the equipment during each maintenance
interval and other records regarding the
equipment will be recorded.
This signal from the controller
must be cancelled once the
maintenance work related to a
service
interval signal is
completed by pressing and
holding ESC and ▼ for 3
seconds. Cancelling this signal
also resets the maintenance
interval to a value of 2000.
Medium priority alarm conditions
The equipment is equipped to monitor and
signal compressor malfunctions. Such a
situation may occur for mechanical or
electrical reasons in any of the compressors.
This is frequently accompanied by an increase
in the current draw. This trips the thermal over
current protection in the FA device for the
respective air pump or air pumps (the blue
button is in position M and the yellow off
indicator is not pressed).
Such alarm is signalled by a flashing HA
beacon
–P1 and an the following message
appears on the display:
The beacon will continue to flash after the air
pump malfunction is remedied. Turn off the
alarm by pressing and holding
ESC and
▲together for 3 seconds.
The flashing beacon function and alarm may
be turned off during maintenance work by
pressing and holding
ESC
and ▲together for
3 seconds. Malfunctions are temporarily
indicated by a flashing display on the
controller and the subsequent message:
This message automatically disappears once
the malfunction on the air pump is remedied
and it is placed back into service. Alarm signals have priority over
maintenance interval signals.
As such, the light will indicate
an alarm from any of the air
pumps.
One the alarm is over, the
service interval is indicated by
the activated HA beacon.
17. SWITCHING OFF THE COMPRESSOR
Use circuit breakers FA13 and FA14 to switch
off the equipment for service or other reasons.
Vent the air tanks by disconnecting from the central compressed air circuit and opening the
outlet valve or the drain valves.
