NT888G MK2 AUTOPILOT OPERATING MANUAL
2.4 The CONTROLS Menu (Continued).
2.4 (i) Adaptive / Non Adaptive Selection.
The Adaptive and Non Adaptive operating modes are briefly discussed in
Section 2.3 and, in most cases, Adaptive selection will be preferred.
NB. Adaptive (automatic) “Weather” control adjustment is a Type Approval
requirement of High Speed Craft (HSC) Autopilots thus the Adaptive Mode must
be selected for HSC applications.
a) Use the “ CONTROLS ” key to enter the Controls Menu.
b) Use the “ CONTROLS ” key again to select “ ADAPT ” box followed by
flashing “ ON/OFF ”.
c) Use the rotary (+/-) illumination control to select “ ON ” or “ OFF ” as
required (Adaptive mode “ ON ” or “ OFF ” where OFF = PID).
2.4 (ii) Rudder Control.
In the Adaptive Mode, the “value” of the RUDDER parameter will be found
automatically (after initial Sea Trial calibration) by reference to input speed and
draft data etc. Even so, the
RUDDER value can be manually changed – if required
to immediately optimise the steering performance – via the CONTROLS Menu.
If Non Adaptive operation is in use, it will always be necessary to adjust the
RUDDER value manually – again via the CONTROLS Menu.
The Rudder Control defines the angle of Rudder that shall be applied in relation,
or proportion to course error (degrees off course).
The Control value is 1 to 9 (as shown against RUDDER in the CONTROLS Menu)
and minimum Rudder is applied at a setting of 1. Maximum Rudder is therefore
applied at a setting of 9 and a 3:1 ratio exists between minimum and maximum
settings.
The factory default setting (accessible via the Set Up Menu) initially provides a
Rudder Control range of 0.5
o
to 1.5
o
of Rudder per degree course error.
The Rudder Control value (1 to 9) is adjustable as follows:-
a) Use the “ CONTROLS ” key to enter the Controls Menu.
b) Use the “ CONTROLS ” key again to select “ RUDDER ” box
followed by flashing value “ 1-9 ”.
Adjustable control parameters are listed on the
right side of the operational display (as shown)
and each item is selected by further use of the
“CONTROLS” key highlighted buy a blue bar to
confirm parameter selected. The value – or state
– of the chosen item is then changed via the
rotary (+/-) illumination control.
