EMA11 - USER MANUAL

11.7) STORAGE

The STORAGE menu allows the programming of the data to store. 4
archives 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.

•

MINMAX

The acquisition time is expressed in minutes, up to 12 MIN & MAX values
are stored.

Enable

, confirming the “ENABLE” voice the operator may enable (ON) or

disable (OFF) the acquisition of MIN & MAX values.

Measures

, parameters to store.

Select the variable to store in the minimums and maximums with the
“LEFT” and RIGHT” keys, enable or disable this variable with “UP” and
“DOWN” keys.

Rate – min

.

, acquisition time.

This is the acquisition time of minimum and maximum values: range 1 ÷
9999 minutes. For example to store the minimum and the maximum value
of programmed parameters each 15 minutes it’s necessary to set 15.

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.

•

AVG.POW. (Average Power)

Storing of average active and reactive power. It’s possible to enable or disable the storing. The
sampling time is set at 15 minutes but it’s modifiable (

Time Avg

).

•

HARM. (Harmonics)

Up to the 31

st

harmonics are stored for each line both of voltage and current channels.

Enable

, the operator may enable or disable the storing of harmonic values.

The sampling time is fixed at 15 minutes and it’s not modifiable.
