4,4FREDJACKET-0CPT Controller Manual <br /> Processor Board <br /> i <br /> The Processor board contains two microprocessors. These <br /> microprocessors control the frequency of the power sent to the <br /> motor windings, process the pressure information from the <br /> transducer, and analyze it in accordance with Marley Pump <br /> Company's patented high-pressure line-leak detection software. <br /> The Processor board has an RS-232 port, which allows <br /> communication with another CPT pump in a tandem pumping <br /> situation. <br /> Pressure Transducer and Intrinsic Safety Barrier Kit <br /> { The pressure transducer consists of a <br /> 0-50 psig pressure transducer with <br /> a 0-5 VDC output.` This is the same <br /> transducer as used in other Red Jacket <br /> electronic line-leak detection systems. <br /> r< . ., An Intrinsic Safety Barrier Kit must be <br /> .:.Y.. r installed at the appropriate place (see <br /> installation instructions in chapter 3). <br /> F/GURE2.3 PRESSURE TRANSDUCER <br /> Tech Pod(Optional) <br /> The Tech Pod is an optional user interface tool that is available for <br /> setting parameters in the CPT Controller and for monitoring its <br /> performance. (See the "Tech Pod User's Guide"for information on <br /> how to operate it.) <br /> ) <br /> Chapter 2: Red Jacket CPT Controller 2-4 ARE260-240 Rev.A ♦ 6/97 <br />
