Acknowledge Alarm Messages
WARNING
The engine may start unintentionally if an alarm, which caused the engine to shut down, is acknowledged and an
enabling is still present. Before acknowledging the alarm, check the cause of the alarm, in order to protect operating
personnel located in the vicinity of the system against injuries, and to protect the engine against unintentional destruc-
tion.
⇒
If the cause of the alarm is not known or is unclear, NEVER press the acknowledge push-button! The destruction of
the engine cannot otherwise be ruled out !
By pressing the "RESET" push-button, the output of the centralized alarm and the alarm messages on the LC
display are acknowledged according to the following logic:
NOTE
In order to acknowledge alarm messages via terminal 6, the "acknowledgement" function must be assigned to this
terminal.
An alarm cannot be acknowledged until its reason has been removed.
Horn:
After 2 minutes the horn is reset regardless of the acknowledgement of an alarm.
Interface:
All internal errors are conveyed via the interface.
NOTE
By acknowledging the alarms via the interface there is no difference of "short acknowledge" and "long acknowledge".
After 0.1 s it will be "long acknowledged".
