Maintaining and Troubleshooting the PanelView Plus 7 Standard Terminal

Proper maintenance and troubleshooting of the PanelView Plus 7 Standard Terminal is essential to ensure optimal performance and longevity of your equipment. Here we will provide you with guidelines for routine maintenance, common issues that may arise, and steps to resolve these issues. ### Routine Maintenance Regular maintenance of the PanelView Plus 7 Standard Terminal helps in avoiding potential issues and prolongs the life of your device. Here are some key tasks: 1. **Cleaning the Enclosure**: - Power off the terminal before cleaning. - Use a soft, damp cloth to wipe down the exterior of the terminal. - Avoid using harsh chemicals or abrasive materials that could damage the screen or enclosure. 2. **Changing Fan Filters**: - Regularly check and replace the fan filters to ensure proper ventilation. - Neglecting this can lead to overheating and reduced performance. 3. **Managing CRT Intensity**: - Adjust the screen’s contrast and brightness settings as needed to ensure optimal display visibility and reduce eye strain. ### Troubleshooting Common Issues Even with proper maintenance, you might encounter issues with your PanelView Plus 7. Below are some common problems and their solutions: 1. **Values Do Not Update on Display but Appear as Asterisks (****)**: - Ensure the terminal is communicating with the controller. - Check the COMM Status indicator for any issues. - Verify that the value does not exceed the field width defined for the object. Adjust the field width if necessary. 2. **Cannot Enter Configuration Mode**: - If pressing the Left and Right arrow keys simultaneously does not work, these keys might be assigned to screen objects. - Consult Allen-Bradley technical support for further assistance. 3. **Screen Objects Are Not Visible**: - Verify that the correct power is applied and the connections are secure. - Access the Configuration Mode menu to adjust the contrast or intensity. - Ensure the terminal is not in screen saver mode. - If the backlight is off or burnt out, replace the backlight. 4. **Application File Issues**: - If the application file name appears as ******* on the Terminal Info screen, the application might be invalid. Re-download the application and try again. - If an application is unusable due to an error, download a new version. 5. **Memory Card Issues**: - Ensure the memory card is properly installed. - Check for write protection settings and disable them if necessary. - If the application is too large, reduce the size of the file or use a larger memory card. - In case of an incorrect data checksum, ensure the card is installed correctly or try a different card. 6. **Clock Module Battery Low**: - If the "Clock Module Battery Low" message is displayed, it might indicate corrupt internal parameters. Reload the application and cycle power to the terminal. - Replace the clock module if there is a battery failure, following the instructions provided with the clock module kit. ### Fault Messages and Their Resolution 1. **Invalid Memory Card Format**: - Replace or reformat the memory card. If the problem persists, try another card. 2. **Communication Errors**: - Ensure the terminal and computer are set at the correct communication rate. - Verify that the terminal node and maximum node numbers are set correctly. - Check that the communication driver is properly loaded. - Disable printing on the Printer Setup screen if the printer port is enabled. 3. **Application Not Transferring**: - Ensure proper installation of the memory card. - Verify the application file is not too large and check the file format. ### Indicators and Their Meanings The PanelView terminals (excluding the PanelView 300 Micro) use the COMM and Fault Status indicators to help isolate operational problems. Monitoring these indicators can give you quick insights into the health and status of your terminal.
