How the temperature sensor is used?

Connect the temperature sensor to the sensor socket.
Be aware of the polarity(+ and – of the sensor). If the temperature sensor isn’t connect with the sensor socket correctly, the error message is shown in the display, the bearing heater cannot start working in the temperature control mode.
The temperature sensor is equipped with a permanent magnet to secure the sensor to the inner ring during heating. Make sure the detection edge of the sensor is not damaged, dirt and dust. Mount the sensor so that the detection edge securely contacts the surface of the ring being heated. Don’t pull the lead for detaching the temperature sensor from Bearing. Be sure to remove it with holding the black sensor body. Pulling the lead causes a break. Don’t change or alter the extension lead wire of the thermocouple, or it may not measure correctly.
