Default Meter Functionality

The following sections describe the default functionality defined by your meter’s framework. With each advancement of firmware, there are changes to the framework, so your meter operation may differ slightly from what is presented.

The ION Device Templates documentation lists all the ION modules available in the current version of your meter, lists the total number of each ION module, and shows the ranges or options available for each module’s setup registers. The ION Devices Templates documentation is available at www.pwrm.com.

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 cannot operate properly until the Volts Mode and PT and CT ratios are set. Some registers may need to be changed to refine the device’s operation.

Setup	Function	Default
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 and V3	120
PT Sec 1	The Potential Transformer’s secondary winding rating for V1, V2 and V3	120
CT Prim 1	The Current Transformer’s primary winding rating for I1, I2 and I3	5
CT Sec 1	The Current Transformer’s secondary winding rating for I1, I2 and I3	5
V4 Prim 1	The Potential Transformer’s primary winding rating for V4	120
V4 Sec 1	The Potential Transformer’s secondary winding rating for V4	120
I4 CT Prim 1	The Current Transformer’s primary winding rating for I4	5
I4 CT Sec 1	The Current Transformer’s secondary winding rating for I4	5
I5 CT Prim 1	The Current Transformer’s primary winding rating for I5	5
I5 CT Sec 1	The Current Transformer’s secondary winding rating for I5	5
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, RYB,	ABC
	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.
