Product Usage Instructions

Safety Instructions
Ensure to read and follow all safety instructions provided in the user manual before operating the Ethernet Cable Guard.

Target group: This description is intended exclusively for trained, qualified personnel in control and automation technology familiar with the applicable national standards. Compliance with the hints and explanations in this operating manual is essential for installation, commissioning, and operation of the components.
Intended use: The device has an IP20 protection rating and must be mounted in an electrical control cabinet for protection against environmental influences. To prevent accidents, the doors of the control cabinet must be closed while the device is operated. Following the intended use can prevent personal injury and damage to the steering or the environment.
Operation: Proper operation of the device requires appropriate transport, storage, installation, commissioning, operation, and maintenance. Operate the device only in fault-free condition. Adherence to the permissible conditions and performance limits is mandatory. Modifications or conversions to the device are fundamentally prohibited.
Security: The device is a network infrastructure component and thus an important element in the security consideration of a plant. Follow the relevant recommendations to prevent unauthorized access to plants and systems.

Introduction
This document explains the initial commissioning of the Cable Guard. The latest version of the documentation and the manual can be found at www.helmholz.de or by scanning the QR code.

Function of the Ethernet Cable Guard
The Ethernet Cable Guard enables lifespan monitoring of Ethernet data cables (100Base-TX) with a focus on dynamic applications in automation technology, such as trailing cables on movable machine parts (robots). It increases plant availability and allows maintenance intervals to be planned, significantly reducing maintenance costs.

The Cable Guard is clamped onto the monitored cable strand and can inform about the status of the cable connection via a separate network connection or via a digital output on the quality of the cable connection. The feedback can be displayed as a PWM signal at the output, and the alarm threshold is individually adjustable (“lifespan” 99 – 50 %).

For integration into IoT structures, the monitored cable status can also be transmitted via MQTT through the Cable Guard.

Connection

Power Supply
The Cable Guard must be supplied with DC 18 … 28 V via the provided connection plug with DC 24 V.

Network
The Cable Guard has two RJ45 connectors, “DATA” for the monitored link. The monitoring cable (e.g., in a cable drag chain) must be connected to the lower “Guard” connector. The DATA connection must be linked to further standard industrial Ethernet cables.

Initial Commissioning
Please connect the device to the power supply and pay attention to the above instructions for use. Once the DATA connections are connected via Ethernet cables and the links are active (e.g., ports regular RJ45 connectors), the device’s correct function must be taught-in (this also applies to each cable change).

Website

Access to the Website
Connect the LAN port of the Cable Guard to your PC using a standard Ethernet cable. For the first call of the website, set the appropriate subnet on your PC’s network interface, e.g., with the IP address 192.168.0.1 with subnet mask 255.255.255.0 for LAN access. Open the website in a current browser with “https://192.168.0.324”.

Main View
After login, the “Home” website of the Cable Guard opens. The main view provides information about the device and cable status. For further information on configuration options, please refer to the manual.
