Chapter 1: SmartPilot Operation 7
The response level controls the relationship between the SmartPilot’s course
keeping accuracy and the amount of helm/drive activity. When you turn on your
SmartPilot it will always be at the default level. (This level can be adjusted in User
Calibration
see page 24)
When you require extra tight course keeping (e.g. for pilotage in confined and
sheltered waters), increase the setting. If you want to minimize drive activity and
conserve battery power, decrease the setting.
You can make temporary adjustments to the response level when using your
SmartPilot on a day-to-day basis. By doing this you can match performance to
conditions as they occur.
Note:
You will lose these temporary changes to response level whenever the system is
powered off. You can make permanent adjustments in User Calibration (See page 24). This
determines the default power-up response level.
Adjusting performance – S1G, S2G and S3G systems
S1G, S2G and S3G systems have 9 levels of response:
level 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 SmartPilot may ‘fight’ the sea.
levels 6 to 4 should give good course keeping with crisp, well controlled
turns under normal operating conditions.
level 3 to 1 minimizes the amount of pilot activity. This conserves power, but
may compromise short-term course-keeping accuracy.
With these points in mind, you should use the following procedure to make
temporary adjustments to the response level when required:
1. Display the RESPONSE screen by pressingeither the
resp button or the -1
and
+1 buttons together momentarily.
Note:
The
RESPONSE
screen is set as a default data page (see SmartPilot Commis-
sioning Guide) so you can also access it by pressing
disp
and then scrolling through the
data pages.
2. Press -1 or +1or the up or down arrow buttons to change the response level.
