DIFFERENTIAL PRESSURE SWITCH

11) T1 setting:
Activation time of an output (in 1/100th of second).12) T2 Setting:
Rest time between two outputs (in seconds).
13) T2A Setting: (if presence of the DP measurement sensor)
Accelerated rest time between two outputs (in seconds).
14) T3 Setting:
Rest time between two cycles (in minutes).
0: inactive.
15) Setting T4:
Maximum non-cleaning time (in hours).
0: inactive.
If the sequencer has not performed any cycle for the set number of hours, the cycle in course terminates
(if stopped on image) and a cleaning cycle is performed (the cycle remains controlled by the output I2 (a/c) ).
Comment: the T4 time is initialised at each impulse on an EV.
16) Number of fan stoppage cycles setting:
Define the number of cycles to be carried out at the time of detection of the fan stoppage
0: inactive.
17) Manual running:
The cycle in course terminates and the number of set cycles is carried out without taking account of the
DP order or the input controls I1 and I3.
- Fan stop running:
If the stop of the fan is detected, the cycle in course terminates and the number of cycles parameterised 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.
- The carrying out of the cycles when the fan is stopped remains controlled by the input I2 (a/c)
The fan stop can be detected in 2 ways (set in the factory): through loss of the input I3 or, if it’s equipped with the
DP, through the disappearance of pressure (as soon as it becomes lower than a value variable from 5 to 20 daPa).
If there is a DP sensor present, the choice of the type of detection of the stop fan is indicated in the
“HIDDEN MENU”.
