Low-alarm [mbar]
Threshold for the low alarm
message.
If the value falls below this
value, the relay contact is closed

the post-cleaning threshold
within the low-alarm delay.

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 re-
lay is closed for the parameter-
ised post-cleaning time.

Explosion hazard!
Before opening the housing, make sure that no explosive environmental
conditions, such as dust, exist.
The number of valves is valid for the entire system. The number of valves of each control
unit is set via the valve coding switch (s
ee chapter 6.3.1 Coding
switch). An interruption
alarm goes off, if less valves as indicated are connected.
