6.3 TRIP AND STOP ALARMS
On initiation of the trip and stop condition the controller will de-energize the ‘Close Generator’
Output to remove the load from the generator. Once this has occurred the controller will start the
Cooling delay and allow the engine to cool before shutting down the engine.
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.
When count down time is 0 and the action select “Trip and Stop”, it
will initiate a trip and stop alarm.
If reverse power detection is enabled, when the controller detects
that the reverse power value (power is negative) has fallen below
the pre-set value and the action select “Trip and Stop”, it will
initiate a trip and stop alarm.
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 and
stop alarm.
When digit input port is set as “Trip and Stop” and the alarm is
active, it will initiate a trip and stop 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 “Trip and Stop”, it will initiate a trip and stop alarm.
Negative Sequence
Current
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.
When the controller detects that the genset negative reactive
power has exceeded the pre-set value, it will initiate a trip and stop
alarm.
When the controller detects that the mains frequency has
exceeded the pre-set value, it will initiate a trip and stop alarm.
When the controller detects that the mains frequency has fallen
below the pre-set value, it will initiate a trip and stop alarm.
When the controller detects that the mains voltage has exceeded
the pre-set value, it will initiate a trip and stop alarm.
When the controller detects that the mains voltage has fallen
below the pre-set value, it will initiate a trip and stop alarm.
When the controller detects that the ROCOF (rate of change of
frequency) has exceeded the pre-set value, it will initiate a trip and
stop alarm.
When the controller detects that vector shift value has exceeded
the pre-set value, it will initiate a trip and stop alarm.
