I'm considering how to do the wiring for the new detection system. When this sensor X and this sensor Y are both turned on I want it to make the system stop, but how do you think I should wire it?: 我在研究新檢測裝置的配線。我想在這里的X傳感器和Y傳感器同時為ON的時候讓裝置停止，該怎么配線呢？

If that's what you are doing, a series wiring would work. By the way, what is the purpose of putting in these sensors?: 那樣的話，采用串聯配線就可以了。
你安裝這些傳感器的目的是什么呢？

I'm putting them in to ensure safety. Is there anything else I should be careful of when I do the wiring?: 是為了確保安全才安裝的。
在配線時，還有其它需要注意的地方嗎？

If you are using them as a safety device, Normal Close should be used for the wiring so that a signal is sent when the sensor is off, not on. Otherwise, if the sensor is broken there is a chance that a signal might be sent from Normal Open and cause a safety problem.: 如果是作為安全對策，就必須在傳感器為OFF而非ON時發出信號的B接點處進行配線。否則，如果使用A接點，那么在傳感器損壞時也會發出信號，引起安全問題。
