The control unit shown in Figure 2-1 on page 19 can operate as
a stand-alone unit in an autopilot system or it can be combined
in a multistation system. In a multistation system, command can
easily be transferred from one unit to another and units not in
control will display "Inactive".
The autopilot system may also be disabled from the ships’
steering system with an external switch. This will totally
disengage the autopilot system from the ships’ main/emergency
steering system and the units will display “DISENGAGED”.
The AP50 system is capable of the following primary steering
modes with each mode having a dedicated push button:
STANDBY (Follow-up and Non-Follow-up), AUTO, NAV and
DODGE. AUTO and NAV modes also have a sub-mode that is
accessed by pressing the WORK button. The AUTO-WORK
and NAV-WORK sub-modes are used under operational
conditions different from those normally found when a vessel is
in transit on a preset course (e.g. trawling, towing, trolling on
one engine, slow speed, using a thruster, etc.).
Each of the mode buttons is clearly identified with the primary
function in large text and a secondary function listed in smaller
text. Each button provides you with the ability to access a
primary display, a secondary display, and/or multiple function
displays.
A group of user-adjustable settings belonging to the selected
mode are provided in the AP50 User Set-up Menu (see page 38).
The settings allow adjustment of display visibility, selection of
heading sensor, navigation and position sources, and the ability
to select between automatically or manually adjustable sea state
filter.
Alarms are presented in plain text to alert you to both system
and external data failure conditions. Alarms include both audible
and visual presentations. The alarms are listed on page 165.
