ELKO EP TER-7 Thermostat For Monitoring Temperature

ELKO EP TER-7 Thermostat For Monitoring Temperature controls temperature of motor winding with PTC thermistor in-built in motor winding or an external PTC sensor. This thermostat features “Memory” function, when temperature overrun (and output switches off) the output is hold in faulty stage until service hit. Terminals of sensor are galvanically separated, and can be shorted out by terminal PE without damaging the device. The TER-7 thermostat offer "control of sensor fault" function which controls interruption or disconnection of sensor. This device offers fixed levels of switching, DIN rail EN 60715 mounting, and IP40 from front panel/IP20 terminals protection degree. The TER-7 thermostat is available in 90mm x 17.6mm x 64mm (3.5″ x 0.7″ x 2.5″) dimensions and 1-MODULE housing.

Features

  • 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:
    • Button on the front panel
    • 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
  • In case device is supplied from network, neutral wire must be connected to terminal A2
