If the protective field is clear and the UE10-3OS is in a fault-free, de-energized
posit
ion, the system is enabled. Outputs OSSD 1 and OSSD 2 carry voltage, the
UE10-3OS is switched on. When the protective field is interrupted, the OSSD 1 and
OSSD 2 outputs switch the UE10-3OS off.

F
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 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.
