10.2.2 Manual Start
1. Perform the Initial Setup procedures.
2. On SSBM, turn the SYSTEM MODE key switch to BYPASS momentarily.
IfabypasssourceisavailablewhenyouturntheSYSTEM MODE key switch to
BYP ASS, the critical load is immediately supplied by the bypass source in Bypass
mode until the the UPMs are available and the SSBM has been manually transferred
to Normal mode. The status indicators on the SSBM monitor screen indicate when
the
Parallel Capacity/Redundant system is in Bypass mode and Normal mode.
3. Observe that CBP and FBP h ave closed.
4. On first UPM, close CB1.
5. Observe UPM monitor screen becoming active as an indication of logic power.
6. VerifyUPMisshownontheSSBMmimicscreen.
7. On first UPM, set BATTERY switch to NORMAL.
8. On first UPM, set MODE switch to NORMAL.
9. On first UPM, turn the START switch to the right for 2 seconds and then
release.
10. When UPM Battery Disconnected alarm and no tification is received, close first
UPM battery disconnect breaker.
11. On first UPM, turn the START switch t o the right momentarily.
The rectifier turns on, then the inverter turns on. When the 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 t han 1 minute for the U PM to achieve Normal mode.
12. Start remaining UPMs by repeating steps 4 through 10.
13. On SSBM monitor screen, check for On Bypass, UPMs Ready message.
14. If message appears, turn the SSBM SYSTEM MODE key switch to NORMAL
