2 of 34 TMQ Electronics - AP47C Autopilot
Warnings
• The autopilot is a navigational
aid; an adequate watch must
be maintained at all times when
autopilot is in use.
• The autopilot must be placed in
manual mode when the vessel
is stationary as the system may
continue to drive the rudder to the
end of its travel and damage to the
system may result.
• It is strongly recommended that
the autopilot not be used while
navigating in restricted waterways
as water currents, wind changes or
radio transmitter interference can
endanger your own or other vessels.
• It is recommended to install a
rudder feedback unit for best
performance; otherwise the system
will not operate in auto / gps mode
unless the vessel is moving at a
congurableminimumspeed.

Important Installation
Notes
• Access for wiring must be provided.
cables will possibly need to be
run or extended if required, to the
vessels switchboard, AP47C display,
e-compass, rudder feedback (if
tted)anddriveunit.
• AP47C cables and equipment must
be located as far as possible from
transmitting equipment and cables
(e.g. radio aerials and aerial cables,
radars, inverters, ect) to prevent
electro-magnetic-interference.
• The e-compass must be mounted a
minimum distance of 1 meter from
other magnetic compasses, radios,
speakers, transmitting equipment
or other products with magnetic
properties, to avoid interference.
• The AP47C must have a direct
connection to power supply via a
15 amp circuit breaker or a 15 amp
fused circuit and an isolating switch.

Installation
AP47C CDU Installation
Dimensions
AP47C CDU Installation Guide
- The AP47C Head unit should be
mounted in a position accessible to
the steering position and protected
from direct rain or salt water.
- For in dash mounting cut a 75mm
(3.0”) hole
- An optional mounting bracket
is available and may be used
for desktop mounting - see your
supplier
- Drill mounting screw holes
- Mount the display using screws
supplied (304 SS – 6G)
NOTE: Use the protection cover
when the system is not in use, to
protect the screen and casing from
UV and other physical damage
ELECOM
Electronic Compass
(E-Compass V.3)
Take care when handling the
compass as it is a sensitive piece of
equipment.
The compass position is the most
important item in the installation of
the autopilot. Good course holding
is dependent on the compass being
free from magnetic interference and
excessive rolling or pitching.
E-Compass Specications:
• Output based on NMEA 0183
standards
• Protocol Settings: 4800–8–N–1
• Output Sentences: HDM & ROT
• Power supply: 12-24 VDC <1Watt
• No moving parts to prevent
mechanical wear-out, small size and
high reliability.
110mm 43mm Mounting holes are at 94mm square
110mm

7 of 34TMQ Electronics - AP47C Autopilot
• Solid state electronics with tilt and
roll compensation up to 35degrees.
E-Compass Installation Guide:
• IMPORTANT! The compass must
bettedinanareaatleast1meter
away from steel objects.
• Avoid positions near radios,
speakers, aerials, antenna cables or
any other current carrying cables.
• Select a dry position free from
magnetic interference.
•Ifsystemisttedtoasteelhull
vessel, the compass must be
mounted at least 1m above the steel
structure on a non-magnetic post or
bracket (aluminium and wood are
good options in this case)
• A lower / aft mounted position along
the centre of the hull is preferred, to
reducetheinuenceofvesselroll
and pitch.
• Check other side of bulkheads and
deck heads for magnetic interfering
type objects before mounting.
• Mount the compass horizontally
with the arrow (bow) pointing to the
front of the vessel, preferably on a
stainless steel, wooden or plastic
bracket.
• Use non-magnetic screws to mount
the compass unit (316 grade
stainless steel)
•Theunitmustbemountedonaat
horizontal surface.
• Before selecting the E-compass
installation position, it is good to
test the installation position is free
from interference by checking the
location with a portable magnetic
compass.

Rudder Feedback Unit
Rudder Feedback Unit (RFUS)
The RFU is optional, although
recommended for the best possible
performance on some types of
vessels.
For example: A RFU must be
installed on vessels with high sides
that are sensitive to winds turning the
boat, or high powered 5-6m Deep V
(22-25 deg dead rise / 175HP+) type
vessels used in rough seas and high
winds. Or any other vessels that are
overly sensitive and very responsive
to small amounts of ‘rudder’ at high
speeds.
When the RFU is installed, the
congurationsettingsaresimplied.
Non-RFU mode is slightly more
complicated.
NOTE: The RFUS is factory aligned.
The arm should not be removed or
loosened. It is also water resistant,
however, if mounted in a wet position
some protection should be provided
to prevent water damage or physical
damage.
RFU Installation Guide
1. Refer to installation diagram and
installation template supplied with
the unit
2. Mount rudder feedback adjacent to
the tiller (NOTE: rudder feedback
movement must copy the angular
movement of the tiller like a
pendulum)
3. Use a mounting bracket if required.
4. Note the markings on the rudder
feedback unit. ‘P & S’ (Port and
Starboard) to check ruder moves
in the correct direction, manually,
before testing on the water.
5. Check installation is suitable
by slowly moving the steering
manually, to ensure:
a. The direction indicated on the
top of the RFU is correct
b. No undue mechanical strain
is placed on the feedback
or linkage. (Also check for
strain when the tiller is tilted
upright (for outboard engine
installations)
6. To complete the install, use
the AP47C advanced menu to
calibrate the rudder limits and
centre point of the RFU.

Motor Drive Concept
During AUTO or GPS modes, the system will pulse the drive motor when it
is close to the desired target heading. This allows the system to make minor
adjustments to the rudder to stay on course. Also note the dead band (relating
to the rudder sense setting) this accounts for excessive play in the rudder and
reducestherudder‘hunting’e󰀨ect.

To access the AP47C Settings menu
Press the MODE button.

To increase or decrease any AP47C settings press or
Continuously press MODE to scroll between each of the AP47C Settings, or

NOTE: Any modied setting will be automatically saved and stored in memory.

17 of 34TMQ Electronics - AP47C Autopilot
Pilot Settings Explained (RFU Mode)
RUDDER RATIO (Gain) Range: 1-40 Default: 15
Controlstheamountofdrive/rudderappliedforagiveno󰀨-courseangle.
In general, a vessel with fast turning rate will require a lower value.
This may be adjusted according to vessel speed. I.e. Low speeds may require
a higher value, as the vessel will respond slower to larger rudder movements
at lower speeds.
NOTE: If the vessel is understeering and taking a long time to get back on
track, increase this value. If the vessel is over-steering or overshooting and
making hard turns to stay on track, decrease this value.

18 of 34 TMQ Electronics - AP47C Autopilot
RUDDER SENSE (Sensitivity)
Range: 1-10 Default: 1
Theacceptableamountofo󰀨-courseerrorallowedforminorruddercorrections.
Increasing this value reduces the amount of pulses used to keep the
vessel on course.
If the vessels rudder is continuously hunting, always increase this value to avoid
damaging the drive unit.
This value should also be increased in poor weather conditions. For example,
when going up a wave the vessels course may move +6 degrees, on the way
down the vessel corrects itself -6 degrees naturally, therefore Rudder Sense
value should be increased. Otherwise, the AP47C will correct the course
change and drive the rudder on the way up the wave, in turn causing the vessel
to oversteer when moving down the wave, therefore resulting in excessive
unnecessary rudder corrections.
RATE OF TURN
Range: 10-720 (degrees/min) Default: 700
Limits the rudder drive when the AP47C detects the vessel is turning too fast.
I.e. if the rate of change in heading exceeds this value, the AP47C system
limits the rudder drive to limit high speed turns. If this setting is too low, the
vessel may understeer when changing course.
