The controller uses a calibration sequence to optimize the control system. The optimizing ensures full spool stroke (full flow) while preventing over stroke (loading) of the actuator and resets the calibration points in the controller.
NOTE: The Actuator Test is the preferred method to calibrate the lift and tilt actuator. (See Actuator Testing on Page 60-160-1.)
NOTE: This calibration procedure must be followed when replacing the hydraulic control valve, lift or tilt actuator, or drive controller. Failure to calibrate after component replacement may result in poor performance or reduced life of actuator(s).
With an operator in the seat and the seat bar down.
Close the cab door. (If loader is equipped.)
Place the loader Control Pattern Switch (Item 1) [Figure 60-160-8] in the ISO position.
Move the right joystick to the forward-right corner position [Figure 60-160-9] and hold in position.
Turn the key (Item 1) [Figure 60-160-10] to the RUN position or press the RUN/ENTER button (Item 1) [Figure 60-160-11] for power, without starting the loader.
The loader Control Pattern Switch (Item 1) [Figure 60-160-8] will start flashing and will continue to flash until the calibration procedure is completed.
At the left panel, press the PRESS TO OPERATE Button (Item 1) [Figure 60-160-12] while holding the right joystick in position.
Release the joystick.
NOTE: During the calibration cycle, the system will beep three times. Once the calibration is complete code 32-24 (Calibration Performed) will be generated.
The ACS controller will cycle the actuators.
The lift and tilt calibration is complete.
