CRITERIA FOR INSTALLATION
All the
muting
sensors must be connected correctly in order to prevent their
incorrect placement from causing undesired requests for
muting
.
1. The
muting
sensors must recognise the whole length of the material (i.e.
pallets, vehicles...).
2. The sensors must be arranged so that the material is also recognised if it
has to be lifted for processing.
3. The effect of various transportation speeds in the field of
muting
on the
overall duration of muting must be taken into account, if any.
4. All the safety photocells and
muting
sensors must be arranged so that
the previous material clears the last
muting
sensor before the new
material reaches the first sensors.
Example of installation of protection on a conveyor, which must allow a box to pass
through but not a person. The protection barrier
S
is connected to the control panel,
and
A1
,
A2
,
B1
and
B2
are temporarily excluded for the passage of the box via
sensors that enable
muting
. The contacts for these sensors are controlled on the
receiver unit.
Sensors
A
and
B
can be optical, mechanical, proximity sensors, etc., with closed
contact in the presence of the object to be detected.
