Why is Norac UC4+ display stuck at “Mo|ot’n Dly" or "KP Stp 9"?
- T
  Tracy BurnsSep 16, 2025
  If your Norac Controller display is stuck at “Mo|ot’n Dly" or "KP Stp 9", it could be due to: * **Sensor proximity:** The sensor may be too close to the boom. Move the sensor to a better location, ideally 25cm (9 inches) in front of and 25cm (9 inches) above the spray nozzle, ensuring a 30cm (12 inch) diameter clear view of the ground. * **Weak target:** The target may be too weak. Move to a new location with dirt or gravel on the ground. Ensure there is no grass or other plants under the sprayer boom, and verify the sensor is approximately parallel to the ground.

What to do if boom does not raise or lower on Norac UC4+ Controller?
- K
  Kimberly MasonNov 22, 2025
  If the boom on your Norac Controller isn't raising or lowering, consider these potential causes: * **Hydraulic oil supply:** Make sure oil is being supplied to the NORAC valve block in the correct direction (Tank and Pressure lines). A check valve might prevent oil flow if the direction is incorrect. * **Quick coupler connections:** Ensure all hydraulic quick couplers are properly connected. * **Back-pressure:** There may not be enough back-pressure to activate the check valves in the NORAC valve block. Place orifices in the “A” lines going to Tank (“T”) to create sufficient back-pressure. * **Cable/valve issues:** Check cable connections between the control panel and valve block for tightness and corrosion. Verify voltage at the valve connection; if there's no voltage, the cable(...

How to fix Timeout! error during System Setup on Norac UC4+ Controller?
- J
  Jessica BrownNov 27, 2025
  A "Timeout!" error during System Setup on your Norac controller can arise from several factors: * **Hydraulic cylinder stroke:** Ensure the hydraulic cylinders are not obstructed by a cylinder cap. If a cylinder is fully extended or retracted, manually reposition the boom to the middle of the cylinder stroke and resume setup with the "AUTO (YES)" switch. For booms that don't adjust below the main boom level, ensure the main boom is within 125cm (50 inches) above ground before attempting an Install or ReTune. * **Boom speed:** Ensure the hydraulic oil is at working temperature, as a slow-moving boom can trigger this error. * **Hydraulic pressure:** Confirm the solution pump is running and manually put the hydraulic system into high pressure during main lift ("MlfDet") Boom Geometry T...
