USB device failure
If a USB device fails (i.e. the Web cam freezes or there is no image, the USB I/O screen does not respond to commands or the CCD camera fails to respond, follow the procedure in the link above.

__Telescope will not park__
If the telescope did not PARK at the end of an ACP run, then it may have been opened manually in the Observatory Auxiliary Control screen, and the telescope moved to an objcet using Cartes before the ACP run was started.

To PARK the telescope not using ACP, maximise the Sitech controller software (V0.53H in the menu bar) and click on PARK. Watch the Observatory Auxiliary Control screen and Web cam for status.



If this does not work, and If the weather is good and NO rain is forecast, then leave the telescope to close itself automatically. Either at sunrise (by the light sensor in the weather station) or by the rain sensor (if it does happen to rain).

If the weather looks like it is turning BAD……Call me!!!!!!!! (so long as it is not too late)

__Dome will not close__
The Dome will normally close when the telescope is parked.

If the telescope will NOT park, then the dome will not close unless it is bad weather or it is near sunrise.

If you need to close the dome, follow the instructions in the ObservatoryAuxiliary Control section.

If the Dome door will still not close, look at the web cam and see if the LOWER shutter is closed (in the UP position) This may indicate a mechanical failure of the UPPER shutter.

__Dome still open__
Follow the instructions above and see if you can close the dome by parking in ACP.

If that does not work try closing the dome by parking the telescope manually using the Sitech control software.

Otherwise follow the instructions in the Observatory Auxiliary Control section.

If that does not work……Call me!!!!!!!! (so long as it is not too late)

__Dome will not open__
Check the status of the Observatory Auxiliary Control screen and the LED indicator panel lights in the web cam to see if the weather is BAD.

If the weather it is BAD tough!

Check [] on the web to see what the satellite weather images looks like, and check [] for the present forecast local to the Observatory.

__ACP script fail__
The following is in a text file called ACP-ScriptFail and has been placed in the root of ACP in windows programe files.

This script will park the telescope in the event of a script fail
