I have a 40 watt 2'x2' led ceiling panel with a dimmable driver. With the purple and gray 0-10v circuit left open, the light operates at full brightness.
Considering the following (Pathwayconnect.com: Best Practices for Dynamic 0-10VDC LED Lighting Control) "When the purple and grey wires are open (not touching each other or connected to anything else) the dimming signal will be 10VDC and the output of the driver will be 100%. When the purple and grey wires are shorted together (touching each other) the dimming signal will be 0VDC the output of the driver will be set to the minimum dimming level or the driver will drop in to “sleep mode” and turn off the LEDs completely."
In simplest form, applied to a single panel, would it be accepatable to connect a rheostat (approx 2K) across the purple and gray wires to use as a variable series resistor to transverse the range: short to nearly open?
