• If you already know the hard-over time for your
vessel’s steering system: enter this time during
the Dockside wizard procedure.
• If you do NOT know the hard-over time for your
vessel’s steering system: skip this step during the
Dockside wizard by selecting SAVE, complete the
Dockside wizard procedure. Once the wizard is
complete, calculate and adjust the hard-over time.
Checking the rudder drive
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 selecting
OK.
When in the Dockside wizard, with the Motor Check
page displayed:
1. Center and let go of the rudder.
2. Disengage any rudder drive clutch.
3. Select CONTINUE.
4. Check it is safe to proceed before selecting OK.
For vessels with a rudder reference transducer,
the autopilot will now automatically move the
rudder to port and then starboard.
5. For vessels without a rudder reference
transducer, you will be asked to conrm the
rudder turned to port by selecting YES or NO.
6. Select OK if it is safe to engage the rudder in the
opposite direction.
7. You will be asked to conrm the rudder turned to
starboard by selecting YES or NO.
8. Dockside wizard is now complete, select
CONTINUE.
Note: If you conrmed a “NO” response for the
rudder movement to both port and starboard, the
wizard will exit. It is possible that the steering
system did not move the rudder in any direction,
and it will be necessary to check the steering
system before completing the Dockside wizard
procedure again.
Note: If the rudder moves in the opposite direction
than expected you may need to reverse the phase
of the rudder reference unit. This can be achieved
by accessing: Pilot Set-up > Pilot Settings >
Drive Settings > Reverse Rudder Ref.
You can cancel Dockside wizard at any time by
pressing STANDBY.
Warning: Rudder check
If no rudder reference has been tted you
MUST ensure that adequate provision is
made to prevent the steering mechanism
from impacting the end stops.
Adjusting the hard-over time
On vessels without a rudder reference transducer, it
is important to set the hard-over time limits correctly,
to ensure accurate autopilot operation. Hard-over
time is the time it takes the vessel’s steering system
to drive the rudder from full port to full starboard.
Before attempting the following procedure, ensure
that you’ve observed and understood the Rudder
check warning provided in this document.
The following information only
applies to vessels without a
rudder reference transducer.
1. With the autopilot in ‘Standby’ mode, manually
turn the helm full to port.
2. Place the autopilot in ‘Auto’ mode.
3. Using a stopwatch, start the timer, and then
immediately:
4. Turn 180 degrees from your current heading.
5. Once the rudder has reached the rudder limit that
was specied as part of the Dockside wizard,
stop the timer.
6. To calculate your hard-over time, take the
measured time and double it.
7. Now access the Hard Over Time menu to specify
this hard-over time.
Setting the hard over time
Once the hard over time has been established it can
be set following the steps below.
From the Pilot Set-up page:
1. Select Pilot Settings.
2. Select Drive Settings.
3. Select Hard Over Time.
4. Enter your hard over time in seconds.
Compass linearization — Evolution
autopilots
The EV unit’s internal compass needs to compensate
for local and the Earth’s magnetic elds. This is
achieved using an automatic process known as
linearization.
Initial linearization
When the EV unit is rst installed and powered-up (or
after a factory reset or compass restart) linearization
is required. A progress bar is displayed to indicate
linearization is required.
