there is an AC contactor, blower, thermometer, temperature induction needle, two pass systemPlease help, a 380V plastic dryer control circuit, there is an AC contactor, blower, thermometer, temperature induction needle, two switching system. If the temperature reaches a certain temperature, the AC contactor automatically disconnects the power supply. When the temperature is low, the AC contactor is closed automatically.
Temperature induction needle, we also call thermocouple, put this thing in need of detection temperature place, connect thermometer, adjust the required temperature just fine. A lot of red machinery on plastic machinery
This is very simple, ah, according to the third floor of the answer on the line, as long as you set the temperature on the line
To achieve this control must have a temperature relay, as for the thermometer, only play a role in the display, the control does not work. I wonder if the temperature sensor is a temperature relayIn addition, please specify "two switches". Is there a start and a stop switch? Is it a switch or a button?
