REDJACKET_ <br /> V� ¢c���cYr'.ona �e <br /> Constant Pressure Output <br /> The Red Jacket CPT(Constant Pressure Turbine)uses Controlled Pressure Technology. This <br /> technology measures the pressure downline from the pump with a pressure transducer.The <br /> controller reads the pressure and then adjusts the fundamental frequency and power applied <br /> to the motor to maintain a constant flow. <br /> Line-Leak Detection <br /> The Red Jacket CPT system can provide compliance with EPA requirements for hourly leak <br /> detection,monthly monitoring of leaks of 0.2 gph or greater,and annual monitoring for leaks <br /> of 0.1 gph or greater. <br /> Hourly Leak Detection:This feature provides positive shutdown when a 3-gph or greater leak <br /> is detected.The 3-gph leak detection feature replaces the mechanical line-leak detector that <br /> was previously installed on the pump. <br /> Monthly and Annual Monitoring: By activating the monthly and annual monitoring capabili- <br /> ties of the CPT,total compliance for lines is possible without the installation of extra hard- <br /> ware on the piping system. <br /> Line Leak Functionality Testing:The manual line testing of the leak detecting system,which <br /> is required by EPA,for hourly monitors can be done by using snap taps installed on the line- <br /> test port of the packer-manifold. The snap tap fittings used with an FXT tester can check the <br /> functions of the leak-detecting system within a few minutes.The FXT tester offers a very <br /> quick and clean functional test of the hourly monitoring feature,in addition to running diag- <br /> nostics,without spilling product. <br /> Stand-alone Pump Operation <br /> The CPT Controller's microprocessors are preprogrammed from the factory for stand-alone <br /> operation. Instructions in Chapter 3 explain how to set the DIP switches for stand-alone and <br /> tandem operation,and instructions in Chapter 4 explain how to set the pump pressure to <br /> achieve the maximum flow rate of 10 gpm per nozzle. <br /> Tandem-Pump Operation <br /> When two CPT pumps are required to maintain proper flow,these units can be programmed <br /> to operate in tandem. The installer can designate one controller as the master unit and the <br /> other as the auxiliary unit. The master controller monitors line pressure to maintain proper <br /> flow. <br /> Whenthemaster controller receives the dispense-enable signal,the primary pump starts.The <br /> controller varies the speed of the pump depending on the pressure in the line.
