Rudder offset adjustment
This procedure checks that the rudder reference transducer is correctly
aligned with the rudder. It is only required if a rudder reference
transducer is fitted.
To check and correct for rudder offset:
1. Move the helm to its centre position, using the
-1
,
+1
,
-10
and
+10
keys.
2. Check the rudder bar display. The rudder angle should be within ±
7∞ of centre.
3. To improve the alignment, slacken the rudder reference mounting
bolts and rotate the base until the reported rudder angle is as close
to zero as possible. Then tighten the bolts again.
4. Fine adjustment, to align the display and helm accurately, is
achieved using the Rudder Offset option in Dealer Setup (see
Chapter 5 ). However, this cannot be used to correct an offset of
more than ± 7∞.
