External Dimensions of CRESTRON GREEN LIGHT Architectural Dimming Cabinets
NOTE: All wiring must be installed in accordance with all local and national electrical codes.
NOTE: Refer to the torque settings specified on pages 6, 7 and 8.
CRESTRON GREEN LIGHT cabinets are shipped with GLX modules installed and prewired to the branch circuit
breakers. The following must be performed after installation:
• Connect incoming feed conductors to the breaker panel (section A of the following diagram)
• Connect load wiring to GLX module outputs (section B of the following diagram)
• Connect control wiring (section C of the followi ng diagram)
CAUTION: Bypass jumpers are provided on each output to allow testing and to protect the module during
installation. The jumper shorts the L, SW and DM terminals so that the load circuit is energized when the branch
breaker is on. Do not remove the bypass jumper until all feed and load wiring has been completed, and th e circuits
have been tested for electrical faults.
NOTE: Use copper conductors only – rated 75°C.

2. Test the circuit for electrical faults by turning on each circuit breaker, checking that the breakers do not
trip, and that power is delivered to the proper loads.
3. Turn off the circuit breaker(s) and remove all jumpers.
4. Turn on the circuit breakers.
Control Wiring (Section C)
The bottom of the cabinet contains Cresnet® connections for interfacing to the rest of the Crestron® control system.
It also provides an override input which can be tied to devices such as the GLS-PLS-120/277 phase-loss sensor, or
other devices that provide a dry contact closure (manual switch, fire alarm relay, etc.).
NOTE: Interface connectors for NET (x2), POWER (x3), and OVERRIDE (x3) ports are pr ovided.
When wiring the supplied NET connectors for connection to a Crestron control system or other device on the
Cresnet network, use Crestron certified wire such as CRESNET-NP or CRESNET-P.
To ensure optimum performance over the full range of your installation topology, use Crestron certified wire.
Failure to do so may incur additional charges if support is required to identify performance deficiencies because
of using improper wire.
When daisy-chaining connections between NET ports, strip the ends of the wires carefully to avoid nicking the
conductors. Twist together the ends of the wires that share a pin on the network connector, insert the connection
into the Cresnet connector, and tighten the retaining screw. Repeat the procedure for the other three conductors.
POWER Port Wiring
Low voltage (24 VDC) power must be supplied to the modules either internally via devices connected to the
NET port or externally via a Cresnet power supply connected to the POWER port.
To power the modules internally from line power, install a jumper from the INT pin on the supplied POWER
connector to the EXT pin on the POWER connector as shown in the following diagram.
Providing Cresnet Power Internally
When a lighting module is powered from line power, the module’s PWR LED will illuminate.
To power the modules externally from a Cresnet 24 VDC power supply, connect the external power supply to
the EXT and G pins on the POWER supplied connector as shown in the following diagram.
Providing Cresnet Power Externally
When properly connected and receiving 24 VDC power externally, the green LED next to the MODULES port
will light.
Under normal operation, each lighting module will draw power from the line voltage on circuit 1. In this case
the green PWR LED on the module will be lit. If AC power to circuit 1 is interrupted for some reason (e.g.
because the breaker trips), the module will automatically draw power from the 24VDC supply, if available. In
this case, the PWR LED will flash.
OVERRIDE Port Wiring
Low-voltage input devices such as the Crestron GLS-PLS-120/277 phase-loss sensor or any device that
provides a dry contact closure can be connected to the supplied OVERRIDE connector on the bottom of the
cabinet.
When a dry contact closure is applied to the OVERRIDE terminals, all modules in the cabinet will enter into
Override mode. In this mode they will recall their override levels, and will ignore any external commands (e.g.
from keypads, touchpanels, or timeclock events) until the override contacts are removed.
For more details, refer to “Override Mode” on page 11.
A lighting module can be manually controlled from its front panel.
Switch Function
The GLX-HSW8 is a power switching module that can be used to turn loads on and off.
The GLX-DIM6 and the GLX-DIMFLV8 are dimming modules whose outputs can be set to operate as
dimmable or non-dimmable outputs. The state of each output can be manually controlled from the front panel.
To use a module’s switch function:
•Ensure that the output’s mode switch is set to NON-DIM (GLX-DIM6 and GLX-DIMFLV8 only).
The DIM LED will be off.
•Press the S button to turn the output on. The corresponding ON LED illuminates and the output state
is shown on the NET ID display (“On” for on) for two seconds after the button is released.
•Press the T button to turn the output off. The corresponding ON LED extinguishes and the output
state is shown on the NET ID display (“oF” for off) for two seconds after the button is released.
NOTE: The control system program may change the settings if the Override mode is not enabled.
Dimming Function (GLX-DIM6 and GLX-DIMFLV8 Only)
The lighting level of each of the outputs can be manually controlled from the front panel.
• Ensure that the output’s mode switch is set to DIM (GLX-DIM6 and GLX-DIMFLV8 only).
• Press the S button to turn the output on (100%). The corresponding ON and DIM LEDs illuminate
and the output state is shown on the NET ID display (“On” for on) for two seconds after the button is
released.
•Press the T button to turn the output off. The corresponding ON LED extinguishes and the output
state is shown on the NET ID display (“oF” for off) for two seconds after the button is released.
•To ramp the lighting level up or down (until it reaches 100% or turns off), press and hold the output’s
S or T button. The corresponding ON LED illuminates while the load is ON. The DIM LED
illuminates while the output level is less than 100%. The output level is shown on the NET ID display
as a percentage (01-99, “oF” for off, or “On” for on) for two seconds after the button is released.
NOTE: The control system program may change the settings if the Override mode is not enabled.
Override Mode
The Override mode overrides the control system program and sets all of the output states to the stored override
values. For instructions on saving override sett i ngs, refe r t o “Save O verri d e Setti ngs” on page 12.
To enable Override mode, press and release the OVR button. The OVR LED flashes slowly.
NOTE: If the Override mode was enabled from an external device (i.e. a contact closure is present on the
OVERRIDE terminals), the OVR LED will flash quickly. Pressing the OVR button has no effect.
To disable Override mode, press the OVR button again. The OVR LED extinguishes and the outputs return to the
states set by the control system program.
NOTE: If override states have not been stored, the factory default override state is all loads on.
The state of each output can be saved as an override setting, which can be automatically recalled when the Override
mode is enabled.
NOTE: The control system program has a setting that can prevent locally saving the override state. If this setting is
enabled, the display shows “Er” when trying to save override states. For more information, refer to the SIMPL
Windows help file.
To save the state of all of the outputs as an override setting, press and hold the OVR button for three seconds. The
OVR LED blinks to indicate the new override settings have been stored.
