Diesel, Petrol or Gas Powered Generator Control Module

3 Attempt Automatic Generator Control Module AECM 103FBS

PROTECTION

• Overheat engine shutdown.
• Low Oil Pressure Shutdown.
• Over / Under Speed Shutdown. (Double engine protection from under and over speed. Reprogrammable frequency limits for 50 / 60Hz AC alternators. This protection can be disabled by us if no AC alternator to control but only engine).
• Emergency stop Input “alarm”(can be also used as a low fuel S/D, etc).
• Protection from 2nd and follow-up dangerous starter motor engagements with engine running via oil pressure switch sensed if AC alternator has failed to generate.
• "Fail to start" latching mode.
• Fuel/Starter/Load/Preheat outputs short circuit self-protection with polyfuse built-in.

FEATURES

• Remote start and stop via input 1. Generator will be running as long as input 1 is grounded.
• Manual start / stop.
• Over / under frequency (speed) automatic protection. This feature is available for 60Hz or 50Hz generators, please tell us which one is yours so we could supply the right part.
• Configurable Fuel solenoid type. From N/C to N/O via input 9. This feature is optional, please ask for details. The module is currently set for N/C type.
• 3 automatic attempts for reliable start. Any number of attempts available, any duration, please ask.
• Automatic load control. After a successful start the control module will be waiting (programmable time) until the generator gets upto speed and stabilise its parameters, then automatically connect the load to the AC alternator output. It will also remove the load automatically in the event of any identified fault or if the "stop" button is pressed / remote start signal has been switched off. By pressing “Stop” button, the load will be disconnected immediately leaving generator running for a cooling down time. If the "Run" button has been pressed again during the cooling down process, the cooling down process will be cancelled and the load automatically connected back to the running generator. The cooling down time is ajustable for up to 4 min. and can be reprogrammed. This feature is optional and not included into the program, please contact us for details.
• Configurable oil pressure switch input type (N/C or N/O type supported, N/C is set by default).
• Configurable water temperature switch input type (N/C or N/O type supported, N/O is set by default).
• Configurable emergency stop input. N/C or N/O type supported, N/C is set by default.
• Configurable preheat output. (Can be enabled or disabled via terminal 13).This feature is optional and not included into the program. Please contact us for details.
• 12/24V battery power supply. (up to 33V max.)
• Extremely low power consumption in stand by mode. (Approx.20 mA)
• Small compact design, can be fitted into any control panel.
• It has no alternative on the market (compare features and price)

• Automatic Battery sensor can be fitted (at extra cost) allowing to automatically start the generator if the battery voltage drops below the set level and stop it when the battery is fully charged.These voltage limits are reprogrammable, 12V / 24V batteries are supported. Please send us your enquiries.

DESCRIPTION

The Model AECM103FBS is an Automatic Generator Control Module designed to automatically start and stop the engine. It will indicate the operational status and fault conditions, automatically shut down the engine and indicate the start engine failure by a flashing LED on the front panel. Other simultaneous faults are indicated by steady LED.

0.5 second after the fuel relay is energised, the 3 attempt start will begin its start sequence: the start relay will energise, feeding battery +ve (on terminal 6) to terminal 7 and thence on to the starter circuit. The crank period is set for 12 seconds. If the engine has not fired by the end of 1st attempt, the starter is turned off for 20 sec. period. The sequence will then repeat up to a maximum number of start attempts During engine cranking and for a short time afterwards the protective hold-off timer (programmable) is active and the relevant alarms inputs are inhibited. This enables the engine to start and achieve normal running conditions. Once the timer has expired (reprogrammable), the inputs are enabled providing normal protection from the module.

The starter relay can only energise for 2nd and 3rd crank cycle if “Low Oil Pressure” is sensed, to confirm that the engine is stationary. This is designed to prevent damage to the starter and ring gear in the event of the control module not sensing that the engine has started (i.e. terminals 11 and 12 are not connected to the alternator AC output or AC alternator is faulty).

Following a successful start, sensed when AC alternator's voltage rises above 40% of nominal, the crank relay is de-energised and latched out to prevent reengagement of the starter with the engine running.

Should the engine still fail to start after the maximum number of attempts,  START FAIL is displayed and the starter is latched out until reset via stop button. Operation of the module is via coupled push buttons, mounted on the front panel with START and STOP/AUTO positions or via

remote start terminal 1.

Relay outputs are provided for:

Fuel Solenoid Output

Start Output

Load control output (optional)

Glow plug control output (optional)

The relays supply positive plant supply out.

Configurable inputs are available for:

Low Oil Pressure.

High Engine Temperature.

Remote Start.

Speed sensor can be disabled via a program, please ask.

AC alternator monitor.

Spare alarm input (N/C) for an emergency stop button.

This allows the module to safely  stop the engine at ANY time.

Multiple alarm channels are provided to monitor the following:

Under/Over speed (speed fault)

Low oil pressure

High engine temperature

Fail to Start 

Cranking

Fuelling

The AECM 103FBS series modules have been designed for front panel mounting.

The module is fitted into the cut-out with the fixing clips removed.

These are then fitted from the rear.
