Troubleshooting a Non-Responsive Moisture Cable

Moisture monitoring is critical in grain management systems, ensuring optimal conditions for storage and quality maintenance. However, encountering a non-responsive moisture or temperature cable can disrupt operations. Here’s a quick guide to troubleshooting and resolving issues with your moisture/temperature sensing equipment:

  1. Inspect for Physical Damage: Start by visually examining the Sensing Cable, Cable Node, and lead wire for visible damage. Look for cuts, abrasions, or signs of wear that could affect functionality. If damage is detected, replace the affected components. We carry parts and provide the replacement service.
  2. Check Wiring Inside the Cable Node: We do not suggest you climb your grain bin. Please call IFND for service. This team is trained and properly equipped with teh necessary safety equipment. While on top of your grain bin, our service crew will use a Philips head screwdriver to open the Cable Node. Inspect the wiring for solid connections without loose wires or obvious shorts. Using a multitester (voltmeter) can help identify open or short-circuited wires. For CN01 models, ensure the wiring is secure in the orange terminal block where INT2 is connected. For CN08 models, verify correct wiring in the CNE board (“puck”) at the base of the node.
  3. Verify with a handheld monitor: If available, connect a StorMax or OPI Blue Lite hand-held monitor to the pigtail at the cable head. Check for meaningful readings indicative of moisture levels. A lack of response suggests a faulty cable that needs replacement. Contact us to purchase a handheld monitor or call our service team to complete this test.
  4. Test from Lead Wire Termination: If initial testing at the cable head shows normal readings, proceed to test from the point where the lead wire terminates inside the cable node. Failure to obtain readings here indicates a defective lead wire, which should be replaced promptly. Call your Account Rep to order a replacement or count on your service crew to place the order and schedule the installation of the updated materials.
  5. Check for Channel Issues: If all components and wiring appear intact, investigate potential channel problems. Move the temp/moisture cable to a different position on the cable node connector terminal. Unmap and remap the corresponding cable node in your OPI BLUE account. Check if the cable appears on the new channel:
    • If successful, associate the “new” cable with the intended position.
    • If unsuccessful, contact support for further troubleshooting steps, which may include replacing the cable.

By following these systematic troubleshooting steps, you can effectively diagnose and resolve issues with non-responsive moisture cables in your grain management system. Ensuring timely maintenance and replacement of faulty components is essential for maintaining optimal grain storage conditions and maximizing operational efficiency
