Mounting MOSCA

1. Lock the telescope by pushing the red emergency button in dome and place the Don't move the telescope sign on the TCS keyboard.

2. Check the CCD window and blow off any dust/spiders/bugs with clean air. Note that the only way to remove "a bug with wings" or a spider during an observing run is to lower the instrument and remove the offending bug. (Don't shake the air bottles and don't hold them upside down.)

3. If FASU is not mounted see Mounting the FASU and the ALFOSC.

4. Roll MOSCA under FASU and align the yellow mounting mark

5. Bolts: red, NO washer (don't screw into the places marked for counterweight)

6. Mount the MOSCA counterweight holder at the position marked by black lines. Bolts: White without washers. White with red stripe in middle position.

7. Put MOSCA counterweights on the holder (22.5 kg) and secure them using the big wrench. Remember to put on protective cover on the holder.

8. Plug in the power cables for FASU and MOSCA. You will have to find one loose 220V power cable in the cabinet.

9. The shutter cable: connect it from FASU controller to MOSCA controller (label shutter)

10. Optical fiber: Connect it from MOSCA controller to the fiber link box (see the labels)

11. The cable from the FASU MOXA black box to the FASU motor controller: Make sure it is connected to the FASU motor controller.

12. The network cable: Connect FASU unit to the network switch on the rotator (if not connected already).

13. Turn FASU and MOSCA power on

14. IMPORTANT!!!! check that the FASU HANDSET is switched on the Remote position

15. Balance the telescope and set the default focus
