SAFETY PRECAUTIONS INTRODUCTION

About This Manual: PLEASE READ THE ENTIRE MAN-

UAL 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 flow controller with a Strobe
Alert™. Many aspects of installation and use are similar between
the three models.

User’s Responsibility for Safety: FLOWLINE manufac-

tures 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 compo-

nents 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: Sensor mount

controllers should not be used with explosive or flammable liq­uids, which require an intrinsically safe or classified area 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 hous-

ing 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 10 amp resis-

tive 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-energized 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.

Sensor-mount controllers: The LC30 is 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 Switch Pak™ 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.

Features of the LC30 Single Input Controller: The

LC30 Controller is designed to receive a signal from a single flow
switch. It turns its internal relay On or Off (as set by the invert switch)
in response to the presence of flow or no-flow, and changes the relay
status back again when the sensor reverses. The LC30 may be used
with any FLOWLINE N-channel flow or level switch. The relay is a
single pole, double throw type; the controlled device can be connect­ed to either the normally open or normally closed side of the relay. A
time delay from 0 to 60 seconds can be set before the relay responds
to the sensor input.

Typical applications for the LC30 are flow or no-flow switch/alarm
operations (activating an alarm at no-flow).

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. Invert switch: This DIP switch reverses the logic of the relay

control in response to the sensor(s): conditions that used to ener­gize the relay will make it turn off and vice versa.

6. Time Delay: After the input(s) change(s) state, this control sets

a delay from 0.15 to 60 seconds before the relay will respond.

7. Input 1: This amber LED will light immediately whenever the

appropriate sensor attached to the terminals detects liquid, and
will turn off when it is dry.

8. Input terminals: Connect the wiring from the sensors to these

terminals. Note the polarity: (+) is a 13.5 VDC, 100 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). (S) is the Relay signal input to be con­nected to the white wire with the Green wire returning to the (-)
terminal.

3/4" NPT Mounting Thread:

Installation of the compact relay controller takes advantage of the
3/4" NPT thread located on its base. This makes the controller fully
compatible with any of Flowline's level switches or Smart Trak™ or
Switch Pak™ mounting systems.

Always tighten the controller
from the wrench flat located
on the swivel base. Never
tighten from the body of the
controller.

Switch Cable:

When installing a Flowline flow switch,
adjust the cable away from the printed cir­cuit boards in the controller body. Avoid
breaking the seal between the top of the
level switch and the plastic coated cable.

Connecting switches to input terminals:

Please note a difference between FLOWLINE flow switches. All flow
switches (models FT10-___5 and GT10-___5) will be wired with the
Red wire to the (+) terminal, the Black wire to the (-) terminal and the
White wire to the (S) terminal. 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.

INSTALLATION APPLICATION EXAMPLES

Relay Input Wiring: The relay is a single pole, double throw

type rated at 250 Volts AC, 10 Amps, 1/4 Hp. The two terminal NO
and NC (normally open and normally closed) will be used in different
applications. Remember that the "normal" state is when the relay coil
is de-energized and the Red relay LED is Off / de-energized.

Strobe Alert Output

With the Strobe Alert wired NC, it can be used as a high or low level
alarm, depending on the setting for the invert switch. Strobe can also

be wired NO.

Changing from 120 to 240 VAC

1. Remove the two screws from the top of the printed circuit board
(PCB) and gently slide the PCB from the housing. Use caution when
removing the PCB.

2. Located jumpers JWA, JWB and JWC on the PCB.

3. To change to 240 VAC, remove jumpers from JWB and JWC and
place a single jumper across JWA. To change to 120 VAC, remove
jumper JWA and place jumpers across JWB and JWC.

4. Gently return PCB into housing and replace the two screws.

120 VAC 240 VAC

Configuration Configuration

Low Flow Alarm: The goal is to indicate when the flow rate falls

below a certain point. If it does, an alarm is supposed to sound, alert­ing the operator of a low flow condition.

If power is accidentally cut to the controller, the sensor's ability to
notify the operator of a low flow condition could be lost. The system
must alert the operator not only to low flow, but to controller power
loss.

