4: Choice of the control or not of the consumption of compressed air during a declogging pulse (reachable at level
1 or above)
The consumption control is done during the shooting and during the idle time between two shots.
If control by A/C measurement: check OK if measure<operating threshold or if the measurement has dropped
more than the set drop value.
If control by A/C AON input: check OK if A/C input (I2) becomes absent (goes to 0).
If three successive checks have failed when activating a solenoid valve: a fault is generated with indication of
the fault in the main page: "NO CONS.A/C Svx" (where x is the number of the faulty SV).
This fault is auto reset when the control returns to OK.
5: Choice of the control or not of the reinflation of the tank after a declogging pulse (reachable at level 1 or
above)
The reinflation control is done during the idle time between two shots
If control by A/C measure: check OK if measure> operating threshold.
If control by A/C AON input: check OK if input A/C (I2) present (= 1).
If, at the end of the idle time, the control is not OK: a fault is generated with indication of the fault in the main
page: "INFLAT.A/C Svx "(where x is the number of the faulty SV).
This fault is auto reset when the control returns to OK.
6: Operating threshold: adjustable from 0.0 to 6.0 Bar (reachable at level 1 or above).
If control by A/C measure:
- used to control consumption and reinflation.
- the declogging is performed if the measure is above than this threshold.
Note: if the operating threshold is 0.0, the control is not performed.
7: drop pressure value: adjustable from 0.0 to 1.0 Bar (reachable at level 1 or above).
If control by A/C measure:
- used for consumption control.
Note: If the drop is set to 0.0, the control is not performed.
8: Low alarm threshold: adjustable from 0.0 to 6.0 Bar (reachable at level 1 or above).
If control by A/C measure:
- used for out of declogging cycle control.
Note: If the low alarm threshold is set to 0.0, the control is not performed.
9: Display of instantaneous measure of compressed air.
10: 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 compressed air
pressure connection) and press on this area: zero pressure is calibrated.
11: Display of current protection level.
12: if press on this area: go back to parameters menu page.
13: if press on this area: go back to main page.
14: If press on this area: jump to the 4-20mA A/C output parameter page (if available function).
