The annunciator icon indicators represent the following:
Icon
Name
Description
Battery status
Indicates when the measured battery voltage is lower than the
programmed threshold, or the cumulative power failure duration
exceeds three years.
Alarm
Indicates when the meter has detected an active alarm condition.
Excess demand
Indicates when the calculated demand value is higher than the
programmed threshold.
Communication
Indicates that there is active communication in progress between the
meter and an external device.
Phase
Each of the three icons represent a connected phase.
•
If a phase is missing, the associated icon is not lit.
•
If voltage sags or swells occur on a phase, the associated icon will
blink.
Quadrant
The four individual arrow icons indicate the direction and type of the
energy currently measured by the meter.
•
Active and Reactive
•
Import and Export
If the incoming supply phase-sequence is incorrect (e.g. 1,3,2) these
icons flash.
The following examples show the effect meter configuration parameters such as scaler, number of digits and
decimal places, have on the display.
Example 1
The energy channel configured in Wh and the value is
123 456 789 Wh.
Depending on the scaler value the reading via COSEM read out would be:
•
123456789*Wh
•
123456,789*kWh
