5.2.4.7.4 Muting Enable
The “Muting Enable” function is intended to provide added safety for the user when working with muting. If
the function is activated during parametrization, the “Muting Enable” input is evaluated. The muting can now
be enabled or blocked using the external Muting Enable signal.
If the Muting Enable input is active, muting is initiated with a valid muting sequence. If the Muting Enable
input is inactive, the muting function is blocked and can not be initiated.

“Muting Enable” signal may only become
inactive if muting becomes active. From
this point, the input is no longer taken into
account during the active muting cycle.

NOTE!
If the “Muting Enable” function is activated in the parametrization, the
“Muting Enable” input must be active at the latest by the start of a valid muting sequence.
