NT888G MK2 AUTOPILOT OPERATING MANUAL
2.36 Setting and Confirming New Autopilot Courses … (Continued).
Prolonged rotation will automatically result in
larger changes “per click” to make large
course changes viable by avoiding the need
for multiple turns.
(6 clicks @ 0.5°, 6 @1° then 2°).
A new course can be ordered up to 359° when
the vessel will always turn in the direction of
rotation of the Set Course Control.
The need for new course confirmation (if
required) can be programmed via the SET UP
Menu in 5° steps from 10° to 90°.
Actual set course and new course data is
shown on the Control Unit display whether
manually or automatically (Track) ordered.
TURN MODE key selection of U TURN or
NEXT COURSE always requires CONFIRM
(+) or CANCEL (-) key use to specify direction
of turn (+ = Stbd, - = Port).
Single CANCEL/CONFIRM key operation is all that is required to initiate a turn to new
course following Set Course control rotation or to order 1º step course changes.
(Sections 2.12 & 2.13 refer).
A Control Unit generated alarm requesting confirmation (CONFIRM key) is subject to
a programmable timeout period (20 to 60 seconds via the SET UP Menu) during
which confirmation is required – and beyond which – the new course request will
automatically be cancelled. (Section 2.12 refers).
U TURNS and NEXT COURSE programmed turns could be potentially dangerous if
inadvertently activated. A second CONFIRM key operation is therefore required after
ordering direction of the turn and, if the U TURN Mode is selected without follow up
action, the mode will automatically be deselected after a timeout period of 30
seconds. (Section 2.11 refers).
2.37 Setting the Watch Alarm Period.
The Autopilot Watch Alarm provides a simple audible and visual timing function
programmable from 3 to 12 minutes (or may be switched OFF) via the LIMITS Menu.
At the end of the time interval selected (3 to 12 mins)
the Control Unit alarm will sound and is cancelled by
single operation of the
TEST/OFF
keypad. A new
timing period will automatically commence whenever
the
TEST/OFF
key is operated.
