Fault detected |
Operation of air compressor |
OFF | ON |
Compressor motor overcurrent or motor coil high temperature. |
Emergency shutdown. |
OFF | Blinking (1.2 sec./cycle) |
Discharge temperature higher than 110ºC(230ºF) or sensor short circuit. | |
OFF | High pitched blinking. (0,4 sec./cycle) |
