5.6 Installing the Sensitive elements
The Sensitive elements are shipped from the factory packed
separately, and the elements have to be installed in the Master
compasses according to the description below.
Note! A special tool (Simrad part no. 44174449) is required when
installing the Sensitive element. This tool is delivered together
with the gyro, and the sensitive element should not be installed
without using this tool.
Caution! Use extreme caution when handling the Sensitive element! Do
not tilt the element. It is filled with oil and the top includes a
ventilation opening.
1 Make sure that the master compasses are installed and
cables connect according to the description on page 45
onwards.
2 Remove the four screws on the Horizontal ring.
3 Lift the sensitive element carefully from its package, and
remove the rubber tube on top of the element.
Note! The package and the rubber tube should be kept for re-use if the
Sensitive element has to be sent to factory for service!
4 Tilt the Horizontal ring to the side where the plug is located,
and carefully put the sensitive element into the ring.
- The socket on the Sensitive element should be located
right above the plug attached to the Horizontal ring.
5 Position the Sensitive element on the Horizontal ring by
putting the assembly jigs into the holes as indicated on the
figure below. Observe the labelling and the diameter on
the jigs. Fasten two screws in the other two holes.
