No.
Type
Description
36 MSC Too Few Sets
When the controller detects fewer modules on the MSC link than the
minimum number configured in the unit, it will initiate a warning alarm.
There are 2 possible reasons: a) Communication line between the
controllers disconnects, which interrupts communication.
b) Other parallel gen-sets controllers have not been powered on.
37 Loss of Excitation
When loss of excitation detection is active and the controller detects
that the genset negative reactive power has exceeded the pre-set value,
it will initiate a warning alarm.
5.2
SHUTDOWN ALARMS
When controller detects shutdown alarm, it will send signal to open breaker and shuts down generator.
Table 8 Shutdown Alarms
No.
Type
Description
1
Emergency Stop
When the controller detects an emergency stop alarm signal, it will
initiate a shutdown alarm.
2
Over Speed
When the controller detects that the generator speed has exceeded the
pre-set value, it will initiate a shutdown alarm.
3
Under Speed
When the controller detects that the generator speed has fallen below
the pre-set value, it will initiate a shutdown alarm.
4
Loss of Speed Signal
When the controller detects that the engine speed is 0 and the action
select “Shutdown”, it will initiate a shutdown
alarm.
5
Gen Over Frequency
When the controller detects that the genset frequency has exceeded
the pre-set value, it will initiate a shutdown alarm.
6
Gen Under Frequency
When the controller detects that the genset frequency has fallen below
the pre-set value, it will initiate a shutdown alarm.
7
Gen Over Voltage
When the controller detects that the generator voltage has exceeded
the pre-set value, the controller will initiate a shutdown alarm.
8
Genset Under Voltage
When the controller detects that the genset voltage has fallen below the
pre-set value, it will initiate a shutdown alarm.
9
Fail to Start
If the engine does not fire after the pre-set number of attempts, it will
initiate a shutdown alarm.
10 Gen Over Current
When the controller detects that the genset current has exceeded the
pre-
set value and the action select “Shutdown”, it will initi
ate a
shutdown alarm.
11 Maintenance Due
When count down time is 0 and the action select “
Shutdown
”,
it will
initiate a shutdown alarm.
12 ECU Shutdown
If an error message is received from ECU via J1939, it will initiate a
shutdown alarm.
13 ECU Fail
If the module does not detect the ECU data via J1939, it will initiate a
shutdown alarm.
