Alarm Type
23
Voltage SHD 1
Alarm when controller detects voltage single
harmonic distortion value is greater than set value.
Disabled
24
Voltage SHD 2
Disabled
25
Loss
of
Excitation 1
Alarm when controller detects the absolute value
of genset negative reactive power is greater than
the set value.
Warn
Always active
26

Disabled
27
Low
Power
Factor 1
Alarm when controller detects genset power
factor is lower than set vale.
Warn
It is active after gen has
closed.
28
Low

Factor 2
Disabled
29
Freq./Volt Fault
Frequency/voltage alarm will be initiated when
controller starts and can’t meet load conditions
after load stable delay.
Block
It is active after starting.
Engine Protection
1
Start Failure
Alarm when genset not reach load condition after
starting and start wait delay is over.
Block
It is active after starting.
2
Stop Failure
Alarm when it detects generator signal after stop
wait delay is over.
Warn
It is active after stop
wait delay.
3
Sync. Failure
When controller not detect synchronous signal
during set time, it will initiate a warning alarm.
Warn
It
is
active
in
synchronization.
4
Engine Fault
When controller detects engine fault input is
active, it will initiate a warning alarm.
Block
Always active.
5
No
Running
Feedback Fault
When running feedback function is enabled, if
controller detects that voltage and frequency meet
crank disconnect conditions after starting, but
running feedback input is inactive, running
feedback fault alarm will be initiated.
Warn
It is active after starting.
6
External Start
In semi-auto mode, when controller detects
generator signal, alarm signal will be initiated;
In manual mode, alarm signal will be initiated after
external start and close with load.
Indication
It is active at standby.
7
External Stop
In manual mode, controller will send alarm signal
in external stop.
Indication
It is active at stop.
