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(cè)裝置的配線。我想在這里的X傳感器和Y傳感器同時(shí)為ON的時(shí)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(huà),采用串聯(lián)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(shí),還有其它需要注意的地方嗎?
Cindy
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(duì)策,就必須在傳感器為OFF而非ON時(shí)發(fā)出信號(hào)的B接點(diǎn)處進(jìn)行配線。否則,如果使用A接點(diǎn),那么在傳感器損壞時(shí)也會(huì)發(fā)出信號(hào),引起安全問(wèn)題。
