Carrier Air-cooled 7 kW, 12 kW and 15 kW Generators

1.4GENERATOR TESTS UNDER LOAD

To test the generator set with electrical loads applied, proceed as follows:

1.Set generator’s main circuit breaker to its OFF (or OPEN) position.

2.Turn OFF all loads connected to the transfer switch terminals T1 and T2.

3.Set the generator's AUTO/OFF/MANUAL switch to OFF.

4.Turn OFF the utility power supply to the transfer switch, using the means provided (such as a utility main line circuit breaker).

Do not attempt manual transfer switch operation until all power voltage supplies to the transfer switch have been positively turned off. Failure to turn off all power voltage supplies will result in extremely hazardous and possibly fatal electrical shock.

5.Manually set the transfer switch to the STANDBY position, i.e., load terminals connected to the generator's E1/E2 terminals. The transfer switch operating lever should be down.

6.Set the generator's AUTO/OFF/MANUAL switch to MANUAL. The engine should crank and start immediately.

7.Let the engine stabilize and warm up for a few minutes.

8.Set the generator’s main circuit breaker to its ON (or closed) position. Loads are now powered by the standby generator.

9.Turn ON electrical loads connected to transfer switch T1 and T2. Apply an electrical load equal to the full rated wattage/amperage capacity of the installed generator.

10.Connect an accurate AC voltmeter and a frequency meter across terminal lugs E1 and E2. Voltage should be greater than 230 volts; frequency should be greater than 58 Hertz.

11.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 overheating, etc.

12.When testing under load is complete, turn OFF electrical loads.

13.Set the generator's main circuit breaker to its OFF (or OPEN) position.

14.Let the engine run at no-load for a few minutes.

15.Set the AUTO/OFF/MANUAL switch to OFF. The engine should shut down.

1.5CHECKING AUTOMATIC

OPERATION

To check the system for proper automatic operation, proceed as follows:

1.Set generator’s main circuit breaker to its OFF (or OPEN) position.

2.Check that the AUTO/OFF/MANUAL switch is set to OFF.

3.Turn OFF the utility power supply to the transfer switch, using means provided (such as a utility main line circuit breaker).

4.Manually set the transfer switch to the UTILITY position, i.e., load terminals connected to the utility power source side.

5.Turn ON the utility power supply to the transfer switch, using the means provided (such as a utility main line circuit breaker).

6.Set the AUTO/OFF/MANUAL switch to AUTO. The system is now ready for automatic operation.

7.Turn OFF the utility power supply to the transfer switch.

With the AUTO/OFF/MANUAL switch at AUTO, the engine should crank and start when the utility source power is turned OFF. After starting, the transfer switch should connect load circuits to the standby side. Let the system go through its entire automatic sequence of operation.

With the generator running and loads powered by generator AC output, turn ON the utility power supply to the transfer switch. The following should occur:

•After about six seconds, the switch should transfer loads back to the utility power source.

•About one minute after retransfer, the engine should shut down.

1.6ADJUSTING THE REGULATOR

(NATURAL GAS ONLY)

Although the generator has been factory set to provide maximum power, it may be necessary in some areas to adjust this setting. Because natural gas has different BTU or power content across the country the engine may not perform as designed.

If experiencing engine problems at high or full load conditions follow these steps. It will require a frequency meter to perform this procedure.

1.Turn off utility power to the main distribution panel in the house. This can be done by switching the service main breaker to the off or open position.

2.Allow the generator to start. Before loading the generator, confirm that the No Load Frequency, with the top open and front panel off, is set to 63-63.5 Hz. Transfer load to emergency circuits.
