GOVERNOR FAULT CODE LIST

If calibration procedure cannot be completed, the six digit display will show anerror code. I f an "H" appears in the fourth character from the right and nothingappears in the third position from the right while the calibration procedure is beingperformed, and error code is present. If an "H" appears, push button "8". The errorcode will appear on the right most three character positions. The chart that followsshows the possible error codes.

Abnormal feedback signal to governoractuator

Retry error or too much hysteresis

If the error code "70 Hd 00" appears, push button "3" until the character displaystops flashing. Push button "1" to select the previous calibration data or pushbutton "2" to select the default calibration data. Push button "8" to store the abovecalibration data. Make the necessary repairs and repeat the calibration procedure.

NOTE : When the calibration is completed, the display may flash between "70 End" and "70 06", the governor actuator cable is too loose by six full turns. I f a set of numbers such as "70 - 60" with the minus sign appears, the governor actuator cable end is too tight by six full turns.

I f a set of numbers such as "70 20 13" is displayed, the four numbers on the right side indicate the actual engine speed which is below the correct specification for high idle.

PRACTICAL EXERCISES

1. PERFORM ALL STEPS PROCEDURES OF CUSTOMER MODE SETTING.

2. PERFORM ALL STEPS PROCEDURES TO CHECK SERVICE CODES GROUP 10, 20, 60, 70 AND 80.

3. WITH A PRESSURE GAUGE INSTALLED ON THE PS PORT, PERFORM THE FOLLOWING TEST :

a - PS PRESSURE SWEEP b - PS PRESSURE CALIBRATION c - ENGINE PERFORMANCE TEST (Using modulating PS pressure to overload the engine)

4. WITH A PRESSURE GAUGE INSTALLED ON THE HIGH PRESSURE PORT, PERFORM THE FOLLOWING TEST :

a - MAXIMUM SYSTEM PRESSURE b - CHECK THE SHIFTING POINT OF 2 SPEED AUTOMATIC CHANGE SPEED VALVE

5. REDUCE TO 25% THE AVAILABLE POWER FOR ATTACHMENT PUMP
