Description
The canister position counts did not reach the empty canister check counts before the Color Change Timeout expired. If this occurs during a Scale Calibration, then the can was not empty before the Scale Cal Step Time expired. This condition can exist when no paint has exited the can, or if a loss of canister position feedback from the linear potentiometer has occurred. The Color Change Timeout needs to be increased. The Empty Can counts have not been properly calculated.
Remedy
Establish the cause of the timeout. Verify that the canister position feedback is operating properly. Feedback can be verified by checking the analog input (AIN[1, DISP]). Check the color change valve operation. Check the dump valve if the paint has not exited the canister. Increase the Color Change Timeout. If the gun has been changed then a scale calibration might be required. Reset, and attempt to continue if this occurs during automatic mode. If the robot is stuck in the docking station then, switch to manual mode and run a de-dock move to move the robot to Home. If this alarm occurs during a scale calibration then increase the Scale Cal Step Time (40 seconds by default). It could require more time depending on the material used to scale calibrate.
