► To configure an Energy Meter
1
In
Meter Configuration > Meter Names
, enter the name of the meter.
2
Enter the input sources for the meter. These may be either Analog Inputs or System Value
Inputs:
Analog Inputs
In Meter Configuration > Analog Inputs, enter the inputs for this meter:
•
Meter number
•
Analog input number for the energy source.
•
Analog input function: current or voltage as appropriate.
If there is no analog input with Function = Voltage, the SC300 will use Bus Voltage
for its calculations.
•
To add more energy sources to the same meter, configure them as extra lines in
Meter
Configuration > Analog Inputs.
The meter power and energy will be the total of all
inputs mapped to the same meter.
System Value Inputs
The energy meter may also use the power, voltage, or current from a
System Value.
•
In Meter Configuration > System Value Inputs, enter the inputs for this meter.
•
For each input, set the System Input (and Index, where applicable).
If the System Value is a
power
value, this will be used directly as the meter power.
If the System Value is a
current
value, this will be multiplied by a voltage value mapped
to the energy meter (or the Bus Voltage if there is no voltage mapped) to give the meter
power.
If the System Value is a
voltage
value, a current value will also need to be mapped to the
same meter (otherwise power will be measured as zero).
A System Value may be another energy meter. So it is possible to add two or more energy
meters together to make a “Total Energy” meter.
► To reset an Energy Meter Power Minimum and Maximum values
In
Meter Configuration > Meters
, click on the appropriate reset button.
Energy meter power minimum / maximum can be reset per meter, or all at once.
► To reset an Energy Meter Energy value
In
Meter Configuration > Meters
, click on
Reset all Energy Meters
.
Press enter to confirm you wish to reset all energy value.
Energy values can only be reset all at once.
