I have just installed a new Lutron Caseta PRO Dimmer PD-10NXD replacing an operating Lutron SPSLV-600. The load is a single Iris recessed can with a 12 volt, 50 watt MR-16 lamp. This fixture includes an integral magnetic step down transformer, 120V 50/60Hz input, 12V, 50VA nominal output. I have wired the Dimmer as instructed including the white neutral. This is s single-pole installation, so the blue wire is simply terminated. See the attached image.
All other Lutron Caseta PD-6WCL dimmers in the same J-box operate correctly. When the circuit is turned on:
• I can detect voltage in the Blue, Black and Red wires but not the White wire
• The lamp does not turn on.
• Each of dimmer LED's flash on briefly from bottom to top, then after a three second delay, the top and middle LEDs begin flashing quickly.
See the attached video.
According to the Caseta Wireless Advanced Installation Guide, Troubleshooting, page 73, these symptoms indicate, "Product detected an MLV fault (PRO Dimmer only) • Connect Neutral to the dimmer (required for MLV load)."
As I have connected the Neutral to the Dimmer, what do you suggest?
Thanks so much for your help.
