Description
An attempt was made to extend or retract the valve at SpeedDock side A or B, but failed.
Remedy
Check the retract or extend sensor at SpeedDock side A or B. If it was an extended fault, ensure that the pusher extended fully at Speed Dock side A or B. If it was a retracted fault, ensure that the pusher retracted fully at SpeedDock side A or B and that the valve is not stuck in the extended state. Ensure that sufficient air pressure is available for this operation and that the air lines are connected.
