7.3.2 INSTALLATION CRITERIA
1. The muting sensors must recognise the material (pallets, vehicles, etc.)
in all its length.
2. The sensors must be arranged in such a way that the material is
recognised even when it must be lifted for the relevant processing.
3. In case of different transport speeds in the muting area, always bear in
mind their influence on the muting total duration.
4. All the safety photocells and the muting sensors must be arranged in
such a way that the previous material has already passed the last
muting sensor before the new material has reached the first sensors.
In the previous page, an installation example of a protection arranged on a
conveyor is drawn; it must allow the passage of package 1, preventing
other packages from passing or it must allow the passage of packages 1
and 2, preventing package 3 from passing. The protection photocells
S
are connected to the F3SP-U5P-TGR control unit and are temporarily
interrupted at the package passage by means of the
muting A1 , A2 , B1
and B2 activated sensors.
Sensors A and B are optical, mechanical, proximity, etc. sensors with
closed contact in the presence of the object to be detected.
In both cases, the configuration
dip-switch 2 must be set in the on
position.
