Inspections And Maintenance - Bergey Powersync II Owner's Manual

Owner's Manual
VII. INSPECTIONS AND
MAINTENANCE
The Bergey EXCEL 10 turbine and tower should be inspected 30 days after installation,
and then again 180 days after installation.
Following these two inspections the installation should be inspected every two years
and after any particularly severe weather. Inspections should be done on days when
the wind is below 16 mph (7 m/s).
Check List for Inspections
1. Inspect each of the anchor points. Ensure that all hardware is secure and the guy
wires are properly tensioned. Check to ensure that no strands are broken and the
turnbuckle safety cables are in place.
2. Furl the wind turbine and check that the damper restricts the tail's unfurling to a
period of at least three seconds when the winch cable is rapidly unwound.
3. Disconnect the inverter, furl the turbine and short the alternator using the procedure
given in the installation manuals. Climb the tower. Always use proper safety
climbing gear and safe climbing practices.
4. Inspect the blades for:
A. Cracks outboard of the hub pad, in the blade pultrusion itself. Cracks in
the molded hub pad are normal after a few weeks of operation and will not affect
the strength or reliability of the blade.
B. Condition of the leading edge protection tape. Torn or peeling tape will
need replacing.
C. Leading or trailing edge damage.
D. Condition of the paint.
5. Remove the spinner and hang it from the machine. Check the torque on the blade
nuts; the recommended value is 150 ft-lbs. Check the front bearing for seal
integrity and grease loss. Reattach the spinner and check that it is secure.
6. Open the hatch on the nacelle. Use a small rope to lash the hatch open.
7. At the 180 day inspection only: Inspect the flanged connection between the
mainframe and alternator. Check the torque on each of the bolts; the
recommended value is 80 ft-lbs.
8. Check the rear alternator bearing for seal integrity and grease loss.
