Troubleshooting
Problem: LED option exhibits a flash or steppy dimming on first use
Drivers will "learn" the LED load on first start-up. This is a one-time event for a particular driver/LED combination. Running the load at full output for 20 seconds will complete the "learning" phase and will prevent LEDs from flashing or steppy dimming in future uses.
Problem: Light flashes on/off or does not turn on
Ensure the parameters of the LED array meet the specifications of the driver
Ensure wire length from driver to LED does not exceed limitations found in the brochure below
Ensure driver is being controlled either through an Ecosystem link or a Lutron 3-wire fluorescent dimmer
If a 3-wire dimmer is being used, check that dim hot and switch hot terminals are not swapped
For constant voltage drivers, ensure you are getting 120-277VAC to the input of the driver, and are reading the specified DC voltage on the output. If the output is correct with no load attached, the driver is working and Lutron suggests contacting the LED manufacturer
For constant current drivers, ensure you are getting 120-277VAC to the input of the driver and the DC voltage on the output will ramp up continuously with no load attached. This ensures the driver is working
Adjust the low end trim on the 3-wire dimmer
