are tight. Either altimeter can be fitted on either end of the y-cable, as the
altimeters are addressed serially.
The mounting arm should only be tightened to the point where it holds the
position it is set to, but will move out the way if it is pushed. The sensors
must be fitted in a vertical orientation.
Maintenance
NOTE:
Appropriate safe working practices should be followed to ensure that
all hazards are minimised.
When the system is in operation, the altimeters should be washed down with
clean, salt-free water whenever it is returned to the deck of the ship. This will
reduce corrosion, and enable thorough inspection of the main sensor housings,
connectors, and connecting cables.
It is good working practice to regularly check all fastenings to ensure they are
present, tight, and there is no damage to them or the items they are fitted to.
Any damaged fastenings should be replaced immediately.
The electrical cable connected to the altimeters should be visually inspected to
ensure there are no chafes or cut in the insulation. The connectors on both
ends of the cable should be tightly fitted with no face gap, and the lock-rings
should be finger-tight. Any damaged cables or lock-rings should be replaced
immediately.
