Off Course alarm
If you have been off course from the locked heading for longer than 20 seconds, an
alarm sounds and the Pilot Controller shows whether the deviation is to port or
starboard.
To cancel an Off Course alarm, press
standby
to return to manual steering. The
alarm clears automatically if the heading recovers or if you change course.
If an Off course Alarm occurs, ensure your boat is not carrying too much sail, and that
the sails are well balanced. You can usually significantly improve course keeping by
improving the sail balance.
Note:
The default off course angle is set at 20º. You can adjust this angle in Dealer Calibration
(see Commissioning Guide).
1.4 Adjusting pilot performance
The principal method of adjusting the performance of an SPX-5 Tiller system is by
changing the response level.The response level controls the relationship between
the course keeping accuracy of the SPX-5 Tiller system, and the amount of helm/
drive activity.
Changing the response level should be the only adjustment you need to make to your
SPX-5 Tiller system on a regular basis.
When you first turn on your SPX-5 Tiller system after installation, the response will
initially be set to the default level, but you can change this level in User Calibration
(refer to your
SmartPilot X-5 Tiller & GP Tiller Installation & Setup Guide
for details).
Changes made using user Calibration will be retained when the SPX-5 Tiller system
is switched off.
You can also make temporary adjustments to the response level when using your
SPX-5 Tiller system on a day-to-day basis, to quickly match performance to changing
conditions. Note however that these temporary changes to response level will be lost
when the system is powered off, with the default value being reapplied when the
system is next switched on.
Response levels
As a general rule, higher response values give tighter course keeping (e.g. for
pilotage in confined and sheltered waters). Lower values reduce drive activity and
conserve battery power.
