Error Codes
When an error has occurred, a red LED on the operation panel turns on and an error code
is displayed on the LED display. The panel does not turn to the display sleep mode while
the error code is shown.
Figure 14 Error Code example
After a component is replaced or the inspection is completed, turn the breaker on/off
several times 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 valve is highly likely.
