Version: 1.1.0

3.5

Safe inputs

The safe input modules and corresponding clock outputs have a two-channel design. This has the
advantage that a two-channel safe sensor with an M12 connection can be used, and a fault such as cross-
circuit or external feed results in shutdown of the whole module.

DANGER

Clocked signals inside a sheathed cable

If clocked signals (clock outputs for the safe inputs) of different modules are used within a sheathed cable,
a fault of one module, such as cross-circuit or external feed, must lead to the switch-off of all of these mod-
ules. This is achieved by setting the

Module Fault Link active

parameter for all modules involved. This pa-

rameter is set to TRUE by default.

DANGER

Safe inputs in Cat.4 / PL e

If two safe input channels are to be used in a category 4 structure that are not on one M12 connector,
please make sure to combine always an even and an odd channel number.
