Safe Machine Door Actuator (SMDA)

Machine Door Actuators for Safe Working Conditions

Automation with Integrated Safety for Horizontal Machine Doors

This system, which carries the name SMDA, is a complete end-to-end solution with a maintenance-free direct drive motor, a compact controller and intelligent operating software. The drive, which is based on proven technology for pedestrian passages, is fitted with a protective function which triggers an immediate change of direction if an obstacle is encountered. SMDA ensures that the force and permissible kinetic energy compliant with EN 12453 and EN 14120 are safely maintained.

Key Advantages:

  • Integrated safety: Safe force and speed limits for horizontal doors weighing up to 1,650 lbs (750 kg)
  • Drive is certified by TÜV (Performance Level d according to EN 13849-1)
  • Fast opening and closing times
  • Compact, space saving and maintenance free
  • Direct drive configurable with intelligent operating software

Overview

Typical areas of application:

Automating machine door operation can make your machines more efficient and easier to use, but they can also bear some risk. The system helps to minimize risk for operator and machine and prevent irreversible damage.

  • Machine tools (lathing, milling, grinding etc.)
  • Die casting machines
  • General production machines

Safely Automate Horizontal Machine Doors

The use of automatic door drives in modern machines has increased in recent years. The trend towards automating every possible machine function also includes opening and closing the doors of protective machine hoods. Loading and unloading machines represents a particular source of danger for both the operating personnel and expensive loading robots.

These protective machine door actuators include the technology for implementing a safe force and speed limit for horizontal doors with door weights up to 750 kg and more. This enables safe compliance with the approved forces without requiring additional safety elements such as light barriers or two-handed operation. The drive is fitted with a protective function which triggers an immediate change of direction to prevent irreversible damage if an obstacle is encountered.

The intelligent operating software – SMDTuner – assures efficient commissioning of the drive. Thanks to the integrated AutoTuning, there is virtually no need to perform settings during commissioning.  The system is powered by 115/230VAC, features galvanically isolated 24VDC I/O, and has an opto-isolated interface to the machine PLC.  The SMDA drives continue to offer valuable support for implementing safe and reliable automated protective doors.

Software

Quick and Easy Operating Software: SMDTuner

With the user-friendly SMDTuner operating software, commissioning the protective door the first time is quick and easy. This PC software is used to program the machine door actuator, start up the machine door actuator, query status values, and save the data so that data records already created can be archived for documentation purposes.

The software is easy to use and requires no special training. A wizard guides you through the sub menus in just a few steps. The software lets you individually optimize all SMDA drive types for various door configurations. This reduces costs during commissioning and maintenance.
