IMPORTANT! GRAFIK Eye lighting controls must be installed by a qualified electrician in accordance with all applicable
regulations. Improper wiring can result in personal injury or damage to GRAFIK Eye lighting controls or other equipment.
Always turn off circuit breaker/MCB or remove main fuse from power line before doing any work. To avoid overheating and
possible damage to equipment, do not install dimming devices to dim receptacles, motor-operated appliances, or
fluorescent lighting not equipped with Lutron Hi-lume®, Eco-10™, or Tu-Wire™Electronic Dimming Ballasts. In dimmed
magnetic low-voltage circuits, you can prevent transformer overheating and failure by avoiding excessively high current
flow: Do not operate GRAFIK Eye lighting controls with any lamps removed or burned out; Replace any burned out lamps
immediately; Use only transformers that incorporate thermal protection or fused primary windings. This lighting control is
designed for residential and commercial use. GRAFIK Eye Controls are designed for indoor use only.

STEP 1: Installing Control Units
This section shows how to install Control Units and make sure they are properly operating all connected loads.
CAUTION!
First test loads for short circuits.
1. Turn power OFF at the breaker/MCB panel or fuse box.
2. Connect standard light switch between live lead and the load wire to test circuit.
3. Turn power on and check for short or open circuits: If load does not operate, circuit is open. If the
breaker/MCB trips (fuse blows or opens), circuit is shorted. Correct short or open circuits and test
again.
Load Types
The Control Units can control incandescent, halogen (tungsten), magnetic low-voltage, and neon/cold cathode load types. Electronic low-
voltage and fluorescent load types can be controlled with an appropriate interface.
■Not all zones need to be connected; however, connected zones must have a load of at least 25W (40W for AU and CE models).
■No zone may be loaded with more than 800 W (1200 for AU models).
■Unit must not carry more than 16A of total lighting load (10A for CE models).
■All Electronic Low-Voltage (ELV) lighting used with the Electronic Low-Voltage Interface must be rated for reverse phase-control
dimming. Before installing an ELV light source, verify with the manufacturer that their transformer can be dimmed. When dimming, an
Electronic Low-Voltage Interface MUST be used with the Series Control Unit.
Installation instructions. First, turn power off.
Preparation
1. Mount Wallbox. Use standard U.S. wallbox, 3 1/2 in. (87 mm) deep is strongly
recommended, 2 3/4 in. (68 mm) deep minimum. Always allow at least 4 1/2 in. (110 mm)
clearance above and below the faceplate to ensure proper heat dissipation.
2. Pull Wires. Use the rearmost knockouts when pulling wires into the wallbox. This will
provide the most clearance when mounting the Control Unit.
3. Remove Cover. Remove the Control Unit’s cover and hinged faceplate by pulling outward at
each corner.

Line Voltage/Mains Wiring
IMPORTANT WIRING NOTES!
■Use properly certified cable for all line voltage/mains cables and
Class 2/PELV cables.
■In Europe, acceptable types of cable include HAR certified cable
with insulated cores enclosed in a sheath. This cable must bear the
appropriate certification mark pertaining to national wiring rules for
fixed installations. If certified cable with insulated cores enclosed in
a sheath is used for the Power cables, the Class 2/PELV wiring can
be any of the specified cables in Appendix A: More about
Class 2/PELV Wiring.
■Proper short-circuit and overload protection must be provided at
the distribution panel. You can use up to a 20A (16A for AU, and
10A for CE models) maximum circuit breaker/MCB or equivalent
(tripping curve C according to IEC60898/EN60898 is
recommended) with adequate short-circuit breaking capacity for
your installation.
■Install in accordance with all local and national electrical codes.
■CAUTION! Do not connect line voltage/mains cable to Class 2/
PELV terminals.
■Earth/Ground terminal connection must be made as shown in
wiring diagrams.
■Do not mix different load types on the same zone!
■Fluorescent and electronic low voltage loads require
interfaces. Zone loads that exceed 800W/VA (1200W/VA for
AU models) and total unit loads that exceed the unit capacity
require power boosters. Refer to Appendices C, D, E, and F.
Wire the Control Unit (see Page 16)
1. Strip 1/2 in. (12 mm) insulation from all wires in wallbox and
connect them to appropriate terminals on the back of the
Control Units. The recommended installation torque is 9.0
in.●lbs. (1.0 N●m) for line voltage connections and 10 in.●lbs.
(1.3 N●m) for the earth/ground connection. Each power
terminal can accept up to two #12 AWG (2.5 mm2) wires. (Does
not apply to Class 2/PELV terminal block.)

