Units,
where the unit of the magnitude being viewed is shown.
Indicators,
which shows other parameters:
Indicates that the energy being viewed is generated.
Indicates that the energy being viewed is consumed.
Indicates that the energy is inductive.
Indicates that the energy is capacitive.
COM,
indicates that there is a communications module connected. It flashes when the
communications are established.
L1 - L2 - L3 -
Indicates the presence of voltage in each phase, with its corresponding
current direction:
“
-
“ is used to show the power yielded to the network.
“ “ is used to show the power absorbed by the network.
4.3.- LED INDICATORS
The unit has two verification LEDs:
To verify the
active energy�
To verify the
reactive energy
(according to version).
The weight of the LEDs is 4,000 imp/kWh (kvarh).
The LEDs will remain lit when the current is lower than the energy meter start-up current. Once
the start-up current is exceeded (due to active or reactive power consumption) the LEDs are
turned off and emit impulses that are proportional to the measured energy
.
