Ensure that this valve is always open when the system is in operation. It is a feed back mechanism of steering gear which repositions the floating lever of hydraulic pump as the tiller moves to the desire position. In effect the autopilot 'learns' the vessel's handling characteristics in calm weather and then, when the weather deteriorate, can distinguish between those errors in heading due to the weather and those due to vessel's normal handling characteristics. Alarm Notification Pipelines control how and when notifications are sent to users. I noticed the boot for the ball stud was off-centered and was pushing the ball stud (along w/ the spool valve) to one side. INTRODUCTION TO CONTROL SYSTEM. Lets see what the actual requirement is!
