ELECTRICS 2.31 9. Press the push button (19) marked “CAL” and release. The action will return the display module to the normal operating mode. Green indicator (7) and red indicator (16) will stop flashing. If 100% load is still applied, all indicators will illuminate and the audible alarm will sound. Calibration of the system is now complete. 10. Retract the boom. The rear wheels will come back into contact with the ground. Leave the load in place on the work tool. 11. Carefully extend and retract the boom whilst observing the display module. Ensure that the display module gives the readings that are expected. Refer to “Description - Display module”. 12.
Set down the load and disengage from the work tool. 13. Retract the boom. Lower the work tool to the ground and stop the engine. Turn engine start switch to OFF position. Resetting the zero point If it is necessary to readjust the zero point without resetting the 100% calibration point, perform the following procedure. Before proceeding with the calibration set up ensure the following conditions are met: 1. The machine is parked on level ground. 2. Wheels are steered to the straight ahead position. 3. The boom is fully retracted. 4. The bottom of the coupler is 150 mm (6 in.) above the ground. 5. A work tool is not installed on the coupler. 6.
The engine is running and the parking brake is applied. The calibration procedure is as follows: 1. Remove the display module (1) from the cab side console in order to gain access to the push buttons (19), (20) and (21) that are required to calibrate the LSI. Refer to “Procedure to replace the display module” for further information.
