If additional nLight devices are not showing power from the nPP16 ER EFP relay pack, follow these troubleshooting steps as outlined in the manual:
1. **Confirm Bus Power:** Check if there is a device in the daisy chain that provides bus power, as "ER" devices do not supply bus power.
2. **Check Line Voltage:** Ensure that line voltage power is present and connected to the correct line voltage input wire, as indicated in the wiring diagram.
3. **Verify Wiring Connections:** Confirm that all line voltage wiring connections are secure and correctly made.
4. **Check RJ45 Connections:** Verify the RJ45 pinout connections and ensure there is no debris or bent pins within the RJ45 connections on all devices in the daisy chain.
5. **Cable Testing:** Use a CAT5 cable tester to confirm that all cables are properly terminated and functional.
6. **Avoid Cable Damage:** Ensure that no CAT5 cables are kinked or held with cable ties that are overtightened, as this can cause connectivity issues.
By following these troubleshooting steps, you can systematically identify and address the potential causes of the issue with additional nLight devices not receiving power from the nPP16 ER EFP relay pack.
