Chapter 1: Basic Operation 7

To cancel an Off Course alarm, press

standby

to return to manual steering. If the

heading recovers or if you change course, the alarm clears automatically.

Note: The default off course angle is set at 20º. You can adjust this angle in Dealer Calibration

(see SmartPilot X-5R Drive Installation & Commissioning Guide).

1.4 Adjusting pilot performance

The principal method of adjusting the performance of an SPX-5R Drive system is by

changing the response level. This controls the relationship between the course

keeping accuracy of the SPX-5R Drive system, and the amount of helm/drive activity.

Changing the response level should be the only adjustment you need to make to your

SPX-5R Drive system on a regular basis.

When you first turn on your SPX-5 Drive system after installation, the response will

initially be set to the default level of 5, but you can change this level in User Calibration

(refer to your SmartPilot X-5R Drive Installation & Setup Guide for details). Changes

made using user Calibration will be retained when the SPX-5R Drive system is

switched off.

You can also make temporary adjustments to the response level 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.

The SPX-5R Drive system has nine levels of response:

• Levels 9 to 7 give the tightest course keeping and greatest rudder activity (and

power consumption). This can lead to a rough passage in open waters as the

SPX-5R Pilot may ‘fight’ the sea.

• Levels 6 to 4 should give good course keeping with crisp, well controlled turns

under normal operating conditions.

• Levels 3 to 1 minimize the amount of pilot activity. This conserves power, but may

compromise short-term course-keeping accuracy.
