Introduction

NOTICE

This manual contains instructions for installing the components for Veeder-Root Digital Pressurized Line Leak Detection (DPLLD). The DPLLD equipment performs 3.0 gph line leak tests following each dispense. Depending on the software enhancement module installed, the DPLLD equipment will also allow, with certain pump types, 0.2 and/or 0.1 gph line tests at full pump pressure. The DPLLD equipment executes leak tests automatically to eliminate the need for separate annual line leak testing.

1. The DPLLD, Digital Pressure Line Leak Detector, Form Number 8590, is Intrinsically Safe when installed according to Control Drawing Number 331940-008.

2. The TLS-450PLUS/TLS-450 console/DPLLD sensors are not supported by the Red Jacket Variable Speed Flow Controller (VSFC). The VSFC is designed for use with PLLD sensors/TLS-350 consoles only!

3. The SwiftCheck valve requires a 3” hex socket (or wrench) for tightening it in the pump’s leak detector port. The non-vented SwiftCheck valve requires a 1-1/2” hex socket (or wrench) for tightening it in the pump’s leak detector port.

Warning Tags

Turn off, tag (using the warning tags provided), and lockout power to the console and submersible pumps while installing the DPLLD equipment. This will prevent either a dispense attempt or the DPLLD equipment from automatically starting up the pump.

Warning tags [Figure 1] are provided with the DPLLD equipment. For your safety and the safety of others who may service dispensers, submersible pumps, or DPLLD equipment, you must attach a tag to each of the following devices where it can clearly be seen by a service person performing work on the system:

•Console

• Submersible pump

• Dispenser filter

Figure 1. Warning tag

Site Considerations

Manholes

When using a SwiftCheck Valve, the manhole must provide at least 8 inches of clearance above the pump head to install the DPLLD components.

Unused Piping Runs

Where piping runs have been installed for future use, but are connected to the active piping system, isolate the inactive lines from the active lines using a shutoff valve. Failure to do so may harm system performance.

Existing Check Valves

You must ensure that there are no existing check valves already installed in the pipeline. The presence of any check valve (other than the one used with the DPLLD equipment) can prevent the DPLLD equipment from detecting line leaks in the area of pipeline downstream from the check valve.

Manifolded Product Lines

Follow these guidelines as you install a DPLLD equipment into multiple manifolded tanks:

• Dielectric unions and flexible piping elements should be used as required by federal, state, and local

requirements for the specific piping application. Location of unions may vary with configuration.

• An I/O Module in the console is required to control the pump on the higher-numbered tank and pump control

output for the primary tank, and the “Pump In” (Dispenser ON) signal for the set.

• A DPLLD transducer is only required in the master pump.

• Remove any other check valve or leak detect device in the line that is not shown.

• Refer to the Line Leak Application Guide for check valve requirements.

• The Red Jacket (page 14)

• Red Jacket Maxxum Big-Flo (page 15)

• FE-Petro (page 16)

Red Jacket Standard and Quantum Pumps (DPLLD w/SwiftCheck)

Use this installation procedure to install a DPLLD transducer with a SwiftCheck valve in a Red Jacket Standard or Quantum pump.

Disconnect, lock out, and tag all AC power to the TLS console, dispensers and submersible pumps.

When servicing equipment, use non-sparking tools and use caution when removing or installing equipment to avoid generating a spark.

1. If a ball valve is installed down line from the pump, close it.

2. Do one of the following:

a. If the submersible turbine pump is equipped with a mechanical LLD, remove the mechanical unit and any

related tubing and fittings, or

b. If the submersible turbine pump is not equipped with a mechanical LLD, remove the 2-inch mechanical

LLD port plug.

3. Ensure that the sealing surface for the SwiftCheck valve’s external o-ring is smooth and free from corrosion, pitting, and any material build-up [Figure 3].

Failure to ensure a smooth seal surface can result in false line leak alarms.

5. If there is a Stage II vapor recovery device installed, go to Step 7. If there is no Stage II vapor recovery, install the SwiftCheck valve [Figure 4] in the mechanical LLD pump port. Thread the DPLLD transducer into the SwiftCheck Valve.

WARNING

Do not overtighten the SwiftCheck valve when installing it into the pump. Over tightening the valve can cause a flow restriction in the line!

WARNING

Seal the NPT threads only with a UL-Classified, nontoxic pipe sealant suitable for the fuel involved (for high-alcohol fuel blend applications, Loctite 564 is recommended). Apply sealant in a manner that prevents it from entering and contaminating hydraulic cavities.

9

DPLLD Transducer Installation Red Jacket Standard and Quantum Pumps (DPLLD w/SwiftCheck)

6. If there is a Stage II vapor recovery device installed in the pressurized piping you must install the SwiftCheck valve into a Red Jacket leak detector fitting (P/N 038-072) as shown in Figure 5 instead of in the pump’s leak detector port. Because the DPLLD transducer must be installed downstream from these devices, a monitored containment sump is required.

WARNING

There must not be a check valve installed between the SwiftCheck valve and the pump for DPLLD to function properly.

