17.3.1. Self Diagnosis Function (Three Digits Alphanumeric Code)

• When abnormality occur during operation, the system will stop operation, and OFF/ON control panel LED will blink and error

code will display on the control panel Timer display LCD.

• Even error code is reset by turning OFF power supply or by pressing ERROR RESET button, if the system abnormality is still un-

repaired, system will again stop operation, and OFF/ON control panel LED will again blink.

• The error code will store in IC memory.

•

To check the error code

1. When an abnormality occurs, system will stop operation and OFF/ON control panel LED will blink.
2. Error code of the abnormality will display on the control panel Timer display LCD.
3. To determine the abnormality description, the Error Code Table needs to be referred.

•

To display past/last error code

1. Turn ON power supply.
2. Press and hold the CHECK button for more than 5 seconds to enter status mode.
3. Press the SEARCH DOWN/UP button to retrieve past/last error code.
4. Press the CANCEL button or wait 30 seconds to exit status mode.
