Context
The Power Supply Unit is mounted on the bulkhead close to the hull unit. The purpose of the Power Supply Unit is to provide the hull unit with the necessary power for operation. The Power Supply Unit further contains the logic circuitry required to control the lower and hoist operation, as well as a
small motion sensor.
If the Power Supply Unit has been mounted with its door pointing straight aft, you do not need to enter any rotation values. If the unit faces in any other direction you must compensate for this by typing the relevant value for Rotation Around Z.
Independent of the power supply 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.
Rotation Around Z:
|
A |
Unit facing aft: 0 degrees |
|
B |
Unit facing port: +90 degrees |
|
C |
Unit facing forward: ±180 degrees |
|
D |
Unit facing starboard: -90 degrees |
NoteDo not confuse stabilization offset with installation offset. The installation offset values describe the physical location and orientation
of an item, and how this location is related to the vessel's
coordinate system. The stabilization offset values describe any misalignments related to the measurements a sensor make.
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. |
