3.8.2 Signal description
Table 3-36: FB MUTING inputs
Name Permitted type Description
Enable TwinSAFE-In
FB-Out
Standard-In Muting can be activated via the Enable input. If the input is logic 0 an
interruption of the protective device results in immediate shutdown of
the FB output.
MutingIn1 TwinSAFE-In
FB-Out
The muting inputs are used to verify that they are operated in a
defined order.
1
st input channel. The parameterization is used to specify whether
the input has to be negated or is used directly.
MutingIn2 TwinSAFE-In
FB-Out
2 nd input channel, behaves like MutingIn1
If the discrepancy time is not equal 0, the 1 st and 2 nd input channel
are considered to be the 1 st input group and a discrepancy time
monitoring is carried out between both channels, if one of the two
input channels requests the safe state.
MutingIn3 TwinSAFE-In
FB-Out
3 rd input channel or 1 st input channel of the 2 nd input group, otherwise
corresponds with MutingIn1
MutingIn4 TwinSAFE-In
FB-Out
4 th input channel or 2 nd input channel of the 2 nd input group,
otherwise corresponds with MutingIn2
EDM1 TwinSAFE-In
FB-Out
Standard-In EDM1 is the feedback loop for the outlet channel (MuteOut), which is
switched off immediately. If this input as activated, the safe output
state is only exited when EDM1 is set to 1.
EDM2 TwinSAFE-In
FB-Out
Standard-In EDM2 is the feedback loop for the output channel (MuteDelOut),
which is switched off with a delay. If this input as activated, the safe
output state is only exited when EDM2 is set to 1.
OSSDIn1 TwinSAFE-In
FB-Out The protective device (AOPD - Active Opto-electronic Protection
Device), for example a light grid, is connected at the ‘OSSDIn’ inputs.
1 st input channel. The parameterization is used to specify whether
the input has to be negated or is used directly.
OSSDIn2 TwinSAFE-In
FB-Out OSSDIn2 is the 2 nd channel for the protective device and otherwise
matches OSSDIn1
