6. Check fan and alternator belts for condition and proper tension (if any).

7. Record engine running time meter reading at start and end of test.

8. Simulate normal power failure from a "cold start" by use of the test switch in the automatic transfer switch or by opening normal power supply to the emergency power supply system (EPSS). Observe and record time delay on start.

9. Record cranking time (terminates when engine starts).

10. Transfer the load to the EPSS and operate the unit under full load for a minimum of 30 minutes. It is important that the unit be operated under load. If a portion of the building load cannot be connected, a resistance load should be used. The electrical load shall be not less than fifty percent of the total connected EPSS load (not less than thirty percent of the EPS nameplate rating and preferably at least fifty percent of the EPS nameplate rating). NOTE: If the generator set is used for standby power or for peak load shaving, these uses shall be recorded and may be substituted for scheduled operations and testing of the generator set if the appropriate data is also recorded.

11. Equivalent loads used for testing shall be automatically replaced with the emergency loads in case of failure of the primary source.

12. Record AC voltage, frequency, and amperage.

13. Record oil pressure, battery-charging rate, and water or air temperature after 15 minutes running time.

14. Verify that battery charger is operating properly.

15. While unit is operating, thoroughly observe operation for any indication of defects or possible malfunctions.

19. Return test switch to normal or reestablish normal power supply at such time as will cause a minimum running time under load.

20. Record time delay on retransfer.

21. Record time delay on shutdown on units so equipped.

22. Verify that transfer switch normal position pilot light is illuminated and isolating switch is closed –standby

(emergency) and system is set for automatic start and transfer.

23. Verify that all alarm pilot lights off.

24. After unit has been operated, check lubricant and coolant according to manufacturer's instructions.

25. Maintain engine log in Generator Room.

26. Clean generator room and remove all debris.

37. Check generator brush appearance and length; verify that brushes are free to move in their holders; check brush spring tension or contact pressure, should approximate 2½ psi.

38. Check and record specific gravity and voltage of each individual cell. Uneven cell specific gravities and voltages indicate trouble or approaching failure. If trouble is due to undercharging, an equalizing charge will restore all cells to normal.

39. Verify that battery cap vents are open.

40. With the battery charger disconnected, conduct a voltage test by measuring and recording the voltage of the battery during the generator starting cycle. An artificial load equal to the full load of the starter to the battery may be used for this test. The battery voltage shall not fall below 2.05 volts per cell while under load.

41. Replace the battery when it no longer carries the proper charge and load capacity. This item will be billed separately if approved by COR with no charge.

42. Inspect and adjust rack on unit injector or fuel distributor pump according to manufacturer's instructions.

Check injector pump and injectors and verify flow rate, pressure and spray pattern.

43. Adjust governor for proper operating speed.

44. Tighten control and power wiring connections.

45. Check the calibration of voltage-sensing relays/devices.

46. Change governor oil. Review the Material Safety Data Sheet (MSDS) for proper disposal of used oil.

47. Inspect and clean generator rotor, stator, and exciter.

48. Clean commentator and collector rings. Check brush wear and tension, in accordance with manufacturer's instructions.

49. Clean voltage regulator.
