Warning

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 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. 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.

TS-SCCM contains aluminum, care must be taken to avoid ignition due to impact.

Overview

The TS-SCM (Secondary Containment Monitoring) system is a continuous secondary containment monitoring system that  monitors the interstitial spaces of double walled tanks and sumps, secondarily contained product and vapor return piping. 

This product can be ordered as an available option with Franklin Fueling Systems’s TS-550 and TS-5000 FMS consoles.

The TS-SCM system is comprised of an application running on a T5 series FMS console and all necessary input and  output modules with installation kits. The Secondary Containment Control Module (SCCM) consists of a vacuum sensor,  solenoid valve, mechanical bypass valve, and vacuum manifold. SCM uses the STP siphon port vacuum to evacuate the  containment space and AutoLearn® technology to determine the characteristics of each secondary containment area that  is monitored. 

Warning

SCM equipment operates at a standard 2" to 6" Hg and should only be used to monitor containments that are designed to withstand these vacuum levels. Refer to the containment manufacturer for further information.

Note:  SCM should be tested annually after installation.

*Refer to manufacturers’ installation  guides or data sheets to calculate  containment area volumes.

**All containment areas MUST be  compatible with the vacuum levels  listed.

The term containment (in secondary containment) refers to the interstitial spaces of double walled piping, sumps and  tanks that serve as a secondary containment if the primary containment is damaged.

Individual containment sections of a given product pipeline may be jumpered together via a vacuum line to form one larger  single containment. An example of ‘jumpered’ containment spaces is the secondary containment layer of product piping  from the turbine containment to the first dispenser, and then jumpered to the secondary containment layer of the same  product piping on the other side leading to the next dispenser containment area.

Several containment areas may be grouped together and used with a single Secondary Containment Control Module (TS-

SCCM). No more than four (4) SCM groups should be used per pump siphon. The combination of any containment group  may not exceed the volume limits listed for SCM.

Note:  DO NOT jumper tank interstitials with other tank interstitials or other containments.

Note:  DO NOT jumper containment areas of unlike product pipelines together.

Note:  If grouping multiple containment areas together, the installer will need to purchase and use the vacuum hose,  fittings, and clamps to secure the connection as specified by FFS.

Note:  Both intrinsically safe and explosion proof conduits need to be available inside of the turbine containment for the 

TS-SCCM.

Installation

Before starting installation, conduct a site survey to identify potential containment groups. Based on that survey, plan out  which STP sump the equipment will be installed in and how containment areas will be grouped together.

Warning

Lockout and tag circuit breakers, and disconnect console power wiring before installing or servicing any system wiring.

Warning

Warning

DO NOT make solenoid and/or sensor wiring connections with live power connected to the console or any module.

TS-SCCM contains aluminum, care must be taken to avoid ignition due to impact.

Caution

Do not run intrinsically safe (IS) wiring and non-intrinsically safe (non-IS) wiring in the same conduit.

Note:  TS-SCCM must be installed in accordance with the national electrical code, ANSI/NFPA 70, CEC or other  applicable national or local codes.

Note:  Maximum torque on supplied hose clamps is 20 inch-lbs.

1.  Pull all wiring through the conduits that will be used for the TS-SCCM vacuum sensor and solenoid valve. The  intrinsically safe (IS) sensor wiring must be run in an IS conduit. The non-IS solenoid wiring must be run in an  approved explosion proof rigid metal conduit.

2.  Mount the TS-SCCM inside of the turbine  containment area, supported by rigid,  explosion proof conduit. Then orientate the  units to allow enough clearance to make the  vacuum line connections without stretching,  kinking, or creating sharp bends in vacuum  hoses. The SCCM cover is installed with the  label upwards. See Figure 3.

3.  Connect the solenoid wiring to the field wiring  using wire nuts to secure the connections.

6.  Plumb the siphon hose from the VAC port of the TS-SCCM to the siphon check valve. Secure the hose to the fittings  using one of the supplied hose clamps at each end.

7.  Plumb the containment vacuum hose from the INT port of the TS-SCCM to the containment area to be monitored. 

Secure the hose to the fitting using one of the supplied hose clamps per fitting. Install T-fittings and clamps where  necessary to connect the hoses if more than one containment area will be monitored as a group.

