Upper threshold [mbar]
If exceeded, the Δp-
dependent cleaning
starts.
Start of the Δp cycle.
0…sensor max.
15.0
mbar
Lower threshold [mbar]
The
Δ
p-dependent
cleaning stops when the
temperature falls below
this value.
End of the
Δ
p-cycle.
OFF, 0.1…Sensor max.
10.0
mbar
Low - Alarm [mbar]
Threshold for the low
alarm message.
If the value falls below the
limit, the relay contact is
closed unless the post-
cleaning threshold is
undershot within the low
alarm delay.
OFF, -
5.0… Sensor
max.
OFF
Post-cleaning threshold [mbar]
The threshold is activated
when the lower threshold
is exceeded.
If the threshold is
activated and the
pressure falls below the
threshold, a post-cleaning
cycle is triggered and the
cleaning relay is closed
for the configured post-
cleaning time.
OFF,
0…Sensor max.

Δp-Offset [mbar]
The offset is added to the
currently measured
differential pressure.
