Description
The maximum compression force on the ball screw has been exceeded. When this occurs, it is usually when the ball screw is extending.
Remedy
Ensure that the canister speed is not too fast when spraying the job. Ensure that the pTrig and pCE valves are open during job execution. Ensure that the injector tip is not clogged. The nozzle tip tapers to a smaller diameter; ensure that the paint did not dry inside the nozzle, causing it to clog. Ensure that the pDUMP valve is operating correctly during the cleanout cycle. If the ball screw is worn out, then it needs to be replaced.
