1.
Touch the
icon. The display shows the
screen on the right.
Touch the
icon in order to set:
➢
The type of connection
➢
The nominal reference voltage and the percentage
of positive and negative thresholds for the detection
of voltage anomalies
➢
The ratio of possible VT transformers presents on
the installations
➢
The type and the full scale of transducers clamps
used for phase and neutral currents
➢
The aggregation time and the type of recording
start/stop
➢
The type of possible pre-set configuration
The display shows the following screen
2. Touch the interactive scheme to select the type of
connection among the possible situations of § 6.3.1.
Note the description in the bottom part of the display.
Touch the
or
icon keys in order to set the
nominal value
V
of the phase-neutral voltage (single-
phase or three-phase 4-wire systems) for the detection
of voltage anomalies (sags, swells) within the range:
12V
600V
. Press and hold the keys for a quick
selection of value.
Touch the
or
icon keys in order to set the
%
percentage of positive (sags detection) and negative
(swell detection) thresholds with respect to the nominal
voltage within the range:
3%
30%.
Press and hold the
keys for a quick selection of values
Touch the
or
icon keys in order to set the ratio
of possible VT transformers presents on the
installations within the range:
60
3000.
Press and
hold the keys for a quick selection of values.
With no
VT on the installation (direct connection) the value
of this parameter must be always 1
Touch the
icon in order to set the type and the full
scale of the used transducer clamps. The display
shows the following screen
