6.2 Troubleshooting
These simple checks should be carried out before seeking tech-
nical assistance and may save time and expense. Before con-
tacting your servicing agent, please note the Tillerpilot’s serial
number.
Symptom
When engaged, the pilot
immediately applies a large
helm angle and increases
course error.
After functioning normally
course is suddenly lost and the
Tillerpilot goes into Standby
Mode.
Helm is hard over and alarm is
continuously on.
Power socket is live, but pilot
is not on.
Loss of course under Steer To
Wind Mode.
Cannot select Steer To Wind
Mode.
Cannot select Nav Mode.
Autotack function not
working.
Pilot exits Nav Mode before
waypoint is reached.
Pilot does not hold accurate
course in Auto Mode.
Probable Cause
•Tillerpilot is configured for Port
hand setting but installed on
Starboard side (or vice versa).
• Power interrupted briefly, or low
voltage.
• Cable used to socket too small.
• Intermittent connection.
• Steerage way insufficient to control
course, or sails are aback. Pulsing is
a correct safety feature when tiller is

• Masthead unit is not connected.
• SimNet system is not switched on
or powered.

transmitted.
• GPS/Chart Plotter not connected.
• Waypoint not active.
• Wrong NMEA format is being used.
• Pilot is in Nav Mode.
• Pilot is in Steer To Wind Mode and
a) apparent wind is >90º
b) autotack being attempted is in
the wrong direction.
• Cross Track Error has exceeded 1.2
Nm.
• Fluxgate compass is being affected
by interference from nearby
magnetic influences (binnacle
compass, speakers) or metallic
objects (winches, deck hardware etc).

wind is less than 90º.
• Reset the vessel on course
and re-engage Nav Mode.
• Check compass has been
calibrated (section 5.6).
