Alarm delay

With switch 5, the alarm delay is configured. By factory default the alarm delay is activated
(60 seconds). A fault or alarm is triggered only if the cause of the fault/alarm is present for
at least 60 seconds. The same applies to the switching off of fault or an alarm: they switch
off 60 seconds after the cause of the fault or alarm has been corrected. The alarm delay is
intended to prevent false alarms, which e.g. could occur by waves or splash water in the
separator. The alarm delay can be deactivated, e.g. for demonstration purposes. For nor-
mal operation, however, it is strongly recommended to have the alarm delay activated in
order to prevent false alarms.
4.2.6

Acknowledge button

With switch 6, the red acknowledge button is configured. By factory default the
acknowledge button is set enabled, so that the fault or alarm can be acknowledged by the
system operator. The button can be locked if an acknowledgement by the system operator
is not required. In this case, the unacknowledged state will persist until the cause of the
fault or alarm has been corrected.
4.2.7

Test button

With switch 7, the test button is configured. By factory default the yellow test button is set
enabled so that an alarm can be simulated and any connected external alarm transmitters
can be tested. If this test mode capability is not required for the system operator, it is pos-
sible to lock the button.
4.2.8

Alarm buzzer

With switch 8, the alarm buzzer is configured. By factory default the internal alarm buzzer
is set enabled so that an audible signal is given for faults and alarms. If an audible signal is
not required, it is possible to disable the buzzer.
