Code SEAL-220: Volume out of range (E%s)
Issue Description & Safety Warning
The Fanuc R-30i Series Robot Controller has triggered a critical Volume out of range (E%s) alarm. 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: The volume dispensed in the last job was out of the normal volumetric range of material dispensed for this job. This could be caused by terminating the job early, causing much less material to be dispensed. This could also be caused by problems with the material, such as using material which has exceeded its shelf life. Remedy: This warning is normal if it was caused by terminating a job early. If this error happens during normal production, examine the quality of the dispensed job and verify that the dispenser and material are in good condition.
