Explanation of the term "protective devices"

Rewinder RW500
Adjustable guards are used:
• where due to the use of different downstream devices, the protective
device needs to be adjusted for the current situation.
• They can be set manually by the operator easily and without tools.
• They have electric locking (safety switch).
When the protective device is opened, this causes the machine to stop.
The machine can be restarted only after the protective device is closed.
Protective devices differ from the guards in that they do not form a physical
barrier between the endangered person and the danger spot.
Protective devices include:
• Two-hand switches
• Sensitive protective devices such as:
Contact mats, safety strips, switch rods and switch wires.
• Optoelectronic, protective devices such as:
Light barriers, laser scanners and camera-controlled safety systems.
