- It monitors motor coil temperature.
- Fixed levels of switching.
- PTC sensor is used for sensing, it is in-built in motor winding by its manufacturer or there is used an external PTC sensor.
- MEMORY function – relay is blocked in an error state until until operator intervention (press RESET button).
- RESET of faulty state:
a) Button on the front panel.
b) By external contact (remote by two wires). - Terminals of sensor are galvanically separated, they can be shorted out by terminal PE without damaging the device.