1. Set all zones connected to HP 2•4•6 Dimming Modules as shown—
no matter what load type they are (including non-dim or switching). The
HP 2•4•6 can be used to switch non-capacitive ballasts. To fine-tune
the dimming of these “HP-powered” zones, you must adjust high- and
low-end trim on the HP 2•4•6 Dimming Module as described in the
Instruction Sheet supplied with the unit. Do NOT use HP 2•4•6
Dimming Modules with generator-supplied line/mains voltage.
2. All electronic low-voltage (ELV) lighting used with the Electronic Low-
Voltage Interface (ELVI) must be rated for reverse phase control
dimming. Before installing an ELV light source, verify with the
manufacturer that their transformer can be dimmed. When dimming, an
ELVI MUST be used with the 3000 Series Control Unit.
3. Any zones set for Lutron Hi-lume or Eco-10 fluorescent lighting must have
GRX-FDBI or GRX-TVI Fluorescent Interfaces. Consult Lutron for more
information.
4. Please note that the Tu-Wire Compact Fluorescent, unlike other fluorescent load
types,does not require an FDBI interface. This load type is not available in
GRX-CE models.
5.Use non-dim for any lights to be switched on and off only—not dimmed (unless
using HP Dimming Module).
■Fluorescent non-dim loads with electronic or magnetic ballasts must: use a
GRX-TVI Interface and be set for non-dim mode, or use an HP 2•4•6 and
be set for HP 2•4•6 loads.
What is a scene?
* The S and M indicators under the FADE window show
whether FADE is “M”inutes or “S”econds. To set FADE in
minutes, you press FADE 5to scroll through 1—59
seconds . . . the M lights. FADE is now expressed in minutes.
To get back to seconds, press FADE 6until the window
shows “S”econds.
Note: Control Unit must be in mode. See page 9 for more
information regarding Save Options.
To set up scenes 1 through 4:
1. Select a scene. Press the Scene button for the scene you want to
adjust. (First button for Scene 1, second button for Scene 2, and so
on.) Note that the last button is the “Off” Scene. You do not set
intensities for this button.
2. Set each zone’s light levels. Press ZONE 5and 5to adjust
each ZONE to the right visual intensity for this scene. (ZONE LEDs
show intensity bargraph-style. Each LED represents ~ 15% intensity
change. In this example, ZONE 6 is set to 60%.) To program scenes 5
through 16, or for more precise zone intensity adjustment with a
GRAFIK Eye 3500 Control Unit, refer to page 8.
3. Set scene’s FADE-in time. Press FADE 5and 5to make
FADE-in time anything from 0—59 seconds or 1—60 minutes*. (A
scene’s FADE-in time is how long it takes light intensities to adjust to
their new levels when the scene is selected.)
Repeat this process to set up each of the remaining scenes. Note that you
can also set up a “FADE-to-off” time. Press the OFF button and adjust
FADE as desired.
Scenes are the preset light levels and fade times stored in the Control
Unit. To create a scene, set the appropriate intensity for each ZONE. To
recall a scene, simply press one of the buttons. The first button calls up
Scene 1; the second, Scene 2; and so on. The last button turns lights Off.

