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

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
Description
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
Description
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.
If the phase voltage is either missing or below the voltage
interruption threshold, the phase indicator is replaced with a
dash.
Display Features
The EM720 display has a number of programmable features

Backlight
A short press on any button while the display backlight is off
switches the backlight on.
The backlight stays on as long as you selected in the display
setup and then dims to conserve power. The backlight time is
factory set to 1 minute and can be programmed from 1 to 10
minutes. You can temporarily set the backlight to continuous
operation if you need to work in dark for more time.
