F
ault analysis
Cross-circuits and short-circuits of the OSSD1 and OSSD2 outputs are recognized
and le
ad to the locking state (lock-out). A malfunction with one of the K1 or K2
contactors is detected. The shut-down function is retained. In the event of manipu‐
lation (e.g., jamming) of the S1 pushbutton, the UE48-2OS 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) Connection of the 5-pin extension connection of the host device to the 5-pin system
connection of the guest device.
3) 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).
4) SELV/PELV safety extra-low voltage.

ask
Connection of two deTec4 Prime safety light curtains to a UE10-3OS safety relay.
Oper
ating mode: without restart interlock, with external device monitoring (EDM). If
required, the restart interlock is implemented via the machine controller.
•
Mode of oper
ation
If the protective field is clear and the UE10-3OS is in a fault-free de-energized
posit
ion, the system is enabled. Outputs OSSD1 and OSSD2 carry voltage, the
UE10-3OS is switched on. When the protective field is interrupted, the OSSD1 and
OSSD2 outputs switch the UE10-3OS off.
