2.1.2 CONTROL UNITS
Both the indicating and non indicating control
units are designed for surface mounting in any
position. Both are non magnetic and may be
positioned near a steering compass if necessary.
In all cases the control units should be placed
within easy reach and view of the helmsman. As a
general rule, the non indicating control unit would
be most suitable for cockpit installation adjacent
to the helmsman. A non indicating control unit
may also be specified for the second steering
position in the flying bridge of a power vessel. The
indicating control unit is equally watertight and
can be mounted externally if preferred. An
indicating control unit can also be useful at the
navigation table where course information is
visible and course changes can be made directly
by the navigator.
A printed template is provided to assist
marking out fixing hole positions and locating the
20mm dia. drilled hole for the interconnecting
cable. After threading the interconnecting cable
through the 20mm dia. hole, the control unit is
finally screwed into position using the four self
tapping screws provided (Fig.
blanking
plugs are supplied to conceal the fixing screw
recesses in the
and these should be firmly
pressed into position to complete the installation.
The deck socket for the hand-held control unit
should be situated in a reasonably protected
position. Normally, the remote control socket will
be mounted in the cockpit area or anywhere that
a remote control facility may be required.
The remote control socket is supplied as
standard with a plug attached to the
interconnecting cable at the opposite end to
the deck socket. For use with the
6000 the plug
(not the deck socket)
should
but cut off the cable which should be passed
through a 22mm dia. hole bored through the
mounting panel. The socket is then screwed
into position using the four self tapping screws
provided (Fig. 6).
Interconnecting cables from all control units
should be led back to the connector unit of the
course computer for connection to the common
control unit bus (see section 2.3.1).