How to adjust light levels temporarily
How to set low-end trim—OPTIONAL
If necessary, adjust the low-end trim to achieve uniform low-
intensity dimming and to eliminate flicker (especially with neon/
cold-cathode and fluorescent loads).
1. Enter setup mode. Press and hold Scene 1 and OFF
buttons for about 3 seconds, until scene LEDs start cycling.
2. Select LE (for low end) by pressing FADE 6once. All
zones go to their lowest possible dim levels and only their
bottom LED is lit*.
3. Adjust zone’s lights for low-end trim. Use ZONE 6
and 5to dim the zone’s lights as much as possible without
causing flicker. This setting becomes the “optimum lowest
level” to which the zone will dim before going off. Repeat this
process for any other zones that require low-end trim.
4. Exit setup mode. Press and hold Scene 1 and OFF buttons
until scene LEDs stop cycling.
Note: The ZONE LED bargraph does not change while you
make low-end trim adjustments. The bargraph remains
set to its lowest level in this mode.
Advanced Scene Programming Options—OPTIONAL
Control Unit must be in either or mode. See page 9 for
more information regarding Save Options.
To adjust an entire scene:
Press the appropriate scene button.
Press MASTER 5or 6to raise or lower the intensity of all
zones.
To adjust a zone:
If the TEMPORARY LED is not already lit, press the
TEMPORARY ZONES button. The TEMPORARY LED above the
TEMPORARY ZONES button will light.
Press ZONE 5or 6to adjust any zone’s intensity.
Note: These adjustments are temporary and remain only until a
new scene selection occurs—the GRAFIK Eye Control
Unit does not store them as permanent scene settings.

STEP 4: Setting Up System Communications
This section shows how to set up communications between
Wallstations and the Control Units they should operate.
Do not set up communications . . .
Why do you set up communications?
Assign each GRAFIK Eye Control Unit in your project a unique
system address (AI through A8).
To assign an address:
1. Enter setup mode. Press and hold Scene 1 and OFF
buttons about 3 seconds, until scene LEDs cycle.
2. Select A- (the address display). Press FADE 5once, A-
appears in the FADE window.
3. Assign a unique address. Press MASTER 5once, the
next “free” (unassigned) address automatically appears in
the FADE window. This will be the Control Unit’s address. (If
you are working on the first Control Unit in the project, AI
will appear.)
4. Exit setup mode. Press and hold Scene 1 and OFF
buttons about 3 seconds, until the LEDs stop cycling.
5. Repeat steps 1 through 4 for each GRAFIK Eye Control
Unit.
■If you have only one Control Unit and . . .
— you have up to three of the following Wallstations: NTGRX-4S,
-4B, -4S-IR, -4S-DW, or EGRX-4S, -
4S-IR, in any combination.
Close this manual and relax — your project will work as specified
without any further wiring or setup!
Do set up communications . . .
This diagram shows how Wallstations “talk” to Control Units
in a typical residential project:
■The NTGRX-2B-SL in the hallway turns lights on and off
in the master bedroom and great room. To do this, the
-2B-SL “talks” to the Control Units in both of these
rooms.
■The NTGRX-4S Scene Selection Control in the master
bedroom allows you to choose four different lighting
scenes. To do this, the -4S “talks” to the master bedroom’s
Control Unit (but not to the Great Room’s Control Unit).
First check Class 2/PELV wiring.
Before you set up communications, make sure your Class 2/PELV system
interconnections are working.
■Select Scene 1 (press the top button) on one of the
Control Units.
■Is Scene 1 selected on all other Control Units and NTGRX-4S
controls?
YES: Class 2/PELV wiring is OK. Proceed.
NO: Class 2/PELV wiring has a miswire. Check for loose
connections, shorted or crossed links. Refer to Appendix A
for details on Class 2/PELV wiring.

