3.2.7 STOP TIME
Maximum time (in seconds) of the stop by excitation (stop electromagnet). Once
it detects that the engine has stopped, the stop by excitation output is
deactivated.
3.2.8 LOW OIL PRESSURE DELAY
Time, from start-up, until the low oil pressure alarm is taken into account.
3.2.9 HIGH WATER TEMPERATURE DELAY
Time, from start-up, until the low water pressure alarm is taken into account.
3.2.10 AUXILIARY INPUT DELAY
Time, from start-up, until the auxiliary input alarm is taken into account.
If you select delay time equal to zero the auxiliary input is always evaluated, even
when the engine is not running.
NOTE
For engines with stop by excitation congured as PR/PE in which the emergency
stop disables by hardware the use of a PC used as PE. The emergency pushbut-
ton has to be wired to the AUX input rather than to the PEM so that the PC
output is not disabled and can perform the stop by excitation. In this case you
must set the delay to 0 so that the input is always checked. This problem does
not exist for the PE/PD conguration, and you may wire the emergency pushbut-
ton to the PEM input.
3.2.11 FREQUENCY THRESHOLD FOR DETECTING START-UP
Percentage of the scheduled frequency as of which the engine will be considered
started. The engine-running LED will come on when the engine is put in motion
but the genset will not consider that it has started until it exceeds this threshold.
3.2 PROGRAMMING BY USB
By connecting a USB and the conguration software, you can program some of
the control unit’s parameters as detailed below:
3.2.1 NUMBER OF START-UPS
Sets the number of start-up retries automatically performed by the control unit
before it signals a start-up failure.
3.2.2 TIME BETWEEN START-UPS
Time between starting retries (in seconds).
3.2.3 START-UP TIME
Maximum duration (in seconds) of the start-up signal if it detects that the genset
has not started up.
3.2.4 SPARK PLUG PREHEATING TIME
Duration of the spark plug preheating (default=0). This time is only applicable if
microswitch 4 is in the OFF position (preheating disabled). Otherwise, the times
set for microswitch 1 prevail (long/short preheating).
3.2.5 TIME FOR THE ACTIVATION OF THE GENSET’S BREAKER
Time from when it detects that the engine has started.
3.2.6 COOLING DOWN TIME
Time (in seconds) during which the engine will remain running to cool the unit,
after the genset’s breaker has been disabled, if cooling has been enabled (mi-
croswitch 5). To stop the genset and to skip the cooling time, simply press the
START button again while it is cooling.
