Active Alarm / Alarm History
The Alarm History screen contains the time of the alarm, the acknowledgment time and the
message corresponding to the alarm. The alarm message is a self-explanatory text that allows
quick troubleshooting of the equipment. The active alarm screen will only show alarms that are
currently on.
If an alarm locks the unit down, preventing it from running, the respective compressor/circuit will
be shown as alarmed/faulted. In those cases, press
“RESET ALARMS”
pushbutton. The equipment
will enter a check routine and try to re-start.
Two alarms require special treatment:
High pressure cut out alarm
It requires the operator/user to manually push the white button on
the face of the high pressure cut out switch located next to the
compressor. This is necessary because the device contains a latching
relay.
Compressor protection device
It requires the operator/user to access the “Compressor” screen and
touch the respective CPD OIL RESET button (1 or 2). When this is
done, the PLC opens up the circuit to the device using a relay,
interrupting its power for 7 seconds and resetting the latching relay.
