B
) for
Secondary line – which allows to select the measurements.

2.2 Measurement selection
•
When the key located under each display (
A
) and (
B
) is pressed several times, it will be
possible to view the various measurements of the line sequentially.
•
Line-to-line voltages, line-to-neutral voltages (in case of single-phase lines) are available
for each line.
•
The combinations of the red LEDs indicate which measurement is selected. The list of
measurements may change depending on whether the electronic control box is set up for
the three-phase, two-phase or single-phase control.
•
After 1 minute without touching the key, the measurement returns to the default mea-
surement, which may be the first voltage line-to-line or the first voltage line-to-neutral,
depending on how the voltage control is set up.
•
In case of alarms or messages, the display will be occupied by the alarm code.
By pressing the selection key, it is possible to temporarily hide the alarm and access the
measurements.
