The monthly test of a transfer switch shall consist of electrically operating the transfer switch from the primary position to the alternate position and then a return to the primary position. 2.1.13 Transfer switches shall be subjected to a maintenance and testing program that includes all of the following operations: 2.1.13.1 Checking of connections 2.1.13.2 Inspection or testing for evidence of overheating and excessive contact corrosion. 2.1.13.3 Removal of dust and dirt 2.1.14 EPSS circuit breakers including main and feed breakers between the generator and the transfer switch load terminals, shall be exercised annually with the generator in the "off" position. Circuit breakers should be tested under simulated overload conditions every 2 years. 2.1.15 Maintenance of lead-acid batteries is performed in-house and not part of this performance work statement. 2.1.16 A fuel quality test shall be performed at least annually using ASTM D 975 Standard Specification for Diesel Fuel Oils. Inferior fuel shall be removed and disposed off site. 3 Procedures 3.1 Operation and Testing Procedures: The Contractor shall follow the manufacturer's written procedures and the following as a minimum: 3.1 Perform maintenance per Maintenance Schedule 3.2 Record running time meter (RTM) reading at start and end of test. 3.3 Simulate normal power failure from a "cold start" by use of the test switch in automatic transfer switch or by opening normal power supply to EPSS. 3.4 Observe and record time delay (T/D) on start. 3.5 Record cranking time (terminates when engine starts). 3.6.Transfer load to generator. 3.7 Record alternating current (AC) voltage, frequency, amperage, kW. 3.8.Record initial oil pressure and battery-charging rate. 3.9 Record oil pressure, battery-charging rate, and water or air temperature after 15 minutes running time. 3.10 Return test switch to normal or reestablish normal power supply at such time to cause a minimum running time of 30 minutes under load. 3.11 Record prime mover and ac instruments just prior to transfer. 3.12 Record time delay on retransfer. 3.13 Record time delay on shutdown for units so equipped. 3.14 Place unit in automatic operation mode. 6 Deliverables: 6.1 Schedule of Work: The Contractor shall provide a schedule of work that incorporates all maintenance tasks and their corresponding frequencies. A draft copy of this schedule shall be provided to the Contracting Officer's Representative (COR) two (2) weeks after contract award.
