2 1 to 999 s Regular stop
[180 s] If the engine performs a normal stop (start request is disabled or change into
STOP operating mode) or a stop caused by an alarm of alarm class C/D, a
cool down with an opened GCB is carried out. This time is programmable.
The message "Cool down" is displayed and the LogicsManager command
variable 04.10 becomes TRUE.
Stop by a class 'C' or 'D' alarm
If the engine is stopped by an alarm of this alarm class, a cool down is carried
out with an opened GCB. This time is programmable.
Stop by a class 'E' or 'F' alarm
If the engine is stopped by an alarm of this alarm class, the engine is shut‐
down without a cool down immediately.
Notes
If a critical operation mode (
on page 244 ) is initiated, the time configured in critical mode postrun (param‐
eter 4109) will be used instead of the cool down time.
2 [Yes] A cool down will be performed if the genset is changed to STOP operation
mode.
No No cool down will be performed if the genset is changed to STOP operation
mode.
2
Yes A cool down will be performed if a start signal is disabled or a stop signal is
enabled.
[No] No cool down will be performed if a start signal is disabled or a stop signal is
enabled.
This parameter only applies to application mode
2 0 to 999 s Prior to a start sequence being initiated, the discrete output for the auxiliary
services prerun (LogicsManager 03.30) remains enabled for the configured
[0 s]
amount of time to permit engine related operations (i.e. open louvers) to be
performed.
While this discrete output is enabled the control screen will display the mes‐
sage "Aux.serv.prerun" for the configured time.
The auxiliary services discrete output disables when the operation mode is
changed from the MANUAL operation mode or, if engine speed is no longer
detected, when the discrete output for the auxiliary services postrun (Logi‐
csManager 03.31) is disabled.
CAUTION
During an emergency start this delay time "auxiliary prerun" is not initialized.
The engine will be started immediately.
2 0 to 999 s After each engine stop (the engine stop timer has expired), the discrete
output for the auxiliary services postrun (LogicsManager 03.31) remains ener‐
[0 s]
gized for an adjustable time (i.e. operate a cooling pump).
If the operating mode is changed from MANUAL to STOP or AUTOMATIC
without a start command the relay remains energized for this period of time.
The message "Aux.serv.postrun" will be displayed on the control unit screen.
In the "MANUAL" operating mode this relay output is not used.
