9.12 Adjusting the stabilisation sensor offset
Independent of the hull unit orientation, the offset of the
stabilization sensor is always defined as:
• the angle measured clockwise from the 0 degrees transducer
mark to the 0 degrees reference for the stabilization sensor.
The 0 degrees transducer mark is located outermost on the
mounting flange. The 0 degrees reference for the stabilization
sensor is always related to the gantry, as indicated in the figure
below.

Offset angle
Procedure: To estimate the offset angle
Observe the following procedure to estimate the offset of the
stabilization sensor.
5 Locate the 0 degrees transducer mark.
6 Estimate the approximate offset angle (0 to 360 degrees)
clockwise from the 0 degrees transducer mark to the 0
degrees reference stabilization mark.
- The angle between each mounting bolt can be used as
an aid.
- 20 bolts version: 18 degrees between each bolt.
- 24 bolts version: 15 degrees between each bolt.
7 Record the estimated offset angle.
