Mounting on the telescope

1. Power off the motor controller. (Also the detector controller, if this one had been left on.) Disconnect power cables. Disconnect the orange network cable from the plug in the dome wall. If the optical fibers are connected in storage mode, then disconnect them at the junction between the grey and the orange optical fibers before mounting NOTCam. Don't disconnect at the controller end! Remove the black instrument cover completely.
   
   
2. Move NOTCam towards the telescope while lowering the PTR hoses which have been lifted towards the dome ceiling. Detach the hoses completely from the hook and lay them on the floor. Raise the hook up again in the high position and fix it. Be careful when handling the hoses! Avoid sharp bends that may produce Helium leaks, and make sure they have a maximum of one loop when NOTCam is mounted!
   
   
3. Take off the lid that covers the entrance window. Makes sure there is no obvious dust particle on the entrance window. If so, blow carefully dry air across it. Don't touch the window.
   
   
4. NOTCam should be oriented with the tubes sticking out towards the lower hatch direction, and the PTR hoses should have a maximum of one loop. This is normally achieved by rotating the instrument only about 90 degrees from its orientation when parked, while it is moved over the floor - provided that NOTCam was dismounted and parked correctly. If not, you may have to turn it more to get rid of loops.
   
   
5. There are mounting marks on the instrument and on the adapter plate. Use the handle to lift NOTCam on its trolley (but don't wind it too rapidly as the chain may jump off its rail). Mount the instrument flange to the adapter with the 11 different screws found in a plastic bag on the NOTCam trolley. The differently coloured screws are of different length and should go to the positions as marked on the flange. The red screw is to be used just below stancam and has to be fixed with a bolt at the upper side of the adapter plate (use key hanging behind entrance door). Before taking the trolley away, fix the red and the yellow screws plus the two grey at the two corners of the trolley towards stancam. Then remove the trolley and put in the remaining 4 grey ones. Note that currently one hole in the adapter plate is damaged!
   
   
6. Mount the arm for the extra weights with 3 screws. The arm will stick out towards the StanCam metal triangle. One of the 3 screws is 70mm long, while the others are 60mm. Their position is marked on the arm. Put on 45 kilos, i.e. 4 disks of 10 kg each and 2 of 2.5 kg.
   
   
7. Check and connect cables:
   • The double optical fiber between the detector controller and the marissa computer in the electronics room is now the direct fiber going through the hole in the floor (since summer 2011). Make sure the orange fiber on the floor is well protected and long enough for telescope movement. Connect it to the grey optical fiber which comes from the array controller (blue to blue). Tie it up.
     
   • Connect the orange network cable to the 3Com network switch on the adapter (any slot). Make sure the other end is connected at the black small box called NPort 5210 next to the NOTCam motor controller.
     
   • Make sure the shutter cable between the motor controller and the array controller has been connected. For shutter monitoring in the control room, find among the cables coming through the hole in the floor a grey cable marked NOTCam (Spare) and connect it to the motor controller in the slot named "SPARE". Tighten it with a screwdriver.
   • Connect the black power cable to mains in the adapter. This cable connects to the instrument via a rack of sockets. Make sure the switch is on!
   
   
   
8. Make sure that the required LN2 for the night has been filled already (it is not advisable to fill it just before mounting). Put the special cork in the fill tube. NB! Only so far that just one black ring is inside.
   
   
9. Power on the motor and detector controller units.
   
   
10. In the control room see Start-up NOTCam to start the software. Make sure that both the camera and the motor controller respond. Check that there are no timeout on any wheels. Take an image, e.g. dark 0 to check that the array reads out well. Note that the first one is always crap, so take a few.
    
    
11. Switch on the "NOTCam buzzer" on the wall behind the Lisa terminal. This is the shutter monitoring alarm.
    
    
12. Balance the telescope. Set the counter weights to position 0.95 by typing on the TCS the command count-w-hei 0.95 .
    
    
    • You can check how well the telscope is balanced by putting the telescope to alt 60 (zenith angle 30) and opening the mirror covers (o-m-c), and then look at TCS status page 3, where the currents to the two altitude motors are displayed. These currents (Altitude Motor 1 and 2) should have approximately equal absolute values. Then type zenith to put the telescope back.
    
    
    
13. The default telescope focus is 23450, and set with the command foc-pos 23450. This should be close to the real focus for the WF camera and any of the K-band filters and is set automatically when running tcs.setup-tel-notcam.
    
    
14. Check web page: First night NOTCam goes on telescope for the tests to be done in the afternoon and on the sky after every mounting of NOTCam.
