Description

The LLC6 Series is a plug-in, single-probe conductive liquid

level control designed for low liquid level cutoff protection. It

offers a factory fixed time delay of 1 - 60s and is available in

input voltages of 24, 120, or 230VAC. LED indicator illuminates

whenever the LLC6’s 10A, SPDT output relay is energized.

Available with automatic/manual reset or a special manual reset

with power outage feature, which auto resets the unit when

power is restored and the water level is acceptable. 24VAC and

120VAC units are recognized as limit switches under UL353

(230VAC units are UL508) and CSA certified under Standard 14.

Operation

Automatic Reset (Reset terminals not connected): When

liquid rises to the low level cutoff probe, the output relay and

the LED indicator energize. When the liquid falls below low level

cutoff probe, the output relay and the LED indicator de-energize

after a fixed time delay.

Manual Reset (Reset switch connected): When the liquid

level falls below the low level probe, the output relay and LED

de-energize after a fixed time delay. When the liquid level rises

to the low level probe, the output relay and LED indicator remain

de-energized until the manual reset switch is opened; then they

energize immediately.

Power Outage Manual Reset (Reset switch connected): A

power outage causes the output relay and LED indicator to

de-energize. Upon restoration of power, if the liquid level is

above the low level probe, the output relay and LED indicator

will re-energize. If the liquid level is below the low level probe,

the output relay and LED indicator remain de-energized until the

Normally Closed (NC) reset switch is opened.
