Check the sensor outputs screen retracted and extended lengths. Retracted length should be correct
at 0500mV and extended boom length will depend on the model.
Extended main boom , millivolts
17.4 CALIBRATE ANGLE INPUT
The angle sensor is calibrated at four different reference angles of approximately 0°, 40°, 60°, and
70°. The “BOOM T” specifies the calibration angle the boom should be moved to. When “CHANG” is
displayed by the actual boom angle, the boom angle maybe calibrated. The previously calibrated
angles define the reference angles.
NOTE: This process should be repeated if sensor is ever removed or replaced.
Use and keys to mark the main boom angle calibration.
Press to activate angle calibration.-
To continue, press .
to calibrate, press
(BOOM T: is calibration angle, CHANG is actual angle) move
boom so the CHANGE angle is with in ±2° of the BOOM T angle.
to continue press . .
Mark CHANGE and press to change angle calibration.
Mark, OK if no change is necessary.
Use and keys to change angle to match the BOOM T
angle. Press to calibrate the main boom angle.
Move boom so the CHANGE angle is with in ±2° of the BOOM T
angle. to continue, press .
Mark CHANGE and press to change angle calibration.
Mark OK if no change is necessary.
