Bin Level Sensor Calibration
Capacitive Bin Level Sensors
The Raven OmniSeed system utilizes capacitive low bin level sensors to ensure products are available in each
bin for the seeding operation.
Note: The field computer monitors the capacitive low bin level sensors for low bin alarm conditions. If the
field computer does not display an alert, the low bin level sensors may require recalibration.
It is recommended to check the low bin level sensors on occasion and recalibrate the sensors as necessary. To
calibrate the low bin level sensors:
FIGURE 2. Capacitive Low Bin Level Sensor
1. With an empty bin, check that the sensor status LED is off.
a. If the LED is on and the bin is empty, check the sensor inside the bin and clean as necessary.
b. If the LED is still on, adjust the sensitivity set screw until the LED extinguishes.
2. Fill the bin to a level to cover the bin level sensor. If the LED illuminates after the bin is filled, no further
adjustment is required.
It may be possible to fine tune the sensor for the specific crop, however, the following steps are only
necessary should the low bin level sensor sends intermittent or false alarms during seeding operations.
3. With the sensor covered, the sensor LED should be on.
a. If the LED is off, adjust the sensitivity set screw until the LED illuminates. Turn the sensitivity set screw
an addition quarter to half turn.
b. If the sensor displays intermittent or false bin level alarms during operation, adjust the sensitivity set
screw until the status LED is extinguished. Reverse the set screw a quarter to half turn and verify the
status LED is illuminated.
