* '''LCU connection''': if the LCU drops out, then the telescope will also shutdown.
During the verification period of the LCU, there are tick boxes available to override the LCU and weather shutdowns. Please don't tick the boxes unless you experience spurious shutdowns, and report the circumstances of those shutdowns. '''If the suthweather.saao.ac.za page is down, the LCU will not be able to read the weather and will close the dome''', so you will need to tick the weather override in this circumstance. '''Note that there is no way to override a loss of connection to the user's browser, so you always need to '''ensure that you reload the page if a connection warning appears on the TCS'''.
