Parameter block D0-D8 “Δp-controls“
Parameter D0 “Δp-controls“
Parameters D1-D8 can be faded in or out with parameter D0. Parameter D0 is factory-set to 1. The "Δp
control" is also active. It Δp control is not active, cleaning is set to the "continuous" mode.

Parameter D1 “Δp Cleaning mode“
The operating mode of the differential pressure-dependent cleaning can be set with parameter D1.

0 DP measure
The control only serves as differential pressure measuring device
with all Δp alarm switch points.
1
1 DP cont.clean.
Cleaning works continuously independent from the differential pres-
sure, with the parametrised control times (see parameters E1, E3,
E5 and E9). The Δp alarm switch points set are active.
2
2 DP stop clean.
The dedusting works in start-stop mode.
If the differential pressure reaches the start value set with parameter
D5 cleaning is activated until the differential pressure falls below the
value D5 - D6 (Δp start value minus Δp hysteresis value). The valve
number selected last is stored to enable cleaning to continue with the
subsequent valve when starting again.
3
3 DP cl.stop end
The dedusting works in the start-stop mode with circulation ending.
If the differential pressure reaches the start value set with parameter
D5, the valve number is stored and cleaning is activated until the dif-
ferential pressure falls below the value D5 - D6 (Δp start value minus
Δp hysteresis value) and the stored valve number is reached. (At
least 1 complete circulation is always carried out.)
4
4 DP-Stop end
Cleaning works in stop-end mode.
If the differential pressure reaches the Δp start value set by parame-
ter D5 cleaning remains active until the differential pressure drops
below the D5 - D6 (Δp start value minus Δp hysteresis value) and the
last valve has been operated.
Parameter D2 “Sensor source”
The source of the differential pressure measurement is set with parameter D2.
