The reversed polarity channel displayed under 'Polarity measurement inputs'.
If, for example, the phase Uen the REG-DP/ REG-DPA and Uen the current injection
controller (CIC) are different, the phase the U-sync-UneDPA input automatically rotated
until the absolute value and the phase match each other.1 can also performed directly the REG-DP/ REG-DPA.
If the polarity this channel reversed, automatic test will detect and correct it.9.
.
Current injection still after the test has finished and must switched off pressing
the 'OFF' key.
The values for Une (Uns) the current injection controller can viewed the second
line (in red).
One the Commissioning menu’s submenus 'Current injection'.
In the example, Une (Uns) connected channel the current injection controller.
Current injection also switched off when you exit the service screen.Page 210 Commissioning current injection
We take care it. Here, you can select au-
tomatic testing.
Une for the current injection controller and for the REG-DP/ REG-DPA must always be
measured the same spot.
The test can stopped any time pressing the 'OFF' key.2 Testing the REG-DP/ REG-DPA