Note:  The containment vacuum hose must be placed in the lowest point of the containment space. For double walled  tanks, this means ensuring that the vacuum line rests at the bottom most part of the tanks interstitial space. Use  the same industry procedures used to install any sensor at the bottom of a double walled tank.

8.  Secure all containment boots, lids and caps. Clean pipe surfaces to clear debris or foreign objects prior to tightening  secondary test boots on secondary containment product or vapor return piping. Make all jumper connections inside of  dispenser sumps by using supplied hardware.

9.  Inside the console, the TS-SCCM solenoid wiring must enter the console from the explosion proof rigid conduit through  a designated knockout on the non-IS side of the barrier inside. Connect the line, neutral, and ground wire of the  solenoid to a single unused channel on the Relay Module (RLY). The solenoid should be wired to the Common (C) and 

Normally Open (NO) contacts of the channel selected. Source voltage (110 VAC) will need to be provided to the dry  contact relay.

Turbine Pump Interface (TPI) Applications (Alternate STP Control)

TPI is an alternative to using the Relay Module to actuate an STP on demand (from a dispenser request or SCM). Just  as with using a relay channel, this method will provide positive pump shutdown on alarm (if that option is chosen in the  setup). When using the standard TPI feature of the console to control a STP, be sure to map the SCCM vacuum sensor  as an “Input” for the STP that it is connected to (as shown in the TPI table). This will allow the SCM application to actuate  the STP when it is necessary to regulate the vacuum levels in the containment. For further information and instructions on  programming TPI and/or Relay Modules to control a STP, please refer to the T5 FMS Programming Guide (p/n 000-2142).

Pre-Operational Containment Testing

Pre-operational containment tests determine the tightness of the entire SCM system, including TS-SCCM and interconnect tubing. These tests consist of two separate procedures: Containment Tightness Tests and STP Siphon Tests. The  first procedure, Containment Tightness Testing, will determine whether the containment areas chosen to be monitored are  tight. The second, STP Siphon Testing, will determine if the STP is capable of creating enough vacuum for proper SCCM  operation. 

The Containment Tightness Testing procedure assumes that all STP’s and pump controllers have been installed, wired,  calibrated, and are operational and in accordance with their respective installation and operation procedures. It also  assumes that all T5 FMS console programming has been completed. 

Warning

DO NOT apply vacuum or pressure until consulting the containment manufacturer on the maximum allowed vacuum or pressure levels.

Warning

DO NOT use equipment that is not explosion proof in classified areas. Keep vacuum pumps outside class 1, division 1, and class 2 areas. Refer to NFPA 30A, chapter 8.

Caution

DO NOT proceed to the Learn Process until each containment successfully completes pre-operational testing. Failure to perform these tests or ignoring any failed tests may prevent the

SCM application from detecting a containment fault.

Note:  State and/or local laws may require a separate, more stringent containment tightness test. ALWAYS verify and  comply with local regulations.

Note:  The STP connected to the SCCM 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.

3.  Install a vacuum gauge, regulator and isolation / shut-off ball valve in-line, onto the vacuum pump. With the ball valve  closed, power on the vacuum pump. Adjust the regulator to 6.5" – 7" Hg maximum. Power the vacuum pump off.

4.  Remove the plug in the leak generator port on the SCCM. Connect the vacuum pump to this port.

5.  Power the vacuum pump on. Open the isolation ball valve slowly to evacuate the containment area to 6" Hg. Close the  isolation ball valve:

• If the vacuum level does not increase after 30 seconds while the vacuum pump is running; large  containments may take up to 10 minutes. Inspect each component for leaks.

• If the gauge drops below 6" Hg immediately after closing the valve then steadies before zero. 

Slowly open the isolation ball valve again to evacuate the containment to 6" Hg. Repeat as  necessary until containment remains at 6" Hg and close the isolation ball valve. 

• If the gauge immediately drops to zero. This indicates that a leak exists. All leaks must be  identified and repaired before continuing this test.

