When engine speed is over this value for 2s,
over speed is considered; controller
issuesover speed alarm shutdown signal;
Alarm delay for gen under/over voltage.
Gen Over Volt limit
for Shutdown
When generator voltage is higher than this
threshold and lasts for the set gen abnormal
delay, then it shall consider over voltage and
shutdown alarm will be initiated.
(No detection for over volt signals if it is set
as 60000V)
Gen Under Volt limit
for Shutdown
When sample voltage falls below this
threshold and lasts for the delay time, it is
considered under voltage and shutdown
alarm shall be initiated.
(No detection for under volt signals if it is set
as 30V)
Level High to
disable Fuel Pump
When fuel level is over the pre-set value for
2s, fuel pump is off;
Level Low to enable
Fuel Pump
When fuel level is under the pre-set value for
2s, fuel pump is on;
When generator frequency falls below this
threshold (not 0) and lasts for the delay time,
then it is considered under frequecy and
shutdown alarm signal will be initiated.
When generator frequency is over than this
threshold and lasts for the delay time, then it
is considered over frequecy and shutdown
alarm signal will be initiated.
Under Frequency
Shutdown Delay
When generator frequency falls below this
threshold (not 0) and lasts for the delay time,
then it is considered under frequecy and
shutdown alarm signal will be initiated.
Over Frequency
Shutdown Delay
When generator frequency is over than this
threshold and lasts for the delay time, then it
is considered over frequecy and shutdown
alarm signal will be initiated.
Temp. High
Shutdown Value
When outside temp. sensor is above this
value, and Temp. High signal is issued; This
is detected only after safety on delay and
only for externally connected Temp. sensor;
When set value is 140, Temp. High signal is
not issued (only for Temp. sensor, excluded
