Outline: Communication/Power failure detected by the monitor microprocessor (IC2001) is stored on EEPROM, states can be confirmed in the
adjustment process mode.
Location: Page (1/20) of the adjustment process mode: MONITOR ERR CAUSE “0” if there is no error. It is cleared to 0 on the page (2/20) of the
adjustment process mode.
