MUTING
INSTRUCTION MANUAL

MUTING
The Muting feature allows the automatic deactivation of the safety status on the whole
(Total Muting) or part (Partial Muting) of the safety area. This feature is particularly suit-
able when an object, but not a person, has to pass through the dangerous area. This
allow
s carrying out definite cyclical operations without blocking a working machine.
The Muting feature excludes the ESPE during its functioning, but it maintains the OSSD
ou
tputs active (according to particular operating requirements). To activate the Muting
feature, the safety laser scanner is equipped with two inputs, Muting 1 and Muting 2
(according to the current Standards).
The Muting sensors must be placed according to the material’s length and speed to be
able t
o recognize the passing materials (pallets, vehicles, etc.). If a muting area has dif-
ferent speeds, it is necessary to evaluate their effect on the total muting duration.
It is important to remember that the Muting feature represents a forced condition of
the
system and therefore has to be used with the necessary precautions.
If Muting 1 and Muting 2 inputs are activated by two Muting sensors or actuators, these
should
be correctly connected and placed to avoid undesired Muting or potentially dan-
gerous conditions for the operator.
NOTE
NOTE
NOTE
Muting 1 and Muting 2 cannot be activated simultaneously. Muting status is
signaled by an external Muting Lamp that may be connected to the safety
laser scanner and the display of the user interface. When the Muting func-
tion is ON, the lamp blinks and the display shows “MUTING”. The lamp
must be always placed in a visible location.
The Muting zone can be different for each Zone Set configured on each
device.
Up to two Muting zones can be configured in a Safety Area.
WARNING
Carefully select the configuration, because a wrong one can cause the
incorrect functioning of the Muting feature and a reduction of the safety
level. To correctly use the Muting feature, please refer to the relevant ref-
erence standard.
WARNING
The Muting sensors must be placed so that during the activation of the
Muting feature it is not possible for a person to pass through the desired
zone.
