Case 850K Calibration Procedure
Push and hold the bump up and bump down buttons on the directional control handle.
Start the engine and continue to hold the bump up and bump down buttons until 'HP XX-XX' is displayed. Release the buttons.
If needed, use the bump up/down buttons to select the machine horsepower rating that is being calibrated, 70-80 (650K / D75), 80-90 (750K / D85), or 90-100 (850K / D95).
The improper horsepower range selection will cause the calibration to be incorrect and machine functions will be impaired.
When the machine being calibrated is properly displayed, press both the bump up and bump down buttons for one second and release, the instrument cluster should read 'CAL BRAKE' or 'CAL BRK'. Smoothly move the brake pedal from release to applied position two-to-four times.
Press both the bump up and bump down buttons for one second and release, the instrument cluster should read 'CAL THROTTLE' or 'CAL FTR'. Move the hand throttle to high idle. Move the decelerator pedal from high to low idle, two to three times to set the end points.
During operation if the instrument cluster reads out 'ERR RANGE', one or both minimum/maximum values are out of range or one or both potentiometers were not moved in the last five seconds since the start of calibration mode.
With the decelerator pedal fully depressed to the low idle position, press both the bump up and bump down buttons for one second and release, the instrument cluster will read 'CAL INC'. Move the decelerator pedal from low idle to high idle smoothly and steadily over a period of 15 to 20 seconds one time to set the engine calibration curve. The instrument cluster will then read 'CAL DONE'. Stop and restart the engine, values are stored in internal memory.
During this operation if the instrument cluster reads out 'ERR SPEED', the throttle was not in the low idle position at the start of 'CAL INC', the engine is not running, or no engine speed signal is being received.
If at any time during calibration the instrument cluster reads 'CAL FAIL', stop the engine and restart the procedure.
