NT888G MK2 AUTOPILOT OPERATING MANUAL
2.10 The REMOTE Key.
Operation of the “ REMOTE ” key (corner LED illuminated) specifies that the use of
Remote Autopilot Control Units and/or Remote Power Steer Units (Follow Up, Non
Follow Up etc.) is permitted and that their input signals will be accepted by the
Autopilot system.
Without “ REMOTE ” key operation, Remote Control Units/Power Steer Units will not
function.
The “
REMOTE ” key condition described above is applicable to all NT888G MK2
Autopilot systems employing a single NT888G MK2 Control Unit but, in systems
employing two or three (maximum) Control Units, only one of these units will be the
“
Master ” and the others will only gain access to the Autopilot system when the
“Master” Control Unit Remote key permits.
Under normal conditions, a Control Unit with address code No. 1 nominates itself
automatically for “Master” status and if two more (subordinate) stations are involved,
these will be programmed with address code
Nos. 2 and 3 (all Control Units must
have their own unique address code).
If it is later required to alter “ Master ” status from Control Unit No. 1 to No. 2 (or 3) the
“ REMOTE ” key of No. 1 should be activated (LED on) to allow entry by Nos. 2 and 3.
The nominated new “Master” (No. 2 or No. 3) should then be switched “ ON ” after
which the “ ON ” and “ REMOTE ” keys should be pressed simultaneously for a period of
5 seconds to complete “Master” status transfer.
When the High Speed Craft ( HSC ) operating mode is specified, all Remote station
inputs are “ REMOTE ” key dependent for system access as described above with the
exception of the OVERRIDE control which is active regardless of the “ REMOTE ” key
status.
2.11 The TURN MODE Keys.
There are two
TURN MODE keys which provide two special types of turn selection:-
(i) U TURN – permanent 180º course change.
(ii) NEXT COURSE – preprogrammed and stored next (new) permanent
course change facility.
2.11 (i) The U TURN Key.
The Autopilot software is programmed to order a 180º permanent course change from
whatever heading is currently ordered by the Set Course knob confirmed by the Set
Course value on the Control Unit display.
When the
U TURN key is operated (confirmed by flashing corner LED) the direction of
turn required to the new (reciprocal) heading must be defined within a timeout period
of 30 seconds by operation of the
- (Port) or + (Stbd) Control Panel key.
NB. Second operation of the U TURN key at any time will exit the U TURN mode.
