Autofib 2/WYFFOS Telescope Instrument Setup Procedure

Section 4 : Installing AF2 part 1/2

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

IMPORTANT Great care must be taken when placing the PFU in the telescope. This is because the crane beam and telescope axes are not orthogonal.

Fitting Prime Focus Unit.(PFU)

  1. Check that the lifting frame centre of gravity is correct for the PFU.
  2. Lift Unit from Ground floor.
  3. Secure PFU to telescope with six bolts.
  4. Lower PFU lift frame to ground floor.
  5. Connect cables from telescope to PFU.
  6. Turn on PFTT power amp in control room and ensure you can rotate the PFU locally.
Fitting AF2 Robot
  1. Lift AF2 robot from the ground floor to AP3.
  2. Offer AF2 up to PFU unit. Move PFTT until the dowels align.
  3. Secure AF2 to the PFU.
  4. Are all bolts tight?
  5. Lower lifting frame to the ground floor.
  6. Fit robot cables between AF2 and top ring patch panel.
  7. Connect compressed air supply to robot.
  8. Cover small or large fibre module sensor (depending on which fibre module is being fitted.) with a piece of metal.
  9. Ensure all staff are clear from the robot, as it can move without warning.
Test that the robot works with a telnet session to the AF2 VME
  1. Telnet 161.72.6.65
  2. OS9> eng
  3. eng> local
  4. eng> wake
  5. If AF2 wakes, then you will hear the gripper jaws actuate 3 times.
  6. eng> sleep
  7. Close telnet session
  8. Remove the metal from the fibre module sensor.
6. Fitting Fibre Module
  1. Two people lift the fibre module out of its box.
  2. Lift the fibre module on to the AF2 robot.
  3. Fit the spacers between the robot and the fibre module.
  4. Secure the fibre module with four cap head bolts and self-aligning washers.
Section 5 contains the second part of the AF2 installation process.
