No Load/Power Flow Direction Indicator
The power flow indicator gives information on the load
presence and shows the direction of active power.
Indicator Icon
No load.
Direct active power flow – imported (delivered) active energy.
Reversed active power flow – exported (received) active
energy.
Phase Presence Indicators
Phase presence indicators "123" show the status of either
V1-V2-V3 phase-to-neutral voltages in line-to-neutral
wiring modes, or V12-V23-V31 phase-to-phase voltages in
line-to-line wiring modes.
Indicator Icon
All voltages are present and above the voltage dip threshold.
Blinking phase indicator – the phase voltage is below the
defined voltage dip threshold. Possibly indicates an incorrect
meter nominal voltage setting (see
Chapter 5).
Dashed phase indicator - the phase voltage is either missing
or below the voltage interruption threshold.
If the phase voltage is below the defined voltage dip
threshold, its corresponding phase indicator is blinking.
Low lithium battery indicator with auto-reset.
Indicates that the battery voltage is below its
operational limit. The battery should be checked
and replaced. See the meter installation manual
for the battery replacement procedure.
The icon is automatically shut down after the
battery voltage returns to its normal value.
The battery date and operation time can be
inspected via the Device Info display (see
Info
Display). After replacing the battery, reset
the battery operation time via the reset menu
(see
Resetting Accumulators and Log
Electromagnetic field indicator with auto-reset.
Indicates presence of a high electromagnetic
field that can affect accuracy of energy
measurements. The electromagnetic interference
event start and end time are recorded in the
meter event log.
The icon is automatically shut down after the
electromagnetic field disappears.
Low
General diagnostic message indicator: indicates
that there are diagnostic messages you can
inspect via the DIAGNOSTICS display.
The icon is shut down after you explicitly reset
diagnostics messages either from the display or
via communications (see
Diagnostics).
You can disable diagnostic message indicator via
the Display Setup menu (see
