Measurement Selection; Leds - Legrand 261 93 Mode D'emploi

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.

three-phase control.

• After 1 minute without touching the key, the meas-
urement returns to the default measurement, which
may be the first voltage line-to-line or the first volt-
age 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 meas-
urements.
