Harvest - Dashes on Display or Weight Stuck

If pairing to the Libra Cart device was successful, but the display tab is showing dashes or the displayed weight is stuck, ensure each of the following: 

  1. The app is running the latest version from the Apple App Store or Google Play. 
  2. The device is listed under Paired Devices in the Settings tab of the app. If the device is listed, but there is no checkmark beside the cart / device name, tap the name to reconnect. If there is a checkmark beside the cart / device name, delete the device by swiping left on the cart name, tap Delete, and try to pair again (doing this will not delete any existing data).
  3. Bluetooth is enabled on the mobile device.
  4. Disconnect the load cell cable from the Libra Cart device. If a weight reading (random weights) appears on the Display tab after disconnecting, this may indicate a short or an issue with a load cell(s). Inspect all wiring and junction box connections and check for any cabling that has been rubbed, damaged, or pinched.
  5. Check the sticker on the lid of the box, if it does not say Libra Cart you will need to download and pair with the appropriate app. If the lid sticker is illegible, you can check the model number listed on the sticker on the side of the box. If it is M0050 or M0051, you will need to download and pair to the Libra Express app. For Libra Express support see HERE.
  6. Primary Display is selected in the Settings tab for the main mobile device in the grain cart. If using a remote display, ensure that the primary display is paired and communicating. 
  7. The calibration settings appear normal in the Devices tab.
  8. The battery inside the Libra Cart device is well seated with correct polarity and does not need replacing. For Libra Cart models M0013, M0014 and M0016, a small green light next to the battery terminal will flash once every 10 seconds if the Libra Cart device is getting power. If using the power cable, inspect the cable and ensure it is secured to the Libra Cart device.
  9. There is no moisture or corrosion on the circuit board and all wires are connected inside the Libra Cart device. 

If re-pairing is successful, but the issue is persisting, try the following: 

  1. On the mobile device (under general Bluetooth settings), turn Bluetooth OFF and then ON. 
  2. Turn airplane mode ON and then OFF on the mobile device. 
  3. Restart the mobile device. 
  4. Remove the battery, wait a full 60 seconds and then re-insert. 
  5. Try another compatible mobile device.
