LEGEND [I::- SEQUENCE OF OPERATION PROCESS WATER BOOSTER PUMPS: BP-3A AND 3B A. SYSTEM CONSISTS OF: • TWO PUMPS: BP-3A AND 3B. • A DIAPHRAGM TANK. • AN ANALOG ELECTRONIC PRESSURE SENSOR ON THE BOOSTER SYSTEM INLET AND DISCHARGE. • VARIABLE FREQUENCY DRIVES FOR EACH PUMP MOTOR. • MANUFACTURER'S SAFETY THERMAL/PRESSURE RELIEF ON EACH PUMP. • THE SYSTEM SHALL MAINTAIN DISCHARGE PRESSURE BETWEEN MINIMUM AND MAXIMUM PRESSURE SPEEDINSHALLABE SET^BYNITABBANDOSHALOL BED UBSEDAFORLSOFT AQNDNCOMPENSATNIGI^LOW SUCTION GENERAL NOTES PRESSURE. MINIMUM PUMP SPEED SHALL BE SET TO MAINTAIN MINIMUM FLOW PER MANUFACTURER (8GPM) PLUS 10%. B. PUMP START/STOP IS AUTOMATIC AND CONTROLLED BY MINIMUM AND MAXIMUM DISCHARGE PRESSURE AND STOP BY HIGH DISCHARGE WATER TEMPERATURE. • LEAD PUMP WILL ALTERNATE DAILY. • LAG PUMP WILL START IF THE LEAD PUMP IS UNABLE TO MAINTAIN DISCHARGE PRESSURE. • LAG PUMP WILL BECOME LEAD IF LEAD PUMP IS IN ALARM CONDITION. C. PUMP START/STOP — SETPOINT FOR DISCHARGE PRESSURE (70 PSI) WILL BE ADJUSTABLE (AT FBI). • LEAD PUMP STARTS AT MINIMUM SPEED WHEN SYSTEM DISCHARGE PRESSURE IS BELOW 70 PSI (ADJ.). PUMP SHALL INCREASE SPEED AS NEEDED TO MAINTAIN DISCHARGE PRESSURE TO PREVENT OVERSHOOTING SET POINT AND SHORT CYCLING. • LAG PUMP STARTS AND SLOWLY RAMPS UP TO SPEED WITHIN TO ALLOW LEAD PUMP TO COMPENSATE AND PREVENT SHORT CYCLING OR OVERSHOOTING THE SEfPOINT WHEN SYSTEM DISCHARGE PRESSURE BELOW 70 PSI (ADJ.) FOR 15 SECONDS (ADJ.) AND LEAD PUMP SPEED IS ABOVE 85% (ADJ.). • BOTH PRESSURE PUMPS ARIES OR DROPS BELOW 70 1 %(ADJ SPEED IN UNISON AS SYSTEM DISCHARGE PSI REFERENCE D RAW N G S • LAG PUMPS STOP — SYSTEM DISCHARGE PRESSURE AT 70 PSI (ADJ.) FOR 90 SECONDS (ADJ.) AND BOTH PUMP SPEED IS BELOW 40% (ADJ.). • LEAD PUMP WILL STOP — SYSTEM DISCHARGE PRESSURE AT 70 PSI (ADJ.) FOR 90 SECONDS (ADJ.) AND LEAD PUMP AT MINIMUM SPEED. D. SUCTION PRESSURE: • PUMP SYSTEM WILL BE DISABLED WITH SUCTION PRESSURE (INLET PRESSURE) DROPS BELOW 40 PSI (ADJ.) FOR 10 SECONDS (ADJ.). • PUMP SYSTEM WILL BE RE—ENABLED WHEN SUCTION PRESSURE (INLET PRESSURE) IS BELOW 20 PSI (ADJ.) FOR 300 SECONDS (ADJ.) TO AVOID SHORT CYCLING PUMPS. E. DISCHARGE HIGH TEMP: • PUMP WILL BE DISABLED WITH HIGH DISCHARGE TEMPERATURE OF 100 DEG. F (ADJ.) AND 10 MINUTES (ADJ.). • PUMP WILL BE MANUALLY RE—ENABLED AFTER INVESTIGATION OF THE CAUSE OF SHUTDOWN IS COMPLETE. F. ALARM AT FMCS WITH: • PUMP FAIL ALARM: PUMP FAIL ALARM IS GENERATED WHEN PUMP IS COMMANDED ON BUT THE STATUS IS OFF, OR WHEN THE PUMP IS COMMANDED OFF BUT THE STATUS IS ON. (CRITICAL ALARM) CONSTRUCTION NOTES • PUMP VFD FAULT ALARM (CRITICAL ALARM). • HIGH TEMP DISCHARGE ALARM ABOVE 100 DEG. F (ADJ.). (CRITICAL ALARM). SETPOINTS TO BE DETERMINED DURING • PRESSURE ALARMS (CRITICAL ALARM): COMMISSIONING. 1. LOW DISCHARGE PRESSURE < 55 PSI (ADJ.) AND 10 SECONDS (ADJ.). 2. HIGH DISCHARGE PRESSURE > 100 PSI (ADJ.)
