Intelligent Building SeriesC-Bus 12 Channel Professional Architectural Dimmer Installation Instructions8.2 Output FaultsIf a short-circuit lamp or output cable is plugged into the dimmer, the circuitbreaker will disconnect the fault from the dimmer. In nearly all circumstances, itis quick enough to prevent damage to the output devices in the dimmer. Insome instances however, a failure may be experienced, although the dimmer istypically robust to this. If an output channel is damaged isolate it with its circuitbreaker.8.3 DMX FaultsThe C-Bus 12 Channel Professional Architectural Dimmers feature a Last Holdfacility that remembers the last received DMX message. In the event of a DMXsignal cable being unplugged or severed, the dimmer will hold the last DMXsignal until a new DMX message is received. The DMX LED will light whenthere is a DMX signal, be off if the dimmer has not received DMX or flashcontinuously if a previously received DMX signal has disappeared.8.4 Phase Fault IndicationThe three green PHASE LEDs on the front panel will light when all three phaseshave power. A missing phase will also be reported as error “E09”.8.5 Error MessagesSeveral messages such as E06 though E09 may appear on the seven-segmentdisplay. These indicate error conditions. The RUN LED flashes rapidly to attractattention. Errors E07 to E09 will disable all the outputs. After properinvestigation, the messages can be erased from the display by holding theCONTROL key while pressing on the FLASH key.
