It eliminates the need to break <br /> product lines for installation and service. <br /> l. Thread the PLLD transducer directly into the mechanical LLD port on the pump as shown in Figure 4-8. <br /> IMPORTANT! Seal any pipe threads using a UL-classified,nontoxic pipe sealant suitable for the fuel involved. <br /> 2. Feed the PLLD transducer cable through the watertight cord grip on the PLLD transducer junction box.Tighten the <br /> nut on the cord grip to ensure a watertight seal. <br /> 3. If necessary,install the FE Petro Model R precision check valve. <br /> i <br /> Pressure Test Port-remove plug to access valve clamp <br /> adjustment screw.Turn screw CCW until valve clamp is <br /> l <br /> all the way up and snug against manifold cover. <br /> Manifold cover <br /> Valve clamp(should be FE Petro O-ring <br /> snug up against cover) Part No.400211238 or 400333238 <br /> I <br /> PLLD transducer <br /> Check valve spring <br /> _ I <br /> P edCesion —-- ® I <br /> I <br /> check valve d o <br /> \ ; <br /> pumpsVep�.eps 1 / <br /> Figure 4-8. Location of PLLD Transducer and Model R Precision Check Valve in FE Petro Pump <br /> PLLD OPERATION WITH AN FE PETRO VARIABLE SPEED PUMP SYSTEM <br /> The FE Petro Variable Speed Pump System contains a submersible pump and adjustable frequency drive.For satisfactory <br /> operation with the PLLD System,you need to change the following in the adjustable frequency drive as described below: <br /> • Dip switch (SW2)settings <br /> • Rotary switch positions <br /> IMPORTANT!The correct hardware and switch settings must be used for the system to detect leaks less than 3.0 gph.If <br /> the correct hardware and switch settings are not used,the system will always pass 0.1 gph tests,but the results will be <br /> invalid. <br /> 1ST VFC Software Version 1.1 and 1.2 <br /> The settings and positions depend on the software version of the FE Petro IST-VFC(Intelligent Submersible Turbine- <br /> Variable Speed Controller).To determine the software version of the IST-VFC,remove its cover and check the label on <br /> the FE Petro chip,which is on the printed circuit board.The instructions below are for Version LI and 1.2 of the IST- <br /> VFC. <br /> 4-7 <br />
