Step 1. Determine the angle sensor position.
a. The GS010-01 boom angle sensor can be mounted on either side of the boom.
b. The GS010-02 360° angle sensor must be mounted on the left side of the jib.
c. The angle sensor must be level with the boom centreline.
d. The top / bottom axis of the angle sensor must be within 15 degrees of vertical
e. The angle sensor must have a clear line of sight to the cabin mounted display.
f. The angle sensor antenna must not contact a metal object.
Step 2. Install the welding pads; keep the angle sensor well removed from the weld site and
any connecting metal objects while welding.
Step 3. Mount the angle sensor to the weld pads with the screws and washers provided.
Step 4. Verify angle indication on the GS550 LCD.
Step 5. If the angle displayed by a GS010-01 boom angle sensor is a high negative value, then
tilt the angle sensor up over 45 degrees, and then tilt back down to horizontal. The
GS010-01 boom angle sensor will automatically detect on which side of the boom it is
installed and correct angle indication accordingly.
Tip: To enable crane functions when alarm conditions are present, press Bypass for 10 seconds to
enter the “Rig Mode”. Press Bypass once to exit.
Angle Calibration Procedure 1: Mechanical Set-Up
Step 1. Level the boom such that it is perfectly horizontal; use a high quality bubble or digital
angle sensor. Verify the GS550 display indicates 0.0 degrees.
If not then:
Step 2. (GS011 angle/length sensor only) Carefully remove the cover of the LS101 cable reel.
Step 3. Loosen the mounting screw in the slotted hole of the angle sensor mounting plate.
Step 4. Pivot the angle sensor slightly until angle indication is correct.
Tip: When the angle sensor is moved very slowly, it may take several seconds to see an update at
the GS550 display. Instead move the sensor up a couple of degrees, and then bring it back down
to where it should be. The small light on the angle sensor flashes when it transmits a new value to
the display.
