RUNNING :
Conditions to start declogging cycle :
-
Input I1=1 (input closed)
-
Running order dP ON (if cycle is dependent on load loss measure dP).
If detection of fan stop, by input I1 :
-
If we lose the input I1 (I1=0), fan stop is observed : the sequencer executes the defined number of cycles
and stops. If the defined number of cycles is at 0 : the sequencer stops immediately or finishes the running
cycle, according to the choosen mode.
If detection of fan stop, by load loss measure dP :
-
If we lose the input I1 (I1=0), the sequencer stops immediately or finishes the running cycle, according to
the choosen mode.
-
If detection of fan stop : the sequencer executes the defined number of cycles and stops. If the defined
number of cycles is at 0 : the sequencer stops immediately or finishes the running cycle, according to the
choosen mode.
Note : when the device is switched on, a temporization of 10 seconds prohibits declogging cycle.
