DESCRIPTION FRONT PANEL– OPERATORS
LEGEND:
A
:
push-button for the visualization of electrical parameters of three-phase system with the corresponding LED
indication. In modality programming (SETUP) it’s used to confirm the parameter set.
B
:
push-button for the selection of the electrical parameter to be displayed on display
F
. In modality programming
(SETUP) it’s used to increase the value of the parameters to set.
C
:
push-button for the selection of the electrical parameter to be displayed on display
G
. In modality programming
(SETUP) it’s used to reduce the value of the parameters to set.
D
:
LED bar for the indication of the electrical parameter displayed on display
F
.
E
:
LED bar for the indication of the electrical parameter displayed on display
G
.
F
:
3 displays for the visualization of every phase measures. When
L
LED is ON, only the main display will be active
showing the three-phase system value of the measure selected. LED
k
and
M
show the eventual multiplying factor:
k=kilo=x1000, M=Mega=x1000000. Using the
C
key the display indicates also the values of the active, reactive and
apparent energy counters. Using the
A
and
B
keys the display indicates the maximum and average values.
G
: display
for
the
visualization
of
the
measure
indicated
in
LED
E
(energy
counters
excluded).
The
voltage
values
are
referred
to
the
three-phase
system.
The
k
LED
displays
the
reading
in
kilo
(x1000).
Using
the
C
key
the
display
indicates
the
type
of
the
energy
displayed.
Using
the
A
and
B
keys,
the
display
indicates
the
type
of
average
or
maximum
value.
A+C
: when pressing simultaneously the instrument pass to the following menu: instrument programming (
SETUP
),
energy counters and peak values deleting (
RESET
), digital outputs programming (
SET
DO1
;
SET
DO 2
) (only
for version with digital output), hour counter programming (
HR_
), I/O diagnostic page.
A+B
: when pressing simultaneously the instrument pass to the visualization of average and maximum values stored.
MENU OF INSTRUMENT PROGRAMMING (
SETUP
)
To
enter
in
SETUP
it’s
necessary
to
press
at
the
same
time
A
and
C
keys,
on
the
F
display
will
appear
the
message
SETUP
.
Pressing
the
A
key
on
the
G
display
will
appear
the
message
SET
that
will
remain
always
displayed
during
the
set
of
each
parameter
to
highlight
the
SeTUp
phase
in
running.
The
set
values
will
be
keep
also
in
absence
of
auxiliary
power
supply.

DIGITAL OUTPUTS
Digital outputs:
the DO1 output is used as PULSE and it's linked
to the ACTIVE energy counter,
the DO2 output is used as PULSE and it's linked
to the REACTIVE energy counter.
DO1 and DO2 can be used as ALARM and
linked to a measured parameter.
Max 150mA
Max 230Vac/dc
