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.
|
B |
This is the offset angle. |
|
D |
0° motion sensor reference |
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. The 0° reference for the built-in sensor is always related to the gantry. If the hoist/lower motor does not point aft (on or parallel to the vessel’s centre line) the built-in motion sensor offset must be defined. Independent of the hull unit orientation, the offset of the built-in motion sensor is always defined as:
The angle measured from the bow to the motion sensor’s 0° reference.
TipFor improved operational accuracy, an external motion reference unit (MRU) may be used.
On the MRU page, define the offset as rotation around Z.
|
• |
If the 0° reference mark for the built-in motion sensor points to the starboard (right) side of the vessel’s centre line (as
shown in the illustration), insert the offset as a number between 0 and +180 degrees. |
|
• |
If the 0° reference mark points to the port (left) side of the vessel’s centre line, insert the offset 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. |
|
D |
Reference point (Ship Origin) |
