Is this the wiring diagram for the internal temperature of the exhaust fan motor?
Thread Content
This is a large exhaust fan; there are three stator temperatures and two transfer temperatures. Looking at the diagram, is this the correct wiring? I feel there’s a problem
How to add an image? ? ? ? No, there’s a link for it. Take a look at http://m.weibo.cn/2164294387/3973556398503134?sourceType=sms&from=1065095010&wm=9848_0009
For the shaft extension end and the non-shaft extension end, are two rotor temperatures measured?
Generally speaking, it is the connection method for PT100
There are two groups at the back; aren’t the terminals separated from each other?
Of course, otherwise how can we measure the motor temperature?
This is just the wiring diagram of a standard three-wire heating resistor inside the wiring box; there’s nothing special about it!
