If the power failure or undervoltage duration does not exceed the set value, the relay will automatically send a start signal after voltage recovery. If the interruption time exceeds the set value, automatic reset will not be triggered, and manual start is required to ensure equipment and personnel safety.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e• Switch-on Delay (t_{AN}): Supports continuously adjustable startup delay.
