8.8 Adjusting 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. On SmartPilot and SPX systems, adjust your Rudder Gain
setting to the maximum value, making a note of the original
value. The Rudder Gain setting can be accessed from the
Drive Setting menu:
Menu > Set-up > Autopilot Calibration
> Drive Settings > Rudder Gain .
2. 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.)
3. Engage Auto mode.
4. Press the +10 and +1 buttons at the same time (p70) or
use the Rotary (p70R) to alter your locked heading by 90
degrees, use a stop watch to time the movement of the
rudder / engine.
5. Estimate how long it would take to move the rudder from full
port to full starboard. This estimate is your Hard Over Time .
6. Enter this estimate as your Hard Over Time. The Hard Over
time setting can be accessed from the Drive Settings menu:
Menu > Set-up > Autopilot Calibration > Drive Settings >
Hard Over Time
.
7. On SmartPilot and SPX systems change your Rudder Gain
back to its original value.
8. After setting your Hard Over Time, observe your 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.
8.9 Sea trial calibration
Before you can use the autopilot open water checks are
required. The water must be calm, with light or no wind. Leave
plenty of room to manoeuvre. The Sea Trial wizard guides you
through the steps required for Sea trial calibration.
The Sea trial wizard includes the following steps:
• Swing compass
• Align compass to GPS
• Align compass manually
• Auto Learn.
You can access the Sea trial wizard at any time from the
Commissioning menu:
Menu > Set-up > Autopilot calibration
> Commissioning .
Note: Sailing vessels should perform the sea trial under
engine power.
Note: The Sea trial wizard can be cancelled at any time by
pressing the Standby button.
Warning: Seatrial calibration
Ensure you have sufficient sea room for calibration.
The seatrial calibration maneuvers require a clear,
familiar area of water. Ensure you are not likely to
collide with any vessel or other obstruction during
calibration.
Warning: Maintain sensible speeds
The autopilot may make unexpected turns.
Compass swing
You will need to turn your vessel in slow circles while the system
automatically makes adjustments to account for compass
deviation. Each 360-degree circle should take no less than two
minutes, and you should complete at least two circles.
1. Start moving vessel in slow even circles, then press
START .
2. Keep speed to below 2 knots. Watch the display to ensure
your turn rate is not too fast. If the message ‘Slow Down’ is
displayed reduce your rate of turn, this can be achieved by
slowing down and / or steering in a wider circle.
If a 'Slow Down' message is displayed the current circle will
have to be repeated.
3. When the compass has been calibrated, a message will be
displayed showing the detected deviation. If this is more than
15 degrees you will need to abort the calibration process
and resite the compass further away from metal items, then
repeat the calibration process. If you still find a deviation
of more than 15 degrees, contact your Raymarine dealer
for advice. If the deviation is within acceptable limits, press
CONTINUE .
You can cancel Seatrial calibration at any time by pressing
STANDBY .
Aligning compass to GPS
Note: Systems without a GPS will skip this section and go
straight to Manual compass alignment.
If your system has a GPS connected to your data network
(SeaTalk, SeaTalk
ng or NMEA), the autopilot is tuned to the GPS
heading while you steer to a known magnetic heading. This
step provides a rough alignment and minimizes the amount of
compass fine tuning required.
1. Steer the vessel on a steady course with minimal tide,
increase speed to more than 3 knots and press START to
align the compass to GPS.
2. Follow the on-screen instructions until the process completes,
press the CONTINUE button when it is available to begin
autolearn.
You can cancel Seatrial calibration at any time by pressing
STANDBY .
