2.4. Sensors
2.4.1. The sensors are capacitance-based sensors and detect changes in state. For this reason it is
important to keep the sensors free from loose objects coming in contact with them. Do not leave any
papers or have any loose clothing hanging near the sensors. Doing so can cause false readings.
2.4.2. The sensors will come calibrated to the standard containers for each position; a plastic carboy for
the water waste and uncoated glass containers for the remaining positions. If containers of any other
type of material are used the sensor should be calibrated for that material to ensure proper
response.
2.4.3. Sensor Calibration
• For sensors located in the body of the Smart Bottle Rack remove the panel screws from the top of the
unit using a 1/8" Allen wrench. For sensors located in the tower remove the side panels screws using a
1/8" Allen wrench.
• Place the empty container of the material to be calibrated in the appropriate section of the Smart
Bottle Rack.
• Ensure that the orange head of the capacitive sensor is flush with the container.
• Using a long pointed tool (such as a #1 screwdriver) press and hold the sensor “OFF” button for at least
2 seconds, but no more than 6. Confirm that the sensor indicator light is blinking slowly. Release the
button and verify that the light is off.
• Fill the container above the level of the sensor with the same fluid that will be in use in that
container, i.e. methanol, water, or hexane in the appropriate containers or approximately 2%
methanol in water in the waste container.
• Ensure that the orange head of the capacitive sensor is flush with the container.
• Using a long pointed tool (such as a #1 screwdriver), press and hold the sensor “ON” button. Confirm
that the orange sensor indicator light is blinking slowly. When the indicator light changes from slow
blinking to a quick blinking (approximately 6 sec) the ON state calibration is complete.
• Reattach the panels.
