D.4.1.4: 16-B B it Analog Input Without Flag ( Obj. 30, Var. 4 )
Analog Inputs support the following functions:
Read ( Function 1 )
A READ request for Variation 0 will be responded to with Variation 4.
Analog Inputs are used to communicate the following data measured by Shark meters:
•
Health Check
•
Phase-to-Neutral Voltage
•
Phase-to-Phase Voltage
•
Phase Current
•
Total Power
•

•
CT Numerator, Multiplier, Denominator
•
PT Numerator, Multiplier, Denominator
Health Check ( Point 0 )
The Health Check point is used to indicate problems detected by the Shark meter. A value of zero
( 0x0000 ) indicates the meter does not detect a problem. Non-zero values indicate a detected
anomaly.
Phase-to-Neutral Voltage ( Points 1 - 3 )
These points are formatted as 2's complement fractions. They represent a fraction of a 150 V
Secondary input. Inputs of above 150 V Secondary will be pinned at 150 V Secondary.
