Access protection by means of entry control

Access protection by means of entry control can be used when

the entry location to a machine or to a danger zone can be pre-

cisely defined and when no other unsecured access to this area

exists.

The laser scanner is preferably mounted above the entry point,

aligned vertically. To protect the protective devices, laser

scanners and fence from inadvertent adjustment and malicious

manipulation, the protective fields of the laser scanners must be

defined using reference contours. In this operating mode, the

scanner uses the sampled environment as a reference and can

therefore monitor changes to the structure of the protective

equipment as well as each individual measurement to detect an

entering person.

Securing danger zones by means of hand and arm guards

If a machine operator has to be close to the dangerous move-

ment or if the operator coordinates the positioning and removal

of workpieces at the machine, danger zone protection must be

implemented at the machine.

A protective device must be used to guard these danger zones.

The laser scanner is approved for securing danger zones by

means of hand and arm guards and can, also in combination

with protective field changeover, ensure flexible work safety. To

protect the protective devices, laser scanners and the screens

(attached to the sides as a reference and as additional access

protection) from inadvertent adjustment and malicious manipu-

lation, the protective fields of the laser scanners must be defined

using reference contours.
