TER-7

• 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.
