GRX-PWM Control Interface
GRX-PWM-JA Control Interface
Phase Control to PWM
Description
The GRX-PWM provides 12 V Pulse Width Modulated (PWM)
control and ballast switching capabilities in one enclosure. With
the GRX-PWM, a GRAFIK Eye 3000 Series Control Unit* can
control PWM ballasts powered by 100-277 V and provide
switching relays that can handle the in-rush current for a full
circuit of ballasts. The GRX-PWM can also be used to switch any
of the load types listed below.
*GRX-PWM will also work with Lutron GP or LP panel outputs.
Note: When using a Control Unit, a GRX-PWM is required for each
12 V PWM fluorescent zone. (A 3-zone Control Unit with two
fluorescent zones and one incandescent zone is shown as an
example.)
Mounting
Find a suitable location for mounting.
•Decide on the proper location for the GRX-PWM (NEMA Type 1
enclosure, indoor use only). See System Wiring Layout below.
•The environment where the GRX-PWM 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.
•Mounting method must be able to support weight and forces
applied during installation.
•Internal relays will click while in operation; mount where
audible noise is acceptable.

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-PWM.
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 20 A
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 #12-20 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-PWM 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-PWM 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 terminals (H1& H2).
H1is the Hot feed to power the lighting load.
H2is the Hot feed that powers internal circuitry of the GRX-PWM.
H2has a 100/120 V connection. Do not use the unlabeled
terminal.
Note 1: Not all terminal blocks receive a connection.
Note 2: The power feed to the Control Unit and H2of the
GRX-PWM must be the same phase!
PELV (Class 2: USA), 12 V PWM wiring from a
ballast to the GRX-PWM must be separated from the
power wiring. Enter the PELV (Class 2: USA) wires
through the knockout adjacent to the 12 V PWM 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.

Operation
After wiring is complete, supply power to the GRX-PWM 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:
1. Standard Operation
•The LED will flash at a rate of twice per second to signify proper communication between the Control Unit and the Interface.
2. Incorrect Operation - No Active Input
•The LED will repeatedly turn on for 1 second, then off for 1 second, to indicate that there is not an active phase control input to
the GRX-PWM. Make sure that the phase control dimmer is ON and connected to the GRX-PWM 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 the output can be checked by looking at the load and
checking operation from the Control Unit.
•For non-dimming ballasts, select non-dim load type on the GRAFIK Eye Control Unit and do not connect ballasts to PWM’s + and -
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.
Solution
Verify that LED pulses twice per second. If not, check wiring from phase control unit to the
Interface.
Make sure that the GRAFIK Eye 3000 Series Control Unit is ON.
Check for proper polarity of PWM 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.
GRAFIK Eye 3000 Series Control Unit is not configured for fluorescent load type.
Check that the SH1connection goes to the ballasts.
Check that the DH2connection is actually wired to a phase control input.
Check that load is connected to SH terminal.
Check that the DH2connection is actually wired to a phase control input.
Check that power is applied to the Interface.
