fixed to OFF. Refer to "Chapter 5 Troubleshooting" to eliminate the cause of the error.
3-2 Interlock Function

3-2-1 Manual Reset
Even if detecting output of sensor is ON (without liquid leak), control outputs 1 / 2 (OSSD 1 / 2)
cannot be automatically ON.
A reset button and a back check circuit (KA, KB) should be prepared between X1 and X2 to
monitor an external device. If a back check circuit (KA, KB) is not required, only the reset button
should be prepared.
When the sensor is ON, it can be recovered with start-up of the external reset button.

Note: The reset will be canceled in case cleaning of sub detection part is not enough or detecting auxiliary out-
put (white) of safety leak sensor is broken.
