Overview

Voltage registers are configured in much the same way as power registers (the default register type on the eGauge). Follow the steps in this article to add a register to record Voltage input.

Prerequisites

To make settings changes you will need access to the eGauge interface and valid login credentials.

• These steps assume a minimum firmware version of 4.0.  Instructions for earlier versions are at the end of this article.

Instructions

Step 1: Access the Installation Settings page by navigating to Setup → Other settings. Then click Installation to the right.

Step 2: Under Registers, click the "Add Register" button

Step 3: Name the register as appropriate.

Step 4: Using the dropdown menu, change the register type from "P" to "L"

Step 5: In the next dropdown menu, select the appropriate voltage reference.

• L1, L2, L3 use the high-voltage AC line inputs relative to N terminal
• L1-L2, L2-L3, L3-L1 use the high-voltage AC line inputs as line-to-line voltages
• D1, D2, D3 use the high-voltage AC line inputs with a virtually calculated neutral (not commonly used and still requires N connection)
• Ldc uses the 2-pin DC voltage input

Step 6: In the final dropdown menu select the measurement type.

• normal value records RMS voltage (e.g., for AC voltages)
• DC-only (mean) value records the mean value (e.g., for Ldc input)
• frequency records the frequency of the input. Frequencies are counted as zero-level crosses, so DC voltages will typically display 0 Hz.

Step 7: Repeat these steps to add additional registers, if needed.  Click Save at the bottom of the page to save your changes.

Legacy (pre firmware 4.0)

1. Navigate to Settings → Installation
2. Under Registers, click the "Add Registers" button
3. Name the register as appropriate
4. Using the dropdown menu, change the register type from "P" to “V”
5. A second dropdown menu will appear.  Select the appropriate voltage reference
6. Click "Save" at the bottom of the page when finished (valid credentials required)
