hager TX216 KNX/EIB DALI-Gateway - UTU

hager"DALI Gateway C00Cx2" softwareFunctional descriptionFeedback for DALI short-circuitThe DALI Gateway detects short-circuits in the DALI line – for instance in case of an installation error.As soon as a short-circuit has been identified in the DALI line (with mains voltage applied), the DALIGateway will send a feedback to the KNX/EIB if the feedback function has been enabled for a DALIshort-circuit.The DALI Gateway utilizes the independent “DALI short-circuit” 1-bit communication object 212 for aDALI short-circuit feedback. The polarity of the telegram is preset: (no short-circuit = 0, short-circuit = 1)Setting the feedback for DALI short-circuitThe ETS allows to set parameters that determine whether a DALI feedback on a short-circuit is to betransmitted to the KNX/EIB. If enabled, the telegram is always actively transmitted. If a short-circuit hasbeen detected or eliminated, the Gateway will transmit a feedback telegram in each case.• Set the "DALI short-circuit feedback ?” parameter on the "General" parameter page to "Yes".The DALI short-circuit feedback is activated and the communication object is enabled.• Set the "DALI short-circuit feedback ?” parameter on the "General" parameter page to "No".The DALI short-circuit feedback function is deactivated. The communication object is hidden.• The connected DALI devices will also respond to a short-circuit in the DALI line. The devices willadjust to the preset "SystemFailureLevel". This value will be programmed into the DALI devicesduring the commissioning of the DALI Gateway and corresponds to the “Response to bus voltagefailure” value that can be parameterized in the ETS for each group.• Because the brightness of the connected DALI devices might possibly change in case of a shortcircuit("SystemFailureLevel"), the DALI Gateway will also transmit feedback on the switching stateand brightness value to the bus if these feedback functions have been enabled.• Feedback on a DALI short-circuit can only be transmitted if the bus voltage has been connected andswitched on at the time of the short-circuit.In case no bus voltage has been connected or switched on at the time of the short-circuit, there willalso be no feedback transmission. The feedback, however, will be stored so it can be transmitted ata later time after the bus voltage has been applied.• The DALI Gateway initializes after the ETS programming or after the mains voltage has beenapplied. If a short-circuit has been detected in the DALI line, the Gateway will proceed to transmit thecorresponding feedback telegram. The “DALI short-circuit” will not be automatically transmitted to thebus after the return of bus voltage (mains voltage at the Gateway is permanently switched on duringbus failure).Seite 39 von 130
