Intelligent Building SeriesC-Bus 12 Channel Professional Architectural Dimmer Installation Instructions7.0 Priority of Operating ModesLoads connected to the C-Bus 12 Channel Professional Architectural Dimmer arecontrolled by a combination of C-Bus keys, Local Override buttons and/or RemoteSwitch functions. Loads are also turned off when the dimmer overheats or channels aredisabled. The table below shows the priority ranking of the control inputs:* Local Override has priority over normal C-Bus commands received on the bus (suchas those generated by pressing a C-Bus key). Y default, if any channel is in LocalOverride mode and a C-Bus command is received for that channel, the C-Buscommand state will be imposed (“Enable C-Bus Priority” option). This feature can bedisabled in software such that the unit whilst in Local Override Mode will ignore allrelevant C-Bus commands. Please refer to the C-Bus Manual for further informationrelating to the programming of PRO Series dimmer units.Mode Priority FunctionMax Voltage Scaling 1 (Highest) Maximum output voltageChannel Isolated 2 Fault conditionChannel Disabled 3 User disableChannel Curve Scaling 4User selectable dimmingcurvesMaximum Level Scaling 5 Max output levelMinimum Level Scaling 6 Min output levelFlash Channel 7 Flash output to maxRemote OFF 8 C-Bus override OFFRemote ON 9 C-Bus override ONLocal Toggle 10 * Buttons on front panelC-Bus 11 * (Lowest) C-Bus input levelNote:When channels of the C-Bus 12 Channel Professional Architectural dimmer are beingcontrolled by DMX rather than C-Bus the Remote OFF, Remote ON and C-Bus modesare not used.
