Function
92, 93
-
Burst disk (when HR mode is activated → heat recovery)
94, 95
-
Level control (refrigerant low liquid level)
* Special features for the digital inputs for control of the fans:
* When compressor combined control is activated, the fault output of the frequency converter is
monitored via the "compressor motor overload cutout" input of the
always
first compressor in the Z1
.
or Z2 circuit
For Z1, this means that the compressor 1 motor overload cutout contact is used for the monitoring of
the compressor 1 motor overload cutout
of the fault signal contact of the frequency converter for
and
Z1 (the contacts must be connected in series for this). For Z2, this means that, e.g. in the case of a
compressor configuration Z1 with compressors, the input of the compressor 5 motor overload
4
cutout (first compressor of the Z2 circuit) is used for the monitoring of the compressor 5 motor
overload cutout
of the fault signal contact of the frequency converter for Z2.
and
Wiring: Connect “FC fault” and “compressor motor overload cutout in series!
If the digital input
(terminals 80/81) is used for any safety-critical
fast unload external OFF
application, additional measures for the monitoring must be taken.
