Emergency Off Connection, Single-Channel; Figure 17: Connection 8 × Emergency Off, Single-Channel, Short Circuit Test; Figure 18: Connection 8 × Emergency Off, Single-Channel, Short Circuit Test - WAGO 8FDI 24V PROFIsafe 750-662/000-004 Manual

Ensure protected installation when the short circuit test is activated!
With the two clock outputs T1 and T2, you can install the signal lines of at most
two contiguous input channels in one common cable. Otherwise, the F I/O
module cannot detect short circuits between signal lines of the inputs that are
tested with the same clock output. Make sure that the signal lines that belong to
the same clock output T1 or T2 are installed with protection against each other
according to IEC 60204-1 or ISO 13849-2 (e.g., as separate sheathed lines or in
separate cable ducts).
You can take alternative measures (e.g., antivalent evaluation) for fault detection
to achieve the required risk reduction for your application (e.g., SIL3/Cat.4/PL e).
The safety parameters of the F I/O module do not change.
