Description
The maximum tensile force on the ball screw has been exceeded. When this occurs, its usually when the ball screw is retracting. There might be a vacuum in the canister which is causing excessive torque when the motor is retracting the canister's piston.
Remedy
Ensure that the retraction speed is not too fast during the fast fill cycle. Ensure that the pCI and pCC valves are open during the fill cycles.
