SIDOOR AT40 BASIC application-optimized controller for elevator door systems. Delivery release was issued on March 9, 2018.

  • Entry
  • Associated product(s)
The SIDOOR AT40 BASIC controller in the ELEVATORS portfolio segment is the logical expansion of the SIDOOR AT40 RELAY and SIDOOR AT40 CAN controllers for price-sensitive applications which are already established on the market.

Since the internal modules (relay module and terminal module) are not required in many customer applications, the ELEVATORS segment of the SIDOOR product range is being expanded to include this controller with basic functionality.

Technical description

The unique functions of the SIDOOR product family, such as the comprehensive learn run function with determination of the  moved mass of the door, have been implemented in the SIDOOR AT40 BASIC controller, too. The learn run function can be launched at the press of a button and is self-explanatory.

The SIDOOR AT40 BASIC controller offers the following  technical functions, which, of course, are compatible with the SIDOOR AT40 RELAY controller:

  • Connection of the SIDOOR M2, M3, M4 and M5 DC motors for door systems of up to 600 kg movable mass and max. 8 kg counterweight.

  • Connection of the SIDOOR NT40 and TRANSFORMER power supply units.

  • Connection of the SOFTWARE KIT and SERVICE TOOL supplementary devices.

  • Automatic commissioning via learn run button, including determination of the movable mass of the door and limitation of forces and energies.

  • Door travel without limit switches

  • Ambient temperature in operation -20 °C to +50 °C

  • Storage temperature -40 °C to +50 °C

  • 4 digital inputs, 10-28 V DC with 9-27 mA

  • 24 V DC output voltage with max. 400 mA

  • Opening width of door from  300 mm  to 5000 mm

  • EMC Directive 2014/30/EU, EN 12015, EN 12016

  • Standards for safety EN 60950-1/EN 81-20

  • W*H*D  = 320 mm x 60 mm x 80 mm
