Prerequisites
The CS90 is installed as specified in this manual.
|
• |
The CS90 is turned on, and it is working normally. |
|
• |
The CS90 is in Normal mode, but TX Power is set to Off to prevent transmission. |
|
• |
The transducer is retracted to its upper position. |
|
• |
The vessel is berthed or at sea. |
Neither tools nor instruments are required.
CautionYou must never set the CS90 to "ping" unless the transducer is submerged in water. The transducer may be damaged if it transmits in open air.

This is the alignment angle. |
For accurate location of the transducer, you need the detailed vessel drawings. You also need the alignment angle that was recorded when the hull unit was installed.
Context
As a general recommendation, the hull unit shall be oriented with the hoist/lower motor pointing aft. If this orientation makes it difficult to access the Motor Control Unit, 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. |
|
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. |
