Valve Frequency
Valve frequency is used to drive the steering valve. The type of valve
being used determines the frequency. Range is 0.9 - 15000.1.
NOTE: See section “Verify Operation of Hydraulics and Set the
Steering Control Rate” of your specific FieldPilot Installation
Manual for your specific valve frequency.
1. Press the KEYPAD icon .
2. Use the entry screen to establish the valve frequency.

Minimum/Maximum Duty Cycle Tests
Minimum Duty Cycle (Minimum DC Left + Right) sets the minimum
amount of drive required to begin steering the vehicle left or right.
Range is 0.0 - 50.0.
Maximum Duty Cycle sets the maximum speed that the wheels will
steer from left to right / right to left (lock to lock). Range is 25 - 100.
NOTE: A GPS signal is required for these tests.
Machine must be at normal operation RPM.
RECOMMENDATION: Have a large area of clear space available to
perform test cycles. Vehicle speed must be between
1.0 mph and 8.0 mph / 1.5 - 13.0 km/h (0.4 - 3.6 m/s).
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 linkage.
Minimum Duty Cycle Left Test
Minimum Duty Cycle Left sets the minimum amount of drive required
to begin steering the vehicle to the left.
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.
1. Press the KEYPAD icon .
2. While the vehicle is moving in a slow forward straight line motion
between 1.0 mph and 8.0 mph / 1.5 - 13.0 km/h (0.4 - 3.6 m/s),
press
Test Left
.
3. Press the engage/disengage switch or foot switch to activate the
test.
4. Slowly increase the duty cycle number using the UP arrow
until the vehicle begins to turn left.
5. Turn the steering wheel or press the engage/disengage switch or
foot switch to complete the test.
