4.7.5 Muting restart
Following a muting fault (e.g. muting timeout, failure of the supply voltage), the restart button can be used
to override the muting path even if the protective field is interrupted see chapter 8.6.2 „Muting restart“.
4.7.6 Alternative connection for second muting signal
Particularly in cases in which the second independent muting signal comes, for example, from a control,
it is advantageous to connect this signal to the machine interface (8-pin plug). In operating modes 2, 3, 4
and 6, the second muting signal can alternatively be connected to input MS2 of the 8-pin plug or to input
MS2 of the local interface (5-pin socket).
