How to close the roof without breaking the telescopes
First put the telescopes in a safe position
Try the following steps, in this order, until the telescopes are in a safe position, i.e. approximately horizontal.
- Run the command slew stow in any terminal window on the TCS machine (computer keyboard/screen nearest the door). The username/password is written on the white board.
- If this command does not work, try the command "park" in any terminal window.
- Check that the telescopes are out of the way of the roof. If not, use a 13mm spanner to loosen-off the RA and Dec drive clamps and move the telescopes to a safe position by hand. Remember to tighten (but don't over-tighten) the drive clamps afterwards. There is a tool box on the floor in the mount room.
Close the roof
Try the following steps, in this order, until the roof is closed.
- On the observer machine, enter the command "close_roof" in any terminal window. (Same username/password as tcs).
- If this does not work, use the grey box on the wall of the computer room to close the roof.
- Press "START" to power-up the hydraulics
- Hold the "CLOSE" button until the roof is closed
- Press "STOP" to shut-down the motor.
- Twist the STOP button to release it when you have finished.
- In an emergency only e.g. if there is no power, you can use the spanner next to the box WEATHER STATION POWER SUPPLY to undo the 3 bolts that hold the roof onto the hydraulic ram and push the roof closed by hand (this is a two-person job).
