Running feedback Oil pressure setpoint (parameter 6175).
Running feedback EIC (engine communication).
Emergency stop
Alarm Alarms with shutdown" or "trip and stop" fail class.
Stop push-button on display Manual mode.
Modbus stop command Manual mode.
Binary stop input Manual mode.
Deactivate the "auto start/stop"
Auto mode in the following genset modes: Island operation or load
takeover mode.
NOTE: If the MPU input is to be used to remove the starter, it has
to be set up in parameters 6171, 6172, 6173, 6174.
Parameter Setpoints Related To The Start Sequence:
- Crank failure alarm (parameter 4530 Crank failure)
If MPU is chosen as the primary running feedback, this alarm will be raised if the
specified rpm is not reached before the delay has expired.
- Run feedback failure (parameter 4540 Run feedback fail)
If running is detected on the frequency (secondary), but the primary running feedback,
for example, digital input, has not detected running, this alarm will be raised. The delay
to be set is the time from the secondary running detection and until the alarm is raised.
- Hz/V failure (parameter 4560 Hz/V failure)
If the frequency and voltage are not within the limits set in parameters 2110, 2111,
2112 after the running feedback is received, this alarm is raised when the delay has
expired.
- Start failure alarm (parameter 4570 Start failure)
The start failure alarm occurs, if the genset has not started after the number of start
attempts set in parameter 6190.
- Start prepare (parameters 6180, 6181, 6182, 6183, 6184, 6185, 6186 Starter)
Normal prepare: the start prepare timer can be used for start preparation purposes, for
example, pre-lubrication or pre-glowing (glowing before start). The start prepare relay is
activated when the start sequence is initiated and deactivated when the start relay is
activated. If the timer is set to 0.0 s, the start prepare function is deactivated.
Extended prepare: the extended prepare will activate the start prepare relay when the
start sequence is initiated and keep it activated when the start relay activates until the
specified time has expired. If the extended prepare time exceeds the start ON time, the
start prepare relay is deactivated when the start relay deactivates. If the timer is set to
0.0 s, the extended prepare function is deactivated.
Start ON time: the starter will be activated for this period when cranking. Start OFF
time: the pause between two start attempts.
