Introduction / Table of Contents Step One
The LC10 & LC11 Series Controllers
are general-purpose level controllers offered in two configurations for
pump and valve control. The LC10 Series features a single 16A SPDT relay output and can accept one level
sensor as an input. This package has an optional flashing alarm and is ideal for high level or low level
alarm/control. The LC11 Series features a single 16A SPDT latching relay output and can accept one or two
level sensor(s) as an input. This package is ideal for the automatic filling or emptying of a tank. Package this
level controller with our liquid level switch sensors and fittings.
FEATURES
Fail-Safe relay control of pumps, valves or alarms with a 0 to 60 second delay
Optional flashing alarm brings immediate attention to level alarm conditions.
Polypropylene enclosure rated NEMA 4X with swivel base for conduit alignment.
Easy setup with LED indicators for sensor(s), power and relay status.
Invert switch changes relay state from NO to NC without rewiring.
AC powered

Safety Precautions Step Three
About This Manual: PLEASE READ THE ENTIRE MANUAL PRIOR TO INSTALLING OR USING THIS
PRODUCT. This manual includes information on three different models of Compact Relay Controllers from
Flowline: LC10 and LC11 Series. The LC10 series is a single-input controller with an optional Flash Alarm
and the LC11 Series is a dual-input controller. Many aspects of installation and use are similar between
the three models.
User’s Responsibility for Safety: FLOWLINE manufactures several models of controller, with different
mounting and switching configurations. It is the user’s responsibility to select a controller model that is
appropriate for the application, install it properly, perform tests of the installed system, and maintain all
components.
Electrical Shock Hazard: It is possible to contact components on the controller that carry high voltage,
causing serious injury or death. All power to the controller and the relay circuit(s) it controls should be
turned OFF prior to working on the controller. If it is necessary to make adjustments during powered
operation, use extreme caution and use only insulated tools. Making adjustments to powered controllers is
not recommended. Wiring should be performed by qualified personnel in accordance with all applicable
national, state and local electrical codes.
Flammable or Explosive Applications: Sensor mount controllers should not be used with explosive or
flammable liquids, which require an intrinsically safe or explosion proof rating. If you are unsure of the
suitability of a controller for your installation, consult your Flowline representative for further information.
Install In a Dry Location: The LC10 & LC11 Series controller housing is liquid-resistant and made of
Polypropylene (PP). When installed properly, the controller is not designed to be immersed. It should be
mounted in such a way that it does not normally come into contact with fluid. Refer to an industry
reference to ensure that compounds that may splash onto the controller housing will not damage it. Such
damage is not covered by the warranty.
Relay Contact Rating: The relay is rated for a 16 amp (12 amp – CE version) resistive load. Many loads
(such as a motor during start-up or incandescent lights) are reactive and may have an inrush current
characteristic that may be 10 to 20 times their steady-state load rating. The use of a contact protection
circuit may be necessary for your installation if the 16 amp rating does not provide an ample margin for
such inrush currents.
Safety Cover: Based upon the part number selected, a safety cover has been placed within the enclosure.
Always replace the safety cover after any service.

Safety Precautions Step Three
Make a Fail-Safe System: Design a fail-safe system that accommodates the possibility of relay or power
failure. If power is cut off to the controller, it will de-energize the relay. Make sure that the de-energized
state of the relay is the safe state in your process. For example, if controller power is lost, a pump filling a
tank will turn off if it is connected to the Normally Open side of the relay.
While the internal relay is reliable, over the course of time relay failure is possible in two modes: under a
heavy load the contacts may be “welded” or stuck into the energized position, or corrosion may buildup on
a contact so that it will not complete the circuit when it should. In critical applications, redundant backup
systems and alarms must be used in addition to the primary system. Such backup systems should use
different sensor technologies where possible.
While this manual offers some examples and suggestions to help explain the operation of FLOWLINE
products, such examples are for information only and are not intended as a complete guide to installing any
specific system.
