7.2 MUTING
FUNCTION.
7.2.1 DESCRIPTION.
The muting function makes it possible to obtain a
“temporarily automatic
suspension”
of one or both light curtains in order to allow, for instance, the
objects passage without stopping the machine. As required by the standard, the
control unit has two inputs for the activation of this function. Two separate
muting functions are possible to use.
It is necessary to position and connect the muting sensors in order to avoid void
muting input condition. It is important to remember that the muting function
forces the system keep working and for this reason the muting functionality must
be designed and handled with care.
To use the muting function, it is mandatory to have the F39-A11 muting
lamp connected to the control unit, otherwise the control unit is locked.
7.2.2 INSTALLATION
CRITERIA
1
The muting sensors must recognise the material (pallets, vehicles,
etc.) over its full length.
2
The sensors must be arranged in such a way that the material is
recognised even when it is on a pallet or other transporting medium.
3
In case of different transport speeds through the muting area,
consideration must be used on the muting duration.
4
All the light curtains 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 muting
sensors.
