Description

The LLC2 Series is a dual-probe conductive liquid level control

designed for OEM equipment and commercial appliance

applications. Models are available for fill or drain operation.

Transformer isolated 12VAC is provided at the probes to prevent

electrolysis. A trickle current of less than 1mA determines the

presence or absence of liquid between the probes and common.

On adjustable units, the sensitivity adjustment allows accurate

level sensing while ignoring foaming agents and floating debris.

The LLC2 Series printed circuit board is conformal coated to

resist moisture and corrosion.

Operation

Drain (Pump-Down Mode): When the liquid level rises and

touches the high probe, the output relay energizes and remains

energized until the liquid level falls below the low probe. The

output relay then de-energizes and remains de-energized until

the liquid again touches the high probe.

Fill (Pump-Up Mode): When the liquid level falls below the low

probe, the output relay energizes and remains energized until

the liquid level rises and touches the high probe. The output

relay then de-energizes and remains de-energized until the liquid

level again falls below the low probe.

FEATURES BENEFITS

Isolated 12VAC probes Prevents scale buildup on the probes

Open PCB design Cost effective design for OEM equipment and

commercial appliances

Conformally coated PCB Protects against moisture and corrosion

Sensitivity adjustment Provides accurate level sensing while ignoring foam

or floating debris
