WSP-038 IMU INSTALLATION MANUAL
WSP-038 IMU INSTALLATION MANUAL
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.
6.
Run the
WSP-038 CONFIG SW
.
If the WSP-038 Config SW does not automatically connect, follow steps below:
»
Select the
SET PC COMMUNICATION
Tab.
»
Click
USE ETHERNET FOR COMMUNICATION
»
Click
NETWORK SCAN
and you will see the WSP-038 IP 172.16.1.100, click to
connect.
»
Select
USE SELECTED
then
SAVE CHANGES
.
7.
In the WSP-038 Config SW,
SETUP
,
SERIAL PROTOCOL
and
SERIAL INPUT
should
be checked to confirm data.
Contact WASSP Support or your local dealer for support or WSP-038 diagnosing issues.
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
positive.
»
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
settings to match
the measurement
of the sensor
to the centre of
gravity. Especially
useful is the Z
coordinate.
Press the
SET
button to send
the configuration
settings to the
unit.
