Rate of Consumption Indicator (Rate LED)
This red
LED provides the
reference
output for verifying the meter’s metrological accuracy. It also
provides a visual indication of instantaneous power consumption.
The
meter constant
for the 3-Phase meter is set to 1000 impulses/kWh. The
rate
LED will therefore
flash 1000 times for every kWh of energy consumed.
3.4
Optical Communications Port
This port enables data to be transferred to and from the meter (e.g. the accessing of various registers
or downloading of new parameters) us
ing a portable interrogation device. The optical port’s
communication protocol complies with IEC 62056-21 Mode C.
3.5

This yellow LED gives a quick, visual indication of several important meter statuses and provides a
useful diagnostic function to assist utility staff. During normal operation it flashes once every 5
seconds (effectively a
power on
indication). Two or more flashes occurring at regular intervals
indicate other status conditions as follows:

Customer Interface Unit Communications Indicator
This green LED gives a visual indication of communication status with a remotely connected customer
interface unit:
During normal operation, with a customer interface unit connected to the energy management unit,
this LED flickers continuously at the transmitted data rate.
If there is no communication with a customer interface unit, the LED glows steadily. This would be
the case if the customer interface unit were faulty or the communications lines broken (open
circuit).
If the communication line is short-circuited, the LED is off.
