APPENDIX A.4 LEVER ARM CONFIGURATION
ENTERING OFFSET MEASUREMENT IN THE WASSP SYSTEM DRX AND
WSP-038
Measurements In WASSP DRX to be entered via Commissioning
Application:
»
If the sensor is located aft of the reference point the X measurement is negative.
»
If the sensor is located to port of the reference point the Y measurement is negative.
»
If the sensor is located above the reference point the Z measurement is negative.
Measurements in WSP-038 Motion sensor to be entered via Sensor direct
Ethernet Connection:
If the motion sensor is located a significant distance from the Centre of Gravity, for
example mounted on the bridge of a large vessel, it is possible to enter an offset to
reduce acceleration errors. If the motion sensor is located high on a large vessel the
most significant factor will be the Z measurement.
Important note
for leaver arm settings in the WSP-038:
»
If the motion sensor is located aft of the COG the X measurement is
»
If the motion sensor is located to port of the COG the Y measurement is negative.
»
If the motion sensor is located above the COG the Z measurement is negative.

Set the Lever Arm

the measurement
of the sensor
to the centre of
gravity. Especially
useful is the Z
coordinate.

The lever arm is used to compensate for rotational accelerations. For example, if you
have a vessel where the motion sensor is located on the bridge with a Z distance from
the rotational point of the vessel that has large roll motion. The lever arm would then
calculate the lateral accelerations generated from the rotation acceleration and remove
this factor from its calculations which improves the angle output during these conditions.
The longer the distance is from the center of rotation the bigger the effect is mainly on
fast motions so the roll is normally the main parameter.
NOTE: DO NOT USE REMOTE HEAVE settings as this could lead to double
accounting of ship offsets.
