11 -0-10V dimming is one of the most common dimming methods for LED fixtures. It utilizes a 0-10VDC signal from the lighting controller to the fixture power supply or driver in order to control the brightness of the fixtures. This 0-10VDC signal is typically carried over a shielded pair of gray (negative) and violet (positive) wires. In the event that 0-10V dimming fixtures are exhibiting unexpected dimming behavior, an easy place to begin troubleshooting is at the lighting control module.
11 +0-10V dimming is a common type of dimming protocol for LED fixtures. 0-10V dimming uses an analog DC signal in order to command the fixture driver to raise or lower the lights. The dimming signal is a steady voltage output between 0V and 10V, with lower voltages corresponding to a lower desired brightness.

15 -Crestron produces a variety of 0-10V lighting controllers, and the specifics for troubleshooting them varies slightly. That being said, there is a general procedure for testing 0-10V dimming modules that is applicable to any type of 0-10V controller (even non-Crestron controllers).

17 -The general 0-10V troubleshooting procedure is as follows:
17 +== Sub-paragraph ==
18 18  
19 -1. Identify the module and output that should be dimming the fixtures
20 -1. Disconnect the 0-10V wiring to the fixtures
21 -1. Connect a multimeter to the 0-10V dimming output of the module
22 -1. Measure the 0-10V output at various brightness levels
23 -1*. If the system has been partially or fully commissioned, it may be possible to use the showrunner UI to adjust the brightness
24 -1*. Alternatively, some modules have physical buttons that can be used to adjust their brightness:
25 -1**. Press the button to toggle the output on or off. A small LED light on the module will indicate current output on/off status.
26 -1**. Once the output is on, press and hold the button to cycle dim the output (first press and hold will lower the output, subsequent press and holds will toggle between raising and lowering the output)

32 -Verify that the 0-10V wiring in the field is not shorted. Try shorting the 0-10V wiring to the fixtures and observe the result. The fixtures should dim to about 50% brightness.
33 -
34 -Verify that the 0-10V wiring is correct at the fixture drivers (e.g. that the positive and negative wires did not get mixed up).
35 -
36 -Verify that the fixture drivers are actually 0-10V drivers; if the drivers are DALI or some proprietary dimming protocol, then they are not compatible with 0-10V lighting controllers. Either the drivers will need to be replaced or the lighting control system will need to be replaced.

