Tillerpilots TP10/TP22/TP32

E04818 Issue 1.0
Because of the vast number of different manufacturers and
models of navigational equipment, Simrad cannot guarantee
correct operation and installation of third party equipment.
Therefore, before connecting any equipment to the Tillerpilot it
is important that the unit’s manual is referred to with regard to
interfacing via NMEA.
5.6 Electronic interference suppression
The Tillerpilot has been designed to minimize the effects of
interference generated by the engine alternator. However, pre-
cautions should still be taken by routing the cables away from
the engine compartment. Do not run the cables down trunking
carrying high current or radio antenna cables.
Engines with spark ignition, also some refrigerators, should be
fitted with suppressors. Your local agent should be able to
advise on this and supply suppression kits where necessary.
5.7 Auto compass calibration
Once the Tillerpilot is installed, it is necessary to calibrate the
internal compass to compensate for deviation caused by any
metallic or magnetic objects surrounding it on the vessel.
With the vessel motoring slowly (2–3 knots) in calm conditions
and the Tillerpilot in Standby mode, press the Starboard ( )
key a number of times to induce a slow, clockwise rotation of
the vessel. Then press and hold the TACK key, followed by the
Port ( ) and Starboard ( ) keys simultaneously (Fig 5.13).
The Port and Starboard LEDs will both light. Allow the vessel
to turn through a minimum of 1
1
/4 turns (450º) in approximate-
ly two minutes, during which time the fluxgate compass will
automatically calibrate itself.
If the rate of turn or boat speed is too fast, the Port LED will
flash (Fig 5.14). Either slow the boat, or reduce the angle of
turn. If the rate of turn or boat speed is too slow, the Starboard
LED will flash – either increase the boat speed, or increase the
angle of turn. A short beep will indicate that the calibration has
been successful and the Tillerpilot will return to Standby mode.
If the calibration has been unsuccessful, after a period of four
minutes a long beep will sound.
Note If the calibration routine keeps failing after repeated attempts,
the Tillerpilot may be experiencing excessive magnetic devia-
tion that it cannot compensate for. Check the area within 1 m
(3 ft) of the Tillerpilot for likely sources, such as cockpit speak-
ers or large metallic objects – if these cannot be relocated, it
may be necessary to fit an external compass (cf. section 3.3).
