The KELT building roof and lights are controlled by the Control Computer, through the PLC (Programmable Logic Controller).  The PLC sits inside the KELT building, and have manual controls for a local operator to open and close the roof and control the lights.

The PLC also monitors the rain detector and the roof limit switches.
