Operational Information
There are two very important criteria that must be observed when working
with the cone-up sensor.
1. The magnetic flux unit and the sensor must be correctly orientated
to ensure correct operation. The two large spots on the magnetic
flux unit must be orientated vertically (in line with the cone-rod). On
the back of the sensor is a small location-marking slot. This must be
positioned in line with the magnetic flux unit’s black markers.
2. The distance between the magnetic flux unit and the sensor is very
critical. It must be between approximately 30mm, symmetrically
positioned about the cone-rod.
Maintenance
NOTE:
Appropriate safe working practices should be followed to ensure that
all hazards are minimised.
When the system is in operation, the cone-up sensor 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 housings,
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 positioning and orientation of the sensors should be checked on a regular
basis. It is also necessary to ensure the lock nuts are tight.
The electrical cable connected to the cone-up sensor 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.
