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.

please refer to manufacturer’s specications for appropriate 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.
