Chapter 6: Installation

6.1 Mechanical Installation

The NAVIGAT X MK 1 gyrocompass system comprises the compass
housing complete with installed base plate assembly and master PCB,
the gyrosphere container, the gyrosphere and the installation and
replacement parts kit.

The gyrosphere is contained in a carrying box, which is packed in a
transport container. This transport container is completely suitable for
transport by air, sea, rail and road.

Until installation, the carrying box containing the gyrosphere is to be
stored in its original transport container. Upon installation, the carrying
box with the gyrosphere is to be removed from the transport container
and is to be carried by hand directly to the place of installation.

Installing the Compass Housing

The compass housing is to be attached to a level surface, e.g. a floor or
console base by means of six M10 bolts or welding studs (to be supplied
by the shipyard). At the location of the compass, proper ventilation must
be ensured and sufficient space provided for the housing to be opened
and maintenance work to be carried out.

For the amount of space required, the attachment points and the posi-
tion of the cable inlets, refer to dimension drawing 4914-0112-02.

In the horizontal plane, the compass may be installed at any angle with
respect to the vessel‘s longitudinal axis.
Alignment error (i.e. the angle between the compass‘ and the vessel‘s
longitudinal axis) is corrected electronically by setting the alignment
error correction value in the Service Setup 1.

CAUTION

The gyrosphere is always to be transported in its carrying box in the orig-
inal transport container.
Do not throw or drop the transport container.
The transport container is to be transported in an upright position only.

CAUTION

Carry the carrying box containing the gyrosphere by hand only and han-
dle it with extreme care. Remove the gyroshpere from the carrying box
only if required for immediate installation.
