Functional example of control inputs:
The wiring of the control inputs is also shown in chapter 4.3 .
The picture on the right hand side shows the function
and the two wiring principles of the control inputs:
The two wiring versions are:
1) Switching to the external control input power sup-
ply. The switch will be linked between the control
input (X3.x) and the external power supply (Vext).
The ground return (GNDext) is permanently wired
with CREF (X3.7).
2) Switch to the ground return of the external power
supply. The switch will be linked between the con-
trol input and the external ground return (GNDext).
The external power supply (Vext) is permanently
wired with CREF (X3.7).
Voltage range of Vext : +12 ... 29VDC
X3.x: "x" for connector pin,
e.g. x=9

The control inputs only operate, if they are supplied with an
external voltage.
