Grafik Eye GRX-WCI Installation Instructions Manual

Installation Instructions
Please Read before Installing
Overview
The GRX-WCI is for use
with GRAFIK Eye 3000
and 4000 series systems.
The GRX-WCI mounts
behind the user-supplied
switch to select or adjust
scenes in up to eight
control units. The
interface provides from
two to seven contact
closure inputs.
Specifications
• Operating voltage: PELV (Class 2: USA) low-voltage
type inputs, 12 V when used on a GRX-3000 system
and 24 V when used on a GRX-4000 system.
• If input switch is solid state, it must have an output with
an on-state saturation voltage less than 1 V
and an off-state leakage current of less than 1 mA.
Outputs must be capable of switching operating
voltage for desired life of system.
• The recommended wallbox depth is 61 mm. The
wallbox depth requirements vary with the depth of the
switch being used.
• The GRX-WCI uses one address on the communication
link.
• If there is any question as to whether a switch is
compatible with these specifications, contact the
manufacturer of the switch.
• Environment: Ambient operating temperature 0-40 °C
(32-104 °F), 0-90% humidity, non-condensing. Indoor
use only.
Caution: The GRX-WCI is not designed to work
with the line/mains voltage switches. Use with
line/mains voltage switches could result in
premature failure of the switch being used.
Caution: Install in accordance with all local and
national electric codes.

Low-Voltage PELV (Class 2: USA) Wiring
• Use low-voltage PELV (Class 2: USA) wiring to daisy-
chain the GRX-WCI to GRX-3000/4000 control units
and other components.
• Make connections inside the wallbox, switchbox, or
junction box with a maximum wire length of 2.5 m
from the link to the GRX-WCI.
When used with GRX-3000 control units:
• Use two 1.0 mm (#18 AWG) conductors for common
2
(terminal 1) and 12 V
terminal 2 connection correctly; refer to the GRX-3000
Installation Guide.
• Use one shielded, twisted pair 1.0 mm
wires for data link (terminals 3 and 4).
When used with GRX-4000 control units:
• Use two 2.5 mm (#12 AWG) conductors for common
2
(terminal 1) and 24 V
into terminals; see next page for connection details.
• Use one shielded, twisted pair 1.0 mm
wires for data link (terminals 3 and 4).
• Connect drain/shield as shown on next page.
-Do not connect ground/earth to GRX-WCI.
-Connect the bare drain wires and cut off the outside
shield.
