Configuring the conference system via the central unit Display V V -- P P -- Meaning and causes An undervoltage can be caused by • faulty conference units • too long system cables • too many conference units connected to a PORT socket The PORT socket is deactivated due to e.g. • no conference units connected • a short-circuit The power of the ADN CU1 central unit or ADN PS power supply is not sufficient because too many conference units are connected. Information on the power output of the ADN CU1 central unit or ADN PS power supply is not yet available. If an error icon appears (see page 59), check your conference system for the errors mentioned above. If an error is detected at startup of the central unit, first eliminate the error and then perform a manual self-test (see page 67) to check if the error still persists. If an error has only occured during operation and has already been eliminated, this is automatically detected by the central unit. Possible steps for error elimination: • Eliminate the errors separately for the ADN CU1 central unit, the ADN PS power supplies and the respective affected PORT sockets. • Calculate the maximum length of the cable string or cable ring (see page 15) and, if necessary, reduce the cable length. • Reduce the number of conference units to 15-20 max. per cable string. • If necessary, further reduce the number of conference units until there are no errors reported. Then add conference units one after the other and observe the central unit's display panel. If an error is reported, the cause of the error might be the last added conference unit, the cable used or metal parts that bridge the contacts of the plug connection.
