M. Final Power Outage Test

• Notify responsible on site city representative of your intentions to cut utility power on those circuits protected by the stand-by generator system. Advise the city representative that there will be at least a 10 second power outage on those circuits.
  
  
• After notification to the city, Use the test switches on the generator switchgear panel to simulate a power outage. Observe the stand-by generator set system to make sure if functions properly. Return the test switch to the normal power position. Observe that the stand-by generator shuts down properly. Make any adjustments necessary.

N. Site Wrap-Up

• Check to insure that all control switches are left in the proper position for automatic stand-by power protection.
• Complete all routine maintenance check lists and summary reports.
• Discuss the system condition with on-site personnel leaving with them copies of the maintenance check list. Insure a copy of the summary report is attached to the generator set.

O. Full Power Load Bank Test

A full power load bank test, using vendor supplied external test equipment and cables, will be conducted once per year.

• Connect the vendor supplied load bank to the system. Do not disconnect the generator set from the stand-by system to accomplish this hook-up.
• Exercise the generator set under load for no less than two hours. No less than one hour of this test should be at 100% of the generator set's name plate rating.
• Record the following areas of generator set performance:
  
  
• Load expressed as a percentage of maximum generator set rating
• Voltage
• Amps (all 3 legs if 3 phase)
• Frequency
• Oil Pressure
• Coolant Temperature
  
  
• Note both time and effect of any adjuestments attempted on the generator set during this test.
• At the conclusion of this test, disconnect the load bank and allow the generator set to run for ten minutes to cool down.
• Disconnect all external load test equipment and cables from the stand-by system leaving the system ready to respond automatically to a power outage.
• Leave the site in a state of good order and cleanliness.
• Write a load bank test report.

P.Coolant Change

• Replace coolant with 50% 50% water and new (not recycled) antifreeze mixture.
