General Overview

The TS-LS300 Auto-Learn® Line Leak Detector (LLD) is a precision electronic line-leak-detection
system that is produced for installation in a petroleum pumping system. The Auto-Learn Line Leak
Detector automatically monitors at certain times and will indicate pipeline leaks should a leak occur.
An alarm indicator lights, an audible alarm horn sounds, and positive pump shutdown happens when
a leak is detected. This complies with U.S. EPA requirements 280.41(b) & 280.44(a) for automatic
leak detection in pressurized piping. After installation, the user of the leak detector must monitor the
system to ensure that any leak alarm and pump shutdown (indicating a leak in the pipeline) is dealt
with promptly.

The Auto-Learn LLD can detect a leak from the STP check valve to the solenoid valve at the
dispenser, assuming no other Normally Closed valve is in the pipeline system. The Auto-Learn LLD
does not detect leaks from the fuel storage tank or the from the submersible pump before the output
check valve. The Auto-Learn LLD is used with motor fuels.

The system includes a 2 or 4 channel LSU300 console with stick-on Product ID Labels, Danger
Labels, one Auto-Learn Calibration Kit (leak-generator), 2 to 4 Needle Valve Kits, no-splice
connectors, and 2 to 4 LSU300 pressure-transducers as specified at time of order. Each channel will
monitor one piping system or product line. All line leak detectors must be tested upon start-up, and
routinely thereafter (at least annually) under NFPA standards. These NFPA and other industry
testing practices must be followed by the installer and the end user. A leak detector is not a
substitute for compliance with prudent industry practices. Fuel inventory reconciliation checks must
be performed on a daily basis by comparing dispenser meter totalizers with fuel volume changes in
the underground tank.

The Auto-Learn LLD pressure transducer is manufactured in two different versions:

1) The TS-LSU300 pressure transducers are Intrinsically Safe (I.S.) for U.S. and
international markets and are for use only with the TS-LS300 version console

2) The TS-LSU300E pressure transducers are Explosion Proof for Canadian and
U.S. markets and are for use only with the TS-LS300E version console

Wire Intrinsically Safe LSU300 transducers only with TS-LS300 consoles... physical
separation of transducer cables from non-intrinsically safe circuits is also required.

NOTE

Wire Explosion Proof LSU300E transducers only with TS-LS300E consoles in accordance
with applicable standards... use of explosion proof J-Boxes and conduit fittings in hazardous
locations. This wiring does not require separation from other non-intrinsically safe circuit wiring. This

method can be used for retrofit installations where separate conduit is not available.

This Installation and Owner’s Manual gives instructions for, site assessment and preparations,
installation, wiring, calibration, and operation. Each section gives step by step process to
successfully complete the section. A troubleshooting guide is included if difficulties are encountered.

P

Page P-2 PREFACE

LS300 User’s Guide

Each product line must be precision tested and verified free of leaks before any component of the
LS300 system is installed. After verification, the LS300 Auto-Learn

®

system is installed, wired, and
calibrated. The supplied leak-generating device/calibration kit* is attached to a needle valve, and the
appropriate line channel selector switch is placed in the learn position at the console. Each line is
calibrated separately, one at a time, to “learn” the parameters and characteristics of a line with a
known induced leak-rate.

At each STP housing, the needle valve kits* are assembled and installed in the pressure test ports,
and the LSU300 pressure-transducers are installed in 2 inch NPT line leak detector ports (LSU300
cable length must not exceed 500 feet).

After a line is calibrated the leak-generator device is moved to the next product line for Auto-Learn
calibration. The entire process is repeated until all lines are separately calibrated and the console is
left in the Run – Detect mode.

The front panel has a power on light and 4 status-lights per line. The status lights show currently
running line leak tests, faults, and alarms. Fault-alarms will cause indicator lights to blink or flash.
Certain alarms will also activate the internal alarm horn. Manual line leak tests may be started and

* The needle valve kit and the leak generating device/calibration kit have not been
evaluated by Underwriters Laboratories

Site Survey & Assessment

A precision line test must be conducted before installing the LSU300 transducer for
the first time and before replacing any line leak detector that is indicating a leak to
assure line integrity .

Before installation of Auto-Learn system verify that the equipment is proper for the
site.

