To enter Security Code, while keeping the switch 8, press and hold 3 and 4 together for more than 2 seconds, digital display at top will read. Press 1 (to increase) or 2 (to decrease) to change the first digital position from " " to " " when " " appears press 3 and the second digital position will start to flash. Follow the same procedure as with the first digital position until all six position have been changed to read " ", then wait for ten seconds and you are in, or press switches 3, 4 and 8 and hold for more than 2 seconds, digital display will read.

EXAMPLES
This code shows shows the status of the travel speed solenoid, the right" " is for the tortoise position and a " " is for the rabbit position Move the flashing number to the right, increase the number number to " ", this shows status of the cold temp mode. " " appears to indicate oil temp below operating temperature " " indicate oil temp at operating temperature
NOTE : To change the value of flashing numbers, the switch 8 arrow light must be "OFF"

GOVERNOR FAULT CODE LIST If calibration procedure cannot be completed, the six digit display will show an error code. I f an "H" appears in the fourth character from the right and nothing appears in the third position from the right while the calibration procedure is being performed, and error code is present. If an "H" appears, push button "8". The error code will appear on the right most three character positions. The chart that follows shows the possible error codes.
ERROR CODE DISPLAY
ERROR DETAILS
1
70 HF 01
Engine stops
2
70 HF 02
Speed sensor is abnormal
3
70 HF 03
Load is applied
4
70 HF 04
High idle engine speed is too fast
5
70 HF 05
Low idle engine is too low
6
70 HF 06
Governor actuator feedback sensor circuit open
7
70 HF 07
Governor actuator feedback sensor circuit shorted to body ground
8
70 HF 08
Abnormal feedback signal to governor actuator
70 Hd 00
Retry error or too much hysteresis
If the error code "70 Hd 00" appears, push button "3" until the character display stops flashing. Push button "1" to select the previous calibration data or push button "2" to select the default calibration data. Push button "8" to t o store the above calibration 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.
