the K1 and K2 contactors on. When the protective field is interrupted, the OSSD1
and O
SSD2 outputs switch the RLY3-OSSD2 off. Lamp H1 lights up. Contactors K1
and K2 are switched off. As soon as the protective field is clear again, lamp H2
flashes.

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. In the event of manipulation (e.g.,
jamming) of the S1 pushbutton, the RLY3-OSSD2 will not re-enable the output
current circuits.

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). 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 to a UE10-3OS safety relay.
Oper
ating mode: with restart interlock, external device monitoring (EDM), and
application diagnostic output.

Mode of oper
ation
If the protective field is clear and the UE10-3OS is in a fault-free de-energized
posit
ion, the field indicator and the H2 lamp flash. The system can be switched
on. The system is enabled by pressing S1 (pushbutton is pressed and released).
