2Link
™- an option feature on a Circuit Selector that allows a circuit within
a Lighting Control Panel, to be assigned to any zone on either Control
Link A or Control Link B. The choice of Link Hierarchy determines
which Link's intensity level is sent to a specific circuit.
Accessory Control
- former term for a Wallstation and Control Interface.
These were separated to avoid confusion.
Addressing
- a way for the controls on a link to identify each other.
Wallstations are addressed, using switches 1 through 4 on the back of
each control. Each control needs a unique address. GRX-4000 Series
Control Units are addressed while in Set-Up Mode from the front panel’s
buttons.
Circuit Selector
- the interface between the Control Link(s) and the
digital dimmers that reside in a GP panel. The Circuit Selector houses
all Circuit Values including Load Type, Control and Zone assigned, and
Low End and High End light levels. 2Link is available as an option or
upgrade.
Control Interface
- GRAFIK EYE control wired to a GRX-4000 (or GRX-
3000) Series Control Unit to select scenes, raise and lower specific
zones or other functions on an attached Control Unit. An external
closure or a computer typically activates these functions.
Control Link
- the daisy-chained link of controls wired to the Circuit
selector. A Control Link can be a) GRX-3000/4000, b) G6000, or c)
DMX-512.
Dimmed Hot (DH)
- a variable output from each circuit. This output must
be used for all Non-Dim Load Types to ensure full lifetime of the
dimmer’s relay closure. The output limits and characteristics are set by
the Load Type.
Fade
- a gradual change in light intensity in a room or space.
Fade Time
- selected time interval to change from one scene to another. A
GRX-4000 (and GRX-3000) Series Control Unit has a customer-
adjustable fade time that ranges from 0-59 seconds and 1 to 60
minutes.
GP Panel
- GRAFIK Eye Lighting Control Panel - a panel (rack) of digital
dimmers (circuits) which can be assigned to Dim or Non-Dim multiple
load sources.
Link Hierarchy
- a value that must be set when using the 2Link option on
the Circuit Selector. This value determines when either Link A or Link B
controls the output of any circuit within the Control Panel.

LED (Light Emitting Diode)
- an illuminated indicator to help in setting
up and diagnosing GP Panel and GRX-4000 Series Control Unit’s
functions.
Load Type
- a value in the Circuit Selector that defines the performance of
the circuit to optimally control loads such as: Incandescent, Hi-lume
FDB or Eco-10 Dimmable Fluorescent, Neon, Non-Dim, Electronic Low
Voltage.
Low End -
the light level when a circuit output is at its lowest intensity
(just above OFF). The Low End can be trimmed to a brighter or dimmer
level. Low End is usually set for aesthetics.
Non-Dim Load -
a source that is not to be dimmed. Load Circuit wiring is
to be connected to the Dimmed Hot (DH) terminal and Load Type for
that circuit is to be set to a Non-Dim Load Type only.
RTISS
TM
- Real Time Illumination Stability System used to filter noise out
of the power feed to each digital dimmer, resulting in a more stable
output.
Scene - (or Preset
) - Predetermined light intensity for one or more
lights, creating a lighting effect that can be recalled by pressing a single
button. The GRX-4000 Series Control Unit has Scene 1-4 and OFF
accessible on the front of the control. Some Wallstations and Interface
Controls can be Set-Up to access Scenes 5-16.
SSA
- Single Scene Activator (model # NTGRX-1S) alternately toggles the
GRX-4000 (or GRX-3000) Series Control Unit, to which it is wired,
between Scene 1 and OFF. The SSA is not counted as a Wallstation.
Multiple SSA controls can be wired in parallel controlling the same
GRX-4000 Series Control Unit. SSA controls do not work with 2-Zone
Control Units.
Switched Hot (SH)
- an unprotected relay closure from each dimmer. This
output is used for Hi-lume FDB or Eco-10 Fluorescent only.
Wallstation
- GRAFIK EYE control wired to a GRX-4000 (or GRX-3000)
Series Control Unit to select scenes, raise and lower specific zones or
other functions on an attached Control Unit. Buttons typically activate
these functions.
Zone
- a fixture or a group of fixtures controlled simultaneously. The GRX-
4000 Series Control Unit controls multiple zones (e.g., a GRX-4008 can
control 8 zones). Each zone can be assigned to one or more Circuits in
a GP Panel. Each zone should only control one Load Type.
Zone Capture™
a method of Assigning a Control and Zone to a circuit
without knowing Control Addresses. See ‘Circuit Selector Functions’ in
the Reference Section
.
