P.1 GENERAL OVERVIEW
Note: This section is provided strictly as an overview of the LLP203 and associated console.
Please refer to the appropriate sections of this manual for detailed explanations, instructions and
cautions.
The LLP203 is an EPA-compliant(40CFR280.44(a)) line leak detector intended for use with
pressurized liquid piping systems, and is ideal for Critical Power applications where 3 GPH(11 LPH)
catastrophic line leak detection with audible and visual alarms is required, but pump shutdown is not
desired, but can be optionally programmed. The LLP203 is designed to be directly compatible with
all TMS2000, TMS3000 and TMS4000 Tank Management Systems built after 2003 using
Pneumercator’s standard, universal leak sensor inputs. Note that some systems may require a simple
firmware upgrade to support the LLP203.
The LLP203, in conjunction with a TMS console, operates on the principle of pressure decay over
time to detect a 3 GPH leak. The parameters that govern the timing for leak detection are determined
solely by the volume, charge pressure and bulk modulus(elasticity) of the piping system, and
accordingly, are independent of piping descriptions such as “rigid”, “semi-rigid”, and “flex”. Note that
in all cases, leak detection applies only to the section of piping between the pump check valve and
the outlet shutoff valve, which must hold pressure following supply pump shutdown. The system offers
three methods of calibration, MANUAL, CALCULATED and AUTO CAPTURE, described as follows:
MANUAL: The discharge time from charge pressure down to 10 PSI is measured using a
Pneumercator LG203 or similar 3 GPH leak generating device, and entered into the system, in
seconds.
CALCULATED: The volume, charge pressure and bulk modulus are enteredinto the system. Note
that if this method is used, a 3 GPH test must still be run to verify proper detection.
AUTO CAPTURE: A Pneumercator LG203 or similar 3 GPH leak generating device is installed,
and the system automatically detects pump start, pump stop, and captures the decay time. This
feature is only available on TMS4000/4000M series consoles.
The system offers two methods for triggering a line leak test. Following Pump Shutdown monitors
pump activity and performs a line test when pump shutdown is detected. Following Pump Shutdown
or Hourly monitors pump activity and performs a line test when pump shutdown is detected, or hourly
if no pump activity. This second mode requires the programming of a system relay to control the
pump.
Important Notes:
Each product line must be tested and verified free of leaks prior to installing LLP203 sensors, and
all must be tested upon startup, 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.
The LLP203 Sensors are Intrinsically Safe and are for use only with the TMS2000, TMS3000,
and TMS4000. The Intrinsically Safe wiring requires separation from non-intrinsically safe circuit
wiring as per Article 504 of the National Electric Code.
This Installation and Owner’s Manual provides instructions for site assessment and preparations,
installation, wiring, configuration, and operation. Each section gives step-by-step instructions to
successfully complete the section. A troubleshooting guide is included if difficulties are encountered.

P.2 SITE SURVEY & ASSESSMENT
A precision line test must be conducted before installing the LLP203 transducer for the first time
and before replacing any line leak detector that indicates a leak to assure line integrity.
USE A PRESSURE GAUGE TO VERIFY THAT EACH LINE IS STABLE. THE PRESSURE
CHANGE WITHIN THE PIPELINE AFTER 5 MINUTES OF Pump-OFF MUST BE LESS THAN 5
PSI. The TMS cannot be accurately calibrated unless the product is stable in pipeline.
A minimum static line pressure of 20 PSI is required for the LLP203 to perform a Gross (3 GPH)
line leak test.
Check that the pipeline volume, combined with the Piping Bulk Modulus and Charge Pressure, is
less than or equal to the 3rd party approval (see table on Page 35). The TMS/LLP203 is Third
party approved for use in pressurized pipelines up to 1179 gallons (4463 liters).
Before installation of sensor, verify that the equipment is proper for the site.
P.3 MATERIALS & TOOLS REQUIRED

SECTION 1 – SAFETY
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 represents a 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
CAUTION
You MUST check with local authorities for shut-down guidance when using any
line leak detector on an emergency generator system. Life-
Safety systems do not
allow system shut-down, only audible and visual alarms.
Before installing, servicing, or working on this equipment: turn off all pump
power/pump controller power, TMS system power, and dispenser power at
the electrical Service Panel(s). Lock out andtag these circuit breakers in the
off position to prevent accidental/unauthorized circuit breaker closure.
Failure to turn off and lock out power may result in severe injury or death.
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 non-sparking tools. Failure to follow these instructions
could result in a serious fire or explosion.
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.
The TMS may start pumps automatically to pressurize the line being tested.
Automatic pump starts occur hourly after the pump stops. Before performing
any installation or service (such as replacing fuel-filters) – tag and lock-out
all electrical power sources to the 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.

