WARNING!
Personnel injury due to unbraked drives!
The SBC safety function is bounded hard on the safe digital input STO1
(SDI00 and SDI01). So STO1 must be used coercively for all axes because
otherwise it can not ensured that currentless drives are always braked and
that they never drive against closed brakes.
Information
All other combinations on the DIP switch are invalid and lead at the latest
on demand of safety function (e.g. validating of safety function) to an error
message and the system changes into safe state.

Diagnosis via cross circuit test
To detect short circuits and cross circuits in the wiring of safe digital inputs
(terminal X26A) via DIP switch (S-ADR) a cross circuit test can be activated.
In this case the testoutputs of the D3-DP 3xx/x must be used or own testout-
puts which meet the signal format of the following table:
