15: If there is a fault: this red symbol "attention" is flashing
16: If a fault is present: pressing on this area resets the displayed fault.
17: If a fault is present: pressing on this area resets all faults.
18: If presence of a fault: display of the type of fault (see paragraph defaults)
Load loss dP page:
This page is accessible from the main page by pressing the "measure of the load loss dP" area.
1: Graph of the measure of the load loss dP.
Display of the last 430 operating points of the device (1 new point is added according to the value of the set
step). When the power is turned off, the graphic is reset.
2: Setting the graph advance (1 to 255 seconds).
Each time this timer expires, a new point is added to the graph. The value of the added point is the average
measured over this time (see note 1).
3: Display of measured values of the minimum and maximum pressure load loss dP observed.
Notes: the minimum value is observed two minutes after the detection of the fan operation.
The maximum value is not observed between the start of a declogging shot and three seconds
after that shot.
4: reachable only with level 2.
Pressing on this area resets the minimum and maximum values of the observed load loss dp pressure.
Note: the maxi is initialized to the value 0. This value will be updated with the first maximum observed.
the mini is initialized to the value 999. This value will be updated with the first minium observed.
5: If press on this area: return to the main page.
6: Display of the instantaneous load loss dP measure.
7: Display of current protection level.
note1: examples:
if set to 1 second: recording length 1s x 430pts = approx. 7 min.
if set to 90 seconds: recording length 90s x 430pts = 645mn = about 10 h
if set to 180 seconds or 1 pt every 3 minutes: record length 3 x 430pts = 1290mn = about 21 h
