Context
As a general recommendation, the hull unit shall be oriented with the hoisting motor pointing aft. If this orientation makes it difficult to access electrical connections, the hull unit may be rotated during its installation
to the most suitable direction. Independent of the hull unit orientation, the alignment is always defined as:
The angle measured from the bow to the 0° transducer mark.
The 0° transducer mark is located outermost on the mounting flange, and it is marked as a red "0". Depending on the transducer mounting, it can be located at any angle on the mounting flange, not necessarily as shown in the
illustration.
On the Transducer page, define this angle as rotation around Z.

If the 0° transducer mark points to the starboard (right) side of the vessel’s centre line, insert the alignment as a number
between 0 and +180 degrees. |
|
• |
If the 0° transducer mark points to the port (left) side of the vessel’s centre line (as shown in the illustration), insert
the alignment as a number between 0 and –180 degrees. |
Illustration:

A |
Rotation around the x-axis: In the positive horizontal direction (forward), a positive rotation is clockwise. |
|
B |
Rotation around the y-axis: In the positive horizontal direction (starboard), a positive rotation is clockwise. |
|
C |
Rotation around the z-axis: In the positive vertical direction (down), a positive rotation is clockwise. |
