9.1 Motor sensors
9.1.1 Temperature sensor
A working temperature sensor mounted inside the motor should give a
resistance reading of approximately 550 ohms at 20 °C.
The temperature sensor mounted on the outside gives a resistance
reading of approximately 670 ohms at 20 °C.
Retrofitting of external temperature sensor
1. The temperature sensor can be mounted to the right or left of the
terminal block, depending on which side is easiest to access and
the length of the cable from the new sensor.
2. Scrape the surface clean where the new temperature sensor is to
be mounted.
3. Place the temperature sensor as shown in the illustration.
