Warning

Danger

Caution

Follow all applicable codes governing the installation and servicing of this product and the entire system. Always lock out and tag electrical circuit breakers while installing or servicing this equipment and any 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. Please refer to the Installation and Owner’s Manual for this equipment, and the appropriate documentation for any other related equipment, for complete installation and safety information.

Follow all federal, state and local laws governing the installation of this product and its associated systems. When no other regulations apply, follow NFPA codes 30, 30A and 70 from the National Fire Protection Association. Failure to follow these codes could result in severe injury, death, serious property damage and/or environmental contamination.

Always secure the work area from moving vehicles. The equipment in this manual is usually mounted underground, so reduced visibility puts service personnel working on this equipment in danger from moving vehicles entering the work area. To help eliminate these unsafe conditions, secure the area by using a service truck to block access to the work environment, or by using any other reasonable means available to ensure the safety of service personnel.

When the Tank Sentinel system is used to monitor tanks containing gasoline or other flammable substances, you may create an explosion hazard if you do not follow the requirements in this manual carefully.

All wiring must enter the Tank Sentinel console’s enclosure through the designated knockouts. An explosion hazard may result if other openings are used.

All wiring from probes or sensors to the Tank Sentinel console must be run in conduit separate from all other wiring. Failure to do so will create an explosion hazard.

Substituting components could impair intrinsic safety. The Tank Sentinel 5 (T5) series consoles are intrinsically safe for sensors installed in – Class I, Division 1, Group D – hazardous locations. Substitution of components could make the energy limiting circuitry in the system ineffective and could cause an explosion hazard. Repairs to a T5 Series console or attached components should only be performed by a qualified, factory-trained technician.

OverviewThe TS-LS500 is a continuous product line leak detection system that monitors the primary pipe. This product is an available option of Franklin Fueling Systems’ T5 Series Fuel Management System consoles.The TS-LS500 system includes the FMS application running on a T5 series console using a 4-20 mA input module and a transducer. One transducer, which monitors line pressure, is required per product line. Line Pressure is created by the pump and static seating pressure is metered by a pressure relief valve. Transducers (TS-LSU500) use the AutoLearn technology to continuously evaluate the line conditions. Note: The TS-LS500 requires pressure for leak tests and should only be installed in systems that are designed to obtain and hold this minimum static pressure (refer to Site Requirements table below). The system may report “learned with errors” if tests are run at less than optimum pressure.

ApplicationsThe following diagram illustrates a typical installation of the LS500 equipment inside of a STP sump.

Figure 1: LS500 Install OverviewTo maintain optimal line pressure, Franklin Fueling makes the following recommendations for submersible pumps:• For FE Petro Submersible Pumps, use a Standard Check Valve (part # 400988931).• For Red Jacket Submersible Pumps, use an adjustable functional element, adjusting the pump OFF pressure to be at

least 2 psi below the pump ON pressure.Newer style Red Jacket Submersible Pumps do not have an adjustable functional element as an option. These submersible pumps have a check valve that meets the LS500 pressure requirements.Note: The TS-LSU500 is a pressure sensing device that can be installed anywhere in the product pipeline where accurate line pressure can be monitored. When installing in a location other than the mechanical leak detector port, consider the location of in-line check valves, solenoid valves, or any other equipment that can affect the line pressure being monitored.If an anti-siphon valve is installed at the discharge of the submersible pump, the TS-LSU500 transducer should be installed downstream of the valve to insure proper line pressure monitoring.

Transducer Installation1. Apply UL Classified Gasoline / Oil resistant pipe thread sealant to the threads of the transducer and use a 2 3/8”

open-end wrench to install it in the Leak Detector Port of the STP housing (see Figure 1).

Note: When using TS-LS500 line leak detection in a manifolded line application, you only need to use one transducer to monitor the entire line. This transducer should be located in the master STP. In-line check valves should NOT be used as the line leak detection will not be able to test beyond them. Please see the STP manufacture about appropriate check and / or relief valves.

