2. For GS011 angle/length sensors only: Carefully
remove the cover of the GS101 cable reel.
3. Loosen the mounting screw in the slotted hole
of the angle sensor mounting plate.
4. Pivot the angle sensor slightly until angle
indication is correct. Repeat the angle validation
(step 1) as required.
2.3c Angle Calibration Procedure
№ 2: Correct with the GS550
Calibrate angle indication by adjusting the trim (offset)
value in the GS550 display; the GS550 will then
communicate the updated trim value to the sensor.
1. Position the boom at a precisely known angle.
2. Go to 4B) SENSOR CALIBRATION and press Enter.
3. Enter the user password (using Back, Next, Up
and Down as described in Password settings
section) and press Enter.
4. Go to 4B2A)
5. Use Back and Next to select the angle sensor
to be calibrated.
6. Press Enter and then Next to go to the trim
adjustment page.
7. Use Up and Down to adjust the trim value.
Example: If angle indicated is 0.3° over the actual
angle, adjust the trim value to -0.3.
Example: If angle indicated is 0.9° below the actual
angle, adjust the trim value to 0.9.
8. Press Enter to save changes.
9. Press Exit four times to return to the operation
display.
10.Verify accurate angle indication at both very
high and very low angles.

Anti-Two-Block Switch
Anti-Two-Block Switch
Verify the anti-two-block switch is programmed to
the GS550 display. Switches shipped with displays
are pre-programmed in the factory. Test: if the
switch has been programmed to the display then
the display will go into two-block alarm when the
switch is released. Press Bypass to silence the
alarm until the next two-block event or simulation.
If the switch has not been programmed to the
display, this should be done before proceeding with
installation. See the section How to Add a Sensor
to the GS550.

WARNING!
Keep the anti-two-block switch
away from the boom and any connecting
metal structures when welding mounting
brackets to the boom. Proximity to welding
may cause permanent damage to the anti-
two-block switch and render the anti-two-
block system unsafe.
!
!
IMPORTANT!
To ensure reliable radio
communication between the anti-two-block
switch and the GS550 display the following
conditions must be respected:
•The antenna of the anti-two-block switch
should not be in contact with metal.
•The anti-two-block switch antenna should
point to the left or to the right of the boom;
it should not point directly to, or away from,
the GS550 display.
•The anti-two-block switch antenna should
have a clear line of sight to the GS550
display; in most cases this means mounting
the sensor on the same side of the boom as
the operator's cab.
