If it attempts to conduct a test while AC power to the submersibles is OFF, a Use self test Mare will occur and the appropriate alarm indications will be triggered. If Me Leak Lockout Tbaes art p ed into the ayzWn4 be slue that power to submersible pumps is W1 shut OFF before the lockout start time and that power to the submersible pumps is turned ON before the lockout stop time. . The EMC Line Leak Detector will attetmpt to conduct a 3.0 gall hour (GPH) line leak test after every dispensing UmsactiolL It WM also attempt to automadesIly conduct a 02 GPH test once every 24 hours. In addition, the rYSUM can be programmed to conduct a 0.2 GPH or 0. i GPH test at predetermined Unift The EMC Ltne Leak Detector will automatically shut down a submersible pump if a 3.0 Gbit leak is detected. The system can also be programmed to shut down the submersible it a 0.2 GPH or 0.1 GPH leak is detected. 1. 8.0 Ganonr-Per•Hoar Line Leak Test The EMC Line Leak Detectcs WM aftenWt to conduct 13 0 GPH line leak test at the end of each dfsp on — not to.*xceed two completed tests per halt" hour. When all dispenser handle switches far a pariicub+r product are in the off position, the system deteradnes if a 8.0 GPH test can be run or if it is' necessary to wait for Biel temperature to stabilize. If no waiting is required, the 3.0 GPH test is started. If a dispenser switch is turned on during the test, the teat is aborted until dispensing is finished. When dispensing is a new test is started. If a wait time Is , the systems riots a five6econd test to verify that no catastrophic leak exists, When the wait time is complete, the system begins the 30 GPH test. NO "TEST PASSED" REPORT will be printed for a sucoesstu18.0 GPH or ficve-second test. a. Lt' leak is not detected during the 3.0 QPH test, the system oonducts. a self test. If the self test is suoce mful, the system conducts a pumpside pressure test. If the pumpside pressure test is successful, the system conducts a pumpside self test. if the system fails any of the self tests or pumpside test, you must call a trained technician who can v%* and correct the problem before re -enabling the line leak detector. b. If a 8.0 QPH or greater leak Is detected:- 1. etected:1. Tile systems triggers its audible and visual alarms and shuts down the submesaible pump. 2. Press the ALARWrEST button to silence the audible alarm, 3. The display will show: START LEAK VERIFICATION 4. Cover the dispenser handles or take other mere to prevent them from being lifted. Press ENTER to begin the Leak VeziSmtfon Proftilme CLQ tet` If a pump handle is lifted during the LVP test, the submersible will again be shut down and the alarms reactivated. c Xt le" is not detected dtuiug the UP, the system conducts a self test.

If the system fails any of. these tests, you must calla trained technician who can verify and correct the problem befbre re -enabling the line leads detector. 2. Automatic 0.2 Galion -Per -Hour Line Leak Test: The EMC will automatically attempt to run a 0.2 GPH line teak test once every 24 hours. The test is not considered valid until the full line leak test, self test and pumpside test are completed. If a leak is detected, the system automatically performs a Leak Verification Procedure test no operator intervention is required. If the automatic 0.2 GPH line leak test or automatic LVP test is interrupted by a request for Mel, the system will oorxtutue to attempt a new test or to complete the LVP test. If a leak is confirmed, the leak alarm is triggered. Note- The automatic 0.2 GPIs line leak test will shut idown the submersible after a leak has been detected only if that option has been programmed into the system during setup. Self tests will shut down the submersible only if the line Test has been programmed to do so. 8. programmed 0.2 and 0.1 Callon-PerHour Line Leak Tests The EMC can be programmed to conduct 0.2 GPH or 0.1 GPH line leak tests aMdally, monthly, weekly or daily at selected times. All test procedures are the same as for the Automatic 0.2 GPH Lure Leak Test except: If the test is interrupted, the system will not attempt to run a new test. A `Test Interrupt" report will be printed if the PAC E4 equipped with a printer and the Warning tight and audible aurin will be triggered.
