Low Level Cutoff

LLC6 Series
Liquid Level Control

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 xed time delay of 1 to 60 s and is available in input voltages of 24, 120, or
230 V AC. LED indicator illuminates whenever the LLC6’s 10 A 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. 24 V AC and 120 V AC units are recognized as
limit switches under UL353 (230 V AC units are UL508) and CSA certied 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 xed
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 xed 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.