Note:  Vacuum leaks can be identified by pressurizing the containment area per the manufacturer’s specified levels, then  spraying a solution of water and liquid soap on connections and fittings. Consistent bubbling on soaped connections/fittings will give a visual indication of the source of a leak. 

Consult the manufacturer’s documentation for

appropriate pressure levels.

6.  Once a stable vacuum level is reached (4.5" – 7" Hg on the vacuum gauge  in-line with the vacuum pump), record the level. Use the table to the right  to determine the required wait time. The containment vacuum level should  remain stable throughout the entire wait time; the vacuum pump may be shut  off at this point.

If the vacuum level drops more than 1" Hg during the required wait time, then  the containment failed the test. All leaks must be identified and repaired first,  then the Containment Tightness Test should be repeated until it successfully  completes.

7.  If a vacuum gauge has been installed at the end of the system, compare the gauge reading with the console. If the measurements are not within ±2" Hg, a blockage may exist within the  containment and/or between the SCCM and vacuum gauge. All blockages must be identified and corrected. Once the  blockage is corrected, restart the Containment Tightness Test.

8.  Uninstall the vacuum pump, regulator, isolation / shut-off valve and vacuum gauges at this time. Continue on to the 

STP Vacuum Test in the next section. Do not replace the Leak Generator Port Plug.

STP Siphon Flow Rate Test

Warning

Failure to open the leak generator (TS-SCMCAL) during this test can apply an excessive vacuum level to the containment, causing irreversible damage. Ensure that the leak generator is installed properly and that the toggle switch is in the OPEN position prior to energizing the STP.

Note:  During this procedure the containment reaches 9" Hg, which will cause the console to display a High Vacuum  alarm and disable the containment. If Pump Shutdown on Alarm is chosen in the options, a disabled containment  will not allow the STP to be activated. Navigate to the SCM Control screen, press  Reset Alarm to continue.

1.  Install a vacuum gauge and the vacuum leak generating device (TS-SCMCAL) into the leak generator (LG) port on the 

SCCM using necessary fittings. Switch the toggle valve to the UP (open) position.

2.  At the T5 series FMS console (using either the LCD or Tank Sentinel Anyware), navigate to the SCM Control Menu. 

Press the  Solenoid button — this activates (opens) the solenoid. 

3.  Activate the STP by lifting the appropriate dispenser handle. 

4.  With the STP on and the toggle valve open, the vacuum level must be able to reach at least 6.5" Hg. Verify vacuum  levels at the gauge connected to the containment area. 

Large Containments (>50 gal.) may take several minutes. For large containments, close the leak generator until the  vacuum level reaches approximately 6" Hg. Open the leak generator. Allow the vacuum to build. The vacuum level  must be able to reach at least 6.5" Hg, but, if the vacuum is not able to reach at least 6.5" Hg, then the STP siphon  assembly must be repaired or replaced.

5.  Once the vacuum level is verified above 6.5" Hg, return the hook signal to turn off the STP. 

6.  At the T5 series FMS console (LCD or TSA), navigate to the SCM Control Menu. Press the  Solenoid button — this  deactivates (closes) the solenoid.

7.  Allow the vacuum to decay to 0" Hg.

If you are proceeding to the Learn Process chapter next, the TS-SCMCAL may remain installed at the SCCM leak  generator port.

Learn Process

Each containment area must be Learned before the SCM system can continuously monitor it. Learning involves  evacuating the containment area, then introducing a calibrated leak using the Leak Generating Kit (TS-SCMCAL). The  system learns what the evacuation and decay curves look like by employing this process. The system then uses the  curves it’s learned to determine if there is a leak while it monitors the containment area. 

Note:  All console programming must be completed prior to the learn process. Refer to the SCM Setup (Console 

Programming) chapter in this manual for details. Administrator privileges are necessary to Learn containments. 

Refer to T5 FMS Programming Guide (p/n 000-2142) for information on gaining Administrator privileges.

Note: Complete the Pre-Operation Containment 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  Reset button. Always restart the Learn Process from the beginning.

