Translation of the original instructions MFS-E900, Filtration Group GmbH, 26.09.19, Mat. No. 72370026, Version 05
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 (B42 = time between
cleaning cycles)
B23 OFF = dP measurement with 2 sensors
ON = dP evaluation with external differential pressure
switch
B24 OFF = Without secondary filter
ON = With secondary filter
B25/B26 OFF/OFF
No drain valve, throttle flap
ON/OFF
Drain valve is time-controlled
OFF/ON
Drain valve coupled to motor
ON/ON
Drain valve coupled to cleaning
B27 ON = Continuous motor operation
The motor stops if a malfunction occurs or the release
signal is interrupted
B28 Not assigned
B37 dP signal present for too long
Determines when an alarm should be output. The "ready"
signal is simultaneously disabled.
B38 TH: Cleaning period
TL: Do not change
B42 Time until new time-controlled cleaning cycle. This time
starts again if a dP-controlled cleaning cycle takes place in
the meantime.
Only active in 'drain valve is time-controlled' mode.
B55
B25/B26 ON/OFF
TH: Drain valve pulse time
TL: Drain valve interval time
ON = Set value
OFF, CNT = Do not change
Only active in 'drain valve coupled to motor' mode.
B56
B25/B26 OFF/ON
Delay time until drain valve opens.
Only active in 'drain valve coupled to cleaning' mode.
B58
B25/B26/B24 ON/ON/OFF
TH: Period between end of cleaning and drain valve
opening
TL: Drain valve opening time
B58 Only active if a secondary filter is used.
B24 ON
TH: Time until secondary filter is pressurised
TL: Pressurisation period
B59 Counter for drain valve
Example: The value 2 means the valve is activated
by every second increase in differential pressure.
(B25 and B26 = OFF)
ON = Set value
OFF, CNT = Do not change
B63 Cleaning according to release counter
Number of times the release contact is closed
For sporadic applications where a dP increase is unlikely.
B64 Save cleaning request if no release signal present.
Cleaning as soon as release signal appears.
B65 Save cleaning request if a release signal present.
Cleaning cycle starts as soon as new release signal
appears.
Cleaning cycle always starts within 10 seconds of the
release signal appearing.
B66 Number of release cycles
ON = Set value
OFF, CNT = Do not change
B68 TH: Save cleaning release period in cleaning signal mode.
B77 Suppress differential pressure peaks
With throttle flap: Cleaning is delayed
