GRX-TVI
Phase Control to 0-10V
Interface Control
Description
The GRX-TVI provides 0-10V control and ballast
switching capabilities in one enclosure. The
interface gives GRAFIK Eye® 3000 Series Control
the ability to control 0-10V ballasts powered by
120V or 277V and provides switching relays that
can handle the in-rush current of a circuit of
ballasts. The interface gives a GRAFIK Eye 3000
Series Control the ability to both dim and switch
electronic ballasts such as Lutron's Eco-10™(TVE
models).
Mounting
• Mount the enclosure vertically on a wall. (See
Mounting Diagram below.)
• Mounting method must be able to support
weight and forces applied during installation.
Installation
NOTE: When interfacing with a GRAFIK Eye 3000
Series Control, a GRX-TVI interface is required for
each fluorescent dimming zone. (Three zone unit
with two fluorescent zones and one incandescent
zone shown as an example.)
Find a suitable location for mounting.
• Look at the System Wiring Layout (below) to
decide on the proper location for the GRX-TVI
(for indoor use only, type1 enclosure).
• The environment where the GRX-TVI is placed
must have an ambient temperature between 32-
104°F (0-40°C).

• Use the internal terminal block label to see
where to land wires. H2has a 100-120V
connection or a 220-240V connection. Use the
one corresponding to line voltage. The label
shows two separate Hot terminals (H1& H2). H1
is the Hot feed to power the lighting load. H2is
the Hot feed that powers internal circuitry of the
GRX-TVI.
Note 1: Not all terminal blocks receive a
connection.
Note 2: H2must be the same phase as
Dimmed Hot (DH).
•Applies only in the USA: Class 2, 0-10V wiring
must be separated by a barrier from the power
wiring. Enter the Class 2 wires thru the knockout
adjacent to the 0-10V terminal blocks. The
Nomex®barrier is flexible to allow access to the
terminals. The barrier must be in place when
installation is complete.
Important Installation Information
• Install in accordance with all national and local
electrical codes.
• Check for short circuited loads during new
installations before wiring the GRX-TVI.
CAUTION: Multiple feeds may enter this
enclosure. Locate and lock each feed
breaker in the OFF position before
wiring the product.
• Proper short circuit and overload protection
must be provided at the distribution panel. You
can use up to a 20A maximum circuit breaker or
equivalent with adequate short circuit breaking
capacity for your installation.

Operation
After wiring is complete, the unit can be energized
to check for proper operation.
• With the cover removed an LED will provide
visual feedback about the operation of the
system.
• When power is first applied, the LED will turn on
for 8 seconds to indicate start-up mode. The
LED will then start to flash in one of two ways to
indicate the status of the system:
Standard Operation
• The LED will flash at a rate of two pulses per
second to signify proper communication
between the GRAFIK Eye 3000 Series
Control and the GRX-TVI. (The LED will
pulse only twice during the second.)
Incorrect Operation - No Active Input
• The LED will turn on for a second then off for
a second repeatedly to indicate that there is
not an active phase control input to the GRX-
TVI. Check that the phase control dimmer is
on and connected to the GRX-TVI at the
terminal block marked DH2. Check that the
corresponding zone for the DH2terminal is
ON and the light level is not set at the
minimum output.

• When the LED indicates proper input of a phase
control signal, then output can be checked by
looking at the load and checking operation from
the GRAFIK Eye 3000 Series Control.
• Make sure the GRAFIK Eye 3000 Series
Control is set for Fluorescent Load Type.
(Refer to GRAFIK Eye 3000 Series Installer's
Guide.) If the load type is not set correctly,
proper dimming will not occur.
• For non-dimming ballasts select non-dim load
type and do not connect ballasts to 0-10V
terminals.

control (100-120V terminal
connection). 220-240V controls
use 220-240V terminal block.

Trouble Shooting Guide
Symptom Possible Solution
Cause
0-10 Volt Ballast does not dim Miswire • Verify that LED pulses once per second. If not, check
wiring from phase control unit to the GRX-TVI.
Power is OFF • Make sure the GRAFIK Eye 3000 Series Control is ON.
Miswire • Check proper polarity of 0-10V signals at terminal blocks.
Does it match what is at every ballast? A miswire at any
ballast will cause all ballasts to go to the low end.
Incorrect Control Setup • GRAFIK Eye 3000 Series Control is not configured for
fluorescent load type.
Light does not switch on Miswire • Check that the Switched Hot (SH) connection goes to the
ballasts.
Miswire • Check that the Dimmed Hot (DH) connection is actually
wired to a phase control input.
Light does not switch off Miswire • Load is not connected to Switched Hot (SH) terminal.
Miswire • Check that the Dimmed Hot (DH) connection is actually
wired to a phase control input.
LED is not illuminated No Power Input • Check that power is applied to GRX-TVI unit.
