Appendix B: Shutdown Checklist
Telescope
- Stow the telescope at the zenith (Dec=31:57) :
Telescope Control System
- In the new TCS GUI turn the track OFF by clicking track
button.
- Send dome to the home position (51 deg.) via the TCS GUI (home) button.
Computers and Instrumentation
- Fill instrument dewar with liquid nitrogen if required.
- Leave the Linux workstations and X-windows running
including the TCS GUI and server.
- When did you last backup your data to DVD
on hill?
- Did you remember to turn off the dome flat field lamps if
used?
MIS and Guider
- Close the MIS hatch.
- Are all the spectral lamps / flat field lamps turned off?
- Turn off the following units located in the observing room:
- GUIDE CAMERA POWER SUPPLY.
- GUIDE MONITOR.
Dome
Mske sure mirror covers are closed via the Mirror button in
the TCS GUI
- Check that the dome is at the home position (51 deg.) and contactors are aligned. If the
contactor box is mis-aligned:
- Rotate the dome manually from the dome control panel.
- Close the drop-out shutter first then the main shutter.
- If they won't close or are intermittent the contactor
box is not
properly aligned.
- Close all the dome doors
- Re-check that you turned off the LN2
storage dewar after filling
the instrument!
- Turn on Air conditioner.
- VERY IMPORTANT: Press the E-stop button in the dome by
the double doors! This will disable the telescope (a red light will be illuminated when E-stop is engaged).
Conserve Energy!
- Turn off all the lights. This a) saves money and b) keeps
down
the potential load on the generator, which may fail to start
automatically when too heavily loaded.