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

When to Learn/Re-Learn

•  SCM installation and start-up

•  After repairs or modifications to containment areas

•  After repairs or modifications that may affect the siphon flow rate

•  After 4-20mA Input Module replacement

•  After certain 4-20mA Input Module firmware upgrades (consult FFS Technical Services Department)

•  If moving the SCCM to another 4-20mA channel

•  When adding or removing volume from a containment off (closed) on (open)

Figure 8 – Leak Generator Kit (TS-SCMCAL)

Procedure

1.  The SCCM leak generator port is plugged for normal operation but may have been removed for pre-operational testing. 

If the leak generator port is plugged, remove the plug.

2.  Install a TS-SCMCAL at the leak generator port on the SCCM; the TS-SCMCAL may remain installed from the Pre-

Operational Containment Testing chapter.

3.  Switch the toggle valve to the Up (closed) position.

4.  At the T5 series FMS console (LCD or TSA), navigate to the SCM Control screen. Verify that the console is indicating  less than 0.2" Hg before the containment is Learned. If the vacuum level is above 0.2" Hg, open the toggle valve to  equalize containment vacuum to 0" Hg. Close the toggle valve when the containment is below 0.2" Hg.

5.  Press/Click the  Learn button. SCM will activate the pump and open the solenoid valve. The vacuum level of the  containment should rise and the Learn Message should display Learning Evacuation Curve. When the vacuum  reaches 6" Hg, the solenoid will close and the STP will turn off. The solenoid may cycle on and off during evacuation,  which is part of its normal operation during this procedure.

6.  When the message Open Leak Toggle Valve appears, switch the toggle valve to the UP (open) position. SCM will learn  the vacuum decay curve and display Learning Decay Curve on-screen. The vacuum level will begin to fall.

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

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

8.  Once the containment has been successfully learned, enable the containment on the Containment Control screen with  the leak generator open. The console will automatically begin a test on the containment. This test should fail, forcing  the containment into alarm status. 

9.  Close the leak generator. To clear the alarm, navigate to the Containment Control screen and choose  Reset Alarm. If  the Auto-enable on Reset option is turned on in the SCM section of programming, the containment will be automatically  enabled after resetting the alarm condition and will automatically begin a test on the containment. This test should  pass, allowing SCM to continue to monitor the containment. If this test fails, isolate why the test failed, make necessary  repairs, and then retry the test.

10. Remove the leak generator and replace the leak generator plug. Apply TFP tape sealant to the threads of the plug,  then tighten the plug.

If alarms or errors occur, refer to the Alarms chapter of this guide. When the condition is  corrected, restart the Learn Process.

Description

The Learn Process was started with .5" Hg or more existing in the containment. The Learn Process  needs to be restarted at 0" Hg.

The containment has been Learned with no errors.

Displayed during the Learn Process to indicate that the calibrated leak decay curve is being recorded.

During the Learn Process, SCM is recording the time and vacuum levels while evacuating the  containment.

A vacuum leak is present when the leak generator should not be open.

Vacuum level is constant or has risen while Learning the decay curve.

The leak valve was opened when prompted, but the leak valve was closed before the Learn Process  was completed. Restart the Learn Process and open the leak valve when prompted. Close the leak  valve after the Learn Process has completed.

The containment has been programmed, but the containment has never been Learned. Refer to the 

SCM Learn Process section to Learn the containment. Follow all Warnings, Cautions, and Notes prior  to Learning the containment.

This is a required step during the Learn Process. When shown, open the leak generator.

SCM sent a request to start the STP, but the TPI or the relay module didn’t send confirmation that the 

STP was running. The STP may be used or disabled by other applications.

This message is displayed if the containment is enabled in the setup, not Learned, and the sensor  was disconnected. Verify sensor wiring.

Evacuation Learning exceeds the limit.

The leak valve is not open during the Learn Process. Restart the Learn Process and open the leak  valve when prompted to by the console.

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 at any time while troubleshooting a Warning or Alarm this guide is not able to help you correct the issue, please  contact FFS Technical Services.

Thermal Contraction

Liquid in Containment

Caused by temperature variations of the air (or liquid if present) in the containment.

This will decrease the containment size. If liquid is drawn through the containment, through  the STP siphon, various parameters and containment vacuum readings will be incorrect. 

