can be automatically ON.
To monitor an external device, a back check circuit (KA, KB) should be prepared between X1
and X3. If a back check circuit (KA, KB) is not required, the circuit between X1 and X3 should
be shorted.

put (white) of safety leak sensor is broken.
When this device is operated in auto reset, auto recovery of the system after
control output shutoff should be prevented with a safety relay unit.
