SICK deTec4 User Manual

•
Mode of opera
tion
If the protective field is clear and the RLY3-OSSD1 is in a fault-free, de-energized
posit
ion, the system is enabled. Outputs OSSD 1 and OSSD 2 carry voltage, the
RLY3-OSSD1 is switched on. The outputs (contacts 13-14 and 23-24) switch the
K1 and K2 contactors on. When the protective field is interrupted, the OSSD 1 and
OSSD 2 outputs switch the RLY3-OSSD1 off. Contactors K1 and K2 are switched
off. Status and fault information, as well as diagnostics data, can be transferred
directly to an IO-Link master via IO-Link connectors.
•
F
ault analysis
Cross-circuits and short-circuits of the OSSDs are recognized and lead to the
loc
king status (lock-out). A malfunction with one of the K1 or K2 contactors is
detected. The switch-off function is retained.

1) Output circuits: These contacts must be incorporated into the control such that the
d
angerous 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) To indicate the status on both sides, the MFP 1 connections from the sender and receiver
must be connected to each other in the control cabinet (optional).
3) SELV/PELV safety extra-low voltage.
