Glossary
4. Glossary
4.1. Filtersystem Skizze
Glossary
Valve sequence
A valve offset of 2 causes: valve 1, valve 3, valve 5 ... are
triggered
Chamber sequence
A chamber offset of 1 causes:
chamber 1, chamber 2, chamber 3 .... are cleaned. A
chamber offset has higher priority than a valve offset. A
chamber offset of 0 causes:
all valves acc. to valce sequence in chamber 1 are pulsed.
Then chamber 2 etc...
Operating mode
- Permanent
Permanent processing of the parameterised valve se-
quence. Controller via start / stop signals.
- dP Threshold
Control of the cleaning process via the dP signal. Cleaning
starts during exceeding of the parameterised upper thresh-
old; stops when dropping below the lower threshold.
- dP Controller
dP signal and air flow signal Influence the cleaning process.
The breaks are controlled and regulated in dependence
with the filter characteristics to be set via the supporting
points.
Online cleaning
The dampers for pure gas and raw gas stay open during
the cleaning.
Offline cleaning
During the cleaning of a chamber the selected dampers of a
chamber are Off. Within the chamber the valve sequence is
applied. After the cleaning the chamber sequence is con-
sidered.
Semi Compartment
Offline Cleaning
SCOC
‘Half-Chamber Offline Cleaning’. Requires two pure gas
dampers per chamber. By that way one half of the chamber
can be cleaned offline, while the other half remains in the
filter process.
Post cleaning
Post cleaning may be required if the complete filter has
been taken out of the procedure.The post cleaning com-
prises of the complete filter and performs the parameterised
amount of cycles / valves etc. The post cleaning uses ‘cyc-
letime 2’.
Background cleaning
The background cleaning becomes active if no ‘regular’
cleaning is performed for a parameterisable time. This is
often the case in small air flows or low dust inputs.
The differential pressure is reviewed regarding a minimum
value at the same time. If the reading falls short it is as-
sumed that no fan operation exists and the cleaning is
discontinued.

Glossary
Partial cycle
Cleaning runs as long as the required start condition is
present. If the start condition is missing, the cleaning will be
interrupted. The cleaning then will be resumed at interrupti-
on point.
Complete cycle
If the required start condition is set, a cleaning cycle via all
active valves is performed.
Forced cleaning
Independently of other necessary conditions (e.g. dP-
thresholds) the setting of this condition starts the cleaning
process. Cleaning runs as long as the condition is set, resp.
in cleaning cycle until all active valves are cleaned.
In connection with the operating mode partial cycle the
valves can be individually processed.
Drain valves
The control supports the drain valves at the local manifold.
Parameters 4.14 to 4.16.
