Alarm Classes
The monitoring functions are divided into four alarm classes:
F0 Warning alarm
This alarm does not cause an interruption of the operation. An output is made without cen-
tralized alarm.
Æ Alarm text display
F1 Warning alarm
This alarm does not cause an interruption of the operation. Output of the centralized alarm.
Æ Alarm text + blinking LED "alarm" + relay centralized alarm (horn)
F2 Reacting alarm
This alarm causes a shutoff of the driving genset. Prior to opening the GCB, the active load
is first reduced, followed by a coasting.
Æ Alarm text + blinking LED "alarm" + relay centralized alarm (horn) + settle
F3 Reacting alarm
This alarm causes an immediate opening of the power circuit breaker as well as the shut-
down of the driving genset.
Æ Alarm text + blinking LED "alarm" + relay centralized alarm (horn)+ switching-off
NOTE
Via the activation of "Sprinkler operation" (terminal 6), alarm classes F2 and F3 are converted to alarm
class F1. (Exception: terminal 61 and overspeed).
ALARM CLASS F2 AND ALARM CLASS F3 → ALARM CLASS F1