Set up a Wallstation to “talk” to a “listening” Control Unit
In order for Wallstation to communicate with a Control Unit, each Wallstation must be individually configured to “talk.”
The communication link is now established. The Control Unit will “listen” when the user presses a button on the Wallstation. You can proceed
to the next Wallstation and set up its communications.
For more specific, step-by-step instructions about setting up communications for each type of GRAFIK Eye Wallstation, please refer to the
instructions included with each Wallstation.
Set up 2-way communication between 2 Control Units
This page explains how to use 2-way
communications to set up lighting
effects for more than six zones (the
maximum number of zones any
one
3000 Series Control Unit can operate).
When you set up two-way
communications between Control
Units, selecting a scene at any one of
these Units automatically activates the
same scene in the others. By linking
eight 6-Zone Control Units, you can
create scenes that control the intensity
of up to 48 zones. This “large-zone”
capability is ideal for large spaces
with dramatic lighting that changes
frequently (e.g., churches).
For example: 16-Zone Control

Linked by two-way communications, these Control Units act like a 16-Zone Control Unit. Note that
you must set up communications
both ways among all Control Units:
■A1 “talks” to A2 and A3 –– and “listens” to them as well.
■A2 “talks” and “listens” to A1 and A3.
■A3 “talks” and “listens” to A1 and A2.
Make sure you have addressed the Control Units (as described on page 10) before setting up two-
way communications.
Set up communications
in one direction . . .
. . . then the other.
1. Put A1 in setup mode. Press and hold Scene 1 and
OFF buttons for about 3 seconds, until LEDs cycle.
2. Identify the Control Units to “listen” (A2 and up
to 6 others). Press and hold the Scene 1 button for
about 3 seconds until LEDs flash in unison, showing
that these Control Unit(s) are “listening” to A1. (To
make a “listening” Control Unit not listen to A1: Put
A1 in setup mode, then press the “listening” Control
Unit’s OFF button until the LEDs stop flashing.)
3. Take A1 out of setup mode. Press and hold Scene
1 and OFF buttons for about 3 seconds, until LEDs on
A1, and all other linked Control Unit(s), stop cycling.
You have set up communications in one direction
between A1 and all “listening” Control Units.
4. To complete the two-way communication, reverse the process described above: Put A2 in setup
mode; then make A1 (and any other Control Units) “listen”; then take A2 out of setup mode.

Appendix A: More about Class 2/PELV Wiring
This appendix explains the Class 2/PELV wiring used to carry communications between GRAFIK
Eye Control Units and Wallstations.
Lutron requires that you connect (daisy-chain) all GRAFIK Eye 3000 Series Control Units and
Wallstations with two twisted pair for operation. If shielded wire is used, the drain wires must be
connected to each other or to Terminal D, if present. Drain wires should not be connected to
Earth/Ground.
■One pair is for the low-voltage power wiring that enables each GRAFIK Eye Control Unit to
supply power to up to three Wallstations. Connect this twisted pair to terminals 1
(COMMON) and 2 (12VDC). Terminate the 12VDC power to ensure that each Control Unit
powers
no more than three Wallstations.
■The second pair is for a data link (up to 2000 ft. or 450 m long) that enables Wallstations to
communicate with GRAFIK Eye Control Units. Connect this twisted pair to terminals 3 (MUX)
and 4 (MUX) of every Control Unit and Wallstation.
Each twisted pair in the Class 2/PELV wiring link should consist of two #18 AWG (1.0 mm2)
stranded conductors.
■Lutron offers a one-cable (non-plenum), low-voltage solution. Please ask for
P/N GRX-CBL-346S.
Recommended unshielded cables:
■For non-plenum installations, use (2) Belden 9470, (1) Belden 9156, or (2) Liberty 181P/
2C-EX-GRN, or equivalent.
■For plenum installations, use (2) Belden 82740, or equivalent.
Wallstation circuits are classified as Class 2 circuits (U.S.A) and PELV circuits (IEC). Unless otherwise specified, the voltages do not exceed 24VAC or 15VDC. As
Class 2 circuits, they comply with the requirements of NFPA 70, National Electrical Code (NEC). As PELV circuits, they comply with the requirements of IEC 60364-4-
41, VDE 0100 Part 410, BS7671:1992 and other equivalent standards. When installing and wiring to these Wallstations, follow all applicable national and/or local
wiring regulations. External circuits connected to input, output, RS232, DMX512, and other communication terminals of Wallstations, must be supplied from a Listed
Class 2 source or comply with the requirements for PELV circuits as applicable in your country.
The GRAFIK Eye 3000 Series Control Unit Class 2/PELV circuit is 12VDC.

