Default Meter Functionality

To learn more about the ION modules in your meter, refer to the ION Device Templates at www.pwrm.com. ION Device Templates list all of the ION modules available in the current version of your meter, and the total number of each module. ION Device Templates also show the ranges or options available for each module’s setup registers.

Basic Setup

Basic configuration of the meter is provided by the Power Meter module. The Power Meter module is the main connection between the power system measurements and all other ION modules in the device. This module reports the values for all voltage, current and power measurements.

The Power Meter module’s setup registers describe details of the power system being monitored. Many of the Power Meter module’s setup registers are configured when the meter is initially put into service, although the device will not operate properly until Volts mode and PT and CT ratios are set. Some registers may need to be changed to refine the device’s operation.

The functions of the setup registers in the Power Meter module are as follows:

Setup Register

Volts Mode 1

The power system’s configuration – WYE, DELTA, Single, etc

4W-WYE

PT Prim 1

The Potential Transformer’s primary winding rating for V1, V2

120

and V3

and I3

 

 

 

 

 

Vn Polarity

The polarity of the Potential Transformer on Vn

Normal

 

 

 

In Polarity

The polarity of the Current Transformer on In

Normal

 

 

 

Phase Order

The expected rotation of the voltage phases (ABC or ACB)

ABC

 

 

 

Phase Lbls

The phase label format assigned to the outputs (ABC, RST, XYZ,

ABC

RYB, RWB or 123)

 

 

 

 

 

1The registers are typically set when the device is commissioned. Changing the values of these registers while the device is in service is not recommended.

Once basic setup is performed (i.e. the PT/CT and Volts Mode settings), the meter operates properly. Typically there is no need to make further changes to the Power Meter module’s setup registers.