2. Install Couplings, threaded Rigid Metal Conduit (RMC), and Explosion / Weather Proof Junction Boxes (J-Boxes) in the STP sumps. For intrinsically safe wiring, run the transducer lead to the junction box. For explosion-proof installations, run conduit to the top of the transducer.

3. Install threaded RMC and EYS fittings along with Transducer Cables (Belden #9365) from LS500 console to the Explosion / Weather Proof J-Boxes. A licensed electrician should 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! Alpha cable #58411 must be used if using nonmetallic (PVC) conduit as allowed by local code.

LS-500 Setup (Console Programming)The following instructions are a guide to programming the LS-500 only. The administrator password will be necessary to save the programming changes. For instruction on FMS programming, or how to obtain the Administrator access level, please refer to the T5 Series FMS Programming Guide (p/n 000-2142) or the TS-550 / 5000 evo FMS Programming Guide (p/n 000-2173).

Access the T5 Series FMS console (via the LCD touch screen or by the web) and navigate to the Setup Menu, Go to each of the following parameters, shown in the next tables, and set them accordingly per the site. You will be prompted to enter the Administrator password when it is required.

Note: Site setups vary depending on the products used and other equipment installed. Setup information in the sections of this chapter depicts a typical site and are meant as examples only.

AC Input ModuleOne of the functions of the AC input module is to accept incoming dispenser hook signals. The hook signal tells the console which product the dispenser is requesting, then turns the appropriate Submersible Turbine Pump (STP) on using either a relay (from the relay board or from the power supply board) or the turbine pump interface (TPI). The LS500 is constantly monitoring the pressure on the line, and testing accordingly. To perform tests properly, the LS500 needs to know when the pumps are being used by other applications.

Pre-Operational LS500 TestingThe line stability test procedure assumes that all STP’s, pump controllers, and AC inputs have been installed, wired, calibrated and are operational and in accordance with their respective installation and operation procedures. It also assumes that all T5 Series FMS console programming has been completed accurately.

CautionDO NOT proceed to the Learn Process until each line successfully completes pre-operational testing. Failure to perform this test or ignoring any failed tests may prevent the FMS application from detecting a line leak.

Note: State and / or local laws may require a separate, more stringent manual line tightness test. Before installing the LS500, ALWAYS verify and comply with local regulations.

Note: The STP connected to the line being tested will need to be activated by lifting the appropriate product dispenser handle. Verify that all STP’s and pump controllers are installed, calibrated and operational.

Note: The lines must be able to reach 20 PSI. If the lines cannot reach 20 PSI, the issue needs to be resolved or the LS500 will not work in that STP.

Required Equipment• LS500 3.0 GPH Leak Generator Kit (TSP-ALCAL)

• Needle Valve Kit (TS-ALNIP)

• Pressure gauge

• Approved safety container

ATTENTION.

The Needle Valve Kit (TS-ALNIP) included with this kit is NOT compatible with E85 and other fuels containing high levels of Ethanol / Alcohol.For E85 and other high Ethanol / Alcohol mixture applications the Alternative Fuels Needle Valve Kit (TS-AFALNIP) should be ordered separately.All other regularly wetted components are E85 compatible.

Line Stability TestPerform the following steps for each line.

1. Install the needle valve kit, pressure gauge and leak generator into the STP manifold. Pressurize the line by lifting the dispenser handle without dispensing fuel.

2. Once the line is pressurized, turn the STP off and monitor the pressure on the pressure gauge. The pressure should not change more than 5 PSI (34.5 Kpa) in 5 minutes.

3. If the pressure does change, pressurize the line again by lifting the dispenser handle (do not dispense), and check again.

4. If it does not change more than 5 PSI in 5 minutes proceed to the learn process. If the pressure changes more than 5 PSI pressurize the lines again, and re-test.

