The SafeShield safety light curtain operates correctly as a protective
device only if the following conditions are met:
• The control of the machine must be electrical.
• The dangerous state of the machine must be transferable at any
time into a safe state.
• Sender and receiver unit must be so mounted that objects
penetrating the hazardous area are safely identified by the
SafeShield safety light curtain.
• The restart button must be located outside the hazardous area
such that it cannot be operated by a person working inside the
hazardous area. When operating the reset button, the operator
must have full view of the hazardous area.
• The statutory and local rules and regulations must be observed
when installing and using the device.
