Test run:
1.
Test runs must not be performed in constricted channels or waters with heavy traffic.
2.
Test runs should preferably be performed in average sea conditions.
3.
Fine adjustment of the individual functions during the test run should best be performed in the following
order:
a) Automatic compass compensation:
The compass compensation must be performed in accordance with the instruction manual before you
start the test run (see p. 43)
b) Setting the rudder factor:
If the vessel understeers (i.e. there is too little rudder correction), the rudder factor setting "Rud" must
be increased. If there is too much rudder action and the vessel oversteers, the rudder factor setting
"Rud" must be reduced.
c) Setting the counter rudder:
First set the counter rudder "C/R" to a value of 0. Turn the vessel at normal cruising speed through 90°
by pressing one of the "ARROW" keys. The counter rudder should be set in such a way that the vessel
turns approx. 10° beyond the new course before it swings back to it. If it runs across the new course
again, the counter rudder setting should be increased. If the vessel only approaches the new course
very slowly, the setting should be reduced. When this setting has been made, step b) should be
repeated.
d) Setting the trimming rate:
On single engined vessels or sailing yachts it is only possible to check the trimming setting "Trim" when
prevailing weather conditions cause the vessel to be steered with counter rudder. The best trim setting
for these vessel types can therefore be found on the basis of experience.
To check the trimming setting on vessels with twin engines, the vessel must be driven by both engines
in pilot mode. One engine is then to be throttled back. The vessel will initially deviate from the course,
but should return to it within less than 60 seconds. If it takes longer, the trimming setting must be
increased.
e) Setting the damping:
The damping setting "Damp" can be used to damp the compass signal. This is normally only necessary
on vessels on which the compass sensor is mounted high above deck (steel vessels with a sensor on
the mast). If the autopilot becomes overactive in bad weather, the damping should be increased.
When these test runs have been performed, the settings are stored in the microprocessor. It is recommended
to note the basic settings in the table on page 50, so that the correct settings can be restored after any
inadvertent changes.
The settings are only permanently stored in memory when the "Save" function is activated
(see p. 45).
