MANUAL START/STOP
a)
Press
to start genset. It will detect complete start and accelerate to high-speed running
automatically. With high temperature, low oil pressure, over speed and volt abnormal during
genset running, controller can protect it to stop quickly (Please refer to Start Sequence b-g).
b)
Press
to stop the running genset (Please refer to Stop Sequence b-f).
NOTE:
a)
The genset can be stopped manually in remote start status; at this time, remote input is inhibited and it will be
active when remote input is closed again.
b)
After start conditions are satisfied, accumulative running timer will be initiated; at the same time, the last
blinking decimal of nixie tube indicates that genset works normally.

PROTECTION
1)
Low Oil Pressure: detect after Safety On, Alarm Stop when Low Oil Pressure input is active and
lasts for 2s.
2)
High Temperature: detect when start, Alarm Stop when High Temperature is active and lasts
for 2s.
3)
Over Speed: detect when start, Alarm Stop after duration exceeds Over Speed Stop Delay.
4)
Gen Over Volt: Alarm Stop when the controller detects genset voltage exceeds overvoltage
value and delay exceeds abnormal delay.
5)
Gen Under Volt: Alarm Stop when the controller detects genset voltage less than under voltage
value and delay less than abnormal delay.
6)
Emergency Stop: ETS output immediately when Emergency Stop is active, in the meanwhile
fuel, preheat and start signal are cut off and Emergency Shutdown Alarm Signal is sent.
7)
Fail to Start: Alarm Stop when start failed in preset start times.
8)
Gen Under Frequency: When genset is normal running, controller detects gen frequency falls
below under frequency value and the “under frequency” delay has expired, under frequency
shutdown alarm will be sent.
9)
Gen Over Frequency: Detection when start genset, if gen frequency exceeds over frequency
value and the “over frequency” delay has expired, over frequency shutdown alarm will be sent.
