- Page 8 SEQUENCER CONTROLLER WITH OR WITHOUT DIFFERENTIAL PRESSURE MEASUREMENT - Fan stoppage operation: If the stoppage of the fan is detected, the cycle in course terminates and the defined number of cycles is carried out. Comment: if the re-start of the fan is detected during the execution of the parameterised number of cycles, a classic operation is started.
- Page 9 SEQUENCER CONTROLLER WITH OR WITHOUT DIFFERENTIAL PRESSURE MEASUREMENT - Operating of the sequencer: if the device is not equipped with the DP sensor: Conditions for the cleaning start-up: o input I1=1 (closed input) (representative of an external controller) If loss of the input I1, the sequencer executes the quantity of defined cycles when fan is off and stops. If the number of parameterised cycles is set at 0: the sequencer stops immediately or terminates the cycle in course according to the chosen stoppage mode.
