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.
	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.

	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).

	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)

	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.
