Single-channel
In case of a single-channel assignment, the outputs can parameterized in a
way that they operate independently from each other.
Parameterization
The safe outputs are parameterized in pairs per plug. For the parameteriza‐
tion options, refer to the following table:
Parameterization
Value range
Notes
Assignment
Not assigned
Assigned, both single-
channel
Assigned, both dual-
channel
The unassigned outputs are switch‐
ed off. However, the monitoring of
these outputs remains active.
The output assignment is specified in
the dual-channel operation.
Test pulses (output
disabled)
Disabled
Enabled
Switching on and off test pulses. For
these test pulses, the output drivers
in the switched-off state are switched
on (light pulses) for test purposes for
a short period.
Observe the notes below the table.
Switch-off delay for
stop category 1
Disabled
Enabled
Switched off (default values): No
switch-off delay
Enabled: The outputs switch off after
the set switch-off delay (250 ms,
500 ms, 1 s, 2 s, 4 s, 8 s, 16 s, 32 s,
64 s, 128 s).
Accuracy: ±5 % of the set value
Assignment of the
switch-off delay
Dual-channel
To channel 2
The switch-off delay can be assigned
either dual-channel or only to chan‐
nel 2.
The default values are highlighted in bold.
Tab. 6-1:
Parameterization per output pair
Test pulses
If the light pulses are switched off, cross-faults and short-circuits cannot be
detected when the output is switched off.
The parameterized outputs that are "not assigned", are still tested with test
pulses.

Behavior of the outputs if the switch-off delay for stop cate‐
gory 1 is switched on
The period until the outputs are really switched-off depends on the parame‐
terization of the switch-off delay and on the event causing the outputs to
switch off.