Check that the pipeline volume (based on length, internal diameter, and pipe type)
is less than the 3rd party approval (see Table P-2). Third party tests have approved

PREFACE Page P-5

the use of Auto-Learn in rigid pipelines up to 163-gallon capacity and in flex
pipelines up to 39.5 gallons.

TABLE P-2 Third Party Approved — Max Pipe Lengths:

Pipe Diameter I.D.

Max. Rigid Pipe

Lengthl

Max. Flexible Pipe

Length

NOTE

Maximum pipe lengths are equivalent to: 163 gallons (617 liters) in rigid piping

systems and 39.5 gallons (149.5 liters) in flexible piping systems.

A minimum static line pressure of 17.5 psi is needed for Auto-Learn LLD to perform
a Gross (3gph) and Monthly (0.2 gph) line-leak test. If the static line pressure is
greater than 17.5 psi but less than 22.5 psi, the Annual (0.1 gph) line-leak test can
not be performed.

For each pipeline verify that the pressure is 25 psi or greater when the pump is
“ON,” and that the pressure holds at 22.5 psi or greater when the pump is “OFF.”

Use a pressure gauge to verify that each line is stable after 5 minutes of pump-off.
The pressure change in a stable pipeline must be less than 5 psi.

NOTE

To maintain proper pipeline pressure with a FE Petro STP, use FE Petro’s standard check valve.
With Red Jacket STP, use the adjustable functional element with pressure adjusted to meet the
Auto-Learn LLD pressure requirements. For proper operation of the Red Jacket functional element
the pump “ON” pressure must be at least 2 psi greater than pump “OFF” line pressure. See Red

Jacket instructions for complete details before starting.

ELECTRICAL DANGER

Electronic line leak detectors start submersible pumps

automatically to run leak-tests at full line pressure. Automatic pump starts occur between
periods of product dispensing when there is no product being dispensed. Before performing

any installation or service (such as replacing fuel-filters) – tag and lock-out all electrical power
sources to the submersible pump(s), pump controllers, and dispensers

and relieve fuel-line pressure.
Failure to turn off power and relieve fuel-line pressure before work is started can result in:
pressurized fuel spills (an environmental hazard associated with costly clean-ups), and fire or
explosion hazard that may result in injury or death.

NOTE

Multiple INCON Danger stickers are supplied with electronic line
leak detectors. Apply these stickers on the pump relay box
cover, in locations near dispenser fuel-line filters, plugs,
emergency safety-shut-off valves, on or near the Leak Sensing
Unit Transducer (at the submersible pump housing), and other
serviceable components of a fuel line (where a spill would
occur if the line became pressurized). The selected surfaces
must be clean, dry, and in plain sight so that the label can be

read, and followed.

WARNING

The fuel line from the submersible pump to the dispenser, may be under
pressure. Turn off all pump power and relieve pipeline pressure (reference and follow the
pump manufacturer’s directions about how to do this). If the line leak detector/plug (or any
other part of the submersible pump and fuel line) is removed without first relieving pressure,
then a product leak will occur. This could cause an environmental, fire, or explosion hazard,
and may result in injury or death.

WARNING

Avoid personnel injury or property damage: keep moving vehicles and
unauthorized personnel out of the hazardous work area. Use Safety Cones, Barricades,
Warning Signs, and Safety Tape, and block access with Barricades / service trucks to the
work area to avoid injury or property damage.

WARNING

Be careful not to cause sparks when working on fuel dispensing equipment
(volatile fuel may be within the pump’s leak detector port). Allow no source of combustion
near the work area. Failure to follow these directions may cause an explosion hazard, which
could result in property damage and death.

WARNING

During the Calibration/learn process, ALWAYS secure the line leak generator in
the appropriate container. When the submersible pump is turned on, a fine stream will be
sprayed out the orifice of the line leak generator. This stream can cause movement of the line
leak generator and possibly come out of the container. This product stream can cause
physical injury and environmental hazards.

2 Mechanical Installation

Mechanical Installation Sequence:

Follow the instructions here to mount the LS300 Auto-Learn console and to install the LSU300 Leak
Sensing Unit transducers, and Needle Valves at each STP containment sump (see Figure 2.2 for
typical finished installation). Be sure to ask the electrician to do any “electrical” type of work when
appropriate.

