Flooding alarm 2 Level monitoring in any tank by means of a float switch.
Exceeding the threshold outputs the fault message S.32
"Flooding 2".
This alarm can be delayed and temporarily suppressed.
Input
Define the input for the sensor: X12.9 / X12.11
The float switch must be an NO switch.
Max conductor cross section 1.5 mm² (see circuit diagram for
connections).
Alarm delay
0–999 min
This defines a waiting time in the event of false alarms as a
result of fluctuating water levels. The alarm is not sounded
until the sensor continues signalling after this time has ex-
pired.
Alarm mute
0–99 h
This suppresses the flooding alarm for the set time.
Before it can be suppressed, the alarm must first be acknowl-
edged (by the operator). After expiry of the suppression time,
the alarm is again sounded when the sensor continues sig-
nalling. The operator then has time to remedy the overflow
and yet is still alerted when the problem persists.
