, HIGH EVENT POINT 0920 INDICATED CONDITION:

o DPBA-1C IS DISCHARGING CURRENT >10 AMPS AS SENSED BY AMMETER 1 BUS 3 ALARM RELAY.

~

REDUNDANT INDICATION WHICH WILL VERIFY ALARM:

o DPDP-1C LOCAL CURRENT METER.

OPERATOR ACTIONS FOR A VALID ALARM:

I o VERIFY BATTERY CHARGER IS ALIGNED TO THE BUS AND OPERATIONAL.

SSF-Al ANNUNCIATOR RESPONSE SSF-Al-08-07 P-08-07 BATTERY C BREAKER OPEN EVENT POINT 1992 i

INDICATED CONDITION:

o- DPDP-1C CUBICLE 1 DISCONNECT FOR DPBA-1C IS OPEN AS SENSED BY AN 1

AUXILIARY SWITCH IN THE CUBICLE.

REDUNDANT INDICATION WHICH WILL VERIFY ALARM:

i o LOCAL DISCONNECT POSITION VERIFICATION.

OPERATOR ACTIONS FOR A VALID ALARM:

o ENSURE THAT BATTERY CHARGERS ARE IN SERVICE FOR BOTH BANKS OF DPBA-1C o INVESTIGATE THE CAUSE FOR THE DISCONNECT BEING OPEN.

o RECLOSE DPBA-1C DISCONNECT AS SOON AS POSSIBLE.

DISCUSSION:

THE BATTERY DISCONNECT CAN BE OPENED WITH THE BATTERY CHARGERS IN SERVICE AND STILL MAINTAIN DC POWER TO ALL LOADS. THE LOSS OF AC 1 POWER WITH THIS DISCONNECT OPEN WOULD CAUSE A COMPLETE LOSS OF ALL NON-1E DC LOADS.
