2. Number of valve switch stages
Remote control valves and pilot
distributors are available in versions
with 2 to 8 stages.
The number of switch stages is set at this program step.
NOTE: Remote control valve manufacturers describe their products e.g. as 5-stage
valves with 4 switch settings, as at the settings “prime chemicals” two phases of
the process are distinguished: prime “chemicals with motive water” and “wash
slow” (only motive water flows).
Indicate the number of switch stages.
NOTE: Not selectable for “Valve 9000”, as the number of switch stages is set to 5
when this special valve is selected.
3. Pulse length
Where “pulse switching”, “external
switching “ or “SIATA” control was
selected at program step 1, the pulse
lengths of the individual pulses must
also be entered. Values between 1` and 999 seconds may be set.
4. Regeneration times
In this program step the appropriate
times required for the regeneration
phases of the switch stages entered at
program step 1 must be programmed in.
No times are entered for the service or standby phases.
Enter the switch stage and the required time within the range 1-999 minutes.
Example for number of switch stages = 4 :
Backwashing switch stage
1 : 10 minutes
Desalination switch stage
2 : 105 minutes
Washing out switch stage
3 : 15 minutes
5. Filter switching
Single filter 1
If you enter “Y” the system consists of 1 filter. The remote control valve is
connected to connector “CV1” and the service valve to “SV1”.
If program step 5.1 and 5.2 are programmed at “Y” the outputs “CV2” and “SV2”
are controlled parallel to the outputs “CV1” and “SV1”.
Single filter 2
If you enter “Y” the system consists of 1 filter. The remote control valve is
connected to connector “CV2” and the service valve to “SV2”.
The ability to select between “Filter1” and “Filter2” allows a two filter system to be
reset quickly to single filter service (for repair work or low water demand).