Purging the lineIf air is in the system, the lines must be purged of the air. If needed, this procedure should be done before the Line Stability Test or Learning the line.

Purge the line by dispensing from each fueling point starting with the dispenser furthest from the tank. The STP should be running the full time that the line is purged.

17

Learn ProcessEach line must be learned before the FMS system can continuously monitor it. Learning involves bleeding the line pressure down to zero, with no air in the line, then introducing a calibrated leak, facilitated by the leak generating kit (TS-ALCAL). The system learns this pressure decay curve and uses it to compare test data during continuous operation to determine if there is a leak in the line.

Note: All console programming must be completed prior to the learn process. Refer to the Setup (Console Programming) chapter in this manual for details. Administrator privileges are necessary to Learn Lines. Refer to T5 Series FMS Programming Guide (p / n 000-2142) or the TS-550 / 5000 evo FMS Programming Guide (p/n 000-2173). for information on gaining Administrator privileges.

Note: Complete the Pre-Operation Line Testing chapter prior to starting the Learn Process.

Note: No dispensing can take place during the Learn Process. If product is dispensed while Learning, stop the process by pressing the Stop button.

Note: DO NOT submerse or block the TS-ALCAL orifice while learning the line. The orifice MUST be kept free of dirt and debris.

When to Learn / Re-Learn• Line installation and start-up

• After repairs or modifications that effect the operating or holding pressure of the line• After 4-20mA Input Module replacement• After certain 4-20mA Input Module firmware upgrades (consult FFS Technical Services Department)• If moving the LS-500 to another 4-20mA channel

Figure 4 – Leak Generator KitsProcedure

1. The needle valve kit (TS-ALNIP) and 3.0 GPH Leak Generator (TSP-ALCAL) should be installed in the STP manifold. The line must be purged of all air prior to learning the line.

2. Open the needle valve with the leak generator in an approved container to catch any product. Let the line pressure bleed down to 0. Make sure that the pressure reads 0 on the pressure gauge installed on the needle valve kit.

3. Navigate to the line control screen on either the touch screen or by the web page. Locate the learn section and press start.

4. If the learn process is performed correctly the screen will show the events in the following sequence, • Learning zero offset • The system turns on the STP to learn pump pressure • Learn the pressure decay curve

5. When finished, the message Learn Completed – No Errors is displayed on-screen and the Not Learned indicator will become inactive.

Note: Each line is different, but if the pump takes an excessively long time to bleed down to 0 PSI, then there may be air in the system. Re-purge the line and if air remains, look for pathways that air could have been introduced.

Note: If any errors are encountered at any time during the Learn Process, the screen will display the applicable error message and the Not Learned indicator will remain active. Refer to the Alarms chapter of this guide for information on troubleshooting any errors that are displayed.

6. Once the line has been successfully learned, the line will automatically be enabled. Leave the leak generator open. The console will automatically begin a gross leak test. If the line was learned properly it will detect the leak and positive shutdown will occur after the 2nd failed 3 GPM test (Approximately 10 minutes). The console’s screen updates will indicate if the line is failing a gross test.

7. Close the needle valve. To clear the alarm, navigate to the line control screen and choose reset alarm. The console will ask: Do you also want to enable this line? Select OK. (If you select CANCEL the line will not be enabled) This will automatically start another gross line test. A 3 gph pass will allow the FMS to continue to monitor the line. If this test fails, isolate why the test failed, make necessary repairs, and then reset the alarm again.

8. Remove the leak generator and replace the leak generator plug. The needle valve kit should be left installed in the manifold to easily allow functional testing, and re-learning lines if needed.

LS-500 ReportsLine test reports are available on demand from the console or using the web page. The reports can also be generated by using the rules engine. Several report options are available to print or save generated reports. For more information on reports in general, please refer to either the T5 Series Programming Manual (p / n 000-2142) or the T5 Series Operator’s Guide (p / n 000-2151) or the TS-550 / 5000 evo FMS Programming Guide (p/n 000-2173).

