ComNav 1500 / 1510 Autopilot - 36 -
6.3.5 P4, Damping of wind [WSE]
Possible settings are [0] = Minimum to [9] = Maximum.
Default setting is [2].
Damping of wind transducer. The factory default setting
should be adequate. In very heavy weather or unstable
wind conditions, unnecessary corrections may be minimized
by increasing the setting.
6.3.6 P5 Automatic Trim Calibration [ATC]
Possible settings are [0] = Minimum to [9] = Maximum.
Set by the APC routine.
[ATC] is not critical. It constantly compares the course set against
the course steered and slowly applies more rudder as necessary to
reduce any errors to zero. Errors may be due to wind, waves or
other unbalanced forces such as single screw operation of a twin
screw boat, an off-center tow or weather helm on a sailing boat,
etc. If the trim time is set too high, it will take a long time to
eliminate the course error. If it is set too low it can start to degrade
course stability.
In general, longer trim times (higher settings) should be set for
large boats and sailing boats and shorter trim times (lower
settings) for small boats and high speed planning boats. The
factory default setting should be acceptable for all but extreme
applications.
6.3.7 P6, Adaptive Control [ADC]
Possible settings are [OFF] or [On].
This function is reserved for future functions.
6.3.8 P7, Automatic Pilot Calibration [APC]
Possible settings are [ON] or [OFF].
The APC routine automatically sets: [RUD], [SEA], [CRD], [ATC]
and [RRS].
The Autopilot will not function unless the boat pass the APC
routine. The APC will automatically determine and correct how
wires and pipes are connected. It will also learn how the boat
reacts on different rudder commands and automatically calibrate
itself.
To learn how to perform the APC function, see Sea Trials.