1.) Mount the LS300 Console on a vertical surface using appropriate fasteners, level, and between 2
feet (0.6 m) and 6 feet (1.9 m) high for use (see Figure 2-1 and make allowances for conduit runs
and fittings at the left, right and bottom sides)

NOTE

The LS300 AutoLearn console must be located in a pollution degree 2 environment per IEC60664 in
contries requiring CE compliance.

2.) At the electrical power panel: locked-out & Tag POWER OFF for the STP’s, Pump Controllers, and
Dispensers

at full line pressure. Automatic pump starts occur between periods of product dispensing when there
is no product being dispensed. BEFORE performing any installation or service (such as

replacing fuel-filters) – tag and lockout all electrical power sources to the submersible
pump(s), pump controllers, and dispensers and relieve fuel-line pressure. Failure to turn off
power and relieve fuel-line pressure before work is started can result in: pressurized fuel
spills (an environmental hazard associated with costly cleanups), and fire or explosion hazard
that may result in injury or death.

WARNING

from moving vehicles. This equipment is usually mounted underground, therefore, reduced visibility
puts service personnel working on this equipment in danger from moving vehicles entering the work
area. Use Safety Cones, Barricades, Warning Signs, and Safety Tape, and block access with
Barricades / service vehicles to the work area to avoid injury or property damage.

Electronic line leak detectors start submersible pumps automatically to run leak-tests

Avoid personnel injury or property damage: ALWAYS secure the hazardous work area

3.) Relieve pipeline pressure to 0 psi per manufacturers recommendation and capture any product that
escapes or use absorbent rags to clean up any product spills and dispose of properly (FE Petro
Pumps: open Manual Pressure Relief valve / MPR valve... Red Jacket Pumps: Turn Functional
Adjustment element to 0 psi, if no adjustment exists – remove and replace with an adjustable
functional element)

WARNING

Turn off all pump power and relieve pipeline pressure (reference and follow the pump manufacturer’s
directions about how to do this). If the line leak detector/plug (or any other part of the submersible
pump and fuel line) is removed without first relieving pressure, then a product leak will occur. This
could cause an environmental, fire, or explosion hazard, and may result in injury or death.

The fuel line from the submersible pump to the dispenser, may be under pressure.

4.) Remove other in-line leak detection equipment before installing the LSU300 Auto-Learn LLD

5.) Apply UL Classified Gasoline/Oil resistand teflon pipe dope thread sealant to the threads of the
LSU300 Transducer and use a 2-3/8 inch open-end wrench to install it in the Leak Detector Port of
the STP housing (see Figure 2-2)

6.) Apply UL Classified Gasoline/Oil resistand teflon pipe dope thread sealant, assemble, and install the
supplied Needle Valves in the Line Pressure Test Port of the STP and close all Needle Valves (see
Figure 2-2)

7.) Install Couplings, threaded Rigid Metal Conduit (RMC), and Explosion/Weather Proof Junction
Boxes (J-Boxes) in the STP sumps (see Figure 2-2).

8.) Install threaded RMC and EYS fittings along with Transducer Cables (Belden #9365) from LS300
console to the Explosion/Weather Proof J-Boxes (have the licensed electrician splice the cables
together. If this wiring is Intrinsically Safe it MUST NOT be run with any Explosion Proof wiring or
other non-Intrinsically Safe wiring!).

9.) After all LSU300 Leak Sensing Units (transducers) have been installed, check to see that all Needle
valves are closed, and that the system is ready to be pressurized to check for the absence of leaks.

10.) After the installation is checked and all personnel are clear, have the electrician turn on power at the
Power Panel for the STP (Submerged Turbine Pumps and Dispensers).

11.) Turn on the STP at the dispenser (do not deliver product) and check for leaks at each Sump... if
there are any leaks, immediately turn off power, lockout and tag at the Power Panel, use absorbent
rags to clean up the product spills and dispose of properly, and repair the leak(s) and repeat step 10
and step 11 until no leaks remain.

13.) Clean areas where the Danger Labels will be placed so the adhesive backing will stick to a dry
surface that is clean and free of petroleum.

14.) Cleanup and dispose of installation materials, petroleum absorbent and waste material in
appropriate containers.

15.) Stick the supplied Danger Labels (PN: 240-1175) to clean dry areas near
Dispenser Fuel Filters, Pump Controllers, and on the Cable of the
LSU300 Transducer and on the STP housing.
