Shut-down and dismount



    In the control room:

  1. Type shutdownobssys notcam in an xterm. Wait until the whole data acquisition system has been shut down completely.

  2. Switch off power to the NOTCam shutter monitor ("the buzzer") which is on the wall behind the Lisa terminal.

    In the dome:

  3. Switch off power both to the camera controller and the motor controller. Disconnect the power cable from the 220V outlet in the adapter.

  4. Disconnect the double optical fiber at the junction between the grey and the orange fibers. Coil the orange fiber up nicely and protect it in the hole in the floor. Make sure it is not wheeled over by trolleys etc. Disconnect the network cable from the 3Com network switch in the adapter. Also disconnect the shutter monitoring cable from its slot in the motor controller rack (the cable is marked NOTCam (Spare), and you need a screwdriver), and coil it nicely on the floor.

  5. Take off the extra weights (45 kg) and dismount the arm which is fixed to the NOTCam flange by 3 screws.

  6. Place the NOTCam trolley under the instrument, but remove first the 4 grey screws which are difficult to reach when the lift is all the way up. With the trolley in place and up, remove the remaining screws and leave them in the plastic bag attached to the trolley. For the red screw with a bolt under stancam you need an extra key to be found behind the entrance door. Take the lift down.

  7. Put the lid above the NOTCam entrance window, and move NOTCam to its storage place. If correctly mounted, the PTR hoses should have only one loop on the floor, and moving NOTCam correctly to its park position then involves only about 90 degrees rotation to have the NOTCam tubes sticking out towards the entrance door. NB! Handle the PTR hoses with care and avoid any sharp bends! Lift up the hoses towards the ceiling.

  8. Connect the orange network cable to the network socket on the dome wall.

  9. Connect the power cable to a 220V outlet.

  10. Power on the motor controller!!!. NB! Without this we get no temperature readings from NOTCam and will not know if it warms up!

  11. Put the black cover over the instrument but do not cover the motor controller. Use the rope provided to secure the cover.

  12. Make sure the PTR is running without problems and check that the cooling water temperature is within 10 to 30 degrees (can be checked in the TMS, sensor 367, or directly on the digital display on top of the PTR compressor in the machine room).
