CAUTION
Safe function jeopardised by cross-faults
Improper installation may cause malfunctions due to cross-faults at the contacts
When test pulses are enabled, the Safety I/O-module will detect cross-faults be-
tween the inputs / outputs and other signal lines of the same module. Note that
you must prevent cross-faults with the security functions of other modules. You
should therefore protect the signal lines and/or lay them separately.
