the pre-set over voltage threshold
Indicates that genset L1(R) Phase voltage has fallen
below pre-set under voltage threshold.
Indicates that genset L2(Y) Phase voltage has fallen
below pre-set under voltage threshold
Indicates that genset L3(B) Phase voltage has fallen
below pre-set under voltage threshold
Alternator phase sequence is not correct
Indicates that genset output frequency has exceeded the
pre-set threshold
Indicates that genset output frequency has fallen below
the pre-set threshold
Indicates that genset current has exceeded the pre-set
shutdown threshold
Indicates that the measured kW load rating has exceeded
the pre-set threshold
Load on any phase is greater or less than other phases by
a threshold value
Indicates that genset speed has exceeded the pre-set
over speed threshold
Indicates that genset speed has exceeded the pre-set
gross over speed threshold
The engine speed has fallen below the pre-set RPM
Indicates that there was 100% load on the genset for one
hour in the time interval of last 12 hours
The battery voltage has fallen below the pre-set threshold
The battery voltage has exceeded the pre-set threshold
Indicates that engine running hours has exceeded the pre-
set hours limit or maintenance due date has occurred, and
filter servicing is required.
Indicates the Mains unhealthy condition
Generic fault
If signal is not received when MPU speed signal source is
selected in engine running condition.
If engine speed sensing through sensor is enabled and
GCU is not getting any signal from speed sensor.
If the voltage generated during the auto-exercise is too
high
If the voltage generated during the auto-exercise is too
low
If the alternator signal is lost
If the voltage generated during the auto-exercise is too
low
If ambient temperature is less than 40°F and auto
exercises time occurs, GCU skips exercise and gives this
