2) DP control choice:
Choose "AdP" or "SdP".
"AdP": for cycle controlled by the DP measurement.
"SdP": for cycle not controlled by the DP measurement.3) Maxi DP setting:
If the DP measurement exceeds this threshold for longer than one second, the DP order becomes « present »
4) Mini DP setting:
If the DP measurement goes below the DP threshold for longer than one second, the DP order becomes
« absent »
Note: If Maxi DP=Mini DP=000 then the DP order is mechanically controlled « present »
5) High DP Alarm Setting:
If the DP measurement goes above this threshold for longer than 5 seconds
high DP alarm.
If the DP measurement goes below this threshold for longer than 5 seconds
no high DP alarm
Note: if the high DP alarm is set at 000, it is inactive (no high alarm generated).
6) Low DP Alarm setting:
If the DP measurement goes below this threshold for longer than 5 seconds
low DP alarm.
If the DP measurement goes above this threshold for longer than 5 seconds
no low DP alarm.
Note: if the low DP alarm is set at 000, it is inactive (no low alarm generated).
7) Threshold for accelerated operation setting (T2A threshold):
If the DP measurement goes above this threshold for longer than 5 seconds
accelerated operation.
If the DP measurement goes below this threshold for longer than 5 seconds
normal operation
In accelerated operation, the T2 time is replaced by the T2A time.
Note: if this threshold is set at 000, the function is inactive (still in normal operation).
8) Cycle view:
If cleaning is in course, display of the time count in course (T2, T3 or T2A if it’s equipped with the DP)
with rapid flashing of the led of the menu opposite the corresponding time.
If there is a fault, display of the type of fault.
If manual running in course or fan stoppage cycles are in course, the led-menu opposite the fan/manu
flashes rapidly.
If accelerated cleaning is active, the led-menu opposite the T2A threshold flashes rapidly
If pressed, display of nxx with xx = EV will be actuated at the next blast.
9) Type of stop setting:
Choose "Fcy" or "Sto".
"Fcy": to stop at the end of the cycle.
"Sto": to stop cycle to the EV in course (stop on image).
10) Number of outputs setting
Number of paths/channels in the cleaning cycle
