Generator Tests Under Load; Checking Automatic Operation - Generac Power Systems ECO GEN Series Installation Manuallines

Even if the generator is running smoothly at this
point, a drop in gas pressure indicates that the sup-
ply is barely adequate to supply the generator's
needs. Changes in the generator load, or additional
gas demand by other appliances may affect the gen-
erator's performance. Verify gas pressure and pipe
sizing. Unhook the manometer and reinstall the port
plug.

GENERATOR TESTS UNDER LOAD

1. Test the generator with electrical loads applied, start
by placing all of the breakers on the Alternative Power
Management System into the OFF or open position.
2. The disconnect switch recommended to be installed at the
generator input to the Alternative Power Management System
should be switched to OFF or Open position.
3. Place the main Circuit Breaker on the generator in the ON or
closed position.
4. Set the AUTO/OFF/MANUAL switch to MANUAL. The
generator should crank and start immediately. Let the engine
stabilize and warm up for a few minutes.
5. Check voltage and frequency at the disconnect switch
installed between the generator and the Alternative Power
Management System.
6. If the appropriate voltage and frequency are present, close the
disconnect switch.
7. Check voltage and frequency at the Alternative Power
Management System by closing the breakers one at a time. (if
applicable)
8. Let the generator run under load for 20-30 minutes while
listening for any unusual noises, vibration or other indications
of abnormal operation such as oil leaks or overheating.
NOTE:
9. With the generator carrying the entire priority load, recheck
gas pressure to verify that it is at the same level it was before
the generator was started.
10. When completed, open the disconnect switch and allow the
generator to run at no load.
11. Place the AUTO/OFF/MANUAL switch into the OFF position.
The generator will shut down. Return to the disconnect
switch and place it in the ON or closed position.

CHECKING AUTOMATIC OPERATION

1. To check the automatic operation, place the AUTO/OFF/ON
switch to the AUTO position.
2. Verify the remote two-wire start test switch that's installed
near the Alternative Power Management System is set to the
ON or closed position. This will cause the generator to start
automatically.
3. With the generator running and powering loads, set the
remote two-wire start test switch to the OFF or open position.
In approximately one minute the generator will automatically
shut down.
