When a power failure occur
If the unit was deactivated in the middle of operation due to a power failure and is re-energized, the unit
automatically returns to the state just before the power failure and resumes operation. (To know the
setting method of this function, refer to page 28 "Power Failure Compensation Function".)
If the resumption of operation by automatic recovery is inconvenient, turn off the leakage breaker.
In the case if the error other than listed above occurred, turn off the POWER switch and primary
power source immediately. Contact the shop of your purchase or nearest Yamato Scientific
Service Office.
