4.3.- LED INDICATORS
The device has two verification LEDs:

To verify the
active energy�

To verify the reactive energy (according to version).
The weight of the LEDs is 20,000 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 .

4.4.- IMPULSE OUTPUT ( CEM-C31-T1 and CEM-C31-485-T1 models)
The energy meter has optocoupler type outputs capable of generating impulses at a previous-
ly programmed rate. (See
“6.2.1. IMPULSE OUTPUT WEIGHT”
and
”6.2.2. IMPULSE OUTPUT
TYPE”
