10.2.3Auto Start

NOTE: Automode must be enabled to use this procedure.

1.Perform the Initial Setup procedures.

2.On SSBM, turn the SYSTEM MODE key switch to BYPASS momentarily.

3.Observe that CBP and FBP have closed.

4.On all UPMs, close CB1

5.On all UPMs, set BATTERY switch to NORMAL.

6.On all UPMs, set MODE switch to NORMAL.

7.On SSBM, turn the SYSTEM MODE key switch to NORMAL momentarily.

The UPM rectifiers turn on.

If a bypass source is available, the critical load is immediately supplied by the bypass source in Bypass mode until the the UPMs are available. The status indicators on the SSBM monitor screen indicate when the Parallel Capacity/Redundant system is in Bypass mode and Normal mode.

8.Observe that CBS is open and CBP is closed.

9.When UPM Battery Disconnected alarm and notification message is received, close UPM battery disconnect breakers.

The UPM inverters turns on. When each inverter reaches full voltage, K3 closes. Logic power is supplied and the UPM is ready to supply power to the critical load. It takes less than 1 minute for the UPM to achieve Normal mode.

10.Once the Parallel Capacity/Redundant system is redundant, the critical load is automatically transferred from bypass to the UPMs and system is operating in normal mode.

NOTE: If transfer is not completed within one minute, the SYSTEM MODE key switch must be turned momentarily to NORMAL again to achieve normal operation.
