Related Manuals 577013-465 Line Leak Application Guide 576013-879 TLS-3XX Series Site Prep and Installation Manual 576013-498 Pressurized Line Leak Interface Module - Installation Manual 576013-499 Pressurized Line Leak Controller Module - Installation Manual 577013-727 PLLD Alarm Quick Help Guide Safety Symbols The following safety symbols may be used throughout this manual to alert you to important safety hazards and precautions. Explosive Fuels and their vapors are extremely explosive if ignited. Flammable Fuels and their vapors are extremely flammable. Electricity High voltage exists in, and is supplied to, the device. A potential shock hazard exists. No Smoking Sparks and embers from burning cigarettes or pipes can ignite fuels and their vapors. OFF Turn Power Off Live power to a device creates a potential shock hazard. Turn Off power to the device and associated accessories when servicing the unit. No Open Flames Open flames from matches, lighters, welding torches, etc. can ignite fuels and their vapors. 1-1

Before You Begin No Power Tools Sparks from power tools (such as drills) can ignite fuels and their vapors. No People in the Area Unauthorized people in the area during service can create a potential for personal injury to you and them. Wear Eye Protection Fuel spray from residual pressure in the lines can cause serious eye injuries. Always wear eye protection. No Vehicles Moving vehicles in the area during service can create a potential for personal injury to you or others. Sparks from starting vehicles can ignite fuels and their vapors. Use Safety Barricades Unauthorized people or vehicles in the work area are dangerous. Always use safety cones or barricades, safety tape, and your vehicle to block the work area. Injury Careless or improper handling of materials can result in bodily injury. Gloves Wear gloves to protect hands from irritation or injury. Read All Related Manuals Knowledge of all related procedures before you begin work is important. Read and understand all manuals thoroughly. If you do not understand a procedure, ask someone who does. Before You Begin 1. Your console must have the PLLD Controller and PLLD Interface Modules installed. If these modules are not installed, the system will not be able to control the pumps or receive data from the PLLD transducers. If you need to install these modules, refer to manuals and. Also make sure that your console has additional slots to accommodate these modules. (If sufficient slots are not available, you will need an Module Expansion Board, part no. 847490-001.) 2. PLLD can only be installed in systems using approved pumps and piping types. Refer to the Line Leak Application Guide (part no. 577013-465) for updates on approved pumps, piping lengths, and piping types which are supported. 3. Ensure that the submersible pump is properly grounded as per the manufacturer s instructions. 4. We recommend that your system have a shutoff valve installed between the PLLD transducer and the product pipeline. Although not required for the PLLD system to work, the valve can aid in troubleshooting the system and in reducing any product spillage while performing service work in the submerged pump sump. 5. To make installation easier for sites having FE Petro Pumps or Red Jacket Pumps with no valve, you can use a socket made by K. D. Tools (part no. 2431) to install the PLLD transducer. System Description The PLLD System performs 3.0 gph leak tests following each dispense. Depending on the software enhancement module installed, the PLLD System will also allow, with certain pump types, 0.2 and/or 0.1 gph line tests at full pump pressure. Since PLLD executes these tests automatically, there is no need for separate annual line leak testing. Table 1-1 shows required modules, kits, and check valves for PLLD operation, by pump type. Table 1-2 and Table 1-3 list the contents of the two PLLD system kits and Table 1-4 lists the contents of the Non-Vented Valve kit. 1-2

2 Preparing the Site As you prepare the site, you need to consider: Manholes Stage II Vapor Recovery system Piping runs Manifolded product lines Manholes When using a SwiftCheck Valve, the manhole must provide at least 8 inches of clearance above the pump head to install the PLLD components. Stage II Vapor Recovery If there is a Stage II Vapor Recovery system installed that includes a device in the pressurized piping, such as a Healy Mini-Jet, see PLLD Installation with Stage II Vapor Recovery Systems on page 4-12 for installation guidelines. 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 PLLD system) can prevent the PLLD system from detecting line leaks in the area of pipeline downstream from the check valve. Manifolded Product Lines If the PLLD system will be used on manifolded product lines, see Manifolded Product Line PLLD Installation on page 4-9 for installation instructions. Submersible Pumps The PLLD system is not qualified for use with Red Jacket X5 model submersible pumps or FE Petro 550-3-S and 550-5- S model pumps. Pump output pressure must be 23 psi minimum. 2-1

