Three azimuthal driving gears have been repaired and replaced
in the telescope in the last months. Inspections during the repair
phase
showed serious problems in the general state of the gears. For that
reason
it has been decided:
1)
The operator must shut down observations, if the velocity of the wind is
greater
than 12
km/s.
2)
It is not any more possible to drive the telescope in azimuth with a
speed
higher than 20 degrees/min. That means, the maximum speed in azimuth is
now half of the possible one.
Be aware of
that limitation in
azimuth, when planning your observing sessions for the next time.
The preparations for ordering new gears
are in the final
state. Hopefully we can begin with the installation of new gears at the
end of the year.
