4.12 Grouping of subsystems
In case of single-channel wiring of a safety capable output (Q1-Q4) to a signal input (EN), it
is possible to achieve category 4 in accordance with EN ISO 13 849-1 or SILCL3 in accord-
ance with EN 62 061.
Exclude cross-circuits by means of appropriate cabling!
• If several modules are used (> 1), cross-circuits on test pulse outputs (X1-Xn) can not
always be detected.
• If two modules are used (UE410-MU or UE410-GU and a UE410- XU), cross-circuits on
safety outputs (Q1-Q4) can not always be detected.
= If several modules are used, the possibility of cross-circuits has to be excluded by
means of appropriate cabling measures (protected installation, plastic-sheathed cable
etc.).