5 Connecting PLLD System Wiring Safety Warnings Circuitry within the PLLD transducer and console barrier form an intrinsically safe, energy-limited system. This system makes the transducer intrinsically safe for use in a Class I, Group D hazardous location. The transducer wiring is intrinsically safe only when connected to Series Consoles. WARNING OFF This equipment uses lethal voltages and attaches to accessory components which operate in areas where flammable liquids and vapors may be present. Serious injury or death from shock, explosion, or fire may result if power is on during installation and the device is improperly installed. When installing this product: 1. Read and understand all instructions. 2. Turn off, tag, and lockout power to the console, dispensers, and submersible pumps while installing the PLLD system. 3. Use only supplied service parts to avoid compromising safety. 4. Do not allow PLLD pump control wires to share conduit with wires from intrinsically safe devices such as probes and sensors. 5. Insure that any assembled conduit only enters the console through the properly designated knockouts. 6. Wiring must comply with all applicable requirements of the National Electrical Code; federal, state, and local codes; and any other safety codes. 7. To protect yourself and others from being struck by vehicles, block off your work area during installation or service. Refer to the following wiring diagrams as you connect the wiring: PLLD system--figure 3-2 on page 3-4 Manifolded PLLD system--figure 5-7 on page 5-7 or Figure 5-8 on page 5-8 Red Jacket pumps-- Figure 5-2 on page 5-4 through Figure 5-5 on page 5-5 Non-Red Jacket pumps--figure 5-6 on page 5-6 Gilbarco Dispenser Isolation Box--Figure 5-9 on page 5-9 Manifolded product lines - dual FE Petro IST-VFC Controllers--Figure 5-10 on page 5-10 Manifolded product lines - dual Red Jacket IQ Controllers--Figure 5-11 on page 5-11 General Wiring Practices Be sure all wires are color-coded or carefully marked to identify their source. The PLLD Interface Module in the console comes with a connector in place. Do not remove the connector from the module or remove the module from its slot in the console during wiring. Terminal identifications appear only on the module bracket. Removing the connector from the module increases the risk of wiring errors. Label all connectors, using the supplied self-adhesive labels, according to the slot in which the modules are installed. 5-1

PLLD Interface Module Wiring Connections IMPORTANT! Once a connector has been wired on 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 (i.e., Line #1 (regular), Line #2 (super), etc.) of each PLLD wired to a module on the circuit directory inside the console door. PLLD Interface Module Wiring Connections OFF 1. Turn Off, tag, and lock out all AC power to the console and submersible pumps. 2. Connect the color-coded or marked wires from each PLLD transducer to the proper terminals on the PLLD Interface Module connector starting with position 1 [Figure 3-1 on page 3-3]. Wire each position on the module(s) in order without skipping a position, e.g., 1, 2, 3, 4, etc., not 1,3,4. IMPORTANT! The console software will identify PLLD Controller Module positions 1-3 (one module) and 4-6 (optional second module, highest in I.S. bay) with PLLD Interface Module positions 1-6. Therefore you must wire the PLLD System so that the STP connected to position 1on the PLLD Controller Module has the PLLD transducer installed that is connected to the position 1 on the PLLD Interface Module. The same relationship holds for the remaining 5 positions. 3. Connect the bare wire (shield) to one of the ground screws in the console only. 4. Maintain correct circuit orientation between the color-coded or marked field wires and connector terminals during wiring. PLLD Transducer Field Wiring Connections OFF 1. Turn Off, tag and lock out all AC power to the console and STP. 2. Using wire nuts, connect the white and black wires from the PLLD transducer to field wires in the junction box. Be sure to maintain correct circuit orientation between the color-coded or marked field wires and PLLD transducer wires during wiring. Cut off the transducer shielded ground wire (if present) flush with the cable jacket. Do the same for the cable shield. IMPORTANT! Connect the shielded cable to the shielded ground wire lug (supplied) in the intrinsically safe area of the console [Figure 3-2 on page 3-4]; do not connect it to the transducer. 3. Seal wire nut connections using the epoxy sealant furnished with each PLLD. Use one packet for no more than two wire nut connections. Ensure the end of the cable jacket is covered by the epoxy. Refer to Figure 5-1 as you prepare epoxy and seal connections. 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. 5-2

PLLD Controller Module Wiring A B C From probe, sensor, or transducer To console Make sure that the ends of cable sheathing are submerged in sealant Tie wrap Wire nuts Instructions: NOTE: When temperature is below 50 F (10 C), keep resin in a warm place prior to mixing (e.g., in an inside pocket next to body). 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. probes\epxy2w.eps Figure 5-1. Epoxy Sealant Connections IMPORTANT! 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. PLLD Controller Module Wiring PLLD pump control wiring varies depending on the pump manufacturer s relay control box. Refer to the appropriate wiring diagram (circuit diagrams are for switched hot dispensers): Red Jacket--Figure 5-2 on page 5-4 through Figure 5-5 on page 5-5 Non-Red Jacket--Figure 5-6 on page 5-6 Manifolded--Figure 5-7 on page 5-7 or Figure 5-8 on page 5-8 Gilbarco Dispenser Isolation Box--Figure 5-9 on page 5-9 IMPORTANT! Dispensers and console must be wired to the same leg of incoming power at the main electrical panel; otherwise damage may result to both. 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. IMPORTANT! 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 switch On the pump. To ensure that the pumps are unable to be activated in an emergency situation, it is best to have the Emergency Stop switch interrupt pump power at the circuit breaker panel via shunt breakers. Note: (OPTIONAL) In order to prevent 3.0 gph tests from running when STP power is switched Off, an Interlock relay may be used on the PUMP IN signal (ref. Figure 5-3 and Figure 5-7). 5-3
