Immediate attention from a qualified operator or maintenance technician is required to prevent secondary damage to the equipment or spoiled parts during the manufacturing cycle. Always ensure standard safety and LOTO procedures are followed before accessing electrical cabinets.
Official Troubleshooting Steps
Cause: Too many user interface menus are active. The iPendant requires three menus which are always available for it to use. External browser connections require one menu for each window in use. Therefore, a browser connection might use a maximum of three menus - one for each of the three windows in triple window mode. Remedy: Eliminate some active browser windows or increase the number of menus in $UI_CONFIG.$NUM_MENUS. The total maximum number of menus is eight.