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.
Multiple PNEUMERCATOR Caution stickers are supplied with
each LLP203. 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 LLP203 (at the 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.
The fuel line from the pump to the output valve, may be under pressure. Turn
off all pump power and relieve pipeline pressure (reference and follow the pump
manufacturer’s directions). If the LLP203/plug (or any other part of the 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.
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.
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.
During the AUTO CAPTURE process, ALWAYS secure the LG203 in the
appropriate container. When the pump is turned on, a fine stream will be
sprayed out the orifice of the LG203. This stream can cause movement of the
LG203 and possibly come out of the container. This product stream can cause
physical injury and environmental hazards.
Prevent static electric sparks and possible explosions — always have fuel
container on the ground when filling with fuel. Use only containers approved for
petroleum.
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. The TMS may
provide a pilot relay to control the load relay for the Pump. Be sure to follow all
applicable codes to ensure the safe operation of the Pump.
Although the LLP203 is water resistant, PNEUMERCATOR does not
recommend operating the LLP203 for long periods while under water. Drain the
sump and manhole immediately into a holding tank for disposal per Codes.

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.
ALWAYS have a second person standing by for assistance when working in or
around a containment sump. Electronic petroleum equipment is often housed in
containment sumps designed to trap hazardous liquid spills and prevent
contamination of the environment.
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.
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, the TMS may turn
on the Pump as part of its leak testing process. A shock, fire or
environmental contamination hazard could result from attempting to turn on
the Pump while equipment is being serviced.
Petroleum is carcinogenic – use adequate protection to avoid health hazards.
ALWAYS cleanup and dispose of used absorbent/rags and petroleum resistant
gloves in approved waste containers. Cleanup refuse and dispose of these
immediately to avoid personnel injury from vapors or direct skin contact to also
avoid possible fire or environmental safety hazards.
The LLP203 is designed for use in specific applications and in compliance with
industry standards and practices. Using it in applications for which it was not
designed or failure to follow industry standards and practices may cause the
product to malfunction or fail.
Contact Pneumercator for applications requiring over 5500 feet (1676 Meters)
of cabling. Lengths exceeding 5500 feet may cause unreliable system
operation, which may result in creation of environmental hazards in the event
that a leak is undetected.

SECTION 2 – MECHANICAL INSTALLATION
2.1 LLP203 INSTALLATION
The LLP203 Line Leak Pressure Sensor is intended to be installed in the 2” Leak Detector Port
of the Pump. Refer to Pump manufacturer’s instructions for port location.
1. At the electrical Service Panel: lock-out & Tag POWER OFF for the Pump, Pump Controller,
and Dispensers.
A TMS equipped with an LLP203 may start pumps automatically to run leak tests
at full line pressure. Automatic pump starts occur hourly 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 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.
Avoid personnel injury or property damage: ALWAYS secure the hazardous
work area from moving vehicles. This equipment may bemounted 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.
2. Relieve pipeline pressure to 0 PSI per pump manufacturer’s recommendation and capture
any product that escapes or use absorbent rags to clean up any product spills and dispose of
properly.
The fuel line from the 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). If the LLP203, plug (or any other part of the 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.
3. Remove other in-line leak detection equipment before installing the LLP203.
4. Apply Petroleum resistant, non-hardening, UL Classified, FEP Pipe Dope/Thread Sealant
(Hercules Megaloc, Gasoila, etc.) to the threads of the LLP203 Transducer and use a 2-3/8”
open-end wrench to install it in the Leak Detector Port of the Pump housing (See Figure 2-1).
5. Install Couplings, threaded Rigid Metal Conduit (RMC), and Junction Boxes (J-Boxes) in the
Pump sumps.
6. Install threaded RMC and Electrical Y Seal (EYS) fittings along with Sensor Field Cabling
(Belden 8442) from TMS console to the J-Boxes.

