This distance is measured from the centre of the magnetic system of the compass to the nearest
point on the corresponding unit concerned.
-
Units which are to be used on the bridge wing must be installed inside the "wing control console" -
protected against the weather - if they do not at least correspond to the enclosure type IP 56. In
order to avoid misting of the viewing screen, 25 ... 50 W console-heating (power depending on the
volume) is recommended.
-
When selecting the site of a unit, the maximum cable lengths have to be considered according to
the notes in the cabling documents (remarks, cable list).
-
The accessibility for maintenance and service (stated in the outline drawings or installation draw-
ings) must be considered.
-
The impairment of a digital read-out or a display screen by direct light from lamps or the sun must
be avoided. Rear windows must be blacked out by means of roller blinds or Venetian blinds.
-
Disturbing reflections on the screen of a display caused by pilot lamps and illuminated signs must
be prevented by suitable measures (screening or relocating).
-
When a unit is being installed, the base, floor or bulkhead must be checked to ensure that it is
flat in order to avoid twisting of the unit when the fixing screws are tightened, because such twisting
would impair mechanical functions. Any unevenness should be compensated for by means of
spacing-washers.
-
The grounding screws of the units must be connected to the body of the ship (ground); the wire
used should have a cross sectional area of at least 6 mm.
Aboard fibreglass (GRP) vessels, a "grounding network" with a high conductance - taking into
consideration the working frequencies of the other equipment - must be provided in order to achieve
satisfactory EMC (electromagnetic compatibility).
-
In the interests of safety during maintaining or servicing, the shipyard should provide a common
isolating switch or circuit breaker (in conjunction with a contactor, if necessary) for all intercon-
nected equipment.
-
Transportation damage, even if apparently insignificant at first glance, must immediately be exam-
ined and be reported to the freight carrier. The moment of setting-to-work of the equipment is too
late, not only for reporting the damage but also for the supply of replacements.
-
The equipment should never be switched on by the electricians who did the installation work
- not even just for a moment - never!
This is a job for the authorised SAM Electronics service engineer.
-
After hand-over of the equipment in good operating condition to the customer, the Installation
Report (Annex of the Warranty Certificate) should be filled in completely and then forwarded to SAM
Electronics, Hamburg, as proof of such fulfilment. It is important that these requirements be fulfilled
in order to avoid the risk of losing the warranty.
