Buhler 2360, 2335, 2425, 2290, 2375 manual Calibrating the Electronic Instrument Control System

SECTION 2 - OPERATION

CALIBRATING THE ELECTRONIC INSTRUMENT CONTROL SYSTEM

As detailed in “Normal Operation of the Electronic Control Instrument System” (earlier in this section), certain values must be preprogrammed into the control module for proper operation and maximum benefit.

A detailed description of proper programming and calibration of the module follows. It is not necessary to follow the steps in the order shown to properly program the module. Select the area to be calibrated and follow the instructions given. The only required step is “Entering the Calibration Mode.” If the tractor is being calibrated for the first time, use the following steps in the order shown.

All programming and calibration is done with the key switch in the “RUN” position and the engine off.

There are nine possible items to calibrate when in one of the three rotary select switch positions:

Tractor Ground Speed Position

1.Setting the Tire Rolling Radius

2.Programming Units of Ground Speed Measurement (MPH or km/h)

Service Interval One Position

3.Service Interval One Reset

4.Service Interval One Alarm Reset

Service Interval Two Position

5.Service Interval Two Reset

6.Service Interval Two Alarm Reset

Tractor Accumulated Hours Position

7.Setting the Final Drive Ratio (FDR)

8.Setting the Transmission Output Shaft Gear Profile (GEAR) N14 engine only

9.Setting the Engine Flywheel Ring Gear Profile (Eng)

Entering the Calibration Mode

It will be necessary to put the system into the calibration mode. To do this, the ignition must be in the “OFF” position. Place the rotary select switch in the desired position to be calibrated. Press and hold the acknowledge/reset button. Continue to hold the acknowledge/reset button and turn the ignition to the “RUN” position. The display monitor will go through its normal initial test sequence. Once this is done, release the acknowledge/reset button.

The monitor is now in the calibration mode and ready to be programmed. No matter which of the nine items is to be calibrated, the upper portion of the monitor will always display the words “SET UP” along with a flashing display based upon the position of the rotary select switch. This tells the user that he is in the calibration mode for that particular function.

NOTE: At any time, the calibration mode can be exited by the user by simply turning the ignition to the “OFF” position and then turning the ignition back to the “RUN” position. This will place the system back into the normal operate mode. The words “SET UP” will disappear from the upper portion of the monitor display.