7. After all LLP203 Line Leak Pressure Sensors have been installed, check that the system is
ready to be pressurized to check for the absence of leaks.
8. After the installation is checked and all personnel are clear, have the electrician turn on power
at the Service Panel for the Pump (Submerged Turbine Pumps and Output Devices).
9. Turn on the Pump at the output device (do not transfer product) and check for leaks at each
Sump. If there are any leaks, immediately turn off power, lockout and tag at the Service Panel,
use absorbent rags to clean up the product spills and dispose of properly, and repair the
leak(s) and repeat step 8 and 9 until no leaks remain.
10. Clean areas where the Caution Labels will be placed so the adhesive backing will stick to a
dry surface that is clean and free of petroleum.
11. Cleanup and dispose of installation materials, petroleum absorbent and waste material in
appropriate containers.
12. Apply the supplied Caution Labels to clean dry areas near Dispenser Fuel Filters, Pump
Controllers, and on the Cable of the LLP203 Transducer and on the Pump housing.

Follow the instructions below to wire the LLP203 Line Leak Sensor to the TMS. A licensed
electrician is recommended and may be required to perform the electrical installation.
1. All cabling from the LLP203 transducer to the TMS console must be separated from
non-intrinsically safe wiring as per Article 504 of the National Electric Code.
Avoid personnel injury or property damage: ALWAYS secure the hazardous
work area from moving vehicles. This equipment may be 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.
2. At the electrical Service Panel: lock-out & tag POWER OFF for the Pump, Pump Controller,
and Dispensers.
Hook inputs are 120/240 VAC. Disconnect all high Voltage sources before
accessing internal electronics.
A TMS equipped with the LLP203 may start pump automatically to run a leak
test at full line pressure. Automatic pump starts may occur between periods of
product dispensing when no product is being dispensed. BEFORE performing
any installation or service (such as replacing fuel-filters) – tag and lock-out
all electrical power sources to the 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.
3. If not done during Mechanical Installation, Section 2, run 2-conductor cable (Belden 8442)
from each Junction Box near the Pump where the LLP203 Transducer is installed, to the TMS

Refer to the Table at the beginning of this Section to identify the relationship between
the LLP203 Sensor Input, CC Input, and optional Relay Outputs. Both the wiring and
TMS configuration must be consistent with this Table.
Wire LLP203 transducers only to TMS consoles in accordance with applicable
standards including Article 504 of the National Electric Code.
5. Wire LLP203 Transducers to the corresponding Sensor Input channels inside the TMS
console.
a. Strip insulation from the ends of each conductor so that no insulation will enter the
terminal block and minimal wire exposure exiting the terminal block.
b. Wire Transducers. Make sure all wires are fully inserted and clamped at the terminal
block. Make sure no stray strands of wire are shorting to adjacent terminal block
connections.
6. Connect Dry Contact Pump Running Signal for each LLP203, typically provided via CS-10
Current Sensor, to the corresponding Contact Closure (CC) Input. Refer to the following two
pages for an illustrated example. Note that this connection is shown with a heavy black line.
7. Connect Pump Control Relay Output for each LLP203 configured to perform an Hourly Test.
Refer to the following two pages for an illustrated example. Note that this connection is shown
with a blue line.
8. As needed, connect Pump Shut Off Relay Output for each LLP203. Note that there are two
methods available for support Pump Shut Off:
•Pump Disabled with TMS powered off: Wiring connected to Normally Open
Relay Terminals in TMS with Relay configured with a Normal Contact State
of ON
•Pump Enabled with TMS powered off: Wiring connected to Normally
Closed Relay Terminals in TMS.
Refer to the following two pages for an illustrated example. Note that this connection is shown
with a red dashed line.

SECTION 4 – TMS CONFIGURATION
4.1 LINE LEAK MODE, 3 GPH
The TMS supports two modes of operation that affect the frequency of the line leak test. Each mode
is described below, including all TMS connection requirements:
Note: The Line Leak Mode should be set prior to addressing any other LLP203 settings.
•Follow Pump Off: Performs line leak test every time the pump stops after running for at least
30 seconds. Failure is reported after a single test fails.
Connection Requirements:
o1 CC Input: Dry Contact Signal representing the pump running status.
•Follow Pump Off and Hourly:Performs line leaktest every time the pump stops after running
for at least 30 seconds and every hour thereafter. Failure is confirmed after three consecutive
failed tests performed in rapid succession.
Connection Requirements:
o1 CC Input: Dry Contact Signal representing the pump running status.
o1 Relay Output: Activates pump for 30 seconds, as needed.
