7. Power up a DEPENDENT device, and verify that it passes its own power-up self-test. (Check voltage requirement first.)8. Check for ground fault between the DEPENDENT device and the RS-485 communication line. If applicable, find the fault and clear it.8. Check for ground fault between the DEPENDENT device and the RS-485 communication line. If applicable, find the fault and clear it.9. Connect the DEPENDENT device to the RS-485 line and bring in on-line.10. Verify all functions of the DEPENDENT device.11. Verify the RS-485 line voltage in reference to the signal ground (SG.)12. For each additional DEPENDENT device, repeat steps 7 through 11.13. Verify the RS-485 line voltage for the controller, and mark the readings on the inside of the controller panel for future reference.13. Verify the RS-485 line voltage for the controller, and mark the readings on the inside of the controller panel for future reference.System Testing
