capacitance-based level sensing. Fill control and alarm functions are provided, front panel programmable from 0 to 100 percent of the active sensing length. Two independent control band setpoints, "A" and "B", activate a power receptacle on the rear panel. When the liquid level drops below the "B" setpoint, the power receptacle is energized and remains energized until the liquid level rises to the "A" setpoint. The Model 186 also provides a fail-safe timer feature that automatically de-energizes the power receptacle once a user programmed maximum time interval of up to 600 minutes is reached. "High" and "Low" alarm setpoints to activate front panel LED warning indicators and rear panel relay outputs (for remote alarming) in the event of an overfill or liquid loss condition. The "Low" level alarm also energizes an audible warning which can be silenced from the front panel. The Model 186 is ideal for unattended systems where automated fill is required.
