Stop Failure: When cool down times out, the fuel relay opens and the timer for Stop delay begins.
When it times out, if controller detects that the voltage and frequency of generator or oil pressure of
engine are greater than the preset values, the Fail to stop LED illuminates and the LCD displays Fail to
stop.
NOTE:
After stop failure, the controller will not energize the crank relay output if
the failure has not been removed and the controller reset.
5.3 MAN control sequence:
Controller is in “MANUAL” mode.
Generator starting sequence:
Pressing “START” button the fuel relay energises, and operates the fuel solenoid of engine.After 300ms
delay, the start relay output is energized, the start motor engages and begins to crank. When the engine
speed reaches the crank cutout RPM, the start relay output is de-energized and the safety-on delay starts.
When the safety-on times out, if the controller detects that the parameters of the Genset such as voltage,
frequency, oil pressure and coolant temperature are normal, and no other failure is detected this indicates
the Genset has successfully started and running normally. The LCD displays the Genset Measurement
parameters.
When generator is running normally, GCB close/open relay will not close automatically. Manually close
the Gen switch, Gen is on load, the Gen Aux. Switch’s contact feeds back the signal to a configurable
input on our controller, Gen. Normal LED illuminates.
5.4 The start and stop sequence of engine whose fuel solenoid is N. O. type:
Start control sequence:
During the starting sequence, the fuel relay of controller will not energize, fuel solenoid is no power, so
no signal is required for fuel solenoid to activate.
Stop control sequence:
During the stopping sequence, the fuel relay energizes, fuel solenoid is on power and energizes, and
the engine begins to stop. After a delay (same as stop delay) fuel relay de-energizes, disconnecting the
supply for the fuel solenoid.
Other control sequence is same as engine whose fuel solenoid is N. C. type.
NOTE:
When the controller is in “MANUAL” mode and Gen. Normal LED
illuminates, you must define one configurable input as Gen Aux. Switch
Closed and connect the switch’s N.O. Aux. contact signal to this port,
otherwise the GCB closed LED will not illuminate.
