Error Codes
When an error occurs, a red LED on the timer setting panel turns on and an error code is
displayed on the LED display. The panel does not return to the display sleep mode while the
error code is shown.
After a component is replaced or the inspection is completed, turn the breaker on/off several
times for at least 60-120 seconds each time, to confirm the error does not re-occur.
Below is the list of the error codes. If the corrective action does not solve the error problem, a
malfunction of the PCB controller is highly likely.
