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. -

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. -

Page 8: Features Of The Lc10 Series Single Input Controller
Getting Started Step Four FEATURES OF THE LC10 SERIES SINGLE INPUT CONTROLLER: The LC10 Series are designed to receive a signal from a single liquid sensor. It turns its internal relay ON or OFF (as set by the invert switch) in response to the presence of liquid, and changes the relay status back again when the sensor is dry. -
Page 9: Features Of The Lc11 Series Dual Input Controller
Getting Started Step Four 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. -

Series only) to the lower pair. Note the polarity: (+) is a 13.5 VDC, 27 mA power supply (to be connected to the red wire of a Flowline sensor), and (-) is the return path from the sensor (to be connected to the black wire of a Flowline sensor). -
Page 11: Wiring
(series LZ12, LU10, LP15, LP50 & LO10 series) will be wired with the Red wire to the (+) terminal and the Black wire to the (-) terminal. FLOWLINE mechanical reed switches (series LV10, LV2_, LV3_, LV4_, LH2_ & LH3_ series) will have a particular wiring based upon part number. See the illustration below to indicate wiring for your switch. -
Page 12: Strobe Alert Output
Wiring Step Five STROBE ALERT OUTPUT: While wired NO, Strobe Alert can be used as a high or low level alarm, depending on the setting for the invert switch. The Strobe Alert can also be wired NC. Note: Strobe Alert needs to be powered. Since the relay is a true dry contact, power will need to be added. -
Page 13: Installation
The LC10 & LC11 Series are a cost-effective, modular liquid level controller whose body incorporates a female 3/4" NPT (3/4" R) fitting, allowing it to be mounted directly onto any Flowline sensor or any 3/4" connection. Simply provide its required AC power and a controlled device such as a valve, pump, or alarm that can be switched by the controller’s relay in response to the sensor input. -
Page 14: Application Examples
Application Examples Step Seven LOW LEVEL ALARM: The goal is to make sure that an operator is notified if the liquid level falls below a certain point. If it does, an alarm will sound, alerting the operator of a low level. A level switch must be mounted at the location where the alarm will sound. -
Page 15: Pump Protection
Application Examples Step Seven PUMP PROTECTION: The key here is to install a level switch just above the outlet to the pump. As long as the switch is Wet, the pump can operate. If the switch ever becomes Dry, the relay will open preventing the pump from running. -
Page 16: Automatic Empty
Application Examples Step Seven AUTOMATIC EMPTY: Similar system logic can be used for an automatic empty operation. In this example, we will use a pump to empty a tank. The system still consists of a tank with a high level sensor, a low level sensor, and a pump that is controlled by the controller. -
