Load loss dP parameters page:
1: choic
e if dP order is or isn’t taken into consideration to launch declogging cycle (reachable at level1 and above).
« with dP » : the declogging is dependent on the dP order.
« without dP » : the declogging in not dependent on the dP order.
2: threshold Maxi dP : if measure dP is above this threshold, more than one second, the dP 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, the dP order moves to
“OFF”
status (reachable at level 1 and above).
Note: if threshold Maxi dP=0 and threshold Mini dP=0, then the dP 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).
Note: An accelerated running request can also be given with the AON I3 input.
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 instantaneous measure of load loss dP.
8: Adjustment to zero pressure (reachable at level 1 and above).
Allows making a calibration at 0 pressure. Put the device out of pressure (disconnect the two pressure
connections) and press on this area : zero pressure is calibrated.
9: Display of current protection level.
10: if press on this area: go back to parameters menu page.
11: if press on this area: go back to main page.
12: If press on this area: jump to the 4-20mA dP output parameter page (if available function).
