3.2 A battery of screen or gravel media filters with a Main Valve:
Starting the flushing cycle:
The same as in “A single TAF filter” above.
The flushing cycle:
The Main Valve solenoid is switched on and closes the battery’s Main Valve. The controller counts down the
“Delay Main Valve Close” parameter
( see screen number 8 ). O
nce this count reaches zero the process moves to the
next stage.
Solenoid valve number 1 is switched on, the flushing of the first filter of the battery starts and the controller
starts to count down the Flushing Time parameter
( see screen number 5 ).
Once this parameter is counted down to
zero the solenoid of the first filter is switched off and the process moves to the next stage.
The controller counts down the “Between Filters Delay” parameter
( see screen number 5 )
and once this count
reaches zero the controller switches on the solenoid of the second filter of the battery and starts to count down
again the Flushing Time parameter. Once the flushing process of the second filter is finished the controller
counts again the delay between filters and starts the flushing of the next filter. This process continues till the last
filter is flushed and its solenoid is switched off, then the process moves to the next stage.
The controller counts down the “Delay Main Valve Open” parameter
( see screen number 8 ).
Once this count reaches
zero the Main Valve solenoid is switched off causing the Main Valve to reopen and the flushing cycle ends.
