Manual econ sens+ Version 1.40
Installation check routine „Installation check“
The econ sens + has a small installation check routine, called "installation check".
General, it is assumed that all
measurement coils were installed
correctly, and the measured load has a
power factor of >0.71 (phase shift
between U and I <45 °).
Then the table of measurements in
Figure 20 is shown. In this example, a
load of about 6 kW measured at L1, L2
and L3 are unloaded.
Is an installation error, for example, the coil L2 is placed around the voltage circuit from L1, the power
factor falls below 0,71 and it appears in the table of measurements the following error message:
In the table of measured
values it can be seen that
the power factor of phase
2 has dropped below 0,71
and the phase shift
between U2 and I2 in the
graphic "Phasor" has
120°. This is a typical error
pattern for the above-
named Installation errors.
