  • Designed for elevators without cabin-door to increase the safety in the cabin during the travel
  • Easy mounting through the holes on the front of the profile

How It Functions

  • The "doors closed" signal is needed to make the controller start. (24.....220 VAC-VDC)
  • RELAY 1 is activated and controller can get a second "door closed" signal.
  • If there is no object between the barriers, RELAY 2 gets activated.
  • If there is an object in the 1-2 zone, the system get alarmed the RELAY 1-2 get deactivated but RELAY 3 gives an alarm signal.
  • If there is an object in the 3. Zone the system warns with a tone signal for 3 second, and if the object is still there the RELAY 1-2 gets deactivated, but a RELAY 3 gives an alarm signal.
  • For normal funtioning you have to reset the system.
