RUNNING:
Conditions to start declogging cycle:
-
Input I1=1 (input closed)
-
dP order ON (if cycle is dependent on load loss dP measure).
-
Compressed air presence:
- Input I2=1 (entrée fermée) if control by AON input A/C
- compressed air pressure A/C measure > operating threshold if control by by A/C measure
If compressed air is lost, the cycle stops at the end of the idle time. The cycle will resume when the
compressed air reappears at the solenoid valve where it was stopped.
If detection of fan stop by input I1:
- If the input I1 is lost (I1 = 0), fan stop is observed: the sequencer executes the number of cycles set and
stops. If the number of cycles is set to 0: the sequencer stops immediately or finishes the running cycle
according to the selected mode.
If detection of fan stop by load loss dP pressure measure:
- If the input I1 is lost (I1 = 0), the sequencer stops immediately or finishes the running cycle according to
the selected mode.
- If the fan stop is observed: the sequencer executes the number of cycles set and stops. If the number of
cycles is set to 0: the sequencer stops immediately or finishes the running cycle according to the selected
mode.
Note : when the device is switched on, a temporization of 10 seconds prohibits declogging cycle.
