The IRB 120 robot has triggered alarm code 38200 (battery backup loss), which is related to the battery replacement. This analysis compares the left battery (no alarm) and the right battery (triggered alarm) to identify the fault cause.
1. Fault Phenomenon
The left battery operates normally without any alarms.After replacing the right battery, the robot triggers alarm code 38200 (battery backup loss) upon powering on.2. Battery Appearance Differences① Power Cable Orientation:
The left battery has a standardized power cable layout with consistent orientation; the right battery has inconsistent power cable orientation, showing significant differences.② Labels and Identifications:
The left battery has finely printed labels with clear fonts, including complete model, specifications, and brand identification.The right battery has poorly printed labels with blurred fonts, irregular layout, and simplistic identification content, clearly indicating it is a counterfeit product.③ Cell Packaging:
The left battery cells are packaged in transparent or semi-transparent materials, with clear brand and specification markings visible on each cell surface.The right battery cells are completely wrapped in plastic, with internal details not visible, suspected to be low-quality lithium or nickel-hydride batteries, possibly a “three-no” product.3.
