This paragraph contains directions for the
inspections that should be undertaken by the mill-
owner/inspector to ensure trouble-free operation
and long-life.
Inspections should be made at least:
- daily
- weekly
Daily inspection :
Mills with remote control should be called up to
check that the mill is running normally.
2
2.8
2.9
Mills without remote control should be checked
visually.
Weekly inspection:
At least once a week the mill should be checked
from the inside while it is in operation.
In this way, any irregularities such as abnormal
noise can be detected. Check that the mill is
facing into the wind and that the turbine module
is secure.
If in doubt, contact Micon.
The following data should be logged:
- monthly production
- monthly downtime
- major faults : In the mill
: In the electricity grid
All such data must be entered once a month
in the logbook.
If any irregularities constantly recur,
Micon's Service Department should
be contacted, so that any faults can be rectified
as soon as possible, or at the next regular
service inspection.
All information on inspection, stops
and service must be noted in the
logbook, which must always be kept
in the mill.
The logbook must include:
* Adjusting data.
* Errors and incidents.
* Maintenance and inspection data.
* Errors found under inspection.
* Changes/Modifications.
* Companies working on/by the turbine.
Inspection
When the turbine module moves to follow the wind
direction, the cables connecting the generator to
the electricity grid can become twisted.
Cable twisting is monitored with the help of sig-
nals from the yaw system, positioned on the yaw
brake.
If the total number of twists exceeds a preset
number, the mill stops automatically and the tur-
bine module rotates back until the cable is free.
At this point, the mill restarts automatically.
Diplay text: Cables twisted (17).
A turn of 360° takes 10 minutes.
If this system should fail, there is an extra backup;
a mechanical safety-contact will activate and stop
the mill automatically.
Fault report: Cables twisted (5).
In this instance, it is necessary to
untwist the cables by manually
yawing the mill until the cables are
free.
