and vice versa (T2=>S1). The AOPD response time to a
test request must be in a range of 2 to 18 ms. See
Example 3.
All available safety inputs must be occupied! In case
no components are connected, the remaining inputs
must be connected to the corresponding test signal using
bridges. In doing so, please note that the odd-numbered
test signal must be connected to the odd-numbered
safety input via the non-delaying bridge (T1 => S1) and
vice versa (T2 => S2). See Example 4.

• when cables are laid without protection, a failure detec-
tion time of up to 10 s is possible.
