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 electrical measures of every phase.
When
Σ
L LED is ON, only the main display will be active showing the three-phase system value of the electrical
measure selected.
LED k and M show the eventual multiplying factor (k = kilo=x 1.000, M =Mega= x 1.000.000)
If it’s selected with the C key the display indicates also the values of the active, reactive and apparent energy
counters. If it’s selected with the A and B keys the display indicates the maximum and average values.
G
: display for the visualization of the electrical 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 (x 1000).
If it’s selected with C key the display indicates the type of the energy displayed. If it’s selected with A and B keys,
the display indicates the type of average of maximum values.
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.
