CHART OF AN OPERATING CYCLE

Unclogging operates with the help of two digital negative pressure sensors.
— Two negative pressure sensors Dp1 and Dp2
Two operating modes may be selected:
— Unclogging without threshold:
— ON-LINE cycle when the fan is operating.
— OFF-LINE cycle when the fan is halted.
The (OFF-LINE) unclogging time depends on the number of cycles set in the Unclogging page
of the UI.
— Unclogging with threshold :
— ON-LINE unclogging cycle when the fan is operating, depending on a preset saturation
limit (800 Pa).
When the saturation limit is reached, the ON-LINE unclogging cycle starts.
The unclogging time always depends on the number of cycles set; however, when
the cycle is complete, if the head loss of the cartridges has not dropped below the
saturation limit, a new cycle starts.
