Hard Over Time; Setting The Hard-Over Time; Checking The Rudder Drive (Rudder Reference Fitted) - Raymarine LIGHTHOUSE 3 Advanced Operation Instructions

Hard over time

The hard over time setting can be specified as part of the Dockside wizard and comes after setting
the rudder limit.
• The following information only applies to vessels without a rudder reference
• If you already know the hard-over time for your vessel's steering system: enter this time in the
Hard over time value box and select Continue.
• If you do NOT know the hard-over time for your vessel's steering system, select Continue,
proceed with the Checking the rudder drive procedure and complete the Dockside wizard. Once
the wizard is complete, proceed to the Setting the hard-over time instructions for information on
how to calculate and set the hard-over time.

Setting the hard-over time

On vessels without a rudder reference transducer, it is important to set a Hard Over Time.
Before attempting to follow this procedure ensure you have read and understood the Rudder Check
warning provided in this document.
To estimate your hard over time follow the steps below:
1. With the autopilot in Standby, manually turn the rudder / engine full to port. (For vessels with
power steering the engine should be running when turning the rudder.)
2. Open the sidebar by swiping right from the left side of the screen.
3. Switch to the Pilot sidebar.
4. Engage Auto mode.
5. Press the +10 button on the Pilot bar 9 times to ensure that the rudder moves hard over to
starboard.
6. Count how many seconds it takes for the rudder to move from hard over port to hard over
starboard. This is your hard over time.
7. Enter your hard over time in the. The hard over time setting can be accessed from the Pilot set-up
menu: Homescreen > Settings > Autopilot > Pilot set-up > Hard over time.
8. After setting the hard over time, observe the autopilot's behavior and if required, make small
adjustments to the Hard over time value until a satisfactory result it achieved.
Warning: Rudder check
If no rudder reference has been fitted you MUST ensure that adequate provision
is made to prevent the steering mechanism from impacting the end stops.

Checking the rudder drive (rudder reference fitted)

As part of the dockside wizard, the system will check the drive connection. Once it has completed
the check successfully, a message will appear asking if it is safe for the system to take the helm.
During this procedure the autopilot will move the rudder. Ensure it is safe to proceed before
proceeding.

1. Center and let go of the rudder.
2. Disengage any rudder drive clutch.
3. Select Continue.
4. Check it is safe to proceed and then select OK.
The autopilot will now automatically move the rudder.
5. Select OK when the rudder has moved to port.
6. Select OK when the rudder has moved to starboard.
