CONTROL UNIT
The conlrol unit slols into a permanently
mounled socket sited in the cockpit II
contains a gimballed fluxgale compass
and Iherefore has some
reslriclions
on
mounling posilion.
The control unit should be siled where
it
can be operated easily
horn
Ihe
steering positron. It should also be
posilioned al
leas1
60cm (2’6”) away
lrom
lhe
main steering compass lo avoid
devialion of both compasses.
Deviation of the control unit
fluxgale
compass is less imporlanl since
headings are always adjusted by
reference lo the main sleering compass.
Nevertheless, deviation should be
avoided if possible and thus the conlrol
unit should be siled as far away from
other
magnelic
or iron devices as
praclical.
Having selected the besl mounling
site, the mounling sockel may be
secured lo a convenient wooden or glass
libre surface using the self lapping
screws provided. The mounling surface
may slope away from verlical by a
maximum of 459
Battery Connection
The waterprool ‘Dri-Plug’ srrpplied
should be
silualetl
as close as possible lo
Ihe
Aulohelm 2000 lo minimise lead
length. The Dri-Plug sockel musl be
connecled
directly lo
the vessels
electrical dislribulion panel and on no
account paralleled into exisling wiring for
other equipment.
The Aulohelm supply must be
independently switched and
protecled
by a 5 amp fuse or current trip.
Since the autopilot is microprocessor
based
il
is very imporlant lhat vollage
losses in supply cables are minimised.
Supply cables sl~oulcl Iherelore he as
