in service warning
condition (status
area orange
colour) - See
section
10.15.5
Status area blinking orange : one or more service warnings are active. The display shows
the ID code and the description of the active warning.
Status area steady orange : one or more service warnings need to be reset. The display
shows the ID code and the description of warning which is no longer active but which still
need to be reset
Service warnings are shown by following codes and descriptions :
15.
Low Dew Point
- Dew point too low
– see the corresponding paragraph.
16.
High Dew Point
- Dew point too high (higher than adjusted value on HdA parameter)
–
see the corresponding paragraph.
17.
Probe Fault T2
- Failure temperature probe BT2 - see electric diagram - check the
electric cabling and/or replace the probe.
18.
Probe Fault T3
- Failure temperature probe BT3 - see electric diagram - check the
electric cabling and/or replace the probe.
19.
Drainer
- The condensate drain ELD (and/or ELD2 if installed) does not work properly
(ALARM contact is open)
– see electric diagram and corresponding paragraph.
20.
Programmed service
- Maintenance notification time is expired (over than adjusted
value on SrV parameter)
– carry out the scheduled maintenance and reset the hour
meter.
21.
High discharge temperature
- The outlet temperature protection of the compressor has
triggered as a result of a very high temperature but within safety limits (probe T4)
– see
the corresponding paragraph.
22.
High Evaporating Pressure
- The evaporating pressure is too high
– see the
corresponding paragraph.
23.
Low Condensing Pressure
- The condensing pressure is too low - see the
corresponding paragraph.
24.
High Condensing Pressure
- The condensing pressure is too high - see the
corresponding paragraph.

Variable speed drive INV1 in warning condition
– For complete
information refer to the manual of the refrigerant compressor driver.
Compressor
variable speed drive warning disappear when abnormal condition is removed.
169201. Pwr.Card Temp - FC 101 fault number: 69
– The temperature sensor on the power
card exceeds the upper or lower limits. See alarm “169001”
169204. Fault in compressor variable speed drive, replace the driver.
169205. Over Current - FC 101 fault number: 13
– Compressor variable speed drive peak
current limit is exceeded. See alarm “169005”.
169208. Fault in compressor variable speed drive, replace the driver.
169209. Inverter overld. - FC 101 fault number: 9
– More than 100% load for a long time. See
alarm “169009”.
169210. DC under Volt - FC 101 fault number: 8
– Intermediate circuit voltage drops below
voltage warning low limit. See alarm “169010”.
169211. DC over Volt. - FC 101 fault number: 7 - Intermediate circuit voltage exceeds the
limit. See alarm”169011”.
169214. Mains ph. loss - FC 101 fault number: 4
– Missing phase on the supply side or too
high voltage imbalance. See alarm “169014”.
169216
.
Fault in compressor variable speed drive, replace the driver.
169223. 24 V Supply Low - FC 101 fault number: 47
– 24 V DC supply may be overloaded.
See alarm “169023”.
169225. Current Limit - FC 101 fault number: 59
– The current exceeds the peak value.
Check and correct:
- Compressor cable or connections
- Low input voltage to compressor driver
169226. Low temp. - FC 101 fault number: 66
– Heat sink temperature too low.
Restore nominal conditions.
169308. Fault in compressor variable speed drive, replace the driver.
169315
.
Fault in compressor variable speed drive, replace the driver.
.
169318. Fans Warning - FC 101 fault number: 24
– Fault in compressor variable speed drive,
replace the driver.
