Filter cartridges
Running-in filter
The running-in of the filter cartridges is described in the supplementary
documents:
Running-in_instructions_cartridges_afterfilters-multicolor-en-V2

Filter cartridge cleaning
Parameters for filter cleaning:
– “1571 Filter cartridge ∆p Start filter cleaning”
– “1572 Filter cartridge ∆p Stop filter cleaning”
When new, the differential pressure “Filter cartridge ∆p” is approximately
0.6 kPa.
This value is automatically applied after running-in the filter. The value
can also be checked in t
he parameters “1571 Filter cartridge ∆p Start filter
cleaning” and “1572 Filter cartridge ∆p Stop filter cleaning”.
The cleaning cycle through all filter cartridges is started:
–
Hourly (system in coating mode) one complete pass as long as the
pressure is lower than the value of parameter 1571.
–
If the pressure rises above the value of parameter 1571, the filter
cleaning is continued cyclically until the last stored differential
pressure is reached again before the next cleaning cycle is
triggered.
–
If the last stored pressure is not reached after max. 4 complete
cleaning cycles, the last stored pressure is increased by 0.05 kPa.
The pressure values are continuously recorded in the log file
AfterFilterPressure.csv .
Filter cartridge aging
Due to the aging of the filter cartridges, the differential pressure of the
F
ilter cartridge Δp
and the differential pressure of the F
an Δp
increases.
Procedure for filter cartridge aging
Goal:
The after filter should always be operated with the operating point
differential pressure
F
an ∆p
.
Procedure:
As soon as the alarm 15071 Fan 1 minimum exhaust air appears, the
operating point must be readjusted by opening the throttle valve until the
display value on the CM40 display reaches the differential pressure
“Fan
∆p operating point”
.
