Veeder-Root Line Leak Application Guide <br /> Special Installations <br /> Manifolded Line Applications <br /> PLLD,WPLLD, and VLLD leak detection systems can handle product lines supplied by multiple tanks and pumps,to a maxi- <br /> mum of 8 tanks and pumps per product line. <br /> Standard line leak sensing and check valve equipment should be installed at the primary pump. <br /> To perform 0.2 and 0.1 gph tests,a non-vented SwiftCheck valve(P/N 330020-416)or FE Petro 65 psi Relief Check Valve(FE <br /> PM 402459931)should be installed on each of the other pumps supporting the manifolded product line.The Non-Vented Swift- <br /> Check Valve is rated to a maximum 70 gpm. <br /> A relay on a Four-Relay module or 1/0 Combination module must be available to control each secondary pump.The standard <br /> line leak modules will provide pump control output for the primary pump and the"Pump In"signal for the set. <br /> A typical manifolded line installation for PLLD is shown below: <br /> To Dispensers <br /> Flexible Pipe with Swivel or Union r <br /> Flexible Pipe with <br /> Ball Valve Ball Valve Swivel or Union <br /> SwiftCheck <br /> Valve <br /> PLLD Sensor <br /> Warning Tag Non-Vented <br /> SwiftCheck <br /> Valve <br /> O � <br /> pllSmitltanks.eps <br /> Master Pump Slave Pump <br /> Lower Numbered Tank Higher Numbered Tank <br /> Transducer Installation - Red Jacket CPT and Quantum CPT Pumps <br /> This installation procedure is to be used with Red Jacket CPT and Quantum CPT Pumps. <br /> 1. Install the Red Jacket CPT Transducer Adapter Kit(Red Jacket part number 144-326-5)following the instructions with the <br /> kit.Thread the PLLD transducer in the mechanical LLD port of the pump. <br /> IMPORTANT!Seal any pipe threads using a UL-classified, nontoxic pipe sealant suitable for the fuel involved.The figure <br /> below illustrates two PLLD transducer installations in Red Jacket CPT pumps-consult"PLLD and WPLLD Check Valves" <br /> on page 5,to determine what check valve you will need to install to perform your intended level of testing. <br /> 2. Verify that the console has Version x19 or later software. <br /> 3. Verify that the CPT Controller has Version 1.02 or later software installed. <br /> 4. Locate red switch bank labeled S1 on the CPT's Controller CPU board,and verity that dip switch 2 is set to the Closed <br /> position (to enable the PLLD precision line leak function),and dip switch 8 is set to the Open position(to disable the CPT's <br /> line leak function). <br /> 11 <br />
