GRAFIK Eye®3000 Series Control Unit Installer’s Guide 3
Factory Presets
Lutron ships each control unit with the following factory presets (A- mode). In this mode,
control units and lighting wallstations communicate with no additional programming.
Accessories
Depending on the size and requirements of the lighting system, control units can be configured
to work with a variety of optional accessories, including:
• Low-voltage wallstations. Wallstations, shade controllers, infrared (IR) sensors and receivers,
and door-jamb controls.
• Control interfaces. Contact closure devices, RS232 and Ethernet digital communications.
astronomic timeclock, and programming interface for GRAFIK Eye LiaisonTM software.
• Load interfaces. Required for any loads exceeding the maximum zone capacity (see page 2),
as well as Lutron 3-wire fluorescent dimming ballasts, electronic low-voltage lighting, and 277
V loads.

System Communications and Capacities
PELV (Class 2: USA) cable can be used to connect GRAFIK Eye 3000 control units,
wallstations, and other accessories. You can link up to 8 control units to control up to 48
zones, and add up to 16 wallstations and 8 shade controllers (SG-SVC) for a total of 32 control
points. Note that wallstations control scenes (which can include light and shade settings);
shade controllers control only shades.
PELV (Class 2: USA) Cables
If your lighting system uses wallstations and/or multiple control units, PELV (Class 2: USA)
wiring is needed to supply power and carry communications between the control units and the
wallstations. PELV (Class 2: USA) wiring is also needed to connect other accessories.
Use properly certified PELV (Class 2: USA) cable. Each twisted pair in the PELV (Class 2: USA)
wiring link should consist of two #18 AWG (1.0 mm2 ) stranded conductors.
• One pair is for the low-voltage power wiring.
• The second pair is for a data link (up to 2000 ft/610 m long).
Note: Lutron offers a one-cable, low-voltage solution: P/N GRX-CBL-346S (non-plenum) or
GRX-PCBL-346S (plenum). Check availability and applicable electrical codes in your area.
In countries that abide by the IEC regulations, PELV is commonly referred to as Protective Extra-
Low Voltage. A PELV circuit is a grounded circuit in which the voltage cannot exceed 50 V or 120 V
ripple-free. The power source must be supplied by a safety isolating transformer or equivalent.
Recommended unshielded cables include:
• 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.
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 PELV wiring can be any of the cables listed above.
