3022 !! Inverter fault !! Temp.Sensor Cool.2 IF>TmpSens.Cool.2 low Fault in temperature sensor for dissipator 2. Thermistor –B2 to input of
PCB Signals –A13- X52:1-2 has a short or a disconnection.
Recheck sensor B2, replace it if necessary.
3023 !! Inverter fault !! Temp.Sensor Cool.3 IF>TmpSens.Cool.3 low Fault at temperature sensor for dissipator 3. Thermistor –B3 to input of
PCB Signals –A13- X53:1-2 has a short or a disconnection.
Recheck sensor B3, replace it if necessary.
3024 !! Inverter fault !! Temp.Sensor Cool.4 IF>TmpSens.Cool.4 low Fault at temperature sensor for dissipator 4. Thermistor –B4 to input of
PCB Signals –A13- X54:1-2 has a short or a disconnection.
Recheck sensor B4, replace it if necessary.
3025 !! Inverter fault !! Temp.Sensor Cool.5 IF>TmpSens.Cool.5 low Fault at temperature sensor for dissipator 5. Thermistor –B5 to input of
PCB Signals –A13- X55:1-2 has a short or a disconnection.
Recheck sensor B5, replace it if necessary.
3026 !! Inverter fault !! TempSensorRectifier IF>TmpSens.Rectif low Fault at temperature sensor for the dissipator at the rectifier am rectifier
(top). Thermistor –B6 to input at PCB Signals –A13-X56:1-2 has a short or
a disconnection. Check sensor B6, replace it if necessary.
3027 !! Inverter fault !! TempSensorCabinet IF>TmpSens.Cabin. low Fault at temperature sensor for inverter interior. Thermistor –B7 to input of
PCB Signals –A13-X57:1-2 has a short or a disconnection.
Check sensor B7, replace it if necessary.
3028 !! Inverter fault !! Current control IF>CurrentControl - PCB Current control defective. Replace the current control PCBs. Replace
the 60-pole flat cable conductors between current control and PCB Control
electronics. Contact our service station.
3029 !! Inverter fault !! ResistOutpFilter IF>R-outpFilter mean The temperature of the resistor of the output filter is too high. Clean the air
filter; recheck the fans of the device. Recheck the temp.contact –
at PCB Signals –A13-X81:9: 24V=good, 0V=fault. Cool down the operation
environment; measure the length of the motor conductors, note the type of
the motor conductors and contact our service station. Maybe the motor
conductors are too long for the installed filter.
3030 !! Inverter fault !! IntermCircFuse IF>IC-fusing high The fuses for the intermediate circuit (ultra-quick action fuses) have
tripped. Recheck the monitoring contact of F41/42: input at PCB Signals
-A13-X81:10: 24V=good, 0V=fault. Take out the fuses and check with the
ohmmeter whether the fuses have really tripped. After that contact our
service station.
3031 !! Inverter fault !! InputReactor 1 IF>InpReactor 1 low/ mean The temperature of the input reactor L8 (L8.1) is too high. Clean the air
filter; recheck the fans of the device. Recheck the temp.contact of the
reactor: input at PCB Signals –A13-X81:16: 24V=good, 0V=fault.
Cool down the operation environment.
