  • Page 10: Installation Procedure

    Inspect boom suspension wear-pads for excessive wear o This UC4+BC+RA1 kit is designed to control the RAU variable-geometry boom. This requires that the boom is fitted with variable-geometry tilt cylinders. If this install requires adding tilt cylinders:...
  • Page 11 o Set the boom suspension to be critically damped (Figure 4). Adjust the boom springs and dampers accordingly. A) Unlock the boom, and push boom tip down approximately 75 cm (30 inches). B) Hold the boom steady for a moment, and release. C) Ensure the boom returns to its relaxed state as quickly as possible, with little to no overshoot.

    3. Mount the NORAC UC4+ ultrasonic sensor (E02) into the sensor brackets. The sensors should be oriented forward (ahead) of the boom (see Figure 8 and Figure 10).
  • Page 13 General mounting rules for UC4+ ultrasonic wing sensors: a) In its lowest position, the sensor mouth must be 9 inches or more from the ground. b) The bottom of the sensor must be at least 9 inches in front of the spray nozzles. c) The bottom of the sensor must be at least 9 inches above the spray nozzles.

  • Page 14: Suggested Mounting Location For Wing Bracket On Hsa (Aluminum) Boom

    4.3.1 Suggested Mounting Location for Wing Bracket on HSA (Aluminum) Boom Mounting the NORAC UC4 breakaway bracket to the HSA aluminum boom will require the use of a RAU aluminum boom clamp, as illustrated below. RAU CLAMP Figure 11: UC4 Sensor Bracket mounted to boom using RAU HSA boom clamp Using this clamp will also require adjusting the hole width of the NORAC bracket to accommodate the larger bolts and differences in dimensions between the 2 parts.
  • Page 15 NOTE: It may be necessary to create an adapter to mount the NORAC UC4+ bracket to the RAU HSA boom. This bracket, when used in conjunction with the RAU HSA boom clamp, will prevent the boom from rotating down towards the ground due to the clamp slipping on the aluminum.
