with remote wired/local start/stop function

Suitable for single and three phase generators.

Not suitable for petrol generators with manual choke.

DESCRIPTION

The Model AECM107 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. toggle switch mounted on the front panel with OFF-ON positions (Local Control).
• Wired remote control of the module is via terminal 1.

For wired remote control: toggle switch is in “OFF” position; remote start [input 1] is linked to battery negative;

For local control: front switch is in “ON” 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.

For wired remote start: toggle switch is in “OFF” position, pre-heat enabler [DIP switch 2] is ON, remote start [input 1] is linked to battery negative;

For local start: pre-heat enabler [DIP switch 2] is ON, toggle switch is in “ON” position;

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 energised feeding battery +ve on terminal 7 to terminal 5 and thence to the fuel solenoid circuit, the start relay will energise, 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-energised 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 “OFF” position of toggle switch or via terminal 1 / key fob if the engine start was initially made via remote start signal.

 NOTE

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 properly 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 “OFF” position of toggle 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 switch] to give protection expansion.
• Pre-heat mode enabler (optional)

• Under/Over speed (speed fault) This sensor can be enabled / disabled via DIP switch 1
• Low oil pressure
• High engine temperature
• Fail to Start
• Emergency stop button status

 The AECM107 series modules have been designed for DIN rail and/or flat surface panel mounting.
