SICK deTem4 LT Muting A/P, Operating Instructions Manual

Page: 38 / 108

To use muting, the muting sensors attached to the muting arms must be connected to
the active unit.
The connecting cables of a muting sensor pair are connected to the muting signal A or
muting signal B connection of the active unit.

1) Output circuits: These contacts must be incorporated into the control such that the dan‐
gerous state is brought to an end if the output circuit is open. For categories 4 and 3, they
must be incorporated on dual-channels (x, y paths). Type 2 devices are suitable for use up
to PL c. Single-channel incorporation into the control (z path) is only possible with a single-
channel control and taking the risk analysis into account.
2) SELV/PELV safety extra-low voltage.

Task
Connection of a multiple light beam safety device deTem4 LT Muting A/P to a
RLY3-OSSD2 safety relay. Muting: entry/exit monitoring and C1 muting release
supplementary signal (photoelectric retro-reflective sensor dark switching). Operat‐
ing mode: with restart interlock and external device monitoring implemented on
the RLY3-OSSD2, and override on the deTem4 LT Muting A/P.