In countries that abide by the IEC regulations, PELV is commonly referred to as Protective Extra-Low Voltage. A PELV circuit is an earthed
circuit in which the voltage cannot exceed 50VAC or 120V ripple-free DC. The power source must be supplied by a safety isolating transformer
or equivalent.
IMPORTANT WIRING NOTE!
Proper separation is required between the Line Voltage/Mains cables and PELV cables. Use certified cable for all Line Voltage/Mains cables
and PELV cables. Cable bearing HAR or national certification marks are acceptable, provided it covers all applicable wiring regulations for
fixed installations. See Important Wiring Note on page 3.
Each Control Unit can power up to three Wallstations. If you need to power more than three Wallstations from one Control Unit, install an
external 12VDC power supply as described later in this section.
Maximum of 1000 ft. (300 m) between the GRAFIK Eye Control Unit and the
third Wallstation. For longer distances, use an external Class 2/PELV rated
12VDC power supply (see page 13).
IMPORTANT WIRING NOTES!
1. Daisy-chain the terminal 1, terminal 2, terminal 3, and terminal 4 connections to all Control Units and Wallstations. The Control Unit
has
its own power supply.
2. Each Control Unit can power up to three Wallstations. If you need to power more than three Wallstations from one Control Unit, install an
external 12VDC power supply as described later in this section.
3. Lutron recommends that all connections be made in the unit wallbox. Remote connection must be in a switchbox or junction box with a
maximum wire length of 8 ft. (2.5m) from the link to the connected unit.
Note: Do not allow Class 2/PELV wires to contact line/mains wires. Refer to Class 2/PELV wiring on page 4.

IMPORTANT WIRING NOTES!
1. Daisy-chain the terminal 1, terminal 3, and terminal 4 connections to all Control Units and Wallstations. Each Control Unit has its own
power supply. Terminate the terminal 2 connection (12VDC power) so that:
■Each Control Unit supplies power to a maximum of three Wallstations.
■Each Wallstation receives power from only one Control Unit.
2. Lutron recommends that all connections be made in the Control Unit’s wallbox. Remote connection must be in a switchbox or junction
box with a maximum wire length of 8 ft. (2.5 m) from the link to the connected unit.
Note: Do not allow Class 2/PELV wires to contact line/mains wires. Refer to Class 2/PELV wiring on page 2.
Installing an external power supply
Install an external Class 2/PELV rated 12VDC power supply as shown below. This power must be Class 2/PELV rated and be a regulated
supply rated for at least 50 mA per Wallstation on the link. It can supply power to up to 16 Wallstations, enabling you to use up to 16
Wallstations with one Control Unit.
Use an external power supply if you need to power more than 3 Wallstations from a single Control Unit or if your wire lengths exceed
maximums. Power supplies do not boost data line signals. The distance limitation for the data line is 2000 ft. (450 m).
Make sure you review the manufacturer’s instructions before installing.
Lutron offers a 12VDC transformer for 120V applications. Please ask for P/N GRX-12VDC.
IMPORTANT WIRING NOTES!
1. Connect the +12VDC wire from the power supply to the terminal 2 connection on all Wallstations. Do not connect this wire to any Control
Units on the link. Be sure that the terminal 1 connection is made to all Wallstations and Control Units.
2. Lutron recommends these maximum distances from the external 12VDC power supply to the sixteenth Wallstation:
■#18 AWG (1.0 mm2) wire: 300 ft. (90 m). ■#12 AWG (2.5 mm2) wire: 1000 ft. (300 m).
Note that the allowable maximum distance depends on the number of Wallstations in the system. Please see Application Note W14 or consult
the Lutron Technical Assistance Hotline for more detailed information.

