GreenBus II Communication
(Communication Circuit, Low Voltage)
NEC Class 2
3
GreenBus II must be laid out as per ENCELIUM EXTEND LMS supplied drawing.
If changes are required, determine an optimum wiring path utilizing the supplied
prefabricated cables, based on the position of light fixtures and sensors. As the
modules obtain power via the GreenBus II, the number of modules on each chain
is limited. It is suggested to leave room for future system upgrades and to limit the
number of modules per chain to 100 units during initial installation.
One or more DALI Bridge Modules are permitted per ENCELIUM EXTEND Manager
channel with a combined maximum of 64 DALI ballasts per channel. Each
ENCELIUM EXTEND Manager can therefore control up to 512 DALI ballasts.
GreenBus II Wiring Protocol
Communication Circuit (24V
dc
, NEC Class 2)
GreenBus II
®
Wiring Protocol is a low-cost, high reliability communication means to
report information back to the ENCELIUM
®
EXTEND Light Management System
(LMS) and to obtain optimum brightness settings for light fixtures from the system –
optimized to result in minimum energy costs for any given building.
The GreenBus II wiring originates at an ENCELIUM EXTEND Manager and
propagates in a daisy-chain or “T” fashion from module to module (or other
compatible equipment).
GreenBus II uses proprietary connectors and jacks for ease of installation
only. GreenBus II is a proprietary standard. Connect to ENCELIUM EXTEND
LMS only. Do not connect to other circuits.
Most jurisdictions allow running the DALI bus as a NEC Class 1 circuit
together with line power supplying the DALI ballasts (consult applicable
local electrical and building codes).
