5.5.- CONNECTION TYPE
In this point the connection type of the installation
is selected, where:
3u3C: 3 voltages + neutral and 3 currents.
3u1C: 3 voltages + neutral and 1 current.
2u1C: 2 voltages and 1 current.
Press the key to enter editing mode. It is identified by the symbol and the blinking
of the digits to be modified.
The key shows the next option.
The key shows the previous option.
Press to validate the data; the symbol disappears from the display.
Press the key to access the next programming step.
If no keys are pressed for 5 minutes, the unit switches to the simulation screen, “5.27.-
SIMULATION SCREEN”.
5.6.- PHASE CONNECTION
This parameter is used to adapt the unit to the various options for connecting the power supply
and measurement cables and the current transformers to the phases of the three-phase
system.
The connection screen changes according to the connection type programmed in the preceding
point.
Connection type 3u1C or 2u1C
If a connection with a single current has been
selected (3u1C or 2u1C), one of the 6 possible
phases indicated in Table 41 are selected in this
screen.
The selection of one or another of the options
must be made when inductive reactive power with
an inductive cos φ of 0.6 to 1 is being consumed
in the installation at the time of adjustment. The
various options are tried until the screen shows a
cos φ of 0.6 to 1 (the display of the cos φ is only
informative, not editable).
