Generac — 12

For these Generac models: EcoGen 6kW Generator, GT-530.

Applies to: Generac Ecogen 6Kw Generator, Generac Gt 530

Procedure

  1. 5. When certain that input voltage is compatible with battery charger ratings, turn OFF the power supply to the generator.
  2. 6. On the generator panel, set the Auto/Off/ Manual switch to MANUAL. The engine should crank and start.
  3. 7. Let the engine warm up for about five minutes to allow inter- nal temperatures to stabilize. Then, set the generator’s main circuit breaker to its ON (or closed) position.  Proceed with caution! Generator power volt- age is now supplied to the inverter. Contact with live inverter parts will result in danger- ous and possibly fatal electrical shock.
  4. 8. Connect the AC voltmeter test leads across terminal lugs E1 and neutral. Voltage reading should be 125-120 volts AC.
  5. 9. Set the generator’s main circuit breaker to its OFF (or OPEN) position. Let the engine run at no-load for a few minutes to stabilize internal engine generator temperatures. 10. Set the generator's AUTO/OFF/MANUAL switch to OFF. The engine should shut down. NOTE: It is important not to proceed until certain that generator AC voltage and frequency are correct and within the stated limits.
  6. 2.4 GENERATOR TESTS UNDER LOAD To test the generator set with electrical loads applied, proceed as follows:
  7. 1. Set generator’s main circuit breaker to its OFF (or OPEN) posi- tion.
  8. 2. Turn OFF all breakers on the load center of the inverter (if equipped).
  9. 3. Set the generator's AUTO/OFF/MANUAL switch to MANUAL. The engine should crank and start immediately.
  10. 4. Let the engine stabilize and warm up for a few minutes.
  11. 5. Set the generator’s main circuit breaker to its ON (or CLOSED) position. The inverter is now powered by the standby genera- tor.
  12. 6. Turn ON the load center of the inverter system.
  13. 7. Connect an accurate AC voltmeter and a frequency meter across terminal lugs at the inverter. Voltage should be greater than 120 volts and frequency • should be 60 Hz.
  14. 8. Let the generator run at full rated load for 20-30 minutes. Listen for unusual noises, vibration or other indications of abnormal operation. Check for oil leaks, evidence of overheat- ing, etc.
  15. 9. When testing under load is complete, turn OFF electrical loads. 10. Set the generator's main circuit breaker to its OFF (or OPEN) position. 11. Let the engine run at no-load for a few minutes. 12. Set the AUTO/OFF/MANUAL switch to OFF. The engine should shut down.
  16. 2.5 CHECKING AUTOMATIC OPERATION To check the system for proper automatic operation, proceed as follows:
  17. 1. Set generator’s main circuit breaker to its OFF (or OPEN) posi- tion.
  18. 2. Check that the AUTO/OFF/MANUAL switch is set to OFF.
  19. 5. Turn ON the power supply to the battery charger, using the means provided (such as a line circuit breaker).
  20. 6. Set the generator's main circuit breaker to its ON (or CLOSE
