UPPER HELM STATION
COMPENSATING LINE
AUTOPILOT DETAIL
a) A compensating line is required
between helm stations or the
helm and autopilot power pack.
b) All hoses should be routed with
a gradual rise (par ticularly the
compensating line) so that air
will not be trapped in the lower
helm station.
c) The second helm station or
autopilot power pack may be
connected at any location
between the upper helm station
and the cylinder. For existing
single station installations the
nylon or copper tubing may be
cut and the tee fittings installed
at any convenient location.
NOTICE
1) Most SeaStar Helm pumps have a built in check valve. Full
feedback helm pumps do not have a built in check valve and
one will be required for the installation of an autopilot, refer to
page 9-4 of this guide to determine whether your helm pump
has check valves built in.
2) Autopilot mfg. requires the volume of your steering cylinder(s) to
provide an adequate autopilot pump, refer to page 12-2 for
volumes of your cylinder.requirement.
Required details for the
addition of an autopilot.
