5 Insert the relevant offset values.
a : Insert the horizontal distance on the x-axis (fore-and-aft direction)
X Offset
between the transducer and the Ship Origin.
b : Insert the horizontal distance on the y-axis (athwartship direction)
Y Offset
between the transducer and the Ship Origin.
c : Insert the vertical distance on the Z axis between the transducer
Z Offset
and the Ship Origin.
To do this you will need the ship drawings.
6 Obtain the alignment angle from the personnel that installed the hull unit.
a
Rotation Around X
deviation from the X axis (fore-and-aft direction) in the vessel coordinate
system. If the transducer is properly installed without unintentional skew, this
angle can be set to 0 degrees.
b
Rotation Around Y
deviation from the Y axis (athwartship direction) in the vessel coordinate
system. If the transducer is properly installed without unintentional skew, this
angle can be set to 0 degrees.
c
Rotation Around Z
deviation from the Z axis (vertical direction) in the vessel coordinate system.
This is the alignment angle.
• 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.
Examples:
• If the alignment angle is 295 degrees, insert -65 degrees.
• If the alignment angle is 15 degrees, insert 15 degrees.
Do this as accurately as possible.
