Error Code [5110]

1. Error code definition
Heatsink temperature sensor (THHS) fault (Detail code 01)
2. Error definition and error detection method
When a short or an open of THHS is detected just before or during the inverter operation.
3. Cause, check method and remedy
Cause
(1) INV board failure
For inverter-related error codes, refer to the following page(s). [8-9 Troubleshooting Inverter Problems](page 264)
HWE14040
Cause
Short detection
70°C [158°F] and above (0.4kΩ)
110°C [230°F] and above (0.4kΩ)
240°C [464°F] and above (0.57kΩ)
70°C [158°F] and above (0.4kΩ)
70°C [158°F] and above (1.14kΩ)
110°C [230°F] and above (0.4kΩ)
160°C [320°F] and above (0.18kΩ)
160°C [320°F] and above (0.18kΩ)
If the problem recurs when the unit is put into operation, replace the INV board.
Check method and remedy
Check thermistor resistance.
Check for pinched lead wire.
Check for wire coating.
Check connector.
Check for wire.
Check the intake temperature of the sensor with the LED
monitor.
When the temperature is far different from the actual temper-
ature, replace the control board.
