Trouble Shooting the RLED 2

 Note: All references are to the RLED 2 Manual. 

Problem Description	Troubleshooting
The power is connected, yet the LEDs are off.	1. Check the power. 2. Check the main fuse F3. 3. Using a DVM, test the +5 and COM test points (refer to Figure 12). 4. Check flat cable connection.
Power is ON, but there is no Output when working in "AUTO" mode with "0-10V" control voltage.	Make sure the "+" and "COM" of "0-10V" cable is connected correctly. Set 5V from the controller and measure this value at the RLED 2.0 terminal.
Power is ON, but there is no Output when working in "AUTO" mode with communication lines.	1. Check the dipswitches and ensure that they are set correctly (refer to Figure 8 and Figure 9, page 16). 2. Check the wiring.
The lights blink when working at low voltage levels.	1. Make sure there is no inductive devices (for example transformers and power coils) integrated into the electrical load system. 2. In Options > Cn, change the Cn setting. This step requires recalibration. Refer to System Parameter 1 – Minimum Light Calibration (bu), page 9) 3. Apply Ignition Pulse.
Light is always at maximum brightness or you can't change the brightness.	Contact technical support.
