On safety
redundant design of the circuit in the safety eva-
luation device with self-monitoring; this allows the
safety sensor T4000 Multi to remain functional
even if a component fails,
external device monitoring.
Safety sensors are not allowed to be bypassed,
turned away, removed or made ineffective in any
other manner. Their contacts must not be bridged.
The diagnostic outputs 01, 02, 03 and 04 for the
doors must not be used as safety outputs.
To enter a dangerous state both safety outputs
must be connected and evaluated. This applies to
single-channel and dual-channel wiring. For
single-channel wiring, the safety outputs 13/14
and 23/24 must be connected in series. A cross-
circuit can result in a dangerous fault. To comply
with the safety requirements, this fault must be
prevented through constructive measures such as
appropriate cable laying (see Fig. 1 and Fig. 2,
„connection examples").
Damaged devices and components must be
replaced.
Liability is excluded in case of:
incorrect use,
failure to comply with the safety notes,
installation and electrical connection by
unauthorised personnel,
unauthorised modifications.