LS-500 Line Leak ReportsLS-500 Line Leak Reports include any line tests completed within the date range chosen by the user. An example of an LS-500 report can be found below.

AlarmsWhen a T5 FMS console is in alarm, the Alarm LED on the front of the console will flash. If the line has been programmed to shut down the pump on failed test (in the FMS Setup), the pump will be unavailable for all system tests and dispensing until the line with the active alarm is manually reset. If the condition still exists after reset, the alarm will return. A service visit may be required to identify and correct the condition.

Warning Always REMOVE POWER from the console prior to installing/removing a module or performing any maintenance while the console door is open.

Note: Refer to the Important Safety Messages outlined in the beginning of this manual before performing any console maintenance.

Note: If this guide is not able to help you correct a Warning or Alarm, please contact FFS Technical Services (1-800-984-6266).

Clearing AlarmsClearing a console of alarms is important because, depending on how the T5 Series FMS console has been set up, alarms can: disable channels, start an annunciator, or stop a line test under way.

Administrator privileges will be necessary to clear line alarms on the T5 Series FMS console. For instructions on how to obtain an Administrator access level, please refer to the T5 Series FMS Programming Guide (p/n 000-2142) or the TS-550 / 5000 evo FMS Programming Guide (p/n 000-2173).

1. Identify the alarm on the FMS Alarms screen.

2. Diagnose the condition using information found in the Alarms chapter of this guide.

3. Follow the troubleshooting steps in the previous section of this chapter to correct the issues indicated by the alarms.

4. Navigate to the Line Control screen.

5. Select Reset Alarms on the Control screen.

6. Select Enable/Disable on the Control screen if you were not given the choice to enable the line when the alarms were reset.

If the condition still exists, the alarm can take up to several hours to reappear after the line is enabled.

LS-500 Functional TestingPerform a Functional Test annually. This test will verify that the LS-500 application will detect and alarm on a leak condition. This test should be performed during times when there is no dispensing.

1. If the channel is Enabled, disable the channel. At the T5 Series FMS console (via LCD or by the web page), navigate to the FMS > Lines Control screen. Press the Enable / Disable button to disable the line.

2. Remove the plug in the needle valve kit on the manifold. Connect the TS-ALCAL (Leak Generator Kit) to this port.

3. Open the needle valve.

4. Enable the line. This will initiate a gross line test.

5. Verify that the console displays a gross line test fail. This can take up to 10 minutes.

Note: The system must run two separate tests five minutes apart and fail them both before a hard alarm occurs.

6. The channel will be disabled by the FMS application. Remove the TS-ALCAL. Replace and tighten the plug.

7. At the T5 Series FMS console (via LCD or by the web page), navigate to the FMS Lines Control screen. Press the Reset Alarm button to clear the alarm and enable the channel.

8. Select OK when prompted.

9. If the Annual Functional Test passed by properly detecting the leak, please skip this step. If the system did not catch the leak and the test failed, disable the channel and run the pre-operational tests. Perform the functional test again. If the system still fails to detect the leak, please contact FFS Technical Support (1-800-984-6266).

Enabling/Disabling LinesAfter learning the line(s), each line will need to be enabled to allow monitoring. The Line Status reflects the current status.

Enabling LinesAt the T5 Series FMS console (LCD or by the web page), navigate to the FMS Control screen. Press the Enable / Disable button to enable the line.

Only while the line is enabled will it continuously monitor and test pressure levels by activating the STP as necessary.

Disabling Line ChannelsAt the T5 Series FMS console (LCD or by the web page), navigate to the FMS>Lines Control screen. Press the Enable / Disable button to disable the line.

Important: While the line is Disabled, FMS will neither maintain nor test line pressure levels.

If alarms or errors occur, please refer to the Alarms chapter of this guide.
