5 Power Supply and Auto Power On
The tool is powered with 24 VDC either through the external AC adapter or by
using the single-ended cable for direct 24 VDC power supply. Both are
included in delivery.
Attention: Before being connected to the AC mains power, the
PROFIBUS Tester 4 and the AC adapter must be acclimated to room
temperature to avoid condensation. This may take up to 60 minutes.
The tool switches on automatically when you connect it to a power supply. The
display lights up and self-test starts.
Attention: When the tool is connected directly to 24 VDC, there is no
galvanic isolation to the external power supply. Insufficient potential
equalization between the power supply and the PROFIBUS will lead
to equalizing currents which can falsify the test results and, in the
worst case, even destroy the PROFIBUS Tester 4 and part of the bus
installation. In these cases, use of the supplied AC adapter is
mandatory for operating the PROFIBUS Tester 4.
On completion of initial setup, the PROFIBUS Tester 4 displays the following
dialog in English:
You can now select the desired display language. The following languages are
available: German, English, French, Italian, Polish and Spanish.
