Page 16: Filtron Controller Manual
Filtron 1- 10 controller user's manual List of features The “FILTRON 1-10” is a modular backflushing controller for automatic filters of 1 to 10 stations. There exist DC and AC models. The DC model can be powered either by 6v DC or 12v DC and it activates 2 wired 12v DC latching solenoids. - Page 17 How to program the controller The controller is equipped with an LCD display and 4 keys as displayed below. When the unit is left untouched for a minute the display is switched off and the only life signal is given by a beep sound that can be heard every 20 seconds.

- Page 19 OFF - no flushing will take place By time – In this case the flushing cycles will be repeated in a selected interval or will be triggered by the DP signal depending on what happens first. No matter how was the flushing cycle started the interval to the next cycle will start to be measured again after each ending of a flushing sequence.

The selectable delay steps are: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55 sec 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6 min the delay between stations –...
- Page 21 Handling Low pressure When a closed contact indication is received at the low pressure input of the controller, the symbol will start to appear blinking at the display. All activities will stop including the countdown to the next flushing cycle. If the low pressure happened while a flushing sequence was in progress, when the low pressure condition terminates the flushing sequence will start from the beginning rather than continue from the stop point.