To do this, connect the hot lead of the
alarm to the NC side of the relay ter­minal of the controller. If power is
lost, the relay will be de-energized,
and the alarm will sound (if there is
still power to the alarm circuit itself).
The alarm circuit should have a non­interruptible power supply or some
other indicator or backup alarm to

warn of a power failure in the alarm circuit.
In this application, the normal status is when the sensor is in the flow

condition, and the relay will be energized holding the alarm circuit
open. Please note that the flow switch can be wired either normally
closed or normally open (Step 5). When the switch is wired NC, the
input LED will be off and the relay LED will be on. So for this appli­cation, Invert should be set to the On position. When the switch is
wired NO, the input LED and the relay LED will be on simultaneous­ly. So for this application, Invert should be set to the Off position.

LED Indication:

Use LED's located above the input terminals to indicate whether the
switch is in a flow or no-flow state. When the switch is wired NC,
Amber indicates no-flow and Off indicates flow. Reversing the polar­ity (Normally Open), Amber indicates flow and Off indicates no-flow.

FLOW SWITCH CALIBRATION TROUBLESHOOTING

Controller Logic: For all controllers, please use the following

guide to understand the operation of the FLOWLINE LC30 con­troller.

1. Power LED: Make sure the Green power LED is On when

power is supplied to the controller.

2. Input LED: For NC switch wiring, the input LED on the con-

trollers will be Amber when the switch reads no-flow and Off
when the switch reads flow.

3. Invert Operation: When the input LED turn Off and On, the

relay LED will also switch. With invert Of f, the relay LED will be
On when the input LED is On and Off when the input LED is Off.
With invert On, the relay LED will be Off when the input LED is
On and On when the input LED is Off.

4. Relay Operation: The relay may be wired either NO or NC.

The normal state of the relay is when its LED is Off. With the
LED On, the relay is in the energized mode and all terminal con­nections are reversed.

Cleaning Procedure:

1. Power: Make Sure that all power to the sensor, controller and/or

power supply is completely disconnected.

2. Sensor Removal: Make sure that the flow is off and the pres-

sure is down prior to removing the Switch-Pro™. Carefully, remove

the sensor from the installation. Replace the sensor with a 3/4” NPT
plug to insure that liquid does not leak out during this procedure. Do

not re-install the flow switch if the threads are damaged.

3. Cleaning the Sensor/Controller: Use a soft bristle brush and

mild detergent, carefully wash the flow switch and controller. Do
not use harsh abrasives such as steel wool or sandpaper, which
might damage the surface sensor. Do not use incompatible sol­vents which may damage the sensor’s PP/Ryton or PVDF plastic
body or the PP and Polycarbonate body of the controller..

4. Installation: Follow the appropriate steps of installation as out-

lined in the installation section of this manual.

Set Points: If the preset factory calibration is not adequate for

your application, follow the calibration steps listed below. Note: the
switch's internal LED will be on when the switch detects no-flow and
will off when the switch detects flow.

1. Install the fitting and flow switch as described in the Installation
section of this manual. Turn the flow switch and controller power
on and adjust the flow rate to the application setting. If the medi­um to be sensed is likely to be subject to high temperature varia­tions, the flow switch should be set at the highest normal temper­ature likely to be encountered.

2. Locate the potentiometer knob at the top
of the flow switch. The red LED is visible
through the potentiometer. (If the LED is
on, slowly adjust the potentiometer coun­terclockwise, with a small flat head
screwdriver until the LED turns off.) The
adjustment is a single turn 270° poten­tiometer. The initial response time of the
flow switch after adjustment is 1 to 10
seconds. Adjust the potentiometer in slow
increments and wait for the response.

If the LED is off, slowly adjust the poten­tiometer clockwise until the light turns on.
Then turn the potentiometer counterclockwise to bring the LED
off at a reliable setting. Remember, adjust the potentiometer in
slow increments and wait for the response.

3. Verify that the new calibration is correct by lowering the system
flow rate below the set point and check to see that the red LED
turns on. Then increase the flow rate above the set point and ver­ify that the red LED turns off accordingly.
