Variable reading time-band energy counters (option)
20 pages to display the active energy counters (positive
and negative) and reactive (capacitive and inductive)
divided in 4 programmable time bands (P1 - P2 - P3 - P4).
The 20 pages are: consumption present year and the
two previous, consumption present month and the two
previous, consumption of today and the two day
previous, and total counter of bands.
In a voice of menu setup (paragraph 11.6) it’s possible
to program times, days and months in which the energy
count is added at the different bands.
External signals, connected to digital inputs, and with a
right programming, can change the bands in the time.
If the energy is Heavy the values are displayed in MWh
and MVArh.
Variable reading MIN & MAX values
12 pages (selected by “left” and “right” keys) show minimum and maximum of the value of 12
parameters taken after last reset. Date and time of reading are displayed on these pages.
It’s possible to see the values of these parameters:
