FANUC Alarm PNT1-179 — Canister Fill Error

FANUC PNT1-179 (“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 >= TPR counts). First check: Make sure that paint has reached the docking station before starting the step to open the fill valve.

Description

Prior to painting the job, the can is checked to see if enough paint has been put into the can (cylinder position counts >= TPR counts). This can occur if the waiting for can full condition is falsely satisfied. Possible causes 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.

Remedy · Remède

Make sure that paint has reached the docking station before starting the step to open the fill valve. Try increasing the amount of time of the step to fill the paint line before opening the fill valve. With air in the can, after the piston pressure has been reapplied the air will compress causing the cylinder position to fall below the fill counts.
