NOTE
MUTING
Muting function allows automatic deactivation of the safety function on the whole or
part of protected height in order to carry out definite cyclical operations without block-
ing machine work.
As the pertaining safety requirements demand, ESPE is equipped with two Muting acti-
vation inputs, MUTING1 and MUTING2.
The Muting sensors must be able to recognize the passing material (pallets, vehicles, …)
according to material's length and speed.
In case of different transport speeds in the Muting area, it is necessary to consider their
effect on the total Muting duration.
• The Muting function excludes the light curtain during functioning, maintaining
active the OSSDs outputs, according to particular operating requirements (see fig-
ures below).
• The safety light curtain is equipped with two inputs (MUTING1 and MUTING2) for
the activation of this function, according to the current Standards.
• This function is particularly suitable when an object, but not a person, has to pass
through the dangerous area, under certain conditions.
• It is important to remember that the Muting function represents a forced condi-
tion of the system and therefore has to be used with the necessary precautions.
