Muting - Pilz PSEN op4F/H-A Series Operating Manual

OPERATING MANUAL
Long
Reduced
If long range is selected, the TX and RX can be installed at the maximum permitted operating
range. A reduced operating range is recommended for cases in which several pairs of light
curtains need to be assembled side by side and the coding function cannot be used.

7.7 Muting

The muting function guarantees that the safety function is automatically disabled over all or
part of the height of the detection zone, to enable specific, cyclical work operations to be
carried out without having to stop the machine operation.
In accordance with safety requirements, the light curtain is equipped with two inputs for
activating the muting function, MUTING1 and MUTING2.
The muting sensors must be able to detect the conveyed material (pallets, vehicles,...)
based on their length and speed. Where there are variable conveyor speeds within the
muting area, you must consider the effect this will have on the overall duration of the muting
process.
• The muting function excludes the light curtain during operation and maintains the
OSSD output switching elements in an activated state, based on the specific operating
requirements (Fig. 40).

muting sensors for muting in

• In accordance with the applicable standards, the safety light curtain has two inputs
(MUTING1 and MUTING2) to activate this function.
• This function is particularly suitable for cases in which an object, but not a person,
needs to pass through the danger zone under certain conditions.
