•
Average Power
Storing of average active and reactive power.
Enable
, it’s possible to enable or disable the storing.
The sampling time is fixed by Time Avg (default 15 minutes).
•
Harmonics
Up to the 31
st
harmonics are stored for each line both of voltage
and current channels.
Enable
, the user may enable or disable the storing of harmonic
values.
The sampling time is fixed at 15 minutes and it’s not modifiable.
•
Trigger
Enable
, the operator may enable or disable the
Trigger
function
If
Enable
is
OFF
the enabled archives store the measures with the relative rate, all of time.
If
Enable
is
ON
, the enabled archives store the measures with the
relative rate only after the receiving pulse on digital input 2 (DI2).
The storing will be active for the set time in
Time
. If there is no
enabled archives the trigger function has no effect.
Time
defines when the storing time is active.
With a logic level 1 (voltage present) on the digital input 2 (DI2) the
timer relative to
Time
will be reset and the storing enabled. Only when the signal go down, the
counting starts. The range is 1÷9999 minutes and the default value is 60 minutes.
If any of the above mentioned parameters has been enabled for
storage, by exiting the setup menu a brief message will appear,
asking at the operator to erase all the previous stored data, in the
memory, in order to enable a new recording campaign at empty memory with no residual
information’s.
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.
The data downloaded on PC using NRG software or communication protocol does not come deleted
and for this reason it’s possible to recover them using the function of communication protocol.
