Alarm messages
The automatic system can process 64 alarms. Alarms 1 - 19 and 49
– 64 are variable from the text and from
the resolution, i.e. the texts and control of these alarms were specified with the P

parameterisation
program. They are controlled by contact inputs (connections 1 to 14 unused inputs of the additional relay
unit) or by internal flags (controller impeded, analogue channel limit value too high, etc.). The parameterisa-
tion is described in the service manual. Because of the parameterisation, deviations from the following de-
scription can exist.
The alarms are basically divided into three groups:
Alarms that are only monitored delayed after start-up of the motor (e.g. low oil pressure). The release can
be recognised on the green 'monitoring On' display.
Alarms that are also monitored when the motor stops (e.g. battery undervoltage), except in the Off operat-
ing mode. They are designated as
without delay
.
The alarm messages 13 and 14 are always monitored, even in the Off operating mode.
They are used for
messages (e.g. leaks). The horn is not switched on in the Off operating mode, but the alarms are not in-
cluded in the collective alarm. They behave like normal alarms if an active operating mode (so not Off) is
selected.
The alarms are configured as follows:
Alarm is active or locked
Contact is in standby current or operating current,
Delayed or undelayed monitoring
Warning or switching-off function
In addition for warning alarms: With or without generator switch-off and with Stop after run-on time gener-
ator switch-off in automatic operation.
If the generator is switched off due to a warning alarm in automatic operation, the engine is stopped after the
idle time and the automatic system is locked.
For contact inputs, the respective alarm is triggered with the closing (operating current circuit) or with the
opening (standby current circuit) of the signal contact against negative potential, and for analogue signals, with
the exceeding or falling below of the set limit values. Alarms 11 to 14 can also be parametrised as a failsafe
signal on output relays, i.e. the respective relay attracts if the alarm is not pending.
