Dimmable Fixtures Not Dimming on Echoflex 0-10v

Issue 

When connecting a 0-10V controller to a dimming fixture or circuit, the fixture(s) fails to dim. They switch ON/OFF with switch action, but no fading.

Solution

First, confirm that the fixture or ballast is a type that supplies voltage. Echoflex controllers sink 0-10v; they do not source it. If you are using fixtures that expect source dimming, they are not compatible with Echoflex 0-10v controllers.

The controller has an auto-detect feature which will recognize when a dimming fixture is attached to the purple and grey 0-10V dimming lines.

1. Check the wiring. Loose dimming circuit wires is the most common cause of the fixtures not dimming properly.
2. Check the fixture. Is it working properly?
   1. Disconnect the dimming circuit's purple and grey wires at the controller.
   2. Short the fixture's grey and purple wires together; the fixture should go to its minimum intensity.
   3. Separate the fixture's grey and purple wires to open the circuit; the fixture should go to full bright. If these are not the results of the test, then the fixture is faulty.
3. Monitor the dimming circuit - use a digital multimeter to measure the DC voltage on the purple and grey wires with the fixture connected. You should see a range or about 1V to 10 VDC.
4. Clear the controller to factory defaults.
   1. Press and hold the controller's CLEAR button for 15 seconds until the red and green LEDs are lit solid.
   2. Press the controller's LEARN button to enter into link mode and link the wireless switch by clicking ON three times.
   3. Exit link mode by pressing the LEARN button again and test dimming using the switch.
   4. If the lights dim, then repeat steps a to c to link any other devices needed.
