NOTE:
While cranking, engine ignites. The start motor will power off when the
output frequency of generator reaches the preset value (configurable
crank cutout value), or if there are one of the following conditions occur:
A. Generator
’
s voltage reaches 80% of rated voltage;
B. Cranking time
’
s up,
C. LOP switch is opened and the delay time
’
s up.
D. Oil pressure switch is opened or oil pressure is higher than crank
cutout value.
E. Cutout P-delay time
’
s up.
Controller can not implement crank procedure if the frequency of
generator reaches the preset value (configurable cranking cutout value)
or LOP switch is opened.
CAUTION:
To avoid damage to the start motor please make sure the generator’s
voltage is higher than the measurable value of controller while cranking,
since the crank cutout signal is sensed from the generator voltage and
frequency.
NOTE:
Above control procedure, assumes that one of configurable inputs has
been configured as Gen Aux. Switch Closed and connects the switch’s
N.O. Aux. contact signal to this port. If you do not configure an input as
Gen Aux. Switch Closed, then the GCB closed LED illuminates is only
an indication that the GCB close/open relay should have been closed.
If you have selected idle function, the idle relay will be closed at the same time as the crank relay is
closed. The timers of idle and safety-on delay will begin counting down at the same time, and in priority
to display the shorter one on the LCD, and the following procedure is the same as above.
During the crank period, if the engine can not ignite and controller will not output start signal during crank
rest, Fail to Start icon on LCD flashes at this time. Once crank rest timer times out the start relay
energizes once again and will attempt to start engine again.
The above procedure will be repeated until engine successfully ignites or reaches the preset number of
crank attempt. However, if any shutdown alarm occurs during crank, controller will stop cranking
immediately and only can be restarted after clearing failure and reset.
Fail to Start: when the above procedure repeats again and again and reaches the preset number of
crank attempt, the crank relay output is then de-energized. The failure LED illuminates and the LCD
displays Fail to Start.
CAUTION:
If Fail to Start occurs, operator must check the whole Genset system to
find out failure reason, only after clearing the failure can press
“STOP/RESET” button to relieve fault lock out status, and restart the
Genset.
Generator shutdown sequence:
When the remote start signal is deactivated, the timer for cool down is activated, When it times out, the
fuel relay de-energizes, the timer for cool down is activated,
