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. |

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.

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.

1 SAFETY
Safety First – Before Working on this Equipment
CAUTION This equipment is designed to be installed in association with volatile hydrocarbon liquids such as gasoline and diesel fuel. Installing or working on this equipment means working in an environment in which these highly flammable liquids or vapors are present. This presents a real risk of severe injury or death if these instructions and standard industry practices are not followed.
Prohibit access to the work area to certified and trained installers/service personnel
Identify and mark the perimeter of the work area with signs, safety-cones and colored safety tape
Prevent unauthorized vehicle access (block access) into the work areas by using barriers, barricades, and service trucks
Use only non-sparking tools when working in these Hazardous Areas
Occasionally check for presence of hydrocarbon vapors in containment sumps
ELECTRICAL DANGER Lethal Electrical Shock Hazard! Before installing, servicing, or working on this equipment: turn off all submersible pump power / pump controller power, Tank Sentinel console power, LS300 electronic Line Leak Detector console power, and dispenser power at the electrical power panel(s). Lock out and tag these circuit breakers in the off position to prevent accidental / unauthorized circuit breaker closure. Failure to turn off and lock out power would result in severe injury or death!
WARNING Highly flammable vapors may be present in the environment where this equipment is installed or serviced. DO NOT smoke while working on or near this equipment and only use nonsparking tools. Failure to follow this instruction could result in a serious fire or explosion.
WARNING Follow all federal, state, and local laws governing the installation of this product and the entire system. When no other regulations apply, follow NFPA 30, 30A, and 70 from the National Fire Protection Association. Failure to do so could result in serious property damage, environmental-contamination, and severe injury or death.
ELECTRICAL DANGER Verify that no voltage exists before working-on, or wiring-to circuits described in this manual, otherwise lethal electrical-shock-hazards could exist, which may cause injury or death. Note: circuit breaker contact(s) can fail to open even when the circuit breaker lever indicates off.

LS300 User’s Guide
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.
DANGER
FIRE, EXPLOSION &
ELECTRICAL SHOCK HAZARD
Electronic line leak detector installed—the pump may start at any time and pressurize the fuel lines.
•BEFORE performing any installation or service — turn off/ lock out electrical power sources to the submersible pump(s), and
relieve fuel-line pressure.
INCON PN 240-1175 Rev. D
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.

LS300 User’s Guide
WARNING Prevent static electric sparks and possible explosions — always have fuel test container on the ground when filling with gasoline. Use only containers approved for motor fuel storage.
CAUTION Refer to all applicable Federal, State, City and local codes, your National
Electric Code (NEC), and the Automotive and Marine Service Station Code (NFPA 30A in the USA) before installation or maintenance. This installation is designed for submersible pumps which have a Pump Control box in the station. If a pump control box does not exist, then the system must be retrofitted to add a pump control box in the facility to comply with Codes.
CAUTION Although the LSU300 is water resistant, INCON does not recommend operating the LSU for long periods while under water. Drain the sump and manhole immediately into a holding tank for disposal per Codes.
WARNING Highly flammable vapors may be present in the environment in which this equipment is being installed or serviced. Do not smoke while working on or near this equipment. Use only non-sparking tools. Failure to follow this instruction could result in a serious fire or explosion.
CAUTION Before entering a containment sump check for the presence of hydrocarbon vapors, if vapor levels are unsafe ventilate the sump with fresh air. While working in the sump periodically check the atmosphere in the sump, if vapors reach unsafe levels exit the sump and ventilate it.
CAUTION ALWAYS have a second person standing by for assistance when working in or around a containment sump. Electronic and electrical petroleum monitoring equipment is often housed in containment sumps designed to trap hazardous liquid spills and prevent contamination of the environment.
WARNING These containment sumps can trap dangerous amounts of hydrocarbon vapors.
If these vapors are inhaled they could cause dizziness or unconsciousness. If the vapors were ignited they could explode causing serious injury or death.
ELECTRICAL DANGER ALWAYS lock out and tag electrical circuit breakers while installing or servicing this equipment, pumps and related equipment. A potentially lethal electrical shock hazard and the possibility of an explosion or fire from a spark can result if the electrical circuit breakers are accidentally turned on during installation or servicing. During normal operation Auto-Learn will turn on the STP as part of its leak testing process. A shock, fire or environmental contamination hazard could result from Auto-Learn attempting to turn on the STP while equipment is being serviced.

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

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.
