If no indicator lights up when feeding power to the GE Controller unit, there might be several reasons:
* **Insufficient power supply:** Verify the voltage level at the power supply terminals with a multimeter to ensure it's within the model's specified range.
* **Wrong versions:** Ensure that the relay and ENERVISTA 650 Setup versions are the same.
* **Fuse failure:** Remove the power supply, dismount the power supply module, and replace the fuse.
* **Loose fuse:** Perform the same steps as for a fuse failure, ensuring the fuse is correctly seated.
* **Incorrect wiring:** Double-check that the terminals labeled + and – are correctly connected to the corresponding power source on the 9-pin connector.

If the GE Controller relay is not communicating via the front RS232 port, consider the following:
* **Incorrect cable:** Ensure you are using a straight cable.
* **Damaged cable:** Replace the cable.
* **Relay or PC not grounded:** Ensure a ground connection is present.
* **Incorrect baudrate, port, address, etc.:** Test other ports and baudrates. Verify that the communication parameters on the computer match those of the relay.
