Page 2: Table Of Contents
Introduction / Table of Contents Step One The LC40, LC41 & LC42 Series Controllers are general-purpose level controllers offered in three configurations for pump and valve control. The LC40 Series features a single 10A SPDT relay output and can accept one level sensor as an input. The LC41 Series features a single 10A SPDT latching relay output and can accept one or two level sensor(s) as an input. -

Page 7: Features Of The Single Input High Or Low Alarm Relay
Getting Started Step Four FEATURES OF A SINGLE INPUT HIGH OR LOW RELAY: Single Input Relays (LC40 series, LC41 series with latch turned OFF and LC42 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 8: Features Of The Dual Input Automation Fill/Empty Relay
Getting Started Step Four FEATURES OF A DUAL INPUT AUTOMATIC FILL/EMPTY RELAY: The Dual Input Automatic Fill/Empty Relay (LC41 and LC42 series only) 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. -

Input terminals: Connect the switch wires to these terminals: Note the polarity: (+) is a 13.5 VDC, 30 mA power supply (connected to the red wire of a FLOWLINE powered level switch), and (-) is the return path from the sensor (connected to the black wire of a FLOWLINE powered level switch). With powered level switches, if the wires are reversed, the sensor will not work. -
Page 10: Wiring
Wiring Step Five CONNECTING SWITCHES TO INPUT TERMINALS: Please note a difference between FLOWLINE powered level switches and mechanical reed switches. All powered level switches (series LZ12, LU10, LP15, LP50 & LO10 series) will be wired with the Red wire to the (+) terminal and the Black wire to the (-) terminal. -
Page 11: Relay And Power Terminals
Wiring Step Five RELAY AND POWER TERMINALS Depending on the model selected, there will be either one or two relays. The label for the relay applies for both relays. Each terminal has a Normally Open (NC), Common (C) and Normally Open (NO) terminal. The relay(s) is(are) a single pole, double throw (SPDT) type rated at 250 Volts AC, 10 Amps, 1/4 Hp. -
Page 12: Installation
Installation Step Six PANEL DIN RAIL MOUNTING: The controller may be mounted by either a back panel using two screws through mounting holes located at the corners of the controller or by snapping the controller on 35 mm DIN Rail. Note: Always install the controller in a location where it does not come into contact with liquid. -
Page 13: Application Exmaples
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 14: 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. To prevent relay chatter, add a small relay delay. -
Page 15: 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. -
