OPERATION
Manual Operation of Skystream
Manual shutdown of the Skystream turbine is possible by using Circuit breaker that is between the
turbine and the grid. Whenever the turbine looses the grid, it shuts down immediately.
To stop Skystream, switch the ci
rcuit breakers to “OFF,” and to restart Skystream switch the circuit
breake
rs to “ON.” Note that Skystream may require approximately 5 minutes to restart after the circuit
breaker is switched “ON.” Note that whenever Skystream loses contact with the utility grid it will shut
down. Refer to the “Key Operating Characteristics” section of this manual for details.
An “ATTENTION” label, shown below, is provided to indicate the location of the AC power disconnect
switch or circuit breakers. Apply the label in a prominent location where it will be seen by operators or
service personnel.
Maintenance
After 20 years of service the blades MUST be replaced
– even if there is no apparent damage.
The blades should be replaced as a set.
Do not attempt to replace individual blades. All blade mounting
hardware
– bolts, nuts and washers – should be replaced at the same time. Do NOT
attempt to reuse
the blade fasteners.
There are no periodic service requirements other than replacing the blades after 20 years. All bearings
and rotating components were designed for a 20-year life at an IEC Wind Class II site, under the IEC
61400-2 Small Wind Safety Standard. This corresponds to a site with an average wind speed of
8.5 m/s.
Although there are no routine service or maintenance requirements, Skystream owners should be
observant of any unusual sounds, vibrations or erratic behavior. If unusual behavior is noticed, the best
course of action is usually to shut down the turbine and contact the dealer or service center.
One area of Skystream that may experience damage is the blades, for example from flying debris
during a high wind storm. For this reason XZERES wind recommends Skystream be shut down on an
annual basis and an inspection of the blades performed. The inspection may be accomplished using
binoculars or by close visual inspection. Inspect for cracks and chips particularly along the edges of the
blades. Any damage is cause for replacing the blades. If in doubt, contact your local service center
(centre).
