Illustration 5-1 Operating and display elements
Because of constant improvements aimed at optimum use of the RPS3 25M system, the Solaris R3 controller
has been equipped with an update function. Consequently some of the functions described in this chapter are
only applicable to certain software versions. These functions are separately identified by symbols.
Software updates to the Solaris R3 controller may only be carried out by the ROTEX service technician.
The mains switch disconnects the Solaris R3 controller completely from the mains supply. Operating the mains
switch requires greater pressure than actuating the operating buttons does.
