Because of the vast number of different manufacturers and

models of navigational equipment, Simrad cannot guarantee

correct operation and installation of this equipment. Therefore,

before connecting any equipment to the Wheelpilot, it is

important that the unit’s manual is referred to with regard to

interfacing via NMEA.

5.5 Electronic interference suppression

The Wheelpilot has been designed to minimise 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.

5.6 Auto compass calibration

Once the Wheelpilot 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 Wheelpilot in Standby mode, press the Starboard key a

number of times to induce a slow clockwise rotation of the ves-

sel. Press and hold the TACK key, followed by the Port ( ) and

Starboard ( ) keys simultaneously (Fig 5.15) -

The Port and Starboard LEDs will both light. Allow the vessel

to turn through a minimum of 1

/4 turns (450º) in approximate-

ly two minutes, during which time the fluxgate compass will

automatically calibrate itself.
