After OK key (I) is pressed, the screen in Illustration 9 will be displayed. The password for the service menu is "FFF2". The keys for direction are used to input the password. Press left key (D) or right key (F) in order to change the position of the flashing character. Press OK key (I) in order to enter the highlighted character.
After entering the last letter of the password, the monitor will continue with the "SERVICE" screen.
Repeatedly press down key (E) in order to highlight the "DEVICE TEST" line on the display.
After the "DEVICE TEST" line is highlighted, press OK key (I).
Once the "DEVICE TEST" screen is displayed, press down key (E) until "POWER SHIFT PRES" appears on the display.
When "POWER SHIFT PRES" is highlighted, press OK key (I).
Place the machine controls at the following settings: engine speed dial 10 and AEC switch OFF. Refer to Testing and Adjusting, "Engine Performance - Test (Engine Speed)" for engine rpm settings. Note: Press OK key (I) within 5 seconds after completion of Step 3.j in order to ensure high idle.
The "POWER SHIFT PRES" will now be displayed. Line 4 of the display will now change to a numeric value. These characters represent the power shift pressure (kPa).
Press left key (D) or right key (F) to increase or decrease the value that is displayed on line 4 of the display. Pressing left key (D) decreases the power shift pressure. Pressing right key (F) increases the power shift pressure. Note: The value for power shift pressure on the monitor may not always match the pressure reading on the pressure gauge. Adjust the value on the monitor until the desired power shift pressure is attained on the pressure gauge for power shift pressure. The actual power shift pressure must be 2400 kPa (350 psi) on the pressure gauge.Note: To prevent a change in power shift pressure during the main pump flow test, do not exit the "DEVICE TEST" screen and do not turn the key to the OFF position.Note: Refer to Systems Operation, "Monitoring System" for additional information on Service Mode.
In order to perform flow measurements for either one of the pumps, the other pump must not be under load.
