SAFETY PRECAUTIONS Step Three
About This Manual: PLEASE READ THE ENTIRE MANUAL PRIOR TO INSTALLING OR USING THIS PRODUCT.
This manual includes information on two different models of Compact Relay Flow Controllers from
Flowline: LC30‐10_1 and LC30‐10_2. The LC30‐10_1 is a single‐input flow controller and the LC30‐10_2 is a
single‐input controller with a Strobe Alert™ flash alarm. Many aspects of installation and use are similar
between the two 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 LC30 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 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.
