External power should be cut off after the module is triggered. The module will then restore automatically for next use after reset. Reset
the module by following methods:
p
Suggestion: use the contactor self-locking mechanism, to realize module reset automatically. Wiring circuit diagram is as follows:
p
The contactor self-locking mechanism is not used: to avoid module damaging, do not keep the module triggered for long time(<4h),
cut off the power manually in time and use module again after 30s.
在模块保护功能被触发后，需要切断控制回路电源。重置后，模块将自动恢复以便下次使用。可通过以下方式进行重置：
p
推荐：利用接触器自锁机制，实现模块自动复位，接线电路图如下：
p
未使用接触器自锁机制: 为避免模块损坏，请勿长时间（小时）触发模块，及时手动切断电源，等待秒后可以再次投入使用。
