When not using remote sensing, short-circuit terminals +V and +S, and also terminals -V and -S.
The overvoltage protection function will operate, so turn OFF the input power and then turn it back ON again.
The internal control circuit has malfunctioned, thereby activating the overvoltage protection function.Turn OFF the input power and then turn it back ON again. If the problem reoccurs, the internal circuits are possibly damaged. Consult your OMRON representative.
