12. VERIFY OPERATION OF HYDRAULICS AND SET THE STEERING
CONTROL RATE
Clean and pick up the area around the vehicle and make certain that it is safe to operate. Start the engine
and check hydraulic connections for leaks. Rotate the steering wheel from one extreme to the other and
back to center, check for leaks. While steering through the extremes of movement, check the cables and
hoses for wear points and strain, adjust as necessary.
If using a Matrix™ series console and PWM control, then the oil ow adjustment
is accomplished through the console. Refer to the Matrix user guide for further
instructions.
Adjust the hydraulic oil ow control knob on the FieldPilot valve to a starting
position of 2½ turns from completely closed. Adjust the oil ow by turning the knob clockwise
to reduce ow (increase seconds) and counter-clockwise to increase ow (decrease seconds).
Use the electronic steering control console to perform the left to right steering test, counting the seconds
to move the wheels from full left to full right and also in the opposite direction. It is a good idea to have the
vehicle moving forward very slowly during these tests so there is not excessive side pressure on the tires.
If you nd that the machine steers in the opposite direction from that being commanded in this steering test
sequence, switch the valve connectors at the FieldPilot valve coils.
Do this a number of times, adjusting the oil ow between tests, until a lock to lock steering response of
approximately 16 seconds is observed using a CenterLine® 220. Adjust to 12 seconds when using a
CenterLine® 230BP. Use the locking nut to secure this ow setting. The coils on the FieldPilot valve also
have manual push button overrides.
Note: To activate the manual overrides, a tool such as a small screwdriver or allen wrench must be inserted
into the end of the coil to depress the override button.
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 steering linkages.
13. COMPLETE ELECTRONIC INSTALLATION
Refer to the owner’s manual supplied with the automated steering system to complete the electronic
