Troubleshooting and error codes

Check Item Diagnosis Result
1 OPERATION INDICATOR Check to see if the OPERATION indicator goes on and off when the main switch or breaker is turned on. (Check the primary and secondary voltage of the transformer.)
2 TERMINAL BLOCK Check the power supply voltage between ① and ② (Refer to the name plate.) (Check the primary and secondary voltage of the transformer.)
Check the fluctuating voltage between ② and ③ (15~60VDC)
3 FUSE (F01) 3.15A Check to see if the fuse blows out. (Check the R04 of the varistor.)
4 DC5V Check the voltage at the No.4 pin on CN13 connector of the infrared receiver. (Check the transformer and the power supply circuit of the rated voltage.)
5 DC12V Check the voltage at the white lead of the louver motor. (Check the transformer and the power supply circuit of the rated voltage.)
6 Check the voltage at the No.1 pin on CN10 connector and CN24. (Check the F01)
