LUTRON GRX-TVI Dimmer Interface
Description
The GRX-TVI provides 0-10V control and ballast switching capabilities in one enclosure. The GRX-TVI gives GRAFIK Eye 3000 Series Control Units the ability to control any 0-10V ballasts powered by 100V-277V (ballast must provide 0-10V sourcing of current) and provides switching relays that can handle the inrush current for a circuit of ballasts. The GRX-TVI gives a GRAFIK Eye 3000 Series Control Unit the ability to both dim and switch electronic ballasts, such as Lutron’s Eco-10™ (TVE models). The GRX-TVI can also be used to switch any of the load types listed below.

- TERMINALS Two #12-20AWG (0.5-2.5 mm2) conductors per terminal.
- MOUNTING NEMA Type 1 enclosure, indoor use only.
- ENVIRONMENTAL 32—104 °F (0—40 °C).
- WEIGHT 4.25 lb. (2kg)
Mounting
Find a suitable location for the mounting.
- Decide on the proper location for the GRX-TVI (NEMA Type 1 enclosure, indoor use only). See System Wiring Layout below.
- The environment where the GRX-TVI is placed must have an ambient temperature range of 32—104 °F (0—40 °C).
- Mount the enclosure vertically on a wall (screws not provided). See Mounting Diagram below.
- The mounting method must be able to support the weight and forces applied during installation.
- Internal relays will click while in operation — mount where audible noise is acceptable.
System Wiring Layout
Note: When using a Control Unit, a GRX-TVI is required for each 0-10V fluorescent zone. (A 3-zone Control Unit with two fluorescent zones and one incandescent zone is shown as an example.)

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 circuit breaker/MCB in the OFF position before wiring the Interface. -
Proper short circuit and overload protection must be provided at the distribution panel. You can use up to a 20A (16A for CE) maximum circuit breaker/MCB or equivalent (tripping curve C according to IEC 898/EN60898 is recommended) with adequate short circuit breaking capacity for your installation.
-
Terminal blocks are rated for two #12-22 AWG (0.5-2.5 mm2) wires per terminal.
-
Strip 3/8 in. (10 mm) of insulation from wires.
-
Wiring Diagram A shows a GRX-TVI wired from one distribution panel. If the power requirement of the complete system is less than an MCB/circuit breaker rating, one feed can be jumpered inside the enclosure (as shown).
-
Wiring Diagram B shows a GRX-TVI wired from two separate distribution panels that may be different phases or voltages.
-
Use the internal terminal block label to see where to land wires.
- The label shows two separate Hot/Live terminals (L1/H1 & L2/H2).
L1/H1 is the Hot/Live feed to power the lighting load.
L2/H2 is the Hot/Live feed that powers internal circuitry of the GRX-TVI.
L2/H2 has a 100-127V connection and a 220-240V connection – use only the one corresponding to line voltage for your application.
Note 1: Not all terminal blocks receive a connection.
Note 2: The power feed to the Control Unit and L2/H2 of the GRX-TVI must be the same phase! Use only if your line/mains voltage is Class 2/PELV, 0-10V wiring from a ballast to the GRX-TVI- 120-127V. CE must be separated from the power wiring. Enter the
Class 2/PELV wires through the knockout adjacent to the 0-10V terminal blocks. The Nomex® barrier ensures separation and is flexible to allow access to the terminals. The barrier must be in place when installation is complete.
- The label shows two separate Hot/Live terminals (L1/H1 & L2/H2).
GRX-TVI Internal Terminal Block Label Definitions Use only one input according to Input Voltage:
Use only one input according to Input Voltage:
- L2/H2 240V Power input for GRX-TVI control (line/mains voltage must be 220-240V)
- L2/H2 127V Power input for GRX-TVI control (line/mains voltage must be 100-127V)
- N2 Neutral for GRX-TVI control
- DL2/DH GRAFIK Eye 3000 Series Control Unit Lighting Zone connection (Phase Control Input to GRX-TVI)
- L1/H1 Power input for lighting load
- N1 Neutral for lighting load (2 terminals provided and internally tied together — one for input neutral and one for load neutral)
- SL1/SH1 Switched output to power lighting load + – 0-10V control signal wires (ballast must provide a 0-10V source only)

Operation
After wiring is complete, supply power to the GRX-TVI 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 and 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 twice per second to signify proper communication between the Control Unit and the Interface.
Incorrect Operation – No Active Input
- The LED will repeatedly turn on for 1 second and then off for 1 second to indicate that there is not an active phase control input to the GRX-TV. Make sure that the phase control dimmer is ON and connected to the GRX-TVI at the terminal block marked DL2/DH2. Check that the corresponding zone for the DL2/DH2 terminal 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 the output can be checked by looking at the load and checking the operation from the Control Unit.
- For non-dimming ballasts, select the non-dim load type on the GRAFIK Eye Control Unit and do not connect ballasts to 0-10V terminals.
Make sure that the Control Unit 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.
