AF800 Tal-Gil Ft 1-10 DC Filter Controller and Solenoid
The "FILTRON 1-10" is a modular backflushing controller for automatic filters of 1 to 10 stations.
The DC model can be powered either by 6V DC or 12V DC and it activates 2 wired 12V DC latching solenoids. The voltage for the solenoids switching is boosted by a charge pump.
Flushing cycles may be triggered either by time or by he embedded electronic DP sensor reaching the set point, or by a dry contact signal from external DP sensor.
Endless looping problems can be eliminated by detecting repeated consecutive cycles passing beyond a predefined limit.
The unit can optionally handle a Pressure-Sustaining / Main valve, and Alarm output.
The unit is equipped with a customised LCD display and keyboard.
The unit counts separately the number of flushing cycles triggered by DP, by time and manually.
