Figure 24: Connection diagram: 8-pin UE10-3OS safety relay
1) Output circuits. These contacts must be incorporated into the control such that the dan‐
g
erous 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/protective extra-low voltage.

ask
Connection of a deTec4 Ex safety light curtain to a UE10-3OS safety relay. Operat‐
in
g 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 posi‐
t
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). Outputs
OSSD1 and OSSD2 carry voltage, the UE10-3OS is switched on. When the protec‐
tive field is interrupted, the OSSD1 and OSSD2 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. Manipulation (e.g., jamming) of the S1 pushbutton prevents
the output circuits from being enabled.
