A - Tailings Sensors

If tailings sensor display consistently reads full (all bars lit) when not harvesting or empty (no bars lit) when harvesting, it may indicate that the sensor lens is coated with material or seal under lens has allowed dust to enter.

Tailings sensor is a Class 1 laser product and emits laser radiation when powered. When servicing or removing tailings sensors, use caution and do not view beam directly.

Key switch must be turned OFF and tailings sensor must be unplugged before servicing or removing sensors.

DO NOT operate sensor with lens removed. Accessible laser emission when the lens is in place:

  • 850 nm
  • 500 nsec pulse width
  • ≤ 500 Hz rep rate
  • < 90 nJ per pulse
  • 43 uW average power
  • Class 1 levels (Eye Safe)

Accessible laser emission levels if sensor was operated with lens removed are:

  • 850 nm
  • 500 nsec pulse width
  • ≤ 500 Hz rep rate
  • < 380 nJ per pulse
  • 188 uW average power
  • Class 3R Levels (small potential for eye injury)
  1. Remove tailings sensors (A) to inspect and clean lenses if needed.
  2. If lenses are clean, remove and check for dust. If dust is found, clean area and reassemble the lens onto the unit making sure that gasket is sealing.
  3. Verify that lens is retained with all previously removed screws prior to installation.

    Failure to install plastic cover prior to replacement of sensors on elevator may cause malfunction, incorrect harvest readings, or sensor damage, and could allow for potentially hazardous eye exposure when sensor is removed.

  4. Install sensor and test system.
  5. If display continues to read full or empty, contact your John Deere dealer.
