Test 4 – Inverter and PFC temperature sensor
Symptom: Fault code 0-40 appears in the operator screen.
Remove power and allow the system to reach room temperature (at least 60 minutes after use).
If the system has a temperature interlock, either fault code 0-40 or fault code 0-99 appears on the operator screen.
Display the service screen and check the “F” field for the live (most recent) fault code. Fault code 0-40 appears on the
operator screen, but you need to identify the specific 0-40 fault code variation:
• 0-40-0 PFC module under temperature.
• 0-40-1 PFC module over temperature.
• 0-40-2 Inverter module under temperature.
• 0-40-3 Inverter module over temperature.
If fault code 0-99 appears on the operator screen, display the service screen and check the “F” field for:
• 2-10-0 Inverter module temperature sensor open.
• 2-10-1 Inverter module temperature sensor shorted.
• 3-11-0 PFC module temperature sensor open.
• 3-11-1 PFC module temperature sensor shorted.
