The control system includes a first disk rotatably mounted to a support panel and a second disk rototably mounted to the first disk at the axis of the first disk perpendicular to the first disk.

The primary received signals are analog signals which are converted to digital signals. An operator knows the position of the luminaire by manual touch feedback relating to the positions of the first and second disks.
