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 +Phase dimming is one of the most common dimming methods for LED fixtures. The term "phase dimming" actually encompasses several dimming technologies which all operate on the same basic principal of chopping up the AC voltage being delivered to the fixtures or drivers.

13 +Phase dimming can be broadly divided into two categories: forward phase dimming and reverse phase dimming. Forward phase dimming operates by cutting off the front (leading edge) of the AC sine wave, while reverse phase dimming cuts off the back (trailing edge) of the AC sine wave. See the //[[real world data>>WebHome||anchor="HRealWorldPhaseDimmingData"]]// below for an illustration.

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). This general procedure is as follows:
