The LLC4 series combines resistance-sensing circuitry with solid-state timing to provide single-probe level maintenance. On adjustable units, the sensitivity adjustment allows accurate level sensing while ignoring foaming agents and floating debris. Isolated 12 V ac is provided at the probe to prevent electrolysis. A trickle current of less than 1 mA determines the presence or absence of conductive liquid between the probe and common. The LLC4 series can be used with many types of low voltage (resistance changing) transducers to perform other control functions like temperature limit control, photo limit control, condensation sensing, and ice sensing. This unit features an industry standard, eight-pin octal plug connection.

Funktionsweise

Drain (pump-down mode): When the liquid level rises and touches the probe, the time delay begins. This time delay prevents rapid cycling of the output relay and its load. At the end of the time delay, the output relay energizes and remains energized until the liquid level falls below the probe level. The output relay de-energizes and remains de-energized until the liquid rises and touches the probe.

Fill (pump-up mode): When the liquid level falls below the probe, the time delay begins. This time delay prevents rapid cycling of the output relay and its load. At the end of the time delay, the output relay energizes and remains energized until the liquid level rises and touches the probe. The output relay then de-energizes and remains de-energized until the liquid level again falls below the probe level.