47 -== Specific Modules ==
48 -
49 -The below sub-sections cover specific dimming procedures for various 0-10V controllers produced by Crestron.
50 -
51 -=== ZUMNET-JBOX-16A-LV and ZUMLINK-JBOX-16A-LV ===
52 -
53 -Zūm Wired JBOXs mount to a 1/2" knockout of a standard junction box.
54 -
55 -Inside the junction box will be two flying leads for the 0-10V dimming output. The grey lead is for the negative output and the violet lead is for the positive output. These leads should be wire nutted or lever nutted with the wiring to the fixtures. The leads should disconnected from the fixtures during troubleshooting.
56 -
57 -On the front of the Zūm JBOX-16A-LV (outside the junction box) are two or three LEDs next to a black button. The LED labeled "TEST" will be green if the output is hot. The black button can be used to toggle the output on or off, and holding the button will cycle dim the 0-10V output.
58 -
59 -See //[[Figure 1>>WebHome||anchor="HFigure1"]]// for details.
60 -
61 -=== CLX-2DIMFLV8 and CLX-2DIMFLV8-277 ===
62 -
63 -0-10V CLX modules are installed inside CAEN panels, which are typically located inside an electrical room or an MDF/IDF closet.
64 -
65 -Each CLX module has eight outputs split into two groups: outputs 1 through 4 are in the first group, while outputs 5 through 8 are in the second group. Even if there are no loads in the first group of outputs, the module still requires a line voltage input in order to function. The second group of loads will appear to be able to be toggled on and off, but the outputs will not change unless the second group of outputs is receiving a line voltage input. The line voltage input for the second group of outputs does not need to be on the same circuit as the line voltage input for the first group, but it must be on the same phase.
66 -
67 -On the front of 0-10V CLX modules are eight buttons corresponding to each of the eight outputs. Next to each button is a red LED indicating the current load status. The LED will be lit if the output is on. To the right of the LED is the 0-10V output for each channel, which can be easily unplugged for troubleshooting. The buttons can be used to toggle each channel independently, and holding the button will cycle dim the 0-10V output for that channel.
68 -
69 -See //[[Figure 2>>WebHome||anchor="HFigure2"]]// for details.
70 -
71 -=== GL-EXP-DIMFLV-CN ===
72 -
73 -GL-EXP-DIMFLV-CN are single-channel expansion modules used to provide additional 0-10V control to a system. They are self-contained and are surface mounted directly to a wall or ceiling.
74 -
75 -In order to access the 0-10V output, the front of the module must be removed. Inside the module is a paper barrier separating the high voltage switched output and 0-10V dimming (on the left) from the low voltage control wiring (on the right). A small flathead screwdriver is required to disconnect the 0-10V wiring to the fixtures.
76 -
77 -The "ON/OFF" light on the front of the module indicates the current output status (red means the output is on), and the button next to it can be used to toggle the output on or off. Press and hold the button to cycle dim the 0-10V output.
78 -
79 -The ON/OFF button sits proud of the module cover, so care must be taken when replacing the cover to avoid damaging the button.
80 -
81 -=== GLPP-DIMFLVCN-PM, GLPP-1DIMFLV2CN-PM, and GLPP-1DIMFLV3CN-PM (Discontinued) ===
82 -
83 -GLPPs mount to two 4" junction boxes. The left junction box has low-voltage wiring for Cresnet and sensors, while the right junction box has high-voltage wiring to the fixtures.
84 -
85 -Inside the right junction box will be at least two flying leads for the 0-10V dimming output. The grey lead is for the negative output. Depending on the module, there will be one or more violet leads for the positive output. Each lead will be labeled "DIM OUT #" to indicate which output they correspond to. These leads should be wire nutted or lever nutted with the wiring to the fixtures. The leads should disconnected from the fixtures during troubleshooting.
86 -
87 -There are no manual controls on the GLPP that allow for dimming the output. GLPPs can only be dimmed through the lighting UI or with the use of a GLPPA-REMOTE-PROG programming remote. If using a remote to dim the outputs, the remote must have line of site with the IR receiver on the front of the GLPP. The GLPP remote has four columns of buttons; columns 1 through 3 contain separate ON/OFF, raise, and lower buttons for individual outputs. The fourth column contains these same buttons, but will control all outputs simultaneously.
88 -
89 -One common source of dimming issues with multi-channel GLPPs is mixing up the switched outputs and the dimming outputs; fixtures should have their 0-10V dimming connected to the dimming output associated with the switched output that controls them.
90 -
91 -=== GLPAC-DIMFLV4 and GLPAC-DIMFLV8 (Discontinued) ===
92 -
93 -GLPAC modules are self contained and typically installed above the ceiling in the room they control.
94 -
95 -Each GLPAC module has either four or eight outputs depending on the model. Each output has its own line voltage input. Even if there are no loads on the first output, the GLPAC still requires a line voltage input in order to function. The line voltage input for subsequent outputs do not need to be on the same circuit as the line voltage input for the first output, but they must be on the same phase.
96 -
97 -On the front of the GLPAC are either four or eight buttons corresponding to each of the outputs. Next to each button is a green LED indicating the current load status. The LED will be lit if the output is on. The buttons can be used to toggle each channel independently, and holding the button will cycle dim the 0-10V output for that channel.
98 -
99 -The 0-10V outputs are located on the top right of the module. A small screwdriver is required to disconnect the dimming to the fixtures.
100 -
101 -See //[[Figure 3>>WebHome||anchor="HFigure3"]]// for details.
102 -
103 -=== GLXP-DIMFLV8 (Discontinued) ===
104 -
105 -0-10V GLXP modules are installed inside GLEP panels, which are typically located inside an electrical room or an MDF/IDF closet.
106 -
107 -Each GLXP-DIMFLV8 module has eight outputs, each with its own line voltage input. Even if there are no loads on the first output, the GLXP still requires a line voltage input in order to function. The line voltage input for subsequent outputs do not need to be on the same circuit as the line voltage input for the first output, but they must be on the same phase.
108 -
109 -On the front of GLXP modules are eight buttons corresponding to each of the eight outputs. Next to each button is a green LED indicating the current load status. The LED will be lit if the output is on. The buttons can be used to toggle each channel independently, and holding the button will cycle dim the 0-10V output for that channel. When dimming, the LCD "NET ID" screen will indicate the current expected brightness level.
110 -
111 -The 0-10V outputs are split into the eight negative outputs and the eight positive outputs on the lower left of the module. A small screwdriver is required to disconnect the dimming to the fixtures.
