Connecting the temperature sensor
Requirements
● Motor with temperature switch (e.g. Thermoclick) or thermistor (e.g. PTC type A)
● Parameterization required
1. Connect the temperature sensor:
Temperature switch at terminals T1-T2 Thermistor at terminals T1-T2
2. Parameterize the temperature sensor.
You will find more information on parameterizing the temperature sensor in Chapter
Thermistor motor protection with temperature sensor (Page 112).
The 3RW55 soft starter monitors the motor for excessive temperature. If the temperature is
exceeded, a warning is generated or the motor is switched off depending upon the
parameterization. Restarting takes place after a reset.
