Description

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.
