What to do if the Norac UC4+ Controller LCD screen does not light up?
- C
  Charles WebbAug 20, 2025
  If the LCD screen on your Norac Controller doesn't light up, there are several potential causes: * **Inadequate power supply:** Ensure the UC4+ power cable is properly connected to both the UC4+ control panel and the sprayer's power supply. Verify the sprayer's power supply voltage is above +12V, measuring it while the valve is in use to account for potential voltage drops. * **Defective power cable:** Follow the steps above to check the power supply. Wiggle the cables/wires. If the screen still doesn't light up, the cable may need repair. * **Damaged LCD screen:** If checking the power and cable doesn't resolve the issue, the LCD screen itself may need replacement.

Why does my Norac Controller UC4+ randomly switch between AUTO and MANUAL modes?
- A
  Adrian RobinsonAug 22, 2025
  The random switching between AUTO and MANUAL modes on your Norac UC4+ controller could be due to: * **Poor cable connection:** Ensure all cables are correctly and tightly connected according to the UC4+ Installation Manual, and that they are free of corrosion. Wiggling the cables in AUTO mode can help detect interruptions, as this will switch the system to MANUAL mode. * **Defective cables:** If the connections are secure but the issue persists, the cable(s) may need repairing. * **Electrical noise:** Electrical noise on the sprayer's D.C. system might be the cause. Try adding a power line filter or freewheeling diodes on one or more of the sprayer's solenoid valves to mitigate this.

Why does height increase/decrease unintentionally on Norac Controller?
- D
  Daniel OrtizAug 26, 2025
  Unintentional height adjustments on your Norac Controller may be caused by intermittent electrical noise on the main lift interface cable(s). Try installing a power line filter to mitigate this. Additionally, diodes may need to be installed in the main lift lines, sized appropriately for the sprayer (e.g., IN5408 for a 3 Amp or smaller coil). Contact NORAC for further details.

What to do if Norac UC4+ sensor appears not to work and displays "NC"?
- J
  Jordan PatelAug 29, 2025
  If your Norac Controller displays "NC", indicating the sensor isn't working, it could be due to: * **Serial number mismatch:** Verify the serial number (SN) entered in the control panel matches the connected sensor's SN for the respective boom location. Re-enter the correct SN if necessary. * **Cable issues:** Ensure all cables are correctly connected according to the UC4+ Installation Manual and perform Sensor Swapping. If the issue continues, the cable(s) may need repair. * **Damaged sensor:** If the problem persists after swapping the sensor to a different boom location, the sensor may need repairing.

Why is part of the LCD screen black on my Norac UC4+?
- N
  Nicholas OneillSep 1, 2025
  If part of the LCD screen on your Norac Controller is black, it's likely due to the control panel being mounted in direct sunlight. High temperatures cause the LCD screen to turn black (high contrast). This should disappear when the LCD cools down.

What causes boom to raise when it should lower, or vice versa, on Norac UC4+ Controller?
- J
  Jerry SmithSep 5, 2025
  If your boom raises when it should lower, or vice versa, on your Norac Controller, the problem likely lies in: * **Valve cable connection:** Double-check the cable connection to the NORAC valve block. * **Plumbing:** Ensure the plumbing is correct: the boom raise line(s) should connect to the “B” port(s) on the NORAC valve block, the boom lower line(s) to the “A” port(s), and the Tank and Pressure lines to the Tank (“T”) and Pressure (“P”) ports, respectively.

Why is Norac Controller displaying "SNR xxxx" during Automatic System Setup?
- C
  Connie BakerSep 7, 2025
  The "SNR xxxx" message during Automatic System Setup on your Norac Controller indicates: * **Improper sensor alignment:** Check the alignment of the sensor involved with the error. For instance, if the System Setup is performing a "LftDet" and this message appears, check the Left wing sensor(s). * **Poor targets:** The sensor may be having trouble reading from wet gravel or stubble. Try a different target.

What causes boom to creep upwards when in the transport position on Norac UC4+ Controller?
- J
  Jennifer SteeleSep 8, 2025
  If the boom creeps upwards when in the transport position on your Norac Controller, consider these causes: * **Valve leakage:** The valve block may need repairing or replacing. * **Faulty check valves:** The check valve(s) may need replacing.

What does it mean when Norac UC4+ Controller sensor is displaying "###" or "-##"?
- B
  Brandon DunnSep 12, 2025
  If the Norac Controller sensor is displaying "###" or "-##", indicating a value that's too high or low, it could mean: * **Boom section height:** The boom section might be too high ("###"). Lower the boom section. The sensor is reporting a reading that has too many digits to display on the LCD screen. When the boom returns to normal heights, the reading should reappear on the screen. * **Sensor Zero Height:** The sensor Zero Height setting may be incorrect. Check the sensor “Zero Height” and calibrate if necessary. This can occur when sensors have been “swapped” from different mounting locations. * **Sonic targets:** The sensor may be facing very strong sonic targets (e.g., concrete). Try a different/adequate target.

What causes hydraulic oil overheat in Norac UC4+ Controller?
- M
  Michael WatersSep 13, 2025
  Hydraulic oil overheating in your Norac system can be attributed to: * **Setpoint maintenance:** Maintaining the setpoint increases oil temperature. Lowering the Sensitivity ("Sensi") setting may reduce system activity and lower the temperature. * **Plumbing configuration:** Plumbing single acting systems as double acting with both A ports orificed may reduce heating. Contact NORAC for more information.
