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 Liaison

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 mm 2 ) 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 .
