When the controller operates in complete three-phase connection mode (type C
connection diagram), pressing MODE several times, the three measurements referring
to L1-L2, L2-L3,L3-L1 are shown on the lower display.
This PF (Power Factor) value is determined by active and reactive energy meters of
the last 7 days and referred to positive energy quadrants only.
Overload current caused by harmonic voltage at the capacitor terminals.
Warning! When the NTC external sensor is not used, temperature is measured by the
internal sensor and can therefore be considered valid after a period of 20-30 minutes
from power on.
When these measurements are shown, the upper display indicates the order of the
harmonic selected instead of showing the actual cosφ. Use the + and - keys to scroll
from H02 (2nd harmonic) to H31 (31st harmonic) and then to THD (Total Harmonic
Distortion). To go immediately to THD, press -.
Use the + and - keys to select the harmonic event referred to the days of the last we-
ek, from E-0 (today), E-1 (yesterday) up to E-6 (six days ago) and lastly to E.HI
(maximum harmonic event recorded).
Use the + and - keys to select the step to which the measurement refers, from S01 to
Snn (where nn is the number of steps of the controller). The LED of the matching step
flashes to highlight the selection made.
