Description

The LLC5 provides dual probe conductive liquid level control

in a convenient octal plug-in package. Models are available

for fixed fill or drain operation. Isolated, pulsed DC voltage

on the probes prevents electrolytic plating. Less than 1 mA

of current is used to sense the presence of conductive liquid

between the probes and common. On adjustable units, the

sensitivity adjustment eliminates false tripping caused by

floating debris and foaming agents.

Operation

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

and touches the high level probe, the output relay and LED

energize and remain energized until the liquid level falls below

the low level probe. The output relay and LED de-energize and

remain de-energized until the liquid rises and touches the high

level probe.

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

the low level probe, the output relay and LED energize and

remain energized until the liquid level rises and touches the

high level probe. The output relay and LED de-energize and

remain de-energized until the liquid level again falls below the

low level probe.

FEATURES BENEFITS

Unique Probe

Protection logic

Probes are protected from scale build up through

pulsed DC signal between the probes.
