VALVE HYD SOL CC PROPORTIONAL 12V DEUTSCH CONNECTORS Do not use high speed power tools/drills when installing hardware. The use of dielectric grease is not recommended on any NORAC electrical connections. To ensure all stainless steel hardware does not gall or seize apply a light coating of the supplied Permatex Anti-seize grease to all threaded parts upon installation.
4 Ultrasonic Sensor Installation 4.1 Bracket Assembly 1. Assemble the breakaway sensor bracket as illustrated in Figure 3, following the instructions below. Figure 3: Breakaway Bracket Assembly 2. Compress the spring and insert it together with the collar into the base. 3.

4.2 Ultrasonic Sensor Serial Number Arrangement When installing the UC5 sensors, start with the smallest serial number on the left-hand side, and proceed to the largest serial number on the right hand side. Each UC5 sensor has a serial number stamped on the sensor housing. Apply a light coating of the supplied Permatex Anti-seize grease to all threaded parts upon installation.

4.3 Ultrasonic Sensor Mounting Guidelines The following guidelines will ensure optimal sensor performance and prevent sensor measurement error. These rules should be followed for both the wing sensors and the main lift (middle) sensor. 1. In its lowest position, the sensor must be 9 inches (23 cm) or more from the ground (A). 2.

If the sensor is mounted to this portion of the boom, the system will force the boom downwards towards the ground as the boom folds backwards. 4. Mount the NORAC ultrasonic sensor into the sensor bracket and run the sensor cable through the sensor tube.

4.5 Main Lift Sensor Installation 1. There are a variety of ways to mount the main lift bracket on most sprayers. The bracket should position the sensor approximately in the center of the sprayer, forward of the boom. 2. Mount the ultrasonic sensor to the main lift bracket. Run the sensor cable down the center of the main lift bracket tube.
5 Roll Sensor Installation 5.1 Bracket Assembly 1. Securely mount the roll sensors to the included roll sensor brackets using the #6 machine screws. Tighten screws to 10 in-lbs (1.1 Nm). 2. The orientation of the mounted roll sensor to the roll sensor bracket will depend on the bracket mounting.

5.2 Roll Sensor Mounting Guidelines: Center Pivot Booms 1. When mounting the roll sensors, mount the roll sensor without the temperature probe on the boom frame and the roll sensor with the temperature probe on the chassis (non- pivoting portion of the sprayer). For optimal performance, minimize the distance between the roll sensors (A) and minimize the height from each roll sensor to the pivot point (B).
A good spot to mount the UC4.5 control panel is on the right hand side of the cab to the Roll Over Protection Bar (ROP). Four pilot holes for the screws provided need to be drilled to facilitate the control panel mounting.

Figure 13: Cable Configurations: C03, C08, C11 and C12 7. Connect the 6-pin shroud (S6) on C12 to the 6-pin tower (T6) on C11. Route the free end of C12 to the existing valve block. 8. Insert the connector tees (R2A-P2A and R2C-P2C) on C12 between the matching connections on the existing sprayer valve harness: MAIN UP and MAIN DOWN.

12. Fasten the 8-way coupler (E11) to the boom with cable ties. 13. Connect P6 on C11 to a 2-way coupler (E12). Connect cable C08 between the 2-way coupler and the 8-way coupler. 14. Connect both roll sensors to the 8-way coupler. 15.
Component failure due to oil contamination is not covered under the NORAC UC4.5 system warranty. It is recommended that a qualified technician perform the hydraulic installation. 7.1 Valve Installation 1.

1. Install two (2) springs (not included in kit) to put tension on the center section of the boom. The springs should have a 4-5cm diameter with a wire diameter of 3-4mm. Figure 16: Springs Installed NORAC also recommends installing a damper cylinder. Figure 17: Damper Cylinder Installed...
2. If any functions do not work, review the hydraulic and electrical portions of this manual to check for proper installation. 3. Turn on the power for the UC4.5 Control Panel using the switch on the side of its chassis. 4. Begin the AUTOMATIC SYSTEM SETUP procedure as described in the UC4.5 Spray...
