Automatic Operation Test (Load Transfer); Generator Load Test (Full Rated Electrical Capacity And Fuel Consumption) - Briggs & Stratton 040213 Service And Troubleshooting Manual

CAUTION
: Do not proceed until you are certain that
generator no load AC voltage and frequency are
correct and within stated limits.
11. Set the SYSTEM switch to
The unit should shut down.

Automatic Operation Test (Load Transfer)

To check the system for proper automatic operation:
1. Ensure that utility power is connected to the
4 UTILITY CONNECTION lugs of the automatic
transfer switch.
2. Ensure that the main line disconnect for UTILITY
POWER is set to
3. Set the generator SYSTEM switch to the AUTO
position.
The standby generator is now set for automatic
operation.
4. Set the main line disconnect for UTILITY POWER
to .
OFF
The engine will crank and start once the utility voltage
drops and the (brown out) sensor has timed out. After
starting, the transfer switch will relay circuit loads to the
generator. Let the system go through its entire automatic
operation sequence.
5. Inspect protected loads and ensure that all
anticipated circuits are functioning.
6. With the generator supplying power, turn
main line disconnect (UTILITY POWER).

NOTE
: If the unit has run for 5 minutes or more,
it will transfer the load back within 10 seconds. If
the unit has run for less than 5 minutes, it will
continue to run for approximately 5 to 6 minutes
(to warm up the engine) and then transfer the
load back to UTILITY POWER.
• About one minute after re-transfer, the engine will
shut down.
This completes the test procedures for automatic
operation. The Home Standby Generator System will
now start automatically when UTILITY POWER is lost
and will supply STANDBY POWER to the protected
circuits in the home.
Generator Load Test (Full Rated Electrical
Capacity And Fuel Consumption)
To test the generator output with electrical loads applied,
proceed as follows:
1. Set the generator's main circuit breaker to
2. Set the generator's SYSTEM switch to
3. Set the main line disconnect (UTILITY POWER) to
.
OFF
4. Set the generator's SYSTEM switch to
The engine should crank and start immediately.
• Let the engine stabilize and warm up for a few
minutes.
5. Set the generator's main circuit breaker to
Standby power is now being supplied to the
GENERATOR CONNECTION lugs of the automatic
transfer switch.
the
6. Turn individual loads within the protected
ON
circuits. Continue until the full rated output of the
generator is reached.
7. Use an accurate AC voltmeter
check generator output voltage across the
GENERATOR CONNECTION lugs in the transfer
switch.
