Initial Start-Up (No Load) - Briggs & Stratton 21114 Série Manuel D'installation Et D'opération

Initial Start-up (No Load)

Before operating the generator or placing it into service,
inspect the entire installation carefully. Familiarize yourself
with the location of components and the location and
function of the generator controller. Begin testing the system
without any electrical loads connected, as follows:
1. Check engine oil. Add oil if needed. Refer to engine
manual for type of oil required.
2. Set the generator main circuit breaker to OFF (open)
position.
3. Start the generator. When the generator is started
for the first time, air in the gaseous fuel lines will be
purged. This may cause the engine to run rough for a
few minutes.
4. Listen for unusual noises, vibration, or other
indications of abnormal operation. Check for oil and
coolant leaks while the engine runs.
5. Let the engine warm up for 5 minutes.
6. Check generator output at line side of circuit breaker.
No-load voltage should be as shown in the chart
below.
Frequency should be 59.8 - 60.2 Hz for 60Hz
applications.
Frequency should be 49.8 - 50.2 Hz for 50Hz
applications.
NOTE
If the no-load voltage is outside the specified
range, perform the automatic voltage regulator (AVR)
adjustment in Step 8. Do not proceed until the AC
voltage is within the specified range.

7. Check voltage output between each of the circuit
breaker connection lugs and the neutral lug. No-load
voltage should be as shown in the chart below.
8. If necessary, adjust the AVR voltage control (A) to
obtain the range specified. DO NOT adjust any of the
other alternator controls.

9. Make sure that the transfer switch is in the "UTILITY"
position and that there is no load present on the
generator.
10. Set the generator main circuit breaker to ON
(closed) position.
11. Stop the generator.
