUS accepts up to 24 type J or K thermocouple inputs


DSM-4600DUS Series 


These monitors provide cost-effective multipoint monitoring of pressures, temperatures, or other process variables on compressor packages and generator
applications in a serial communications environment. The ability to monitor and display up to eight analog transducer inputs, combined with an integral RS-485
communications capability makes the DSM-4600DUS an ideal “front end” data collection device for use with supervisory controllers such as the Altronic DE-Series
systems and remote monitoring (SCADA) systems.
All models are 12–30VDC powered, and feature a sealed membrane keypad as well as a large, backlit LCD display
for both the channel number and the value of the monitored variable.

All DSM devices are housed in gasketed, powder-coated aluminum enclosures and assembled using stainless steel hardware, making them ideal for oilfield or other
environmentally-challenging applications.

The ETM-40US Universal Temperature Monitor/Scanner is a microprocessorbased instrument that monitors up to 40 process temperatures. While primarily
designed for monitoring critical temperatures on reciprocating engines and compressors, the availability of 10-36VDC or 100-250VAC as input power options, the
suitability for use with either type J or K thermocouples, and the wide variety of input and output module options allows for the application of the ETM-40US to
virtually any industrial process requiring state-of-the-art temperature protection.
Each of the monitored points is arranged n one of seven temperature groups (see chart). This allows the user to group similar points (such as engine cylinder
exhaust temperatures or turbocharger outlet temperatures) which can be measured against a set of common alarm, shutdown, and differential setpoints. Low
and high setpoint monitoring for each channel is also available. The ability to choose between two sets of setpoints for
each channel and for each group, along with the flexibility in mapping of those setpoints to individual outputs, enables the ETM-40US to be used for both



DET-1600/1620 Detonation Sensing Monitors

The Altronic DET-1600/1620 Detonation Sensing Monitors are 24VDC-powered, 32-bit microprocessor-based electronic instruments designed for use on natural
gas-fueled engines to detect detonation and misfire and avoid consequential engine damage. Industry-standard, lowcost, piezoelectric vibration sensors are
mounted directly on the engine and are used to transform the vibrations caused by combustion into electrical signals which are then evaluated by the DET-
1600/1620. These values – generated for every cylinder on a cycle-by-cycle basis – are then measured against misfire and detonation setpoints configured by the
user for the monitored engine. The monitors accept up to 16 detonation sensors wired to pluggable Phoenix-type connectors; the recommended configuration is
one sensor per cylinder.

The DET system can be configured to take a number of control actions to protect the monitored engine upon indication of detonation (or misfire). In many applications,
the DET will utilize one of two solid-state output switches to activate an external unloader to reduce engine load.
Should that remedial action be unsuccessful addressing the detonation issue, the DET can be configured (when used in conjunction with a digital ignition system)
to automatically retard the ignition timing. In the event that an ignition timing adjustment also proves to be ineffective
in eliminating engine detonation, the second output switch – typically tied to a digital annunciator or other monitoring device – acts as a final safety measure to
shut down the engine.


VSM Vibration Sensing Monitor


The VSM is a 32-bit microprocessorbased electronic instrument designed to protect industrial engines, compressors, and associated equipment from damage
caused by excessive vibration. The monitor accepts up to four (VSM-400) or eight (VSM-800) industry-standard low-cost, broadband, piezoelectric vibration sensors
that are used to transform mechanical vibrations into electrical signals which are then evaluated by the VSM. The resulting vibration levels are displayed on a LCD
display and are compared to user adjustable setpoint levels (2 per channel). If a high vibration level surpasses a userconfigured setpoint value, an indication is
shown on the LCD and an output switch — one for alarm and one for shutdown — is activated. 
With each input channel operating independently of the other, the VSM can be used as the monitoring device for all of the vibration points of interest on
an application. For example, individual sensors mounted on a gas compressor cooler, on each bank of the engine, and on the compressor cross-heads are
individually configured for the appropriate vibration characteristics and monitored by a single VSM device. RS-485 Modbus RTU communications is resident in the
device allowing the vibration data from each channel to be communicated to a control PC/PLC or remotely as a means of determining the overhaul health and wellbeing
of the equipment. Configuration of the device can be accomplished simply and conveniently directly from the front of the device using the system keypad
or through the use of the VSM Terminal Program included with each unit.


GSV-Series Gas Shutoff Valve 
The GSV-series Gas Shutoff Valve automatically
interrupts the flow of fuel in the event that an
engine or process fault is detected

system such as the Altronic DD- or DE-series
The Altronic LLS represents the next
generation in liquid level
protection for gas compressor
scrubbing and dehydration
units as well as other
applications. Featuring
a unique isolated cavity
for the electrical switch
and wiring, the design
of the LLS eliminates
the possibility of
leakage and liquid contamination
of the electrical switch

EPC 110/120


EPC-110/120 Air/Fuel Ratio Control and Monitoring Systems for Carbureted, Stoichiometric Engines The Altronic EPC-110 and the EPC-120
are air/fuel ratio controllers for use on carbureted gas engines. These controllers utilize microprocessor technology, allowing a high level of sophistication
in control strategy, ease of programming and diagnostic capability. The EPC-110 is intended for stand-alone, off-engine, post- or wall-mounting. The EPC-120 is
intended for off-engine, panel mounting.

