The Configuration
Backflush valves will be allocated starting from output 1 and up.
The last backflush valve can be canceled and then its allocated output will be left
unused.
Three additional output devices can be included in the configuration: Alarm output,
Delay-Valve, and Main-Valve. Their location on the terminal board will be right after
the last backflush valve, first the Alarm output next the Delay valve, and then the Main
valve.
In order to enter into the configuration process press and hold down the ENTER key for at
least 3 seconds. The unit will detect how many “plug-in” boards (each of 2 outputs) are
used in the particular case. How the outputs will be allocated depends on the definitions
made during the configuration process described below. The following rules apply:
1.
2.
3.
Example:
Assuming there are 3 “plug-in” boards, this makes 6 outputs for use. If there are no Alarm-
output, no Delay-Valve and no Main-Valve, all the 6 outputs will be allocated for backflush
valves. If additionally a Main-Valve is defined, the first 5 outputs will be allocated for
backflush valves and output No 6 for the Main-Valve.
Output No 5 (of the last backflush valve) can be canceled and left unused. If additionally a
Delay-Valve is defined it will be allocated to output 5 right before the Main valve, leaving
the first 4 outputs for backflush valves, and once again output No 4 (of the last backflush
valve) can be canceled and left unused.
If additionally an Alarm-output is defined it will be allocated before the Delay-Valve
leaving only the first 3 outputs for backflush valves. No 3 can again be canceled.
