Question:
The MRV5-T system work abnormally.The 6E error code display on wired controller and 110-0 error code display on the double 8 digital tube
Answer:
1,The compressors1 didn't work, but the compressor2 work normally.Check the bus side voltage of INV1 baord is about 516V DC,the current is 0.
Then we exchange INV1 and INV2 baord.During startup phase, the bus side voltage is about 523V,but the current is about 0.4V. After for a while, the compressor stop, the 111-1 error code was displayed. So we have judged that the compressor is broken.After replacing the INV board, the unit work normally.
