Valve Setup
Valve Setup is used to confi gure Valve Frequency, Minimum Duty
Cycle Left, Minimum Duty Cycle Right and Maximum Duty Cycle.
1. Press VALVE SETUP ICON .
2. Select from:
►Valve Frequency – used to drive the steering valve
►Minimum Duty Cycle Left – sets the minimum amount of
drive required to begin steering the vehicle left
►Minimum Duty Cycle Right – sets the minimum amount of
drive required to begin steering the vehicle right
►Maximum Duty Cycle – sets the maximum speed that the
wheels will steer from left to right/ right to left (lock to lock)
OR
Press PAGE RIGHT ARROW to cycle through all settings.
NOTE: Options labels are current settings. While in a setting screen,
press icon to view available factory settings and setting
ranges.

Valve Frequency
Valve frequency is used to drive the steering valve. The type of valve
being used determines the frequency. Range is 1 - 5000.
1. Press FREQUENCY ICON .
2. Use the entry screen to establish the valve frequency.
3. Press
►PAGE RIGHT ARROW to proceed to Minimum Duty Cycle
Left.
►FIELDPILOT SETUP TAB to return to main FieldPilot
Setup.

35-02184 FP. CC, PWM 7.9 OC 175 hz
35-02185 FP. CC, PWM 2.1 OC 110 hz
35-02186 FP. CC, PWM 4.0 CC 110 hz
35-02187 FP. CC, PWM 7.9 CC 175 hz
For valves manufactured by sources other than TeeJet Technologies,
refer to manufacturer’s specifi cations for appropriate valve frequency.
Minimum Duty Cycle
Minimum Duty Cycle sets the minimum amount of drive required to
begin steering the vehicle left or right. Range is 0.0 - 50.0.
RECOMMENDATION – Have a large area of clear space available to
perform test cycles.
NOTE: If the valve frequency is set below 15 Hz (non proportional),
set the amount of drive to “25.0”. Cycle test is not necessary.
WARNING: PINCH POINT HAZARD!
To prevent serious injury or death, avoid unsafe practice
while manually operating hydraulic steering circuits. Keep
others away and stay clear of mechanical linkages.
