The PTC Binary motor temperature sensing function is enabled when the Motor Temp Sensor Type
parameter is set to PTC Binary and the LTM R controller is connected to a binary positive temperature
coefficient thermistor embedded in the motor.

The LTM R controller monitors the state of the temperature sensing element and signals:
1) a motor temperature sensor warning when the measured resistance exceeds a fixed threshold.
2) a motor temperature sensor fault when the measured resistance exceeds the same fixed threshold.

The fault and warning conditions continue until measured resistance falls below a separate fixed motor
temperature sensor re-closing threshold.

Motor temperature sensing fault thresholds are factory pre-set and are not configurable. Fault monitoring
can be enabled or disabled

The resistance value is 2900 ohms and it is non-configurable
