SICK deTec4 Ex II 3GD - Connection Diagram: 5-Pin, T-Connector, UE48-2 OS, with Restart Interlock and External Device Monitoring (EDM)

Outputs OSSD1 and OSSD2 carry voltage, the UE10-3OS is switched on. When
t
he protective 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.

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) External device monitoring is only static.
3) SELV/PELV safety extra-low voltage.

T
ask
Connection of a deTec4 Ex II 3GD safety light curtain to a UE48-2OS safety relay.
Oper
ating mode: with restart interlock and external device monitoring (EDM). The
T-connector establishes a connection between the sender and the receiver.
•
Mode of oper
ation
When the protective field is clear, the OSSD1 and OSSD2 outputs carry voltage.
T
he system can be switched on when K1 and K2 are in a fault-free de-energized
position. The UE48-2OS is switched on by pressing S1 (pushbutton is pressed
and released). The outputs (contacts 13-14 and 23-24) switch the K1 and K2
contactors on. When the protective field is interrupted, the OSSD1 and OSSD2
outputs switch the UE48-2OS off. Contactors K1 and K2 are switched off.
