ZNRG2061 Evaluation Kit User Manual

Description

The ZNRG2061 Evaluation Kit is designed to help the user evaluate IDT’s ZNRG2061 Smart Photovoltaic DC Arc-Fault Detector IC. The kit includes the ZNRG2061 Evaluation Board with a sample ZNRG2061 mounted, a current transformer, and a micro-USB cable for connecting the kit to the user’s computer.

When the Evaluation Board is connected to the user’s computer via a USB port, the ZNRG2061 can be monitored for arc-fault detection. A test arc circuit enables self-testing of the device.

IDT’s ZNRG2061 Arc Analyzer Software provides a graphical user interface (GUI) to enable configuration, data analysis, and communication with the ZNRG2061 mounted on the Evaluation Board. The GUI is also used to activate the training sequence that allows the ZNRG2061 to adapt its algorithms for safe and reliable detection of arc faults The GUI is available for download on IDT’s website.

Restrictions in Use

IDT’s ZNRG2061 Evaluation Kit consisting of the ZNRG2061 Evaluation Board, 100:100 turns Current Transformer, and micro-USB cable, and the ZNRG2061 Evaluation Software are designed for demonstration and evaluation only. IDT’s ZNRG2061 Evaluation Kit and Evaluation Software must not be used for performance and characterization purposes.

Important Safety Warning: These procedures can result in high currents, which can cause severe injury or death

and/or equipment damage. Only trained professional staff should connect external equipment and operate the software.

Important Equipment Warning: Ensure the correct connection of all cables. Supplying the board using the wrong

polarity could result in damage to the board and/or the equipment. Check that all jumpers have been removed from the board before applying power.

1. Set up

1.1 User Equipment

The following additional equipment is required for using the kit:

 User’s computer (see requirements in section 1.2).

The following additional lab equipment is optional, but not necessary for the kit functionalities:

 Optional external power supply. The USB interface provides a +5V power supply to the Evaluation Board, from which an on-board voltage

regulator can provide 3.3V supply. Alternatively, the ZNRG2061 can be powered by the user’s external power supply (6V to 18V) connected to VIN + (X1-2) and GND (X1-2) as described in Table 1 (the rest of the Evaluation Board requires the 5V coming from the USB).

Note: The USB port only supports USB 2.0; USB 3.0 is not supported at this time.

1.2 User Computer Requirements and Setup

A Windows®-based computer is required for interfacing with the kit and configuring the ZNRG2061.

1.2.1 Computer Requirements

The user must have administrative rights on the computer to download and install the ZNRG2061 Arc Analyzer Software for the kit.

The computer must meet the following requirements:

 Windows® XP, 7, or 10  Supported architecture: x86 and x64  Available USB port  Internet access for downloading the ZNRG2061 Arc Analyzer Software.

1.2.2 Software Installation and Setup

To ensure use of the latest version of the software, the ZNRG2061 Arc Analyzer Software zip file is available for download in zip file format at no cost from the IDT web site page given on page 1. It is not included with the kit hardware.

Follow these procedures to install the ZNRG2061 Arc Analyzer Software zip file:

1. After downloading the zip file to the user’s computer, extract the contents of the zip file.

2. Double-click on the extracted setup.exe file to activate the installation.

3. Follow the standard installation instructions displayed on the screen and change the installation path if required. If the default path

settings have been used, the software automatically completes the installation and creates an access link on the user’s computer under Start > All Programs > IDT. The installation dialog offers the option to create a desktop short-cut icon for the software.
