5.6 Signal connection for setting the ouput voltage
The unit has one-analog input: terminals
“
E1
”
/
“
GND
”
(Analog In 1).
At this input the potentiometer mounted in the cover for setting the output voltage is connected
(potentiometer outside). Voltage supply is made by terminal A1 (+10 V).
Alternatively the setting of the output voltage can be made by an external signal (0...10 V). For this
disconnect the potentiometer and isolate the connecting cables.

5.8 Voltage supply for external devices (+24V, GND)
There is an integrated power supply for external devices, e.g. a sensor. Te24 V, output voltage

Technical data.
It is not permissible to connect outputs of several devices to each other!
In case of overload or short circuit (24 V
–
GND), the external power supply is shut down (multi-fuse).
The device performs a
