Hard over time
Note:
Not applicable to boats with a rudder reference transducer.
On boats without a rudder reference transducer, it is of critical importance to set the
hard over time, to ensure accurate autopilot operation. To do this:
At a convenient Pilot Controller:
1. Press
MENU
to display the
Main Menu
.
2. Scroll to
Autopilot calibration
then press
OK
to display the
Autopilot Autocalibra-
tion
menu.
3. Scroll to select the
Drive settings
option then press
OK
to display the
Drive settings
menu.
4. Scroll to select the
Hard Over time
option then
press
OK
to display the
Hard Over time
page.
5. Measure the time it takes for the autopilot to
drive the rudder from hard over port, to hard
over starboard.
6. On the
Hard over time
page, scroll to set the
appropriate time in the edit box.
7. Press
OK
to save the setting and return to the
Drive settings
menu.
End of autopilot dockside setup
At the end of the autopilot dockside setup, use the
CANCEL
button to return to a Pilot
Controller operational page. Before starting any sea trial or other open water
calibration, carry out the
Transducer setup
and
Miscellaneous setup
procedures
(below).
Transducer setup
CAUTION:
Before starting any dockside setup procedure, ensure the boat is securely
moored alongside.
Use these dockside setup procedures to set:
•
Correct depth offset and sea temperature.
•
Required method for calculating ground wind.
•
Correct magnetic variation.
•
Required instrument response.
•
Trim tab calibration.
Introduction to transducer setup
Depth, speed and temperature data are derived from transducers in the boat’s hull.
Either of the following transducer configurations may be fitted to provide this data:
•
Conventional transducers, i.e. separate Depth and Speed, with the water temper-
ature sensor built into the Speed transducer.
•
Smart transducers (either combined Depth/Speed/Temperature (DST) or com-
bined Depth/Temperature (DT) transducers).
