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. For
recommendations and factory settings for the FieldPilot or UniPilot
setup values, see chart on page 19.

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. Default is 20%.
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.
Default is 50%.
NOTE: A GPS signal is required for these tests.
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/hr (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.
