VSFC Site Installation Examples <br />Emu <br />Installing a Pressure Transducer in a STP <br />14. Return to the PLLD Site Prep and Installation manual (P/N 576013-902) and complete the PLLD System <br />Checkout procedure (PLLD System Checkout section). <br />Installing a Pressure Transducer in a STP <br />For installations in which the Pressure Transducer and pump control wiring have separate conduits to the VSFC <br />unit, follow the procedure below to install the Pressure Transducer in the STP: <br />1. Reference Figure 7 and Figure 9 for installation examplesl. <br />2. Install Pressure Transducer (P/N 848480-001) as instructed in PLLD Transducer Installation Manual (P/N <br />576013-902) for the appropriate STP. <br />3. In the weatherproof junction box, connect the Pressure Transducer cable to the cable from the VSFC Master <br />Unit using wire nuts as shown in Figure 19 and epoxy seal connections as shown in Figure 18. <br />— ® Black <br />To From <br />VSFC <br />Master Seal -off Pressure <br />� i <br />Unit -h ® White Transducer <br />Rigid conduit I <br />Epoxy sealed connections in a <br />mdjacket/vsfc2o.eps weatherproof junction box <br />Figure 19.

Place the epoxy pack with the encapsulated wiring connections in the sump's weatherproof junction box. <br />Replace and tighten the junction box cover. <br />5. Connect the two wires from the Pressure Transducer to the VSFC Master Unit as shown in Figure 10 or <br />Figure 12 as applicable. <br />6. Return to the PLLD Site Prep and Installation manual (P/N 576013-902) and complete the PLLD System <br />Checkout procedure (PLLD System Checkout section). <br />Flow Calibration Test <br />After performing the PLLD System Checkout procedure, calibrate the VSFC flow rate as follows: <br />1. With the nozzle closest to the pump fully open and dispensing into an approved 5 gallon container or gas tank <br />of a vehicle, record the gallons pumped for a timed interval of 15 seconds. For best accuracy, wait 15 <br />seconds after lifting the dispenser handle before beginning the timed interval. <br />2. Calculate the flow rate (gpm) by multiplying the gallons pumped in 15 seconds by 4. The result is in gallons <br />per minute. <br />3. Increase or decrease the pressure if necessary to change flow as needed. This is accomplished with rotary <br />switch SW 1 (ref. Table 4 on page 9). <br />4. Repeat the Flow Calibration Test after every adjustment of pressure and until flow rate does not exceed 10 <br />gpm. <br />28 <br />
