Air-cooled 11 kW Generators

DANGER

Proceed with caution! Generator power voltage is now supplied to the transfer switch. Contact with live transfer switch parts will result in dan- gerous and possibly fatal electrical shock.

10.Connect an accurate AC voltmeter and a fre- quency meter across transfer switch terminal lugs E1 and E2. Voltage should be 242-252 volts; frequency should read about 61-63 Hertz.

11.Connect the AC voltmeter test leads across ter- minal lug E1 and neutral; then across E2 and neutral. In both cases, voltage reading should be 121-126 volts AC.

12.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.

13.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. Generally, if both AC frequency and voltage are high or low, the engine governor requires adjustment. If frequency is cor- rect, but voltage is high or low, the generator’s voltage regulator requires adjustment.

2.4GENERATOR 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 util- ity main line circuit breaker).

Do not attempt manual transfer switch opera- tion 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, e.g., 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 frequen- cy 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.

2.5CHECKING 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 util- ity power source side.

5.Turn ON the utility power supply to the transfer switch, using the means provided (such as a util- ity 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.