Ensure that the Healy pump is wired according to the manufacturer’s instructions and utilizes isolation relays.

Lubricate the external o-ring on the SwiftCheck valve using mineral oil or other suitable lubricant and thread the valve into the Red Jacket fitting.

DPLLD Transducer Installation FE Petro Pumps

NOTICE

You will also need to install a reducing tee (customer supplied) in the 3-inch discharge port of the pump with the 2inch opening facing up. Thread the PLLD transducer into the 2-inch opening of the tee.

WARNING

Seal the NPT threads only with a UL-Classified, nontoxic pipe sealant suitable for the fuel involved (for high-alcohol fuel blend applications, Loctite 564 is recommended). Apply sealant in a manner that prevents it from entering and contaminating hydraulic cavities.

FE PETRO VARIABLE SPEED PUMP SYSTEM MODIFICATIONS

The FE Petro variable speed pump system contains a submersible pump and adjustable frequency drive. For satisfactory operation with the DPLLD System, you need to change the following in the adjustable frequency drive as described below:

• Dip switch (SW2) settings

• Rotary switch positions

WARNING

IST-VFC Software Versions 1.1 and 1.2

The settings and positions depend on the software version of the FE Petro IST-VFC (Intelligent Submersible Turbine-Variable Speed Controller). To determine the software version of the IST-VFC, remove its cover and check the label on the FE Petro chip, which is on the printed circuit board. The instructions below are for Version 1.1 and

1.2 of the IST-VFC.

Dip Switch SW2

Pole 1 on dip switch SW2 (Figure 13) controls the pump start up time. Set this switch to OFF so that the submersible pump will run at 34 psi for 6 seconds each time it is started. Pole 2 does not affect DPLLD operation; it sets the product type for the IST-VFC (ref. Table 1). .

The correct hardware and switch settings must be used for the system to detect leaks less than 3.0 gph. If the correct hardware and switch settings are not used, the system will always pass 0.1 gph tests, but the passing results will be invalid.

Table 1. FE-IST-VFC Product Type Dip Switch (SW2) Settings

Pole 1 Pole 2

OFF (required) ON-gasoline, OFF-diesel

Rotary Switch

The rotary switch (Figure 13) controls the pump pressure of the submersible pump. As shown in Table 2, use positions 1, 2, 3, or 4 to run the pump at a pressure range compatible with DPLLD operation.

Do not use positions 0, 5, 6, 7, 8, or 9 with versions 1.1 or 1.2 software.

WARNING

Refer to the appropriate Site Prep manual (P/N 577014-073 - TLS-450PLUS or P/N 577013879 TLS-450) for required wiring types/lengths for pressure transducer and pump control field wiring.

DPLLD Transducers

1. Pull a shielded, 2-conductor cable from each DPLLD transducer’s sump junction box to the appropriate USM module in the TLS console. NOTE: The transducer is an intrinsically safe device and its wiring must not share a conduit with any non-intrinsically safe device.

Disconnect, lock out, and tag all AC power to the TLS console, dispensers and submersible pumps.

2. Using wire nuts, connect the white and black wires from the DPLLD transducer to field wires in the weatherproof sump junction box (ref. Figure 14). Be sure to maintain correct polarity between the color-

coded or marked field wires and DPLLD transducer wires when making all connections. Cut off the transducer shielded ground wire (if present) flush with the cable jacket. Do the same for the cable shield.

The shielded cable drain wire must be connected to the ground lug in the intrinsically safe area of the console, not to the transducer!

Figure 14. Field Connections Of DPLLD Transducer

3. Seal wire nut connections using the epoxy sealant furnished with each transducer. Use one packet for no more than two wire nut connections. Ensure the end of the cable jacket is submerged in the epoxy. Refer to Figure 15 as you prepare epoxy and seal connections.

Do not put more than two wire nut connections in one epoxy sealant bag or the connections will not be properly sealed. Improper sealing of the connections will result in inaccurate system readings and possibly false alarms.

1. Open epoxy sealant package, and remove resin pak.

2. Holding resin pak as shown in A, bend pak along long length.

3. As shown in B, firmly squeeze the RED SIDE of the resin, forcing it through the center seal and into BLACK SIDE.

4. Mix thoroughly to a uniform color by squeezing contents back and forth 25-30 times.

5. Squeeze mixed, warm resin into one end of bag and cutoff other end.

6. Slowly insert wiring connections into sealing pack until they fit snugly against the opposite end as shown in C.

7. Twist open end of bag and use tie wrap to close it off and position the tie wrapped end up until the resin jells.

CAUTION: Epoxy sealant is irritating to eyes, respiratory system, and skin. Can cause allergic skin reaction. Contains: epoxy resin and Cycloaliphatic epoxycarboxylate.

Precautions: Wear suitable protective clothing, gloves, eye, and face protection. Use only in well ventilated areas. Wash thoroughly before eating, drinking, or smoking.

DPLLD Transducer Wiring Connections

• Be sure all wires are color-coded or carefully marked to identify their source and to maintain polarity.

