31604.DSK <br /> WP-SFO <br /> PART 3 EXECUTION <br /> 3.1 FUNCTIONAL TESTING PREPARATION <br /> A. Functional tests are primarily intended to check PLC logic, auto dialer, and <br /> interlock control. <br /> L Make temporary electrical connections necessary to perform functional <br /> tests. <br /> 2. Provide temporary power as needed to complete functional tests. <br /> 3. Make space available at Contractor's or package system suppliers <br /> facility to conduct functional tests. <br /> 4. Prepare functional test schedule and notify both the Engineer and <br /> Owner 5 days prior to testing. The Engineer and Owner shall have <br /> the option to witness functional testing. <br /> 3.2 FUNCTIONAL TESTING <br /> A. The following Tests 1 through 7 shall be completed prior to delivery of <br /> package systems to the project site. <br /> 1. Test 1. Vapor extraction and sparging systems start and stop with a <br /> timed signal from the PLC. <br /> 2. Test 2. Low sparging blower pressure switch activation, signals <br /> extraction blower to stop and notify auto-dialer to send message. <br /> 3. Test 3. High level switch in air/water separator signals auto-dialer to <br /> send message. <br /> 4. Test 4. High-high level switch in air/water separator signals sparging <br /> blower and extraction blower to stop and notify auto-dialer to send <br /> message. Systems restart when level drops below high level. <br /> 5. Test 5. High extraction blower pressure switch activation, signals <br /> sparging blower and extraction blower to stop and notifies auto-dialer <br /> to send message. <br /> 6. Test 6. Low extraction blower intake vacuum pressure switch <br /> activation, signals sparging blower to stop and notifies auto-dialer to <br /> send message. Sparging system restarts when vacuum pressure <br /> resumes. <br /> 7. Test 7. Low oil pressure or high coolant temperature will stop the <br /> engine system and send signal to PLC to notify auto-dialer to send <br /> message. <br /> 3.3 PERFORMANCE TESTING <br /> ' A. Performance testing shall occur after installation of equipment at the project <br /> site. <br /> B. Performance testing shall include the following Tests S through 12. <br /> 1. Test 8. Start sparging and extraction systems and demonstrate that <br /> they comply with the performance specifications for pressure and <br /> flowrate under operating conditions. <br /> 2. Test 9. Demonstrate timed start and stop of sparging and extraction <br /> systems by completing two automatic cycles of start and stop with a <br /> 30-minute run and 30-minute stop during each cycle. <br /> BAE31604.AS.T1 <br /> 01650 3 STARTING OF SYSTEMS <br />