Wallbox Mounting
Spacing of the GRAFIK Eye 3000 Series Control Unit
When mounting multiple GRAFIK Eye 3000 Series Control Units near each other, the
following spacing and ventilation guidelines are required for proper operation.
1. All GRAFIK Eye 3000 Series Control Units MUST be mounted in a standard
U.S. Wallbox. These are available from Lutron.
■For two-zone Control Units, Power Boosters, Fluorescent Interfaces, and
Electronic Low-Voltage Interfaces, use two P/N 241-519 single-gang
wallboxes.
■For three-zone Control Units, use three P/N 241-519 single-gang
wallboxes.
■For four-zone (or larger) Control Units, use one P/N 241-400 four-gang
wallbox.
Note: All GRX-CE Control Units mount in one P/N 241-400 four-gang
wallbox.
2. All GRAFIK Eye 3000 Series Control Units, Power Boosters, Fluorescent Interfaces, and Electronic Low-Voltage Interfaces MUST have
4 1/2 in. (11 cm) of space above and below the faceplate to dissipate the heat caused by normal operation.
Panel Mounting
■The enclosure must be in accordance with all local and national electrical
codes.
■Lutron does not recommend using a door to enclose the front of a panel,
since this restricts airflow to the GRAFIK Eye 3000 Series Control Units
and Interface Devices.
■If mounting multiple GRAFIK Eye 3000 Series Control Units or Interface
Devices in an enclosure:
1. Ambient temperature within an enclosure MUST remain between
32°—104°F (0°—40°C).
2. If not mounting in a metal enclosure, all units MUST be mounted in a
wallbox. Refer to Wallbox Mounting above.
■To improve heat dissipation of Interface Units, (i.e., NGRX-PB, GRX-ELVI,
etc.), remove the faceplate from the unit.
IMPORTANT NOTE:
GRAFIK Eye 3000 Series Control Units and Interface Devices, such as NGRX-
PB, dissipate heat when operating.
Obstructing these units can cause malfunction to both the Control Unit and the Interface Device if ambient temperature does not remain
between 32°—104°F (0°—40°C).

Programming Interface
Appendix F: Infrared Transmitters
Infrared Transmitters
GRAFIK Eye Control Units are equipped with an Infrared Receiver. This
allows control of the Control Unit with the optional Handheld Infrared
Wireless Remote Control Transmitters. The Infrared Transmitters control 4
(or 8) scenes plus master raise/lower and Off. With this you can recall
scenes or fine-tune light levels.
Infrared Interference
All GRAFIK Eye 3000 Series Control Units are equipped with an IR Receiver for use with Lutron GRX-IT and GRX-8IT handheld remote
controls. The IR frequency for all Control Units is 40.000 KHz. Any other device continuously operating in the frequency range from 30 KHz to
50 KHz may cause either no response or unwanted scene changes on the Control Unit. Fluorescent ballasts are a known cause of IR
interference to the Control Unit and Wallstations. Lutron dimming ballasts have been thoroughly tested to ensure that there is no IR
interference with any GRAFIK Eye product. However, other manufacturer's ballasts may cause interference. It is the responsibility of the
contractor to determine the operating frequency of the ballasts used on the project. Lutron takes no responsibility for ballast interference to the
GRAFIK Eye system.
Appendix G: Troubleshooting
If the GRAFIK Eye lighting controls in your project aren’t working as
specified . . .
■Review carefully the GRAFIK Eye submittal documentation
prepared for your project — especially the project’s One-Line
Diagram, which gives an overview of the wiring and shows how
all GRAFIK Eye equipment connects. A sample One-Line Diagram
is shown at right. The GRAFIK Eye Designer™ software, which
produces such one-line diagrams, is available from Lutron.
■Consult the chart below to identify and correct the problem.
■If necessary, call Lutron.
