SAFETY PRECAUTIONS INTRODUCTION

About This Manual:

PLEASE READ THE ENTIRE MANUAL PRIOR TO
INSTALLING OR USING THIS PRODUCT. This manual
includes information on three different models of Remote Relay
Controllers from FLOWLINE: LC40-1001, LC41-1001 and LC42-

1001. Many aspects of installation and use are similar between the
three models. Where they differ, the manual will note it. Please
refer to the part number on the controller you have purchased as
you read.

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 preformed by qualified personnel in
accordance with all applicable national, state and local electrical
codes.

Flammable or Explosive Applications:

LC40 series remote mount controllers should not be used with
explosive or flammable liquids, which require an intrinsically
safe rating such as the FLOWLINE LC90 series. 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 controller housing is not designed to be immersed. It should
me mounted in such a way that it does not come into contact with
liquid. Its case is made out of PP (polypropylene). 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 10 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 10 amp rating does not
provide an ample margin for such inrush currents.

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-ener gized 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 build
up 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.

Step Four Step Five

GUIDE TO CONTROLS INSTALLATION

1. Power indicator:This green LED lights when AC power is ON.

2. Relay indicator: This red LED will light whenever the con-

troller energizes the relay, in response to the proper condition at
the sensor input(s) and after the time delay.

3. AC Power terminals: Connection of 120 VAC power to the

controller. The setting may be changed to 240 VAC if desired.
This requires changing internal jumpers; this is covered in the
Installation section of the manual. Polarity (neutral and hot) does
not matter.

4. Relay terminals (NC, C, NO): Connect the device you wish to

control (pump, alarm etc.) to these terminals: supply to the COM
terminal, and the device to the NO or NC terminal as required.
The switched device should be a noninductive load of not more
than 10 amps; for reactive loads the current must be derated or
protection circuits used. When the red LED is ON and the relay is
in the energized state, the NO terminal will be closed and the NC
terminal will be open.

5. Time delay: Use potentiometer to set delay from 0.15 to 60 sec-

onds. Delay occurs during switch make and switch break .

6. Input indicators: Use these LEDs for indicating W et or Dry sta-

tus of switch. When switch is Wet, LED will be Amber. When
switch is dry, LED will either be Green for powered switches or
Off for reed switches. Note: Powered switches may be reversed
for Wet/Off, Dry/Amber indication.

7. Invert switch:This switch reverses the logic of the relay control

in response to the switch(es): conditions that used to energize the
relay will now de-energize the relay and vice versa.

8. Latch switch (LC41 and LC42): This switch determines how

the relay will be energized in response to the two sensor inputs.
When LATCH is OFF, the relay responds to sensor Input Aonly;
when LATCH is ON, the relay will energize or de-energize only
when both switches (Aand B) are in the same condition (both wet
or both dry). The relay will remain latched until both switches
change conditions.

9. Input terminals: Connect the switch wires to these terminals:

Note the polarity: (+) is a 13.5 VDC, 27 mA power supply (con­nected to the red wire of a FLOWLINE level switch), and (-) is
the return path from the sensor (connected to the black wire of a
FLOWLINE level switch). If polarity is reversed, the sensors will
not work.

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.

Connecting switches to input terminals:

Please note a difference between FLOWLINE powered level switch­es and reed switches. All powered level switches (models LO10,
LP10, LP15, LP50, LU10, LZ10) will be wired with the Red wire to
the (+) terminal and the Black wire to the (-) terminal. FLOWLINE
reed switches (models LV10 and LH10) will have a particular wiring
based upon part number. See the illustration below to indicate wiring
for your switch. Note: the Shield wire will be used only for long cable

runs or where excessive electrical noise is present.

LED Indication:

Use LED's located above the input terminals to indicate whether the
switch is in a wet or dry state. With powered switches, Green indi­cates dry and Amber indicates wet. With reed switches, Amber indi­cates wet and no LED indicates dry. Note: reed switches may be
wired in reverse so that wet indicates dry and Amber indicates dry.
