Troubleshooting of Handsome II
Step 1: Check the condition of the LED lamps and find out the cause of emergency shutdown by refering to the table below:
| RUNNING lamp | FAULT lamp | 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) | Sensor failure or poor connector contact. | |
| BLINKING | ON | Dryer failure. | Emergency shutdown unless the conditiuous operation is selected. |
Step 2: Eliminate the cause of the fault.
Step 3: Press the START button (green) to restart and the FAULT lamp will go out.
Caution:
- The dryer safety machanism is activated when the START and STOP buttons are pressed frequently.
- Keep 3 minute interval between stop and restart.
- Countermeasure for motor overcurrent/ motor coil high temperature.
Meter panel:
| LED lamps on the meter panel | Reset |
| Power Running Fault | Reset thermal relay |
- When excessive curent passed in the motor, the thermal switch trips and the compressor shuts down. Remove the cause of overcurrent and press the thermal relay reset (blue) button. The lamp will go out when the START button (green) is pressed to restart.
- Reduced cooling air volume for the motor may increase motor temperature, activating the motor protector and stopping the compressor. Eliminate the cause, i.e clogged dust filter or the like. Press the START button ( green) to restart, and the FAULT lamp will go out.
