No.
Type
Description
31 MSC ID Error
When the controller detects the same ID on the MSC Bus, it will initiate
a shutdown alarm.
32
Gen Phase Sequence
Wrong
When the controller detects a phase sequence wrong, it will initiate a
shutdown alarm.
33
Volt Bus Phase
Sequence Wrong
When the controller detects a bus phase sequence wrong, it will initiate
a shutdown alarm.
34 Volt Bus Error
After synchronized-closing, when the controller detects the voltage
difference between generator and bus, it will initiate a shutdown alarm.
35 Loss of Excitation
When the controller detects that the genset negative reactive power
has exceeded the pre-set value, it will initiate a shutdown alarm.
5.3
TRIP AND STOP ALARMS
Once trip and stop occurred the controller will start the cooling delay and allow the engine to cool
before shutting down the engine.

Type
Description
1
Gen Over Current
When the controller detects that the genset current has exceeded the
pre-
set value and the action select “Trip and Stop”, it will initiate a trip
and stop alarm.
2
Maintenance Due
When count down time is 0 and the action select
“Trip and Stop”, it will
initiate a trip and stop alarm.
3
Reverse Power
If reverse power detection is enabled, when the controller detects that
the reverse power value (power is negative) has exceeded the pre-set
value and the action select
“Trip and Stop”, it w
ill initiate a trip and stop
alarm.
4
Over Power
If over power detection is enabled, when the controller detects that the
over power value (power is positive) has exceeded the pre-set value
and the action select
“Trip and Stop”, it will initiate a trip an
d stop
alarm.
5
Digital Input
When digit input port is set as
“Trip and Stop”
and the alarm is active, it
will initiate a trip and stop alarm.
6
Earth Fault
If earth fault detection is enabled, when the controller detects that the
earth fault current has exceeded the pre-set value and the action select
“Trip and Stop”, it will initiate a trip and stop alarm.
7
Imbalance Current
If earth imbalance current detection is enabled, when the controller
detects the imbalance current has exceeded the pre-set value and the
action select
“Trip and
Stop”, it will initiate a trip and stop alarm.
8
Loss of Excitation
If loss of excitation fault detection is enabled, when the controller
detects that the genset negative reactive power has exceeded the
pre-set value, it will initiate a trip and stop alarm.
