h1000 compass unit
description
The h1000 compass is an electronic fluxgate for use with all h1000 systems. The unit is housed in a
sealed casing constructed of high impact plastic. It is therefore suitable for on or below deck mounting.
If installed in a vessel with a steel or reinforced concrete hull it may be necessary to install the
compass unit outside the magnetic screening affect of the hull and super-structure.
Two Fastnet² connectors are provided at the base of the unit. These connectors allow connection to the
rest of the system for the supply of power and data.
siting the compass unit
Mount the compass upright on a flat vertical bulkhead where it will be:
x
A safe distance from external magnetic interference:
3m (10ft) from VHF, RDF, loudspeakers, depth sounders, engines, or power cables carrying
heavy current.
x 3m (10ft) from radar and SSB equipment.
x Externally mounted on steel vessels.
x Protected from physical damage.
x Protected from water ingress (particularly bilge water).
x Optimum positioning: as low as possible to minimise effect of pitching and rolling of boat.
mounting procedure
x Secure the unit in the selected site using the non-magnetic self-tapping screws provided.
x Route the Fastnet 2 cable to the rest of the system avoiding other cables carrying heavy currents,
e.g. engine starter, trim-tabs, etc.
x Secure cables in place with cable clips or tie-wraps.
x Avoid bending the cable through a tight radius, especially near the connector as this may damage
the wires inside the cable.
