Thermistor Connections (connections are shown in Figure 3-5).
This input is provided for over–temperature detection for motors that have
an internal thermistor. There is no polarity to the thermistor connections.
This provides “Basic” insulation only to the SELV control circuits and
assumes the motor has “Basic” insulation to the windings/mains circuits.
The thermistor type supported is PTC ‘Type A’ as defined in IEC 34–11 Part
2. The resistance thresholds are:
Rising temperature trip resistance: 1650 to 4000 ohms
Falling temperature trip reset resistance 750 to 1650 ohms
If the motor does not have an internal thermistor, you should disable the
thermistor trip function by:
