Current injection stays after the test has finished and must switched off pressing
the 'OFF' key.Page 244 Commissioning the HPCI
We take care it.
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. The reversed polarity channel displayed under 'Polarity measurement

.
Current injection also switched off when you exit the service screen.
The values for Une (Uns) the current injection controller can viewed the second
line (in red).
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 input automatically rotated until
the absolute value and the phase match each other.
In the example, Une (Uns) connected channel the current injection controller.
If the polarity this channel reversed, automatic test will detect and correct it
