Page parameters 2/4:
1 : We choose if dP order is or isn’t taken into consideration to launch declogging cycle (reachable at level 1 and
above). « with dP » : declogging depends on dP order.
« without dP » : declogging does not depend on dP order.
2 : Threshold Maxi dP : if measure dP is above this threshold, more than one second, dP running order moves to
« ON » status (reachable at level 1 and above).
3 : Threshold Mini dP : if measure dP is below this threshold , more than one second, dP running order moves to
“OFF” status (reachable at level 1 and above).
Remark : if threshold Maxi dP=0 and threshold Mini dP=0, then the dP running order is forced on « ON » status.
4 : Threshold T2A : threshold corresponding to accelerated running (reachable at level 1 or above ).
If measure dP is above this threshold more than 5 seconds
→
accelerated running
→
T2 = T2A
If measure dP is below this threshold more than 5 seconds
→
normal running
Note : if threshold T2A is adjusted to 0, the function is not active (always in normal running).
5 : Threshold High Alarm dP (reachable at level 1 or above).
If measure dP is above this threshold more than 5 seconds
→
High Alarm dP
If measure dP is below this threshold more than 5 seconds
→
No High Alarm dP
Note : If threshold of High Alarm is adjusted to 0, the function is not active (no High Alarm dP generated)
6 : Threshold Low Alarm dP (reachable at level 1 or above).
If measure dP is below this threshold more than 5 seconds
→
Low Alarm dP
If measure dP is above this threshold more than 5 seconds
→
No Low Alarm dP
Note : If threshold of Low Alarm is adjusted to 0, the function is not active (no Low Alarm dP generated)
7 : Display of measure of instantaneous load loss dP.
8 : Adjustment to zero pressure (reachable at level 1 and above).
Allows to make a calibration at 0 pressure. Put the device out of pressure (disconnect the two pressure
connections) and press this area : zero pressure is calibrated.
9 : Display of current protection level.
10 : If press this area : go back to the former adjustments page.
11 : If press this area : go back to main page.
12 : If press this area : goes to the next adjustments page.
