ault analysis
Cross-circuits and short-circuits of the OSSDs are recognized and lead to the lock‐
in
g state (lock-out). The malfunction of the UE10-3OS is detected. The shut-down
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 two 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 Com1 connections from the sender and receiver
must be connected to each other in the control cabinet (optional).
3) SELV/PELV safety extra-low voltage.

Connection of a deTec4 Ex II 3GD safety light curtain with an SP1 system plug to a
R
LY3-OSSD1 safety relay. Operating mode: without restart interlock, with external
device monitoring. IO-Link: data output via IO-Link connector.

Mode of oper
ation
If the protective field is clear and the RLY3-OSSD1 is in a fault-free, de-energized
posit
ion, the system is enabled. Outputs OSSD1 and OSSD2 carry voltage, the
RLY3-OSSD1 is switched on. The outputs (contacts 13–14 and 23–24) switch the
