D.4.1.4: 16-BBit 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
• Three Phase Total VAs
• Three Phase Power Factor Total
• Frequency
• Three Phase +Watts Max Avg Demand
• Three Phase + VARs Max Avg Demand
• Three Phase -Watts Max Avg Demand
• Three Phase -VARs Max Avg Demand
• Three Phase VAs Max Avg Demand
• Angle, Phase Power
• Angle, Phase-to-Phase Voltage
• CT Numerator, Multiplier, Denominator
• PT Numerator, Multiplier, Denominator
Q
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.
Q
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.
