6.3 Timer function (Parameters 06, 07, 08)
In addition to the differential pressure dependent two-position control, the timer function also makes it
possible to carry out time-controlled forced cleaning. The timer works independently of other device func-
tions.
After the time configured under "Timer start" (Parameter 06) elapses, relay contact 12, 13 closes and
contact 11, 12 opens (see point

on page 5). After the time configured under "Timer period" (Parameter
08) elapses with the configured "Timer unit" (Parameter 07), relay contact 12, 13 opens and contact 11,
12 closes.
6.4 Self-monitoring
If all relay outputs are inactive (contacts 12, 13 / 15, 16 / 18, 19 are closed), then the RM-DPC Micro FP
differential pressure monitor is either
switched off or
defective.


Drain hoses. Clean joints be-
tween hose connections and
the filter casing with com-
pressed air (only towards the
filter, never towards the sen-
sor).
 Fit the hoses so there are no
kinks.
 Check the hose connections in
the device for water, kinks, etc.
