Radia Lighting Control System
Integrated Dimmer Module
- A Radia Lighting device that contains both a six-channel master
controller and dimmers on the same package. They will have a PROlink address and can be on
AXlink. The RDD-DM4/ series and the RDD-DM6/ series are integrated dimmer modules, and
they all take up two module spaces.
Level Time
- A Radia Lighting default parameter. Level time is the time it takes for a dimmer to
reach its assigned level after receiving a level command.
Line
- The wire or circuit that supplies power to a dimmer or electrical device. The line wire often
comes from an electrical circuit breaker panel.
Load
- The particular device or resistance of a device to the power being delivered. Also the total
amount of devices connected to the output of a dimmer or switch. The load wire connects from the
dimmer to the lamps. Lights are common loads along with motors and other power equipment.
Master Controller
- A Radia Lighting device capable of six channels of control, an AXlink
connection, PROlink connection, and a dry closure connection. Same as Controller.
Magnetic Transformer
- A coil-core transformer that dims a light when the primary voltage from
the transformer is reduced, causing the secondary output of the transformer to reduce its voltage
through magnetic coupling. Incandescent dimmers can be used to control magnetic transformers.
Metal Halide
- A HID lamp that uses radiation of metal halides in combination with metallic
vapors like mercury. Not normally a dimmable lamp, and requires long start up times.
Module
- A Radia Lighting dimmer or switch designed for installation in a Radia Lighting
enclosure. Most modules are on a standard 2.75" x 10" enclosure plate or heatsink; some modules
require two standard spaces.
Neon
- A light source made from high voltage excitation of neon gas enclosed in a glass tube. Neon
is a type of lamp that uses a step-up transformer to operate the lamp. Neon transformers can be
dimmed.
Pack
- A Radia Lighting Central Controller consisting of six channels of control on the PROlink
control bus. Pack settings of 1 through 10 allow for 10 six-channel packs for a total of 60 channels
of control on one PROlink bus.
Peak Switch
- A switch that opens or closes at the height of the AC cycle, as opposed to the zero-
cross point of the AC cycle.
Phase Dependent
- A dimmer module must have its supply voltage on the same phase (A, B, or C)
as the electricity supplied to the controller. Only dimmer modules are phase-dependent.
Port (Control Port)
- A four-pin connector used to connect a Radia Lighting module to a
controller. There is a maximum of six ports on the Central Controller.
Power Consumption Rating
- An amount of energy used by a device to perform its function at
maximum load. Radia Lighting devices have power consumption ratings expressed in milliamps
(mA). Radia Lighting controllers provide this power to operate the modules and can also get more
power from external power supplies.
Power Rating
- Ratings expressing the maximum load capacity of a module, dimmer, or switch.
Radia Lighting power ratings are based on UL testing and approvals.
Preset
- A preset is a stored scene. Presets can consist of a single dimmer or any combination of
dimmers as a group of stored values. Radia Lighting presets allow a dimmer or any combination of
dimmers to be excluded from a preset.
