GENSET CONTROLLER

o
Allows the engine to stabilise at full speed before going on load. Oil pressure
and Over-speed are monitored. The display shows ‘Warm Up’ with a
countdown time.
RUNNING
o
The display shows ‘Running’. Operating parameters are scrolled onto the
display.
5.4.2
To stop the genset
Push the
STOP
button briefly.
The unit will perform a stopping sequence as follows:
STOPPING
o
The display will show ‘Stopping’ with a countdown time.
o
If ETR fuel control has been selected the Fuel output will be de-energised.
o
If ETS fuel control has been selected then the Fuel output will be energised for
the Max Fuel Time or until the engine stops. The stopping process will retry if
the engine fails to stop the first time. During the ‘ETS Rest period’ the Fuel
output is deactivated.
o
The fuel output is controlled until the engine stops rotating and oil pressure
decays. If the Oil Pressure has not decayed by the end of the ‘Max Fuel Time’,
the fuel output is deactivated and the controller waits until the oil pressure has
decayed, or for the remainder of the ‘Stop Time’. The speed must remain at
zero and the oil pressure must be below the alarm set point for the ‘Stop Rest
Time’ before the engine is considered stopped.
o
If the genset does not stop then the alarm output is activated and ‘STOP FAIL’ is
displayed on the LCD.
READY
o
The engine has stopped and is ready to start again as required.

Autostart Engine Control
If the Autostart input is activated, the unit will initiate an Autostart sequence. The
sequence is similar to the manual start and stop sequences above with the following
additions.
An adjustable Start Delay follows the Autostart input activation. This is usually
configured to avoid nuisance starting. The Display shows “Starting” with a
countdown value. For long start delays, the start time units may be set to minutes.
If the autostart restores for more than the Start Restore time, then the start
sequence is aborted.
