Safety Light Curtains

SAFETY LEVEL

Defines the self-monitoring and safety principles contained in the device; it must be chosen as a function of the risk level characterising the machine.

PROTECTED HEIGHT

This is the height protected by the light curtain. If it is positioned horizontally, this value shows the depth of the protected zone.

RANGE

This is the maximum working distance that may exist between the emitter and the receiver.

RESPONSE TIME

This is the time it takes for the safety light curtain to transmit the alarm signal from the time the protected zone is interrupted.

LIGHT CURTAIN RESOLUTION

The resolution of a light curtain is the minimum size of an object that, placed into the controlled area, will obscure the controlled zone and hence stop the hazardous movement of the machine.
