4.2.2SETUP SOFTWARE

All configuration parameters not already covered through configu- ration switches can be changed through the setup software. Before configuring the PQ-8, you should print a self-test. A self-test printout shows all active configuration settings. Refer to this printout to determine which parameters may need to be changed through the setup software. To run this software, attach a PC or LAN printer server to the parallel sharing (PQ-8P) or to the serial sharing port (PQ-8S).

NOTE

A printer must be connected to the PQ-8 and in “Ready” mode in order for the PQ-8 to receive data from any of the ports.

Start your PC and go to the DOS prompt. Insert the setup software into the PC. At the DOS prompt, type A:SETUP and press Enter. The setup program will appear on the screen. Follow the instructions shown on the screen.

4.3 Host/PC Download Commands

By sending download commands from the Host/PC to the PQ-8, you can change all configuration parameters not already covered through the configuration switches.

Most Host/PC download commands are placed in a Host /PC document or on the screen. Regardless of whether the incoming print job is a screen print, a spreadsheet, or a word-processing document created on either the host or PC, the PQ-8 will recognize the Host/PC download command.

The command itself will not be printed if it was entered correctly. If any part of the command is printed, the PQ-8 did not recognize the command because of a problem in the format. Check the syntax of the command and send the command again.

Most Host/PC download commands sent to the PQ-8 take effect immediately and stay only in the PQ-8’s active memory. To save the changed configuration beyond a power off, Host/PC download command Z99,0 must be sent.

Tip: Save the Host/PC download commands in a separate file. If you need to re-configure the PQ-8 at a later time, or if you need to configure more than one PQ-8, just “print” the file containing the Host/PC download commands.

This capability is crucial for diagnosing issues such as voltage sags, swells, interruptions, and harmonics, which can lead to equipment malfunction or failure if left unchecked.

The PQ-8S is tailored for three-phase systems, making it ideal for industrial applications that require comprehensive analysis of three-phase power flows. Meanwhile, the PQ-8P, designed for single-phase applications, is particularly useful in residential or light commercial settings. Each model features an intuitive touchscreen interface, enabling users to navigate through data and settings effortlessly.

Data logging and extensive reporting are central to both models. They can store multiple parameters, such as voltage, current, and frequency, for prolonged periods, which assists in trend analysis and long-term monitoring. The onboard memory capacity allows users to access historical data for thorough evaluations and audits without requiring constant device connection.

In addition to their analytical prowess, the PQ-8S and PQ-8P emphasize safety and compliance. Both devices are designed with safety features that adhere to international standards, ensuring reliable performance in various environments. Their rugged design makes them suitable for both fieldwork and permanent installations, as they can withstand harsh conditions.

Wireless connectivity options enhance their usability, allowing for remote monitoring and real-time analysis from any location. This feature ensures that issues can be addressed promptly, leading to improved operational efficiency and reduced downtime.

In conclusion, the Black Box PQ-8S and PQ-8P power quality analyzers offer an impressive combination of features, advanced technologies, and practical characteristics. Their design and functionality make them indispensable tools for anyone looking to maintain optimal power quality in their electrical systems, thus ensuring reliability and efficiency in an increasingly electrified world.
