52 The GS550 System
Programming the GS550 for List and Trim Indication
For list indication, add the GS010-03 id number to the sensor list (menu 4A1) and select the sensor
type “List sensor”.
For trim indication, add the GS010-03 id number to the sensor list (menu 4A1) and select the
sensor type “Trim sensor”.
The maximum and minimum angles for list and trim indication can be adjusted in the limit menu.
The default limits are 10.0° maximum and -10.0° minimum.
Mounting Instructions
W
ARNING
! Remove the angle sensor from any connecting metal structures or surfaces
when welding the metal lugs to the mounting surface. Proximity to welding may cause
permanent damage to the angle sensor and prevent accurate angle indication.
1. Determine the angle sensor position.
a. The mounting surface must be flat and known to be level (0°) in both the list and trim
axes.
b. The angle sensor must have a clear line of sight to the cabin mounted display.
c. The angle sensor must be installed horizontally, with the antenna pointing up.
d. The list and trim axes are indicated on the angle sensor, follow these indications to ori-
ent the sensor correctly for accurate list and trim indication.
e. The angle sensor antenna must not contact a metal object.
2. Install the welding pads; keep the angle sensor well removed from the weld site and any
connecting metal objects while welding.
3. Mount the angle sensor to the weld pads with the screws and washers provided.
4. Verify list and trim angle indication by the GS550; in operation display, use Next to advance to
the list and trim indication page.
List and Trim Angle Calibration Procedure
Calibrate angle indication by adjusting the offset values for list and trim in the GS550 display; the
GS550 will then communicate the updated offset values to the sensor.
1. Install the sensor at a precisely known list and trim angle.
2. Press Menu → Next → Next → Next to go to 4) Installation.
3. Press Enter → Next to go to 4B) Sensor Calibration.
4. Press Enter to go to the password page.
5. Use Back, Next, Up and Down to enter the user password, and then press Enter to go to 4B1)
Automatic value calibration wizard.
6. Press Enter to go to page 4B1A)
