Service and Repair Manual July 2019Turntable Rotation Components78 S-40 XC • S-45 XC • S-40 TraX • S-45 TraX Part No. 1286829GTHow to Calibrate the TurntableTilt SensorNote: Perform this procedure with the boom fullyretracted and in the stowed position and with themachine on a firm, level surface.Note: A digital level will be required to perform thisprocedure.1 Enter Service Mode. Refer to RepairProcedure, How to Enter the Service Mode.2 Press the settings button above the displayand navigate t the Sensor Calibrations menu.3 Navigate to the Chassis Tilt Sensor calibrationscreen.4 Select and start the calibration procedure.5 If the machine is not sufficiently level, theprocedure will fail with the message that thechassis no not sufficiently level. Move themachine to a more level location if this occurs.6 The first calibration is machine pitch. This isthe pitch of the machine from the platform endto the counterweight end of the machine.7 Place the digital level onto the swing chassisbearing plate, which is located to the left of thefuel tank. Orient the level along the pitch axisof the machine.8 Enter the value as seen on the digital level intothe ground control display. If the digital level isshowing a negative value, enter it as a positivenumber. Press OK when the value on theground control display matches the value ofthe digital level (excluding the plus/minussign).9 A graphic of the machine pitch will now beshown on the display. By pressing the UP orDOWN buttons, the graphic will change toshow the counterweight being uphill ordownhill. Select the image that corresponds tothe current pitch of the machine and press OK.Turntable Pitch1 uphill2 downhill10 The next calibration of the machine is themachine roll. This is the angle of the machinefrom side to side.11 Place the digital level onto the swing chassisbearing plate, which is located to the left of thefuel tank. Orient the level along the roll axis ofthe machine.12 Enter the value as seen on the digital levelonto the ground control display. If the level isshowing a negative value, enter it as a positivenumber. Press OK when the value on theground control display matches the value ofthe digital level sensor (excluding theplus/minus sign).
