Adjusting performance – Types 150/400 and 100/300
To adjust the performance of Type 150/400 (non-GyroPlus) and
Type 100/300 autopilot systems you can change the response level.
Response level – Types 150/400 and 100/300
The response level controls the relationship between the autopilot’s
course keeping accuracy and the amount of helm/drive activity.
You can adjust the default response level in either User or Dealer
Calibration (see page 89). This determines the default power-up
response level.
However, when using your autopilot on a day-to-day basis, you will
need to make temporary adjustments to the response level. By doing
this you can match autopilot performance to different conditions.
Type 150/400 (without GyroPlus) and Type 100/300 autopilot
systems have three different response levels:
• Response Level 1: AutoSeastate on (Automatic deadband)
This setting causes the autopilot to gradually ignore repetitive
boat movements and only react to true variations in course. This
provides the best compromise between power consumption and
course keeping accuracy, and is the default calibration setting.
• Response Level 2: AutoSeastate off (Minimum deadband)
This setting provides tighter course keeping. However, this
results in increased power consumption and drive unit activity.
• Response Level 3: AutoSeastate off + yaw damping
This setting provides the tightest possible course keeping by
introducing counter rudder yaw damping. You can adjust the
counter rudder setting in Dealer Calibration (see page 95)
To make a temporary change to the response setting:
1. Display the
RESPONSE
screen by pressing either the
resp
key or
the
-1
and
+1
keys together momentarily.
2. Press
-1
or
+1
or the up arrow or down arrow keys to change the
response between levels 1 to 3.
3. Press
disp
or wait for 5 seconds to return to the previous display.
Note: You will lose these temporary changes to response level
whenever the system is powered off. You can make permanent
adjustments in User or Dealer Calibration (see page 89).
