Not Detecting Liquid Level
• Ensure that the liquid level detector cable is plugged in.
• Check if liquid is detectable. Liquid level detection works only if there is electrical conductivity in your liquid. Liquid level
detecting will not work with most non-polar liquids. For intermediate polarity liquids and polar liquids, check the sensitivity
setting in the 223 Setup Utility.
• Check that the liquid level sensing switch is in the correct position. Follow the liquid level detector cable to where it is
plugged in. The liquid level sensing switch is to the right of the connector. Make sure the switch is in the right position.
