Door Control Systems for Industrial Applications

The product-specific application/requirement lies in complying with the special industrial requirements concerning functional safety and door-closing mechanisms. Protective machine doors and power-operated doors and gates meet the EN 13849-1 safety standard (Safety of Machinery and Machinery Directive).

See the following PDF for an overview of automatic door controls for industrial applications.

Область применения



The machine tool door drive consists of a controller and a maintenance-free drive unit, the geared motors.

Controllers are electronic controllers connected to the power supply via an external power supply unit (SIDOOR NT40, SIDOOR Transformer). They are generally connected to the higher-level controller via digital or fieldbus interfaces, and can be configured via a user interface.

Three controllers are available for selection for machine tool doors:

• SIDOOR ATD400W, connected to the higher-level controller via the digital interface (relay-module), up to 400 kg door weight
• SIDOOR ATD410W, connected to the higher-level controller via a USS bus interface (USS module), up to 600 kg door weight
• SIDOOR ATD420W, connected to the higher-level controller via a PROFIBUS interface (PROFIBUS module), up to 600 kg door weight

The safe functions - force limitation, energy limitation and end position detection - fulfill the requirements according to EN ISO 13849-1:2008 for Category 2 and Performance Level d. The drives are suitable for power-operated guards according to EN 953:1997+A1:2009 Section 5.2.5.2 "Actuating forces".

Geared motors form the maintenance-free drive unit in the door drive. The geared motors are DC motors with non-self-locking gearing, and are speed-controlled. The set force and speed limits are not exceeded.

Operation of the named door drives does not require limit switches. The door width and the "OPEN"/"CLOSE" positions are determined automatically.

The power is transmitted by a toothed belt. The toothed belt passes over a deflector pulley and can be fitted with 2 door clutch holders. This enables it to drive both one-sided and centrally-opening doors. The accessories are not included in the scope of delivery, see "Accessories".
