Features
Controller created precisely for filter backflush 2, 4, 6 stations (on the 4 and 6 stations it is possible to control also the pressure sustaining valve)
Set interval between complete backflush cycles:
- in minutes (from 10 to 90 minutes,
10 by 10 minutes)
- in hours (from 2 to 24, 1 by 1 hours)
- it is possible to choose to have this interval
set by the differential pressure sensor
Set the backflush time per station:
- from 0 to 90 seconds (5 by 5 seconds)
- from 2 to 10 minutes (1 by 1 minutes)
Set the delay between 2 stations: from 0 to 90 seconds (5 by 5 seconds)
It is possible to set the delay for the reaction of the differential pressure sensor: from 5 to 90 seconds
Permanente memory
It is possible to set the duration of the impulse to the latching solenoids from 10 to 99 ms
Number of the cycles execute after last reset is showed on display
1 led (Alarm) signal if a short cut has happened or if the differential pressure sensor has been actived
Two digit display
Each one of 6 led (related to the 6 stations) flasheswhen the station is working
It may work with AC or DC power
