Maintenance
NOTE:
Appropriate safe working practices should be followed to ensure that
all hazards are minimised.
When the system is in operation, the encoder 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 all the main housing,
gears, connector, and connecting cable.
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 encoder should be visually inspected to
ensure there are no chafes or cuts 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.
The gears and external magnetic coupling of the encoder should be sprayed
with light oil or WD40 to limit corrosion.
