.cDALI scene controllers: DALI-SC & SC-ADALI scene controllers: DALI-SC & SC-ADescriptionDALI-SC is a module that enables scene selection commands for up to four scenes (A, B, C, D) to be sent to the DALIcircuit. Any standard momentary switch can be connected to the module. Its compact design means that DALI-SC canbe installed together with the standard momentary switches in a flush-mounted box, so set-up of the DALI circuit canbe decentralised.The scenes are set on a rotary switch on the module.The DALI SC module is multi-master-compatible so several control modules can be used in a DALI circuit.DALI-SC-A is similar to DALI-SC. The only difference is that the programming mode is not activated in DALI-SC-A.This prevents the DALI units from being reprogrammed unintentionally via the momentary switches.ConnectionThe DALI-SC scene module is connected directly to the DALI circuit and does not need a separate power supply. It ispowered via the DALI circuit (current draw = 6 mA). It can be connected to the DALI circuit with either polarity.Figure: DALI-SC switch connection½ CAUTION!The connection leads between the momentary switches and the DALI-SC must not be lengthened. The DALI circuitis not SELV. This means that the switches and cabling must be suitable for mains voltage.DALI Manual | 08-2013 | en31 / 93
