5. SYSTEM START-UP PROCEDURES

To avoid the need for difficult troubleshooting, system start-up must follow this step-by-step

procedure. Never wire up a system and apply power to it all at once.

L-1 EAS recommends always following these system start-up steps:

1. Do not apply power to any device.

2. Check all wiring and device configurations.

3. Disconnect all devices from the communication line.

4. Check the supply voltage for correct voltage.

5. Power up the PC running SecureAdmin.

6. Power up the RS-232 to RS-485 converter (if installed).

7. Configure SecureAdmin.

8. Perform a ground fault check for the converter (if installed).

9. Connect the PC and converter (if installed) to the communication line.

10. Verify that the device powers up correctly, but do not connect it to the communication line.

The power LED should be illuminated. Check the power lines with a voltmeter.

11. Perform a ground fault check for the device (if using RS-485, see Section 5.4 on next page).

12. Connect the device to the communication line.

13. Verify that the device communicates with SecureAdmin.

14. If there are more device, repeat Steps 10 through 13 for each device.
