8.3 Filter cleaning in Running mode
Perform filter cleaning in Running mode as follows:

Put the system into Standby mode by pressing the
Standby/Running button.

Activate the pilot signal by connecting terminals
X1:13 and X1:14 with a jumper. The unit goes in-

and pressure is established in the system.
3
Start the filter cleaning by pressing the filter
cleaning button.
The unit will now open and close the FCV 3 times and
then leave the FCV in its closed position. After the last
cleaning cycle, the unit returns to Running mode and
waits for the pilot signal to stop. It is possible to per-
form multiple filter cleaning cycles in Running mode.
When the pilot signal stops, the unit runs for 10
seconds (DIR time) and then opens the FCV and goes
into idling mode. The unit waits for a pilot signal for 12
minutes. If the pilot signal is not received during this
time, the unit will stop the motor and go into Standby
mode.
The idling time is set by the SSR timer and default is
12 minutes. DIR time is the delay after the pilot signal
has stopped before opening the FCV. The default is 10
seconds.
