PLC-5000 Site Controller, LD-2000 and LD-2000 PLC <br /> 5. The submerged pump dispenser switch was shut off and the test was conducted by <br /> the leak detector. <br /> 6. This process was repeated at different temperatures until the requisite number of <br /> tests had been completed over the temperature range specified by the EPA protocol. <br /> A total of 59 tests were conducted in the Monthly/Annual mode on the rigid pipeline. <br /> These tests conformed exactly to the EPA protocol. An abbreviated number of tests <br /> were conducted on the rigid pipeline in the Hourly mode and on the flexible pipeline in <br /> both the Hourly and the Monthly/Annual mode. The abbreviated testing was conducted <br /> at the temperature extremes required by the EPA protocol. This testing was conducted <br /> to verify that the system would perform properly on flexible pipeline and that the 98 LD- <br /> 2000/98 LD-2000 PLC mechanical line leak detector could detect a 3 gal/h leak. A <br /> summary of the tests that were conducted is contained below in Table 1. <br /> Table 1.
