1. Error
Code
Overload protection
2. Error
definition and error detection method
If the output current of "(Iac) >Imax (Arms)" or "THHS > 95°C [203°F] " is continuously detected for 10 minutes or more during
inverter operation.
3. Cause, check method and remedy
Refer to section - 6 - "Inverter" under part [4] "Trouble shooting principal parts" for error codes related to the
inverter.(page 172)
1. Error
Code
IPM error (Detail code 101)
2. Error
definition and error detection method
In the case of 4250
Overcurrent is detected by the overcurrent detection resistor (RSH) on the INV board.
In the case of 4255
IPM error signal is detected.
3. Cause, check method and remedy
In the case of 4250
In the case of 4255
Refer to section - 6 - "Inverter" under part [4] "Trouble shooting principal parts" for error codes related to the
inverter.(page 172)
4240
Cause
Check method and remedy
(1)
Air passage blockage
Check that the heat sink cooling air passage is not blocked
(2)
Power supply environment
Power supply voltage is 342 V or above.
(3)
Inverter failure
Refer to
X
[4] - 6 -.(page 172)
(4)
Compressor failure
Check that the compressor has not overheated during operation.
-> Check the refrigerant circuit (oil return section).
Refer to
X
[4] - 6 - (2)[2].(page 174)
4250
4255
Cause
Check method and remedy
(1)
Inverter output related
Refer to
X
[4] - 6 - (2) [1] - [4].(page 174)
Check the IGBT module resistance value of the INV board, if no
problems are found.
(Refer to the Trouble shooting for IGBT module)
Cause
Check method and remedy
(1)
Fan motor abnormality
Refer to
X
[4] - 6 - (2) [5].(page 175)
(2)
Fan board failure
Refer to
X
[4] - 6 - (2) [6].(page 175)
