We take care it.
In the example, Une (Uns) connected channel the current injection controller.
.
Current injection also switched off when you exit the service screen.
If the polarity this channel reversed, automatic test will detect and correct it.1 can also performed directly the REG-DP/ REG-DPA.
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.
Current injection still after the test has finished and must switched off pressing
the 'OFF' key.2 Testing the REG-DP/ REG-DPA
The automatic polarity test for the measurement channels for the current injection de-
scribed Chapter 13.9.
The values for Une (Uns) the current injection controller can viewed the second
line (in red). Here, you can select au-
tomatic testing.
One the Commissioning menu’s submenus 'Current injection'.
Une for the current injection controller and for the REG-DP/ REG-DPA must always be
measured the same spot.9.
