3 Attempt Automatic Generator Control Module AECM104FRSi
with wireless start/stop function
MADE IN THE UK
The Model AECM104FRSi is an Automatic Generator Control Module designed to automatically [remotely] or manually 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 flashing "START FAIL" LED on the front panel. Other faults are indicated by steady LED.
- Operation of the module is via 2 pos. rocker switch mounted on the front panel with STOP/AUTO-RUN positions.
- Wired remote control of the module is via terminal 1.
- Wireless control of the module is via key fob (supplied).
WIRED REMOTE / LOCAL CONTROL
For wired remote control: Front switch is in “AUTO” position; remote start
[input 1] is grounded;
For local control: front
switch is in “RUN” position; [input 1] is unused.
0.5 Second after the fuel relay is energized [terminal 5], the 3 attempt start will begin its start sequence: the start relay will energize, feeding battery +ve (on terminal 7 to terminal 2 and thence on to the start circuit. If the engine has not fired by the end of 1st attempt, the starter is turned off for a resting period. The sequence will then repeat up to a maximum number of start attempts. Following a successful start, sensed when AC alternator's voltage rises above 40% of nominal, the start relay is de-energized and latched out to prevent reengagement of the starter with the engine running.
Rocker switch is in STOP/AUTO position.
Terminal 1: (wired remote start is unused)
Make sure there are no metal doors/walls/other metal shields between you and controlled generator. Any metal obstacle can significantly reduce the working distance between the transmitter (key fob) and controlled generator.Press RED button on a key fob for 1 sec and release it. The generator should try to start within a few seconds.Press RED button to stop the set. If your generator doesn't respond - try to stretch out the aerial on key fob and press the RED button again. If unsuccessful-come closer to controlled generator.
PRE-HEAT CONTROL (OPTIONAL)
For wired remote start: front switch is in “AUTO” position, pre-heat enabler [DIP switch 1] is ON, remote start [input 1] is grounded;
For local start: Pre-heat enabler [DIP switch 1] is ON, front switch is in “RUN” position;
For wireless start: front switch is in “AUTO” position, pre-heat enabler [DIP switch 1] is ON, remote start [input 1] is unused;
When 10 second pre-heating cycle is timed out and flashing LED on the panel is turned off, the module will begin its start sequence: the fuel solenoid relay is energized feeding battery +ve on terminal 7 to terminal 5 and thence to the fuel solenoid circuit, the start relay will energize, feeding battery +ve on terminal 7 to terminal 2 and thence on to the start circuit. If the engine has not fired by the end of 1st attempt, the starter is turned off for a resting period. The sequence will then repeat up to a maximum number of start attempts. Following a successful start, sensed when AC alternator's voltage rises above 40% of nominal, the crank relay is de-energized and latched out to prevent re-engagement of the starter with the engine running.
LOAD CONTROL (OPTIONAL)
After a successful start, when engine's parameters are settled (when 7 sec time delay provided by hold-off timer is timed out), the Load Control Output will energize and send a signal from terminal 10 to an external power relay. This energizes a contactor which will connect the AC alternator output to the load. The run time before accepting load and the run time after relieving load (while generator is still running and is ready to accept the load again if the remote/local start signal is switched back on) are reprogrammable with a limit of 255 sec [4.25 min] max.(for each timer).
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” position of front switch or via terminal 1 / key fob if the engine start was initially made via remote start signal.
The starter relay can only energize 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). 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” position of front switch or via terminal 1 if the engine start was initially made via remote start signal.
Relay outputs are provided for:
- Fuel Solenoid output
- Starter motor output
- Preheat output (optional)
- Load control output (optional)
The relays supply positive plant supply out.
Configurable inputs are available for:
- Low Oil Pressure.
- High Engine Temperature.
- Wired Remote Start.
- AC alternator monitor.
- Emergency Stop input [N/O] to give protection expansion.
- Pre-heat mode enabler (optional)
Multiple alarm channels are provided to monitor the following:
- Under/Over speed (speed fault) This sensor can be enabled / disabled via DIP switch 2
- Low oil pressure
- High engine temperature
- Fail to Start
- Emergency stop button status
The AECM 104FRSi series modules have been designed for front panel mounting. The module is fitted into the 68X68mm cut-out with the fixing clips removed. These are then fitted from the rear.

Max. working distance (in open space) up to 100m (not guaranteed)
Important! Should you wish to use remote start via key fob only-don't fit the control module into metal enclosure.
As we all know the metal shields can significantly block all radio signals which is shortening working distance.
All optional inputs / outputs available at extra cost, please contact us if you need a pre-heat function, battery voltage sensor (BVS) or load control output.
