Oil Pressure Open
Circuit
When the controller detects that the oil pressure sensor is open
circuit and the action select “Shutdown”, it will initiate a shutdown
alarm.
When the controller detects that the oil pressure has fallen below
the pre-set value, it will initiate a shutdown alarm.
Level Sensor Open
Circuit
When the controller detects that the level sensor is open circuit
and the action select “Shutdown”, it will initiate a shutdown alarm.
Flexible Sensor 1
Open Circuit
When the controller detects that the flexible sensor 1 is open
circuit and the action select “Shutdown”, it will initiate a shutdown
alarm.
When the controller detects that the sensor 1 value has exceeded
the pre-set value, it will initiate a shutdown alarm.
When the controller detects that the sensor 1 value has fallen
below the pre-set value, it will initiate a shutdown alarm.
Flexible Sensor 2
Open Circuit
When the controller detects that the flexible sensor 2 is open
circuit and the action select “Shutdown”, it will initiate a shutdown
alarm.
When the controller detects that the sensor 2 value has exceeded
the pre-set value, it will initiate a shutdown alarm.
When the controller detects that the sensor 2 value has fallen
below the pre-set value, it will initiate a shutdown alarm.
When digit input port is set as shutdown and the alarm is active, it
will initiate a shutdown alarm.
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 “Shutdown”, it will initiate a shutdown alarm.
Negative Sequence
Current
When the controller detects the imbalance current has exceeded
the pre-set value and the action select “Shutdown” it will initiate a
shutdown alarm.
When the controller detects fewer modules on the MSC link than
the minimum number configured in the unit, it will initiate a
shutdown 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.
When the controller detects the same ID on the MSC Bus, it will
initiate a shutdown alarm.
When the controller detects a phase rotation error, it will initiate a
shutdown alarm.
When the controller detects a bus phase rotation error, it will
initiate a shutdown alarm.
When the controller detects the voltage difference between
generator and bus, it will initiate a shutdown alarm.
When the controller detects that the genset negative reactive
power has exceeded the pre-set value, it will initiate a shutdown
alarm.
