The Safe Machine Door System (SMDS) is a flexible solution to support manual loading, robotic loading or other automation initiatives. The system offers switchable motion profiles supporting different types of automatic loading that may occur on the same machine. The SMDS Retrofit System is available in three sizes—small, medium, and large—for doors with opening widths up to 1,750 mm. It includes the door drive unit which contains all the mechanical components to operate a single or double-leafed door and can be easily installed within one shift.
No additional control cabinet is required, nor are additional safety elements required such as bumper bars or light curtains. After connecting the power supply (115-400 VAC) and control signals, the drive can be commissioned in approximately 15 minutes with the intuitive SMDTuner software.
Per EU machinery directive 2006/42/EC, every machine manufacturer is obligated to conduct a risk assessment for every machine. There is a crushing hazard on every machine with movable guards and special safety measures must be considered for machines that are operated by a person. Protective machine door actuators supplied by Dynatect include the technology for implementing a safe force and speed limit for horizontal doors with door weights up to 750 kg. The door actuator's protective function triggers an immediate change of direction if an obstacle is encountered, thereby preventing accidents and damages to material and tools.
The door actuator is certified by TÜV-SÜD and the maximum closing force and permissible kinetic energy are compliant with EN 14120 for automatic safety machine doors. This ensures safe and ergonomic operation by the personnel and compliance with EU machinery directive 2006/42/EC. Even with all these superior safety features, equipment productivity can be increased due to the short opening and closing times of the SMDS.