Once a connector has been wired to a module and the console has been programmed, the connector and module cannot be moved to another slot without reprogramming the system.

• Record the location (e.g., Line #1 (regular), Line #2 (super), etc.) of each DPLLD transducer on the circuit directory inside the right-hand console door.

Disconnect, lock out, and tag all AC power to the TLS console, dispensers and submersible pumps.

1. Connect the two color-coded or marked wires from each DPLLD transducer to the USM module. (see

Figure 16). Maintain correct polarity between the color-coded or marked field wires and the connector terminals during wiring.

2. Connect the transducer cable’s bare wire (shield) to one of the ground lugs in the TLS console.

Pump Wiring Connections

The console must be able to detect when dispensers are switched On or Off so it only initiates line leak tests when the dispenser is switched Off. The console must also be able to start the submersible pump to perform a line leak test, and shut off the pump if a leak is detected.

Figure 16. DPLLD Transducer Wiring To USM Module

Dispensers and TLS console must be wired to the same leg of incoming power at the main electrical panel; otherwise damage to both may result.

The console, when wired correctly, will control the pump independent of the dispenser control circuits. It is imperative that when the emergency stop switch is wired and tested, the console’s pump control circuitry CANNOT start up the pump. To ensure that the pumps are unable to be activated in an emergency situation, have the emergency stop switch interrupt pump power at the circuit breaker panel via shunt breakers.

1. Referring to the appropriate wiring diagrams below, pull the necessary number of #14 AWG color-coded or

marked copper wires from STP control boxes, self-serve system/dispenser, and power panel to the appropriate I/O module of the TLS console. Since wiring for multiple pump controls may be entering the console through the same conduit opening,

color code or mark each wire to identify its source!

The dispensers and TLS console must be wired to the same leg of incoming power at the main electrical panel; otherwise damage may result to dispensers and console.

2. DPLLD pump control wiring varies depending on the pump manufacturer’s relay control box. Refer to the

appropriate wiring diagram example below to connect DPLLD controlled pumps to the I/O Module in the TLS console (circuit diagrams are for switched ‘hot’ dispensers):

• Red Jacket (ref. Figure 17, Figure 18, and Figure 19)

• Non-Red Jacket (ref. Figure 20)

WARNING

Do not switch On power to the console. This must be done by an Authorized Service Contractor during the warranty checkout and start-up procedure! An Authorized Service Contractor must program the DPLLD set-up information into the console before beginning these DPLLD equipment checks.

Repeat the four steps below for each DPLLD monitored line.

1. VENT THE LINE

WARNING

Disconnect, lock out, and tag all AC power to the TLS console, dispensers and submersible pumps.Turn Off, lock out, tag power to the STP.

When servicing equipment, use non-sparking tools and use caution when removing or installing equipment to avoid generating a spark.

a. Vent the line to zero.

b. Reseal the line.

c. Turn On power to the STP.

If the pump has a functional element or PressurStat, verify that it is not leaking!

2. RED JACKET STANDARD, QUANTUM, AND MAXXUM PUMPS WITH DPLLD TRANSDUCER

AND PRESSURSTAT ONLY

You MUST reset the Pressurstat’s relief pressure as part of the DPLLD installation.

a. Unscrew the protective brass cap from the adjustment screw (Figure 25).

b. When the adjustment screw is fully down, the relief pressure is approximately 40 psi.

c. Install a pressure gauge in the line.

d. Set the relief pressure to 20 - 25 psi (verify the relief pressure by using the console - [refer to “5. Enable

the Line for Dispensing” on page 32 for the procedure to obtain pressure readings]).

e. Check the sealing surface for the cap’s o-ring and the condition of the o-ring. Clean or replace as required.

f. Replace the brass cap and hand tighten (the o-ring completes the seal between the body and cap).

3. DETERMINE DPLLD TRANSDUCER PRESSURE OFFSET

New transducers are now factory sealed and their internal chamber cannot be equalized to atmospheric pressure by opening a vent screw as in the past. The Pressure Offset test procedure described in this step MUST be performed when using new DPLLD transducers with serial numbers of 100,000 or above, in sites located at altitudes above 2,000 feet. Note: this procedure can also be used with transducers having serial numbers below 100,000 instead of using the vent screw to equalize pressure.

Before this procedure is performed, the pressure in the line MUST be vented to zero. It is recommended that this procedure be performed after installing the transducer, before energizing the STP. Consult the TLS-450 console’s online help to perform the following steps:

• Run Pressure Offset Test

• Enter the Pressure Offset Value for the DPLLD Transducer

4. PURGE AIR FROM THE LINE

Follow accepted procedures, or appropriate pump manual, to purge all air from the product line being enabled for dispensing.

5. ENABLE THE LINE FOR DISPENSING

After completing the DPLLD installation, the console will not enable dispensing from a line until a 3.0 gph test on the line has been passed. In this step, as you run the required 3.0 gph test, you will also verify that the Pump On and Pump Off pressures are within their proper operating ranges.
