27
– Fault in condenser fan drive, replace the driver.
28
– Fault in condenser fan drive, replace the driver.
29
– Power board over temp – Heatsink cut-out temperature has been reached.
Check and correct:
- ambient temperature is too high - restore nominal conditions (Air-Cooled).
- obstruction in the fan driver cooling air flow.
- dirt or dust coating in the fan driver heat sink.
- excessive fan motor load.
- fan driver cooling fan failure
– replace the fan driver.
- electrical box cooling fan failure
– replace the electrical box cooling fan.
30 - Motor phase U missing
– Motor phase U is missing. Check the phase.
31
– Motor phase V missing – Motor phase V is missing. Check the phase.
32
– Motor phase W missing – Motor phase W is missing. Check the phase.
38
– Fault in condenser fan drive, replace the driver.
44
– Earth fault – Discharge from output phases to ground.
Check and correct ground fault on motor or motor-to-fan driver cables.
47
– Control Voltage Fault – 24 V DC may be overloaded. Check the fan driver 24 V DC
output cables.
51
– Fault in condenser fan drive, replace the driver.
52
– Fault in condenser fan drive, replace the driver.
63
– Fault in condenser fan drive, replace the driver.
80
– Fault in condenser fan drive, replace the driver.
Note
: “error 85” can appear trying to access a locked fan driver function pushing a display
button. This error isn’t related to a condenser fan drive malfunction.
Fault variable speed drive INV2 - Replace the variable speed drive.
4.
High Discharge Temperature
- The outlet temperature protection of the compressor has
triggered as a result of a very high temperature, over safety limits (probe T4)
– see the
specific point.
5.
Compressor protection
- The electrical protection of the compressor has tripped (see
QC1
– QC3 on the electric diagram) – reset, restart and check the perfect functioning of
the dryer. If RPP triggered
– power phases are not connected properly. Change two of
three phases at the supply main.
6.
Ice
: The temperature inside the exchanger (probe BT1) is too low
– the dew point is too
low
– see the specific point.
Note
: is the only alarm which is displayed and automatically resets with the dryer stopped
(STANDBY).
7.
Probe Fault LP
- Failure pressure transducer BLP - see electric diagram - check the
electric cabling and/or replace the transducer.
8.
Probe Fault HP
- Failure pressure transducer BHP - see electric diagram - check the
electric cabling and/or replace the transducer.
9.
Probe Fault T1
- Failure temperature probe BT1 - see electric diagram - check the
electric cabling and/or replace the probe.
10.
Probe Fault T4
- Failure temperature probe BT4 - see electric diagram - check the
electric cabling and/or replace the probe.
11.
Low Differential Pressure
- Low differential pressure between HP-LP values - see the
corresponding paragraph.
12.
High Evaporating Pressure
- The evaporating pressure is too high
– see the
corresponding paragraph.
13.
Low Condensing Pressure
- The condensing pressure is too low - see the
corresponding paragraph
1001.
Power Unit Communication Fault
- Data communication between display and
DMC50 power module is lost - Check the cable connection between two modules and / or
replace the cable.
1002.
Variable speed drive Communication Fault
- Data communication between DMC50
power module and compressor variable speed drive is lost.
Variable speed drive INV 1 not powered - check that the compressor contactor (KC1)
and/or circuit breaker (QC1) properly work/not triggered. Check proper variable speed
drive wiring.
Cable data connection broken - Check the cable connection between the two modules
and / or replace the cable.
DMC 50 power module failure
– Replace the power module.
Fault variable speed drive INV1 - Replace the variable speed drive.
