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.
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.
