Operational Controls

and Features

8.1General

The Parallel Capacity/Redundant system should function automatically and require very little attention during normal operation. The controls and indicators identified in this section are used during startup, to monitor normal operation and during abnormal events.

Figure 8---1 (sheets 1 thru 4) identify and show the location of the controls and indicators on the typical Switchboard System Bypass Module (SSBM) control section. The following descriptions provide a brief overview of the SSBM controls, and standard and optional features.

NOTE: Read the Operation section and have thorough knowledge of Parallel Capacity/Redundant operation before attempting to operate. For a more detailed description of UPS operation, refer to Powerware 9315 Operation manual supplied with the UPS system.

8.2SSBM Standard Features

The SSBM has many standard features that provide cost-effective and consistently reliable power protection:

8.2.1Control Panel

The Control Panel on the front of the SSBM control section contains an LCD screen to display the current status of the Parallel Capacity/Redundant system. You can view a statistical history and log of system events and display a real-time graphic representation of power flowing through the system components. Backlit status indicators show the operating mode of the SSBM and alert you to system events. The SYSTEM MODE switch, also located on this panel, is used to start and stop the system and transfer the load between normal UPM operation and bypass operation. The EMERGENCY UPM OFF pushbutton is located at the top of the control panel, and the PUSH IN TO RESET button for EMERGENCY UPM OFF is located above the SYSTEM MODE switch. The Control Panel is described in chapter 9, “Using the Control Panel”.

8.2.2SSBM Circuit Breakers

The SSBM contains three circuit breakers, the System Output Breaker (CBS), the System Bypass Breaker (CBP), and the Backfeed Protection Breaker (FBP). CBS connects the output of the UPMs to the critical load. CBP is used as the bypass supply in the event the output of the UPMs are not available and to supply the critical load during maintenance. FBP is used to prevent power from being fed back to the UPMs in the event the static switch fails. These breakers are electrically controlled by the SSBM and are automatic in operation.
