Fig. 13: “Interval” potentiometer
The controller determines the required interval time from
the current differential pressure and the selected
characteristic.
The interval time is shorter if the differential pressure
increases and longer if it is reduced.
The change in the interval time is non-linear.
The cleaning process ends if the differential
pressure falls below approximately 5% of the
measuring range.
9.1.2 Switching threshold
If “switching threshold” mode is selected, the controller is
activated when the set threshold is exceeded.
Factory settings:
•
Terminal 16-17 not assigned
•
Terminal 18-19 jumpered
•
Jumper 3 down
Full cycle (optional)
•
XS1 jumper T/G Cycle switch up
A full cycle is executed if the switching threshold is
exceeded.
Fig. 14: Jumper settings for full cycle
Partial cycle (optional):
•
XS1 jumper T/G Cycle switch down
A cleaning process is executed if the switching threshold
is exceeded.
The cleaning process ends if the differential pressure
falls below the switching threshold.
The next valve is activated when the controller is
activated again.

9.1.3 Time control
Factory settings:
•
Terminals 16-17 and 18-19 jumpered
•
Both pressure measuring lines disconnected
•
XS1 jumper Schw./Reg. switch down
Fig. 16: Jumper settings for time control
A time-controlled cleaning process starts if contacts 16-17
and 18-19 are closed.
