3. If the luminaire does not complete the verification procedure, follow the basic troubleshooting steps
in 9.2. Troubleshooting:
4. If the luminaire successfully finished the “Auto Detection and Verification” procedure, the LCU
physical installation is complete.
Note: Each time the main power to the pole is lost, the “Auto Detection and Verification”
procedure is executed when power is restored.
9.2 Troubleshooting
If the “Auto Detection and Verification” procedure is not successful, troubleshoot as follows:
To troubleshoot a LCU NEMA installation:
1. Remove the LCU plug by twisting the plug counterclockwise.
2. Wait 15 seconds.
3. Reseat the LCU in the receptacle securely.
As soon as the LCU is reseated, the “Auto Detection and Verification” procedure will start.
4. Observe the ON/OFF sequence.
5. If the “Auto Detection and Verification” procedure fails again, select and install a different LCU.
6. If the verification procedure fails with a different LCU, verify the following:
◦ The lamp driver and luminaire are working correctly.
◦ The receptacle is installed correctly.
