Example for Logic and Wiring for Safety Circuit

The spindle interface X4 isn't wired, because the use is depending strongly on the
configuration of the spindle and the according its specific characteristic.

This interface in combination with an automatic spindle detection should be used only after
consultation with BMR.

By assigning the four address lines the spindle characteristic can be selected by an PLC or external
switches, in case it has been enabled
The digital wiring can even be achieved with outputs of logic circuits, with a High Out level > 20V.
