10.6) STORAGE
The STORAGE menu allows the programming of the data to store. 4 section of storing exist:
-
relative minimums and maximums
-
average powers
-
harmonic components
-
samples (only with NRG software or serial command)
The storage is organized as FIFO (first in first out) type memory. When the memory is full older data
will be overwritten by new data.
•
MIN - MAX
Up to 12 MIN & MAX parameters can be stored among the
following:
- three-phase system voltage (
Σ
V
L-L
/3)
- phase L1 voltage (V
L1
)
- phase L2 voltage (V
L2
)
- phase L3 voltage (V
L3
)
- three-phase system current (
Σ Ι
)
- line L1 current (I

)
- line L2 current (I

)
- line L3 current (I

)
- three-phase system active power (
Σ

- three-phase system apparent power (

Enable
, with ON the Min/Max storing is enabled while with OFF
it’s disabled.
Rate
, acquisition time.
This is the acquisition time of minimum and maximum values:
from 1 minute to 9999 minutes. For example to store the
minimum and the maximum value of programmed parameters
each 15 minutes it’s necessary to set 15.
Measures
, parameters to store.
It allows the selection of the measure to store in minimum and
maximum values. To press UP key to enable and DOWN key to
disable the variable selected from RIGHT and LEFT keys. If there
is an asterisk the selected measure is enabled.
Warning.
If the storing of minimum and maximum values is enabled the values shows in the relative
page are updated at the same acquisition time set for the storing in memory. Minimum and maximum
values are not absolute any more.
