1. Install Roof Module 1.1 Safety Notes The AutoFarm system must be powered OFF when installing or removing the roof module. The supplied locking pin or a padlock must be in place whenever the vehicle is in operation. The roof module must be removed when transporting the vehicle at speeds above 30 mph. Make sure that you are in a stable position on the tractor platform when removing the roof module, so that you do not fall or drop the roof module. 1.2 Install the Mounting Rail Remove the cab roof bolts. 1
Attach the mounting rail brackets to the roof. Align the mounting rail to mounting holes and fasten the mounting rail to the mounting rail brackets. The lettered holes should be on the left side of the tractor. 2
1.3 Mount the Roof Module Slide the roof module into locked position. The cable connection must be on the left side of the tractor, facing the rear. cable connector Make sure that the spring lock is in place. locked position 3
Insert and close the locking pin through the holes in the roof module and the mounting rail. Note that a padlock can replace the locking pin. locking pin Attach the radio modem antenna. Note: The antenna should be attached hand tight - do not use any tools to tighten the antenna. 4
2. Install the User Terminal 2.1 Assemble and Mount the User Terminal Bracket Mount the bracket assembly to the cab post. 2.2 Mount and Adjust the User Terminal Attach the adjustable arm to the user terminal. mounting plate 5
Remove the travel stop on the bracket assembly. Install user terminal arm onto the cab bracket. 6
Tighten the arm onto the cab bracket. Replace the travel stop. 7
Adjust user terminal arm tightness. Adjust user terminal viewing angle. 8
3. Install the Wheel Angle Sensor (WAS) 3.1 Mount Tie Rod and Sensor Brackets Mount the sensor bracket and attach the Wheel Angle Sensor. wheel angle sensor sensor bracket Mount the linkage bracket and attach the linkage arm. 9
Attach and connect the two linkage arms. 3.2 Adjust the Sensor and Linkage Arms Adjust linkage arm length and/or linkage bracket position to obtain between 3200 and 3800 counts. Turn the wheels all the way in both directions to make sure the linkage arms can move without interference. Note: This step is done during the calibration and tuning steps. 10
4. Assemble and Mount the Hydraulic Valve 4.1 Install the Hydraulic Valve Fasten bracket into place. valve bracket Mount the hydraulic valve. 11
5. Install the Hydraulic Hoses 5.1 Route the Hydraulic Hoses Route the left/right Steer In Steer Out hoses from the AutoSteer valve, under the cab, to the front right of the tractor. Note: Secure the hoses with cable ties and be sure they are clear of moving parts and heat sources. 5.2 AutoSteer Valve Port Connections Hydraulic Hose Steer In (Right) Steer In (Left) Steer Out (Right) Steer Out (Left) Pressure Return Load Sense Pressure Transducer Valve Port Label SR SL Right Left P T LS Trans 12
5.3 Connect the Hydraulic Hoses Detach existing steer hoses. Original right and left Steering hoses that will be opened to connect the AutoSteer hoses Open the tractor s steering lines and connect AutoSteer IN/OUT hoses. Connect the right Steer In hose to the bottom hose on the tractor steering unit. Connect the left Steer In hose to the top hose on the tractor steering unit. Connect the right Steer Out AutoSteer hose to the bottom steel steering line. Connect the left Steer Out AutoSteer hose to the top steel steering line. Note: Right steering hoses must be connected to right steering lines and Left steering hoses must be connected to left steering lines. Check for oil leaks after final assembly and the tractor engine has been turned on and steered. 13
Connect power beyond hoses to valve. return load sense pressure Connect hoses to power beyond unit. return load sense pressure 14
5.4 Attach the Pressure Transducer Attach the 90 degree fitting to the port marked trans on the AutoSteer valve. Note: Use teflon tape to ensure a good seal. Attach the pressure transducer to the 90 degree fitting. Note: Use teflon tape to ensure a good seal. 15
Attach the cable connector from the valve harness to the pressure transducer. pressure transducer cable connector make sure to line up the connectors correctly. do not force the connection. 16
6. Install the SA Module 6.1 Mount the SA Module Bracket Locate the area to mount the bracket. area for mounting bracket Mount the bracket. 17
6.2 Mount the SA Module to the Bracket Note: It is essential that the SA Module is NOT mounted so that the cable connection is on the top or on the side with the cable going up. 18
7. Install the Main Cable Harness 7.1 Attach the Main Cable Harness to the User Terminal. 7.2 Attach the Cable to the Power Supply 7.3 Attach the Main Cable Harness to the Roof Module Route the cable out the rear of the cab floor, behind the seat, under the floor mat. The existing hole may need to be widened or a new hole drilled. 19
Attach the cable to the roof module. Route the cable down the left side of the cab and secure with cable ties. 20
