Important information

DANGER

Hazard due to lack of effectiveness of the protective device
Persons and parts of the body to be protected may not be recognized in case of non-
observance.

b

Make sure that the following design requirements are met so that the multiple
light beam safety device can fulfill its protective function.

°

The active and passive units must be arranged such that persons or parts of
the body are safely detected when they enter the hazardous area.

°

Reaching under, over, and around as well as moving the multiple light beam
safety device must be prevented.

°

Check whether additional safety measures (e.g. restart interlock) are neces‐
sary when it is possible for people to be located between the protective
device and the hazardous point without being detected.

DANGER

Hazard due to lack of effectiveness of the protective device
Certain types of light radiation can influence the protective device, e.g., light radiation
from fluorescent lamps with electronic ballast installed in the path of the beam, or
beams from laser pointers directed at the active unit.

b

If this type of light radiation is present in the environment of the protective device,
take additional measures to ensure that the protective device does not become
dangerous.

4.3.1

Scanning range and beam separation

Beam separation and number of beams

The beam separation is the distance between two adjacent light beams, measured
from the center of one beam to the center of the next.

Scanning range

The scanning range is the maximum dimension of the light path between active and
passive units.

4.3.2

Minimum distance from the hazardous point

A minimum distance must be maintained between the multiple light beam safety
device and the hazardous point. This distance is required to prevent a person or part of
the body from reaching the hazardous area before the dangerous state of the machine
state has completed.
