OPERATION
NP-DK50-Nx2VTM-AD-EN-6_04-2022 38 04/2022
Low priority alarm conditions
The equipment is equipped to monitor and
signal maintenance intervals. Maintenance
intervals are whole number multiples of 2000
operating hours I = n x 2000 hours (n = 1, 2,
3, etc.). The maintenance of specific
components pursuant to the attached Table 2
must be performed once a maintenance
interval is passed. This condition is indicated
by an activated yellow HA beacon and an
information message on the display.
Maintenance intervals are
counted from the moment the
equipment is first started up.
This table must be inserted into the
compressor maintenance log along with Table
3 in which maintenance work, inspections of
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.
