Warning!
Automatic pilots are designed to be a navigational aid. As an automatic
steering aid, an autopilot can alleviate t e boredom of and steering.
T is allows t e operator of t e vessel time to attend to ot er duties, keep
a more accurate c eck of navigation duties or just relax and enjoy t e
trip.
HOWEVER, THE AUTOPILOT SHOULD NOT BE
LEFT SOLELY IN CHARGE OF THE VESSEL AND AN
ADE UATE WATCH SHOULD BE MAINTAINED AT
ALL TIMES.
IT IS STRONGLY RECOMMENDED THAT THE
AUTOPILOT SHOULD NOT BE USED WHILE
NAVIGATING IN RESTRICTED WATERWAYS AS
WATER CURRENTS, WIND CHANGES OR RADIO
TRANSMITTER INTERFERENCE CAN ENDANGER
YOUR OWN OR OTHER VESSELS.

Introduction
Congratulations on your wise c oice and purc ase of t e TMQ AP46
Autopilot system. We are sure t at you will enjoy t e benefits t at it
offers.
AP46 Autopilot System
T e AP46 Autopilot system comprises t e following units: -
Essential Electronics:
•AP46 display and control ead.
•Rudder feedback unit.
•Elproma Compass ECS1
•Drive unit, for example
-Hydraulic system wit solenoid valves.
-Reversing ydraulic pump system.

Block Diagram of full system
T e AP46 ead provides full control of t e autopilot, indicating in
different modes eading, course to steer and rudder angle.
It requires a supply voltage of 12 volts DC.
T e Rudder Feedback Unit (RFU) must be attac ed to t e steering tiller
device in suc a way t at it can accurately measure t e movement of t e
s ip’s rudder (see Rudder Feedback Installation diagram page 25). T e
RFU must also be electrically connected to t e AP46 Head unit.
Rudder actuator system: t is system provides t e p ysical movement to
t e rudder responding to t e direction control signals provided by AP46
system. A rudder actuator system comprises t e following: -
Hydraulic Ram - controlled by eit er: -
1. Reversing motor and pump unit, connected into an existing
ydraulic steering system;
2. Solenoid valves connected into an existing power steering
system; or,
3. Solenoid valves connected to a continuous running motor and
pump unit.

Definition of Terms
AP46 Display:
T e Operation unit, wit LCD Display and pus buttons.
Rudder Feedback Unit (RFU):
T is provides t e required rudder position information for
steering control.
Heading:
T is is t e magnetic eading of t e vessel at t e current time.
Course-to-steer:
T e magnetic eading w ic t e autopilot is attempting to
maintain.
Overview of Operation
•MANUAL Mode: “H***”
T e autopilot display unit s ows t e current magnetic eading.
T e vessel is under manual steering control; the autopilot will not
apply any steering control.
•AUTO Mode: “A***”
TMQ AP46 Autopilot Page 7 of 34 Ver1.0 07/03/2007
T e autopilot will maintain your vessel on t e magnetic course
indicated. T is course can be set or altered from t e display unit.
•GPS Mode: “A***”
W en receiving information from a GPS unit, t e autopilot can steer
a vessel to a precise latitude and longitude (waypoint), or t roug a
sequence of latitudes and longitudes (route).
•RUDDER and RESPONSE Settings:
T ese customise t e AP46 Autopilot for your vessel’s steering.
T ey may also be used to adjust for varying sea conditions.
•Rudder Angle Displays:
T e AP46 display unit LCD can be set to display t e rudder angle as
a numeric number.
•Backlighting:
W en using t e autopilot at nig t, t e backlig ting can be turned on.
•Jog Mode:
W en t e autopilot is in manual mode, t e port or starboard buttons
may be pressed and t e steering will be driven in t at direction.

Turning the unit ON / O
The power to the AP46 unit should be connected via a
suitable 15 amp circuit breaker.
MANUAL Mode
In t is mode
•T e display screen s ows “H***” ; (***) being t e current vessel
magnetic eading in degrees.
•No steering control is generated.
AUTO Mode
•Press t e AUTO button. AUTO mode will be selected. A beep will
sound and t e text display will c ange to “A***”. T e Auto LED
will lig t
T e autopilot will lock on t e current eading.
T e course-to-steer is s own on t e display.
Disengaging AUTO mode:
Press t e AUTO button, a beep will sound and t e vessel will
return to manual steering.
Course Adjustment:
Eac press of t e < or > buttons will give a course c ange of 1˚
in t e applicable direction. T e display will c ange to indicate
t e new course-to-steer. By pressing and olding t e buttons
TMQ AP46 Autopilot Page 9 of 34 Ver1.0 07/03/2007
pressed t e course c anges in 10 ˚ increments. T is is used for
larger turns.
IMPORTANT!!
Before entering AUTO mode, ensure that the rudder
is in the centre position (ie: the vessel is steering
approximately straight ahead). If you do not do this,
the course steered will be different from that
displayed.
T e AP46 autopilot will select t e position of t e rudder w en
AUTO is selected as t e position of t e rudder to allow t e vessel
to steer straig t a ead. T is can be an advantage in most vessels
w en a slig t amount of elm from t e p ysical centre position is
required for t e vessel to go straig t.
GPS Mode
For use w en interfaced to a GPS or plotting system generating NMEA
0183 data output in t e correct sentence format. GPS mode allows t e
autopilot to be directed by t e GPS, enabling automatic eading c anges
and eliminating t e effects of wind and tide.
T e digital display indicates t e course-to-steer, w ic will be t e
bearing between t e origin and destination waypoints, plus a factor to
correct for t e current cross track error (XTE).
