== Shutdown recipes ==
=== Shutting down using the SHUTDOWN button ===
# Ensure that you can see the feed from one of the webcams.
# Click the '''SHUTDOWN''' button on the bottom right of the TCS screen. This will switch on the slew lights so you can watch the mirror & baffle covers close, the dome shutters close, the telescope and dome park, then the slew lights switch off. A blue progress circle will rotate on the button while all the commands are executed; it will disappear once the shutdown procedure is complete.
# On the central panel of the TCS "Controls" tab, check for grey or orange indicators showing the status of each subsystem: telescope Tracking = Off (grey); Mirror covers = Closed (orange); Dome (orange) Tracking = Off (grey) and Shutters = Closed (orange) [the arc indicating the shutters on the schematic will also turn red].
# On the left-hand panel of the Controls tab, there should be a message in orange stating "Unpark telescope to slew", indicating that the telescope is parked.
# If any of the above is not in the correct state, you can rectify it using the relevant buttons on the Advanced tab.
=== Shutting down without the SHUTDOWN button ===
If you woke up the telescope with the STARTUP button, it will have turned into a SHUTDOWN button. If there has been a failure in the nighttime that has resulted in the web server being restarted but the telescope remaining open, the software will forget that the startup procedure was run before the crash, so there will be no shutdown button. Here you have two choices: if there is no urgent reason to close (e.g. bad weather), you can press STARTUP and wait for the commands to execute (even though everything is already running), then close up using the subsequent SHUTDOWN button. The alternative is to shutdown each subsystem individually from the Advanced tab of the TCS:
# Ensure that you can see the feed from one of the webcams. On the TCS Advanced tab:
# In the central Dome panel, turn the Slew lights "ON".
# In the left-hand Telescope panel, click Mirror Covers "CLOSED" and wait for the "OPEN" button to turn grey.
# In the central Dome panel, click "CLOSE".
# In the left-hand Telescope panel, click "PARK TELESCOPE".
# In the lower left Rotator panel, click Tracking "OFF".
# In the central Dome panel, click "PARK DOME".
# Check the webcam image for a closed dome and a parked telescope.
# In the central Dome panel, turn the Slew lights "OFF".
# On the Controls tab of the TCS check for grey or orange indicators showing the status of each subsystem: telescope Tracking = Off (grey); Mirror covers = Closed (orange); Dome (orange) Tracking = Off (grey) and Shutters = Closed (orange) [the arc indicating the shutters on the schematic will also turn red].
# If any of the above is not in the correct state, you can rectify it using the relevant buttons on the Advanced tab.
