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.

(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
