stopped when “ETS time” is set as 0;
Time between ending of ETS hold delay and
stopped when “ETS time” is not 0.
Pulse width of mains/generator switch on.
When it is 0, means output constantly.
Tooth number of the engine, for judging of
starter crank disconnect conditions and
inspecting of engine speed. See the installation
instructions.
The alarm delay of generator over voltage and
under voltage.
When generator voltage has exceeded the set
value and the “Gen abnormal delay” has
expired, Gen Over Voltage is active. When set
the value as 620V, the controller does not
detect over voltage signal.
When generator voltage has fallen below the
set value and the “Gen abnormal delay” has
expired, Gen Under Voltage is active. When set
the value as 30V, the controller does not detect
under voltage signal.
When engine speed has fallen below the set
value for 10s, Under Speed is active. It will
initiate a shutdown alarm signal.
When engine speed has exceeded the set value
for 2s, Over Speed is active. It will initiate a
shutdown alarm signal.
When generator frequency has fallen below the
set value but Not equal to 0 for 10s, Under
Frequency is active. It will initiate a shutdown
alarm signal.
When generator frequency has exceeded the
set value for 2s, Over Frequency is active. It will
initiate a shutdown alarm signal.
When the temperature value of the external
temperature sensor exceeds the set value,
“High Temperature” timer is initiated. Detecting
only after safety on delay has expired. If the set
value is 140, high temperature signal will not
be sent (this only concerns external
temperature sensor, not high temperature
signal via config. input port).
When the external pressure sensor value falls
