Context
MF90
The hull unit is fitted with a
label that indicates the forward
(bow) direction. This places the
0° transducer mark at an angle of
approximately 120 degrees on the
port side relative to the bow.
MF94
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. 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.
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.
