Compressed air A/C parameters page:
Two cases are possible depending if the device has or not a sensor for the measurement of compressed air:
-
If the device does not have the sensor for A / C compressed air measurement, the compressed air can only
be controlled via the I2 AON input.
-
If the device has the sensor for A / C compressed air measurement, the compressed air can be controlled
with the measurement or with the I2 AON input.
1: Choice of compressed air control mode (reachable at level 1 or above):
"A/C measure": the control is done with compressed air measure A/C
"A/C input": the control is done with the state of the AON input A/C (I2)
2: Choice of the control or not of the presence of compressed air out of declogging cycle (reachable at level 1 or
above)
If control by A/C measure: check OK if measure> low alarm threshold
If control by A/C input: check OK if input A/C (I2) present (=1).
3: Time for the control of the compressed air out of declogging cycle.
Adjustable from 1 to 255 seconds (reachable at level 1 or above).
If there is no presence of compressed air for more than this time and if out of cycle control validated: generation
of a general compressed air fault. Indication of the fault in the main page: "A/C FAULT".
This fault is auto reset when the control returns to OK.
