FANUC Alarm PAIN-261 — WARN Canister Fill Error

FANUC PAIN-261 (“WARN Canister Fill Error”): Prior to painting the job, the can is checked to see if enough paint has been put into the can (cylinder position counts >= TPRcounts). First check: N/A

Updated 2026-09-17 · LogrobotLM reference

Description

Prior to painting the job, the can is checked to see if enough paint has been put into the can (cylinder position counts >= TPRcounts). This can happen if thewaiting for can full condition is falsely satisfied. Possible s are air in the canister due to faulty color change cycles or unstable readings from the linear potentiometer. Many times this happens because the air has not been pushed out of the dump before the fill valve is opened.: Make sure that paint has reached the docking station before starting the step to openthe fill valve. A fix could be increasing the amount of time ofthe step to fill the paint line before opening the fill valve. With air in the can, once the piston pressure has been reapplied the air will compress causing the cylinder position tofall below the fill counts.
