TER-7 | Thermostat for monitoring temperature of the motor winding

• It monitors the 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 operator intervention (press RESET button).
• RESET of faulty state: a) button on the front panel b) by external contact (remote by two wires).
• The function of short-circuit or sensor disconnection monitoring, red LED flashing indicates a faulty sensor.
• Output contact: 2x switches / DPDT 8A / 250V AC1.
• State of exceeded motor temperature is indicated by the red LED
• 1-MODULE, DIN rail mounting.
• Terminals of the sensor are galvanically separated, they can be shorted out by terminal PE without damaging the device.
• in the case of the mains supply, the neutral conductor must be connected to terminal A2!
• Multivoltage supply AC/DC 24 - 240V.
