Description
Tooth number of the engine, it is for judging
starter crank disconnect conditions and
inspecting engine speed.
When engine speed has fallen below the set
value and delay time is expired, "Under
Speed Shutdown" is active. It will initiate a
shutdown alarm signal.
When engine speed has exceeded the set
value and delay time is expired, "Over
Speed Shutdown" is active. It will initiate a
shutdown alarm signal.
It is delay time after speed signal lost, if the
delay time is set as 0s, it is only warning not
shutdown.
When battery voltage has exceeded the set
value and remains for 20s, it will initiate a
warning alarm signal. It is only warning, not
to shutdown the generator.
When battery voltage has fallen below the
set value and remains for 20s, It will initiate a
warning alarm signal. It is only warning, not
to shutdown the generator.
As generator is normal running, when
voltage difference between alternator
D+(WL) and B+ exceeds the set value and
remains for 5s, it will initiate a charging
failure warning alarm signal.
Maximum times of crank attempts. When it
reaches this number, controller will send
start failure signal.
Crank disconnect conditions: generating,
speed and oil pressure, aiming at disconnect
the motor and engine as soon as possible.
When engine speed is higher than the set
value, then it is considered that genset start
is successful, and starter will be
disconnected.
During starting process, when generator
voltage is higher than the set value, starter
will be disconnected.
During starting process, when generator oil
pressure is higher than the set value, then it
is considered that genset start is successful,
and starter will be disconnected.
When crank disconnect condition contains
oil pressure, if engine oil pressure is higher
than pre-set value and delay time is expired,
then it is considered that genset start is
successful, and starter will be disconnected.
Over volt shutdown setpoint and delay
value; when it is set to 620V, over voltage
shutdown signal shall not be detected;
Under volt shutdown setpoint and delay
value; when it is set to 30V, under voltage
shutdown signal shall not be detected;
