TGF-N ANNUNCIATOR RESPONSE TGF-AX2-03-02 N-03-02 CDSTE PUMP B UNCOUPLED EVENT POINT 0090 INDICATED CONDITION:
o CDP-1B MOTOR RUNNING CONTROLLED FROM THE SPARE CONTROLLER AND A LOW VOLTAGE IS SENSED ON THE MAGNETIC COUPLING CONTROLLER OUTPUT.
f~'%
b REDUNDANT INDICATION WHICH WILL VERIFY ALARM:
o CDP-1B PUMP NOT ROTATI'NG.
o CONDENSATE FLOW DECREASING.
OPERATOR ACTIONS FOR A VALID ALARM:
o SWAP CDP-1B TO NORMAL CONTROLLER PER OP-603.
o IF CDP-1B CANNOT BE CONTROLLED THEN REDUCE PLANT POWER TO A LEVEL AT WHICH 1 CONDENSATE PUMP CAN SUPPLY SUFFICIENT CONDENSATE FLOW. <
l DISCUSSION:
THIS ALARM INDICATES THE CONTROLLING VOLTAGE SIGNAL TO THE MAGNETIC COUPLING ON THE CONDENSATE PUMP IS LOW. THIS WILL CAUSE THE PUMP TO STOP.
THIS IS A NORMAL ALARM WHEN SHUTTING DOWN A CONDENSATE PUMP.
