The lift control system has detected that the lift is moving in the opposite direction of the issued lift command.
1. Lift Motor hysteresis.
2. Bad lower PCA
1. This error would typically happen when the lift was already in motion (typically downward)
when a lift command in the opposite direction (lift up) was issued. Some motors exhibited a
very long turn around time and the lift motor would still be moving in the original direction
(downward) while the control system was attempting to move the lift in the opposite direction.
If the error 45 condition is persistent, replace the lift motor.
2. This is a very rare condition, if the lift moves in the opposite direction of the issued liftcommand, replace the lower PCA.
