DESIGN GUIDE
C-Bus™ with Powerlink
®
C-Bus networks may be connected to Powerlink G3
intelligent lighting control panels utilizing the Powerlink
Device Router and the Powerlink 3000G3C controller.
Two-way communications between the C-Bus network
and the Powerlink panel allows C-Bus inputs to control
branch circuits at the Powerlink panel or override the
Powerlink schedule, and the Powerlink panel may
provide scheduled shutoff of C-Bus controlled lighting.
In the Daylighting System illustrated no shut off was
provided. To shut off lighting on a schedule, connect
the C-Bus network to Powerlink 3000G3C controller
via Powerlink Device Router. The Device Router
includes a C-Bus PCI and Power Supply, and is
connected to the Powerlink panel using a serial cable
between the RS-232 port on the PCI and the
3000G3C controller.
Daylighting Control
Daylighting control may be used to reduce articial
lighting of interior spaces when those spaces receive
adequate natural light from windows or skylights.
Daylighting controls are commonly installed in
California, where the state’s building code, Title 24,
requires the use of daylighting controls in daylit spaces.
Daylighting control may be used to save energy in
schools, ofces, warehouses, and even retail spaces.
More and more buildings, especially big box retail and
schools, are taking advantage of natural sunlight to
illuminate interior spaces. C-Bus light level sensors are
easily congured to provide daylighting control utilizing
relays for stepped dimming function or dimmer units for
continuous dimming.
