System Operation

4.1 System Commissioning

The following section should be used to power-up the system for the first time.

Step 1 Turn on AC breakers at the AC distribution panel to power up the shelf through the rectifiers.

Step 2 The controller and rectifier LEDs will start to blink. It may take a few minutes for the controller to communicate with all rectifiers.

Step 3 The system is now commissioned. If the controller RED LED s on, refer to “Chapter 5, “System Troubleshooting.”

4.2 General Information

The Power Control System (XCS) (Figure 4-1) is a supervisory system that is designed to control AC/DC power systems that are based on XR1648 rectifier modules.

Communication is accomplished through an alarm interface board and a backplane that connects to the rectifier modules.
