The following guides provide examples of typical wiring diagrams and requirements for the four main types of control
systems:
s 3WITCH DIM BALLAST
– using local push to make switches
s
6 ANALOGUE DIMMABLE BALLAST
– Incorporating a dimmer circuit and controlled by local potentiometer
s $IGITAL 3ERIAL )NTERFACE $3)
– Requiring a control loop to send digital control signals and local switch plates or
remote control device to control (usually requires programming)
s $IGITAL !DDRESSABLE ,IGHTING )NTERFACE $!,)
– incorporating dimmer and local intelligence, requires a DALI bus
and control devices or by sophisticated management systems
