h2000 Autopilot User Manual
Part 3 - Commissioning and Calibration
HB-0842-04
3-20
All B&G paddle wheel type speed sensors are compatible. The
Hertz/Knot value is entered into the system to ensure the autopilot
steering response is controlled with reference to boat speed. The
default Hertz/Knot value is 3.80; this is the default setting for B&G
speed sensors.
To determine if the value is correct compare the boat speed value
displayed by the autopilot display (when the Speed Key is
pressed) with the displayed value of speed on the
log/speedometer fitted.
3.4.9 Setting the Speed Calibration Value
(1) Select S CAL from the menu.
(2) Adjust the value with the < > Keys.
(3) Press Enter to set the value.
Note
The speed cal reading is inversely proportional; i.e. to increase the
boat speed, decrease the Hertz/Knot value.
3.4.10 Rudder Gain (R GAN)
When the autopilot is part of an integrated system, boat speed
data is supplied via the Fastnet cable from the h2000 Instruments.
By monitoring boat speed and rate of turn the autopilot will
automatically 'learn' the correct value for Rudder Gain giving a rate
of turn of approximately 6
o
per second for a sail boat or 8
o
for a
power boat.
If there is no direct speed input or the speed is being set by the
Autopilot Display Manual Speed Band selections, then the Rudder
Gain value must be entered manually; for these types of
installations omit this section and proceed to Manual Rudder Gain.
