NOTE
•
Oper
ating mode selector switches without test signals support between 2 and
8 operating modes; operating mode selector switches with test signals support
between 2 and 4 operating modes.
•
When wiring the tested operating mode selector switch, please remember that if
you are using a test output with an odd number (X1, X3, X5, X7), inputs with odd
numbers (I1, I3, I5, I7) must be used; if you are using a test output with an even
number (X2, X4, X6, X8), inputs with even numbers (I2, I4, I6, I8) must be used.

You will find more information in the operating instructions for the operating mode
selector switches.
5.4.1.8 Volt-free contacts
The configuration software provides a range of volt-free contacts for “free” arrangement
of cont
act elements. This enables a variety of N/C / N/O combinations to be imple‐
mented with and without testing. There are also start and stop button, reset button,
and external device monitoring (EDM) elements available.
