Platform Controls
The platform control box contains the ALC600 platform Control Module. The platform Control Module receives all signals from the platform switches, joysticks and foot switch, and provides operator feedback through an Indicator Module. The joystick controllers at the platform controls utilize Hall Effect technology and require no calibration. Automatic calibration of center voltage occurs on power up if the signal value is in the valid range. Each joystick controller should operate smoothly and provide proportional speed control over its entire range of motion. The remaining boom functions operate by on/off toggle switches.

4-7 Primary Boom Angle Sensor
The primary boom angle sensor is used to limit the angle of the primary boom relative to the angle of the turntable and gravity.
How to Calibrate the Primary Boom Angle Sensor
Note: Perform this procedure with the machine on a firm, level surface with the boom in the stowed position.
Note: The turntable level sensor and platform load sensor must be calibrated prior to calibrating the primary boom angle sensor.
Note: This procedure will establish the cross-check angle with the boom limit switch LST3S. If LST3S does not switch its state properly during the calibration, the calibration will be invalidated.
1 Fully retract and lower the boom. Ensure the boom is in contact with the boom rest pad.
2 Enter Service Mode. Refer to Repair Procedure, How to Enter the Service Mode.
3 Press the settings button above the display and navigate to the Sensor Calibrations menu.

5 Select and start the calibration procedure.
6 Start the engine.
7 When the display prompts the operator to lower the boom, press and hold the function enable button and the boom down buttons until the display indicates that the lower calibration point has been obtained. This may require holding the buttons for several seconds after the boom has touched the rest pad.

8 Press OK on the display to continue with the procedure to capture the maximum angle point.
9 Operate the boom up function until the boom reaches its maximum angle. Continue holding the function enable and boom up buttons for several seconds until the display indicates that the upper calibration point has been obtained. This may require holding the buttons for several seconds after the boom reaches its maximum angle.
10 Follow the on-screen prompts to lower the boom until the display indicates the calibration is complete. If this step isn’t done, the boom will be in the safety envelope when the calibration procedure ends