Containments should remain free of liquid at all times.

Siphon Function Check The siphon must be able to pull a vacuum of 8" Hg or more if connected to other equipment. 

The vacuum also must have a minimum flow rate of 146 L/Hr. Perform a STP Siphon Flow 

Rate Test as illustrated in the Pre-Operational Containment Testing chapter.

SCCM Vacuum Sensor 

Function Check

The transducer is sending incorrect data or no data to the console. Verify wiring from the  transducer to the console. If wiring is correct, setup and program the transducer on a  different, unused channel for testing.

STP Function Check

Verify Programming

SCCM Vacuum Relief 

Valve Function Check

Use the dispenser to signal the STP when the dispenser is authorized then the STP should  run. Also, SCM must be able to signal the STP pump on. Force a test on the containment  using the SCM Control screen. The STP will start only if necessary to evacuate the  containment. If the STP does not run to evacuate the containment, verify programming.

Refer to the SCM Setup chapter of this guide for all SCM related programming information.

The mechanical vacuum relief valve is designed to open when containment vacuum levels  reach or exceed 10" Hg. If at any time the containment vacuum level exceeds 10" Hg while  the pump is on, this error will occur as an indication of a relief valve failure.

Clearing Alarms

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

Administrator privileges will be necessary to clear SCM alarms on the T5 FMS console. For instructions on how to obtain  an Administrator access level, please refer to the T5 FMS Programming Guide (p/n 000-2142).

1.  Identify the alarm on the SCM 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 SCM Control screen.

5.  Select  Reset Alarms on the Control screen. 

6.  If Auto-Enable on Reset is chosen in the SCM Setup, then the containment will enable automatically. Otherwise, select 

Enable/Disable on the Control screen.

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

Enabling/Disabling SCM

After learning the channel(s), each channel will need to be enabled to allow containments to be monitored. The 

Containment Status reflects the current status of the channel.

Enabling SCM Channels

At the T5 FMS console (LCD or TSA), navigate to the SCM Control screen. Press the  Enable/Disable button to enable  the channel.

Only while the channel is enabled will that channel continuously monitor and test vacuum levels by activating the STP  as necessary. Normal SCM operating vacuum level is between 2" Hg and 5" Hg. During vacuum recharge periods, it is  normal for the vacuum levels to reach 6" Hg.

Note:  A channel will not enable properly if it is not learned, in an alarm status, or if an error condition exists (such as a  sensor malfunction). An alarm must be reset to enable a SCM channel.

Disabling SCM Channels

At the T5 FMS console (LCD or TSA), navigate to the SCM Control screen. Press the  Enable/Disable button to disable  the channel.

Important: While the channel is Disabled, SCM will neither maintain nor test containment vacuum levels.

Disabling the channel will force the console to display a Containment Not Enabled warning. This warning will also appear  on the SCM History Report. The channel may be re-Enabled  at any time.

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

SCM Annual Functional Testing

Perform a SCM Functional Test annually. This test will verify that the SCM 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 FMS console (via LCD or TSA), navigate to the SCM Control  screen. Press the  Enable/Disable button to disable the channel.

2.  Remove the plug in the Leak Generator (LG) port on the SCCM. Connect the TS-SCMCAL (Leak Generator Kit) to this  port.

3.  Switch the toggle valve to the DN (closed) position.

4.  Enable the channel. Wait for the containment vacuum levels to reach normal operating levels.

5.  Switch the toggle valve to the UP (open) position. 

6.  The vacuum levels will then fall, which could take several minutes for large containments. Verify that the console  displays an alarm. 

7.  The channel will be disabled by the SCM application. Remove the TS-SCMCAL. Apply TFP tape sealant to the threads  of the Leak Generator Port Plug. Replace and tighten the plug.

8.  At the T5 FMS console (via LCD or TSA), navigate to the SCM Control screen. Press the  Reset Alarm button to  enable the channel, then press the  Enable/Disable button to enable the channel. Resume normal operation.

9.  If the SCM Annual Functional Test passed, 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 annual test again. If the channel still fails to detect  the leak, please contact FFS Technical Support.
