information refer to the manual of the refrigerant compressor driver. To reset the alarm
conditions, switch off the dryer main switch (Control panel pos.1) wait at least 60 seconds,
and then restore the power.
If one or more alarms are active, the
compressor drive’s display will show active alarm
code number.
To reset the alarm, press the [Reset] button on the fan variable speed drive, the alarm LED
will switch off.
169001. Pwr.Card Temp - FC 101 fault number: 69
– The temperature sensor on the power
card exceeds the upper or lower limits.
Check and correct:
- Ambient temperature is too high or too low - restore nominal conditions.
- Obstruction in the compressor driver cooling air flow.
- Dirt or dust coating in the compressor driver heat sink.
- Excessive compressor load.
- Compressor driver cooling fan failure
– replace the compressor driver.
- Check electrical box filter cleaning.
-
Electrical box cooling fan failure
– replace the electrical box cooling fan.
169002. Earth Fault
– FC 101 fault number: 14 – Discharge from output phases to ground.
Check and correct ground fault on motor or motor-to-compressor driver cables
169004. Fault in compressor variable speed drive, replace the driver.
169005. Over Current
– FC 101 fault number: 13– Output current limit is exceeded.
Check and correct:
- Compressor cable or connections.
- Low input voltage to compressor driver.
-
Faulty compressor.
169008. Fault in compressor variable speed drive, replace the driver.
169009. Inverter overld. - FC 101 fault number: 9
– More than 100% load for a long time.
Check and correct:
- Excessive dryer thermal load
– restore nominal conditions.
- Compressor motor current adsorption is higher than nominal
– check proper
compressor motor functioning.
169010. DC under Volt - FC 101 fault number: 8
– Intermediate circuit voltage drops below
“voltage warning low” limit.
Check and correct:
- missing phase in input power supply.
- blown fuse.
- undervoltage on mains.
169011. DC over Volt - FC 101 fault number: 7
– Intermediate circuit voltage exceeds the
limit.
Check static or transient overvoltages in the input power supply. Restore it in the
proper operating limits.
169012. Short Circuit - FC 101 fault number: 16
– Short-circuit in motor or on motor
terminals/connections.
Check and correct short circuit on motor or motor-to-compressor driver cables.
169014. Mains ph. loss - FC 101 fault number: 4
– Missing phase on the supply side or too
high voltage imbalance.
Check the supply voltage.
169015. Fault in compressor variable speed drive, replace the driver.
169016. Fault in compressor variable speed drive, replace the driver.
169017. Fault in compressor variable speed drive, replace the driver.
169019. U phase Loss - FC 101 fault number: 30
– Motor phase U is missing. Check phase.
169020. V phase Loss - FC 101 fault number: 31
– Motor phase V is missing. Check phase.
169021. W phase Loss - FC 101 fault number: 32
– Motor phase W is missing. Check phase.
169023. 24 V supply low - FC 101 fault number: 47
– 24 V DC may be overloaded. Check the
compressor driver 24 V DC output cables.
169028. Earth fault - FC 101 fault number: 44
– Discharge from output phases to ground.
Check and correct ground fault on motor or motor-to-compressor driver cables.
169029. Fault in compressor variable speed drive, replace the driver.
169100. Fault in compressor variable speed drive, replace the driver.
169104. Fault in compressor variable speed drive, replace the driver.
169108. Fault in compressor variable speed drive, replace the driver.
169112. Fault in compressor variable speed drive, replace the driver.
169118. Fault in compressor variable speed drive, replace the driver