Both controllers are identical in operation. The EPC-110/120 is designed foruse on engines operating at or near a stoichiometric air/fuel ratio (lambda .95 –
1.05) and is ideally suited for application with 3-way catalytic converters.
The control approach of the EPC- 110/120 assures engine operation at the optimum lambda (exhaust
oxygen) setpoint determined to be the point of maximum catalytic
converter efficiency and minimum engine emissions. Once determined (through an analysis of the engine exhaust),
it is entered into the EPC-110/120 as the control setpoint. Using a sensor in the exhaust
stream to sense the O2 content, the unit begins to adjust the flow of fuel to meet
the proper exhaust oxygen setpoint(s) for minimum emissions. The full-authority
fuel control valve(s), mounted in the fuel line between the carburetor and the final
cut regulator, assures precise, repeatable control of the air/fuel ratio without resorting
to the potentially dangerous strategy of adding fuel to the air intake of the

Monitoring and protecting the engine and catalyst from high temperature-related damage or out-of-compliance operation is a key function of the EPC-110/120 system.
Critical temperatures are monitored against user-adjustable setpoints using type K thermocouples.

ALTRONIC  herby declares that equipment listed in this certification are designed and manufactured in conformance with the provisions of ATEX  directive 94/9EC when installed and maintained in accordance with the applicable ALTRONIC installation instructions with associated ALTRONIC components suitable for use in hazardous areas.



ATEX  stands for ATmosphères EXplosibles They apply to all kinds of, electrical or non-electrical equipment and safety devices as well as machines and industrial facilities located within potentially explosive atmospheres.



Through directive 94/9/EC that provides for the first time harmonized requirements for non-electrical and electrical equipment, equipment intended for use in environments which are potentially explosive due to dust hazards and protective systems. Safety devices intended for use outside explosive atmospheres which are required for or contribute to the safe functioning of equipment or protective systems with respect to risks of explosion are also included. This is an increase in scope compared to former national regulations for equipment and systems intended for use in potentially explosive atmospheres.



The ATEX directive consists of two EU directive describing what equipment and work environment is allowed in an environment with an explosive atmosphere.


ALTRONIC has certified a wide range of products under the CSA class 9098-01 MISCELLANEOUS-For Hazardous Locations 9098-01

Products for use in hazardous locations and for which specific guide headings have not been set up either because the product is new to CSA or because not many are certified or for other reasons.

The Certified equipment appearing in this classification is judged to comply with the applicable requirements of the NFPA 70 National Electrical Code (NEC), for use in hazardous locations.


Area Classification Systems


North America


In North America, hazardous locations have traditionally been defined by the following combination of Class and Division:

Class I - A location where a quantity of flammable gas or vapor, sufficient to produce an explosive or ignitable mixture, may be present in the air.

Class II - A location made hazardous by the presence of combustible or electrically conductive dust, including Groups E (metal dust), F (coal dust) and G (grain dust).

Class III - A location made hazardous by the presence of easily ignitable fibres or flyings in the air, but not likely in sufficient quantities to produce ignitable mixtures.


Division 1 - A location where a classified hazard is likely to exist.

Division 2 - A location where a classified hazard does not normally exist but is possible under abnormal conditions.

For example: In Class I, Division 1, flammable gases or vapors could exist in quantities sufficient to produce an explosive or ignitable mixtures under normal operating conditions; in Class I, Division 2, flammable volatile liquids are normally confined within closed containers from which they can only escape as a result of accidental rupture.


Altronic operates a Quality Management System which complies with the requirements of ISO 9001:2008 for the following scope of
registration The Registration covers the Quality Management System for the design, manufacturing and assembly of electrical and electronic equipment for internal combustion engines and the design, manufacturing and assembly of industrial
instruments for measuring, display and control.


The ISO 9001:2008 is the basis of system quality management as it is an international standard that focuses on all elements of
quality management that a company needs to have an effective system that allows you to manage and improve the quality of your products or services.


ISO is a non-governmental organization that forms a bridge between the public and private sectors. On the one hand, many of its
member institutes are part of the governmental structure of their countries, or are mandated by their government. On the other hand, other members have their roots uniquely in the private sector, having been set up by national partnerships of industry associations.


Therefore, ISO enables a consensus to be reached on solutions that meet both the requirements of business and the  broader needs of society.


ALTRONIC operates an Environmental Management System which complies with the requirements of ISO 14001:2004 for the following scope of registration:

The Registration covers the Environmental Management System for the design, manufacturing and assembly of electrical and electronic equipment for internal combustion engines and the design, manufacturing and assembly of industrial instruments for measuring, display and control.


ISO 14001 is an internationally accepted standard that sets out how to implement an effective environmental management system (EMS). The standard is designed to manage the delicate balance between maintaining profitability and reducing environmental impact. the commitment of the entire organization allows to reach both.


Theimplementation of ISO 14001 environmental management system creates a systematic approach to environmental activities and improved business processes aimed at:


 • Define the significant environmental aspectsand impacts for the organization.

• Stateobjectives and goals of environmental performance.

• Establish environmental management programs.

• Define the organization's environmental policy.

• Strengthen personal responsibility to the environment

CE approved

CE is a mandatory conformity mark for products placed on the market in the European Economic Area (EEA). With the CE marking on a product, the manufacturer ensures that the product conforms with the essential requirements of the applicable EC directives



CE marking is a declaration by the manufacturer that the product meets all the appropriate provisions of the relevant legislation implementing certain European Directives. CE marking gives companies easier access into the European market to sell their products without adaptation or rechecking. The letters CE stand for "Conformité Européenne" which means "European Conformity".
They are a declaration by the manufacturer that his product meets the requirements of the applicable European Directive.


Although CE does not necessarily implies a quality seal per se. It might be considered in some extend a quality guaranty as the European standards set for products marked under this mark are really high.
