I PEIIRP1200-17 NOTE: To do this, direct the fluid flow into a graduated cylinder while timing for 60 seconds. 9. Continue to adjust the size of the test appa- ratus leak orifice until the desired volume is achieved. To expedite calibration, make coarse adjustments by measuring the volume of fluid that corresponds to the 15 -second time interval indicated in Table 9-1. The final calibration of the test apparatus leak orifice must be con- ducted by measuring the appropriate volume of fluid over the full 60 -second timeframe. 10. Without adjusting the test apparatus leak ori- fice after it has been properly calibrated in Step 9, hang up the dispenser nozzle, allowing the pump to turn off. LL While directing the fluid flow from the leak test apparatus into the test can, observe that the ELLD turns the pump on and pressurizes the line. 12. Confirm that the simulated leak condition causes the electronic line leak detector to alarm and/or shut down the pump. FIGURE 9-3. The test port on the shear valve under the dispenser provides a location to simulate a leak in the underground piping system. ® pei.org NOTE The ELLD may cycle the pump on/ off several times before alarming or shutting down the pump. 13. Record the number of test cycles observed before alarm/shut down occurs. NOTE: When required, perform a 0.2 gph or 0.1 gph simulated leak test on ELLDs. Follow the manufacturer's test parameters. The ELLD safety and test set up procedures for 3.0 gph simulated leak test should be followed. 9.2.7 Pass/Fail Criteria. If the ELLD has iden- tified the simulated leak by generating an alarm and, if applicable, shutting down the STP, the ELLD passes the test. If the ELLD has not identified the simulated leak by generating an alarm and, if applicable, shutting down the STP, the ELLD fails the test. If the STP does not properly cycle on/off under normal fuel system operating conditions, the ELLD fails the test. NOTE: If the leak detector initially fails the test, repeat the test procedure before declaring the test result as "fail." 9.2.8 Restore the System to Operational Con- dition. Upon completion of the test: • Shut off power to the STP and perform lockout/ ragout procedures on the circuit breakers. Allow line pressure to bleed off to zero and close the shear valve. • Remove the test apparatus from the shear valve body and properly reinstall the plug into the shear valve test port. • Reestablish power to the STP, tum dispenser on and confirm that no leaks are present in the system. • Dispense product into the test can to remove any air from the line and confirm that full product flow is achieved.
