2. System description

The Proximity Laser Scanner PLS continuously monitors the
contours of its surroundings with a scanning angle of 180°.
Two types of field can be programmed (warning fields and
protective fields), within which objects can activate the PLS
outputs.
Activation caused by objects in the protective field is carried
out safely, i.e. the circuit outputs are designed as 2 channels
(redundant) and monitor each other.
The PLS can be implemented as a personal protection unit in
stationary applications (monitoring of danger areas or access
to danger areas) as well as in mobile applications (collision
avoidance in vehicles).
The protective field must be dimensioned according to the
advice as laid down in the PLS technical description.
The diverse potential applications of the PLS can be expanded
still further by using the Laser Scanner Interface LSI. The LSI
allows quick and reliable switchover of protective and warning
fields in the PLS and the simultaneous use of several PLSs at
once. Further information about the LSI can be found in the
LSI technical description and the LSI operating instructions.
