Autofib 2/WYFFOS Telescope Instrument Setup Procedure

Section 5 : Installing AF2 part 2/2

This sections gives instructions for the second part of the installation procedure.

Fit Ancillary items at top end

  1. Fit the swans neck.
  2. Fit A&G controller support frame and install SDSU controller.
  3. Place the top end ring working platform in place and bolt down
  4. Install  TV camera system with AG1. Make sure the camera sits against the two reference faces. Optimum focus is at 5.42 mm on the micrometer.
Cable-UP Top end.
  1. Prime Focus Unit to AF2 Robot, AG2 acquisition, AG1 tv/autoguiding
  2. Cable up Autoguider.  Fibre connects to prime 1.
  3. Connections to the AG1 TV and interface

 

Connect up Science and Guide TV fibres.
  1. Clear area and ensure only change staff are present.
  2. Lay out all the fibres on the floor.
  3. Run the red science fibres from AF2 up to the topring
  4. Run the grey guide fibre to the  AG1 TV.
  5. Great care must be take when handling the fibres.
  6. Using cable ties secure all the fibres  at the end of the swan's neck. Ensure the cable ties are on the metal part not on the grey mesh.
  7. Very important. Move rotator locally to +/- limits. Check fibres twist OK. When A&G is at the top the rotator PA should be 90 degrees.
  8. Remove top end ring working platform.
Balance Telescope.
  1. Drive weights to the bottom.
  2. Paper calculation on moments removed and added.
  3. Release telescope ties when you are sure telescope is near to balance and slightly bottom end heavy.
  4. Check top to bottom
  5. Check across cube
  6. Check top to bottom
This concludes the Installation of AF2 on to the telescope.  The final thing to do is to check that the instrument works, see Section 6
