FEATURES OF THE LC11 SERIES DUAL INPUT CONTROLLER:

The LC11 Series is designed to receive signals from two liquid sensors. It turns its internal relay ON or OFF
(as set by the invert switch) in response to the presence of liquid on both sensors, and changes the relay
status back again when both sensors are dry.
Automatic Empty:
Latch is ON & Invert is OFF. Relay will energize when level reaches high switch (both switches are wet).
Relay will de-energize when level is below the bottom switch (both switches are dry).
Automatic Fill:
Latch is ON & Invert is ON. Relay will energize when level is below the bottom switch (both switches are dry).
Relay will de-energize when level reaches high switch (both switches are wet).
The LC11 Series may be used with almost any kind of sensor signal: current sensing or contact closure. The
relay is a single pole, double throw type; the controlled device can be connected to either the normally open or
normally closed side of the relay. A time delay from 0 to 60 seconds can be set before the relay responds to
the sensor input. Typical applications for the LC11 Series are automatic filling (starting fill pump at a low level
and stopping pump at a high level) or automatic emptying operations (opening a drain valve at a high level and
closing valve at low level).
