6 Operating modes
6.1 Time-controlled cleaning (parameter E1, E5, D1)
Cleaning takes place continuously with the control times E1, E5 set.
Interval 2 (E3) becomes active only in the event of downtime.
6.2 Forced cleaning (parameter E8)
If cleaning is in the stopped state, a complete cycle with interval 2 is always cleaned after the set forced
cleaning time has elapsed. Forced cleaning is deactivated when the control is in stand-by or via an exter-
nal signal.
6.3 Differential pressure-controlled cleaning (parameter D5, D6, D1)
Cleaning starts when the filter’s differential pressure
∆
p
has reached the "
DP-Start
" value. The solenoid
valves are controlled sequentially. By cleaning the differential pressure drops after a certain period of time.
Cleaning stops when the differential pressure has reached the value “
DP-Start
” minus “
DP-Hyster.
”.
Interval 2 (E3) becomes active only in the event of downtime.
6.4 Downtime (parameter E9)
Downtime cleaning is started by the closing of contact connected to input E1. Downtime cleaning stops
when the contact opens.
Set the number of downtime cycles with parameter E9. Interval 2 is always valid during downtime.
6.5 Cleaning skip range (parameter EC)
See section "Parameter EC, cleaning skip range on page 28 on this.
6.6 Valve test mode
In the valve test mode, you can select an individual valve and operate it with the set control times (pulse
and interval time 1). If the interval time 1 is set to a value smaller than 5 s, the test program works with a
interval time of 5 s.
To activate the valve test mode select the parameter E0 and enter the code ABVT. The display shows a
window for valve 1 of the controller (I/O module RM-V6/X or RM-V8 / RM-V16) with address 1.

After expiration of interval time 1, the displayed valve is operated. Momentarily press the
key to select
different valves of the control 1 in succession. With each operation of the
key, the displayed valve is
immediately activated. Momentarily press the
key to select the remaining controls (I/O modules) in suc-
cession. You can stop the valve test mode by pressing the ENTER key.
