20 ST60+ Compass Instrument Owner’s Handbook
If you are not sure of the magnetic suitability of the chosen location, carry out a
survey of the site as follows:
1. Temporarily fix a simple hand bearing compass at the intended location.
2. Swing the vessel through 360° while at the same time observing differences
between the hand bearing compass and the vessel's main steering compass.
3. If there are no differences, greater than 10° on any heading, then the site is
suitable for the Fluxgate Compass transducer.
Using the self-tapping screws provided, mount the Fluxgate Compass transducer
vertically on a suitable bulkhead, so that the connecting cable is downmost.
Running transducer cable
General
The manner in which you run the cable from the Fluxgate Compass transducer will
depend on the locations of the transducer and instrument. The following
guidelines are provided:
• If the cable has to be fed through the deck, always use a proprietary deck
gland.
• Where cables are fed through holes, always use grommets to prevent chafing.
• Secure long cable runs so they do not present a hazard.
• Although the transducer cable is fitted with spade connectors for direct con-
nection to the rear of the instrument, it may be necessary to remove these to
facilitate installation e.g. if you want incorporate a junction box in the cable
run or if the cable has to be routed through narrow apertures. Extra spade
connectors are provided, to replace any that are removed when running the
cable. When fitting spade connectors, prepare the cable as at (a) in the follow-
ing illustration, then fold back the wire strands and insert into the spade con-
nector as at (b). Ensure the wire strands do not extend beyond the rear of the
spade connector insulation, then crimp the connector to the wire.
