Parameter Description
B20/B21 OFF/OFF
Pressure sensor 0 to 16 bar, 0 to 10 V
ON/OFF
Pressure sensor -1 to 15 bar, 0 to 10 V
OFF/ON
Pressure sensor 0 to 40 bar, 0 to 10 V
ON/ON
Pressure sensor 0 to 10 bar, 4 to 20 mA
B22 OFF = No time-controlled cleaning
ON = Time-controlled cleaning, see also
B42
B23 OFF = Analogue delta P measurement
with 2 sensors
ON = Digital delta P measurement with
external differential pressure switch
B24 OFF = Without secondary filter
ON = With secondary filter
Drain valve
operating
mode
B25=OFF No drain valve
B26=OFF Throttle flap
B25=ON Drain valve is time-controlled
B26=OFF
B25=OFF Drain valve coupled to motor
B26=ON
B25=ON Drain valve coupled to cleaning
B26=ON
B27 Not assigned
B28 Not assigned
B37 Delta P signal present for too long.
This parameter determines when an
alarm should be output to indicate
incomplete cleaning. The "ready" signal is
simultaneously disabled.
B38 Cleaning period
B39 Interrogation time of secondary filter.
Used if B24 = ON. If the pressure in the
secondary filter does not fall below a
defined value following the cleaning cycle,
"secondary filter dirty" is indicated.
Indication only, no switch-off.
B42 Interval time for time-controlled cleaning.
Only relevant if B22 = ON.
B52 Counter for number of cleaning cycles.
B55 Drain valve pulse and interval times in
'drain valve is time-controlled' mode.
B25 = ON; B26 = OFF
ON = Set value
OFF, CNT = Do not change
B58 Drain valve coupled to cleaning.
TH = Period between end of cleaning and
drain valve opening.
TL = Drain valve opening time.
B25 = ON; B26 = ON
B63 OFF =
ON = Cleaning according to release
counter.
The counter counts the number of times
the release contact is closed. If B63 = ON,
a cleaning cycle starts when the number
of release cycles is reached.
Recommended for sporadic applications
where a delta P increase is unlikely.
Translation of the original instructions MFS-E900, Filtration Group GmbH, 26.09.19, Mat. No. 72370026, Version 05
B64 ON = Save cleaning request if no release
signal present.
The cleaning cycle starts as soon as the
release signal appears.
B65 ON = Save cleaning request.
The cleaning cycle starts as soon as a
new release signal appears.
This causes the cleaning cycle to always
start within 10 seconds of the release
signal appearing.
B66 Counter for number of release cycles.
Recommended for sporadic applications
where a delta P increase is unlikely.
ON = Set value
OFF, CNT = Do not change
B68 Save cleaning release period in cleaning
signal mode.
B65 = ON.
B77 Suppress differential pressure
If B25 and B26 = OFF
B77 = Cleaning delayed until throttle flap
closes.
If an electric ball valve is used as the

backflush or drain valve, a power failure
could result in serious problems.
There is a risk that the filter could run dry.
