PER 2015 INTERNATIONAL BUILDING CODE, MECHANICAL EQUIPMENT AND COMPONENTS, INCLUDING THEIR SUPPORTS AND ATTACHMENTS, SHALL BE DESIGNED FOR SEISMIC FORCES IN ACCORDANCE WITH

CHAPTER 13 OF ASCE 7-10.

EXTERIOR EQUIPMENT (INCLUDING ROOF CURBS AND ROOF RAILS) EXPOSED TO WIND SHALL BE DESIGNED AND INSTALLED TO RESIST THE WIND PRESSURES DETERMINED IN ACCORDANCE WITH CHAPTERS 26

THROUGH 29 OF ASCE 7-10.

REFERENCE THE STRUCTURAL DRAWINGS FOR SITE SPECIFIC INFORMATION ON SEISMIC DESIGN

CATEGORY, WIND SPEED, ETC.

REFER TO SPECIFICATIONS TO DETERMINE SEISMIC RESTRAINT REQUIREMENTS FOR EACH COMPONENT.

FOR COMPONENTS REQUIRING SEISMIC RESTRAINT, THE COMPONENTS SUPPORTS AND ATTACHMENTS

SHALL BE DESIGNED BY A REGISTERED DESIGN PROFESSIONAL.

WHERE SEISMIC RESTRAINT IS REQUIRED, HOUSEKEEPING PADS NEEDED FOR THE INSTALLATION OF EQUIPMENT UNDER THIS CONTRACT SHALL BE DESIGNED BY THE SEISMIC ENGINEER. DO NOT POUR

HOUSEKEEPING PADS PRIOR TO THE RECEIPT OF APPROVED SEISMIC SUBMITTAL.

SEISMIC RESTRAINTS FOR GENERATOR EXHAUST, SCR, PIPING AND CONDUIT SHALL BE SHOWN ON SEISMIC SUBMITTAL LAYOUT DRAWINGS SHOWING SPECIFIC RESTRAINT LOCATIONS ALONG WITH ACCOMPANYING

DETAILS AND CALCULATIONS.

NOTES:

EQUIPMENT 20 LBS. OR LESS IS EXEMPT IF FLEXIBLE CONNECTIONS ARE PROVIDED BETWEEN THE

COMPONENT AND ASSOCIATED PIPING AND CONDUIT.

RESTRAINTS ARE NOT REQUIRED IF THE COMPONENT WEIGHS 400 LBS. OR LESS, IS MOUNTED AT 4 FT. OR LESS ABOVE A FLOOR, AND HAS FLEXIBLE CONNECTIONS BETWEEN THE COMPONENT AND ASSOCIATED

PIPING AND CONDUIT.

FLEXIBLE CONNECTIONS REQUIRED FOR PIPE CONNECTIONS ONLY.

RESTRAINT IS NOT REQUIRED IF THE PIPING IS SUPPORTED BY HANGERS AND EACH HANGER IN THE PIPING RUN IS 12 IN. OR LESS IN LENGTH FROM THE TOP OF THE PIPE TO THE SUPPORTING STRUCTURE. WHERE PIPES ARE SUPPORTED ON A TRAPEZE, THE TRAPEZE SHALL BE SUPPORTED BY HANGERS HAVING A LENGTH OF 12 IN. OR LESS. WHERE ROD HANGERS ARE USED, THEY SHALL BE EQUIPPED WITH SWIVELS, EYE NUTS OR

OTHER DEVICES TO PREVENT BENDING IN THE ROD.

GENERATOR START SEQUENCE AND NOTES (MECHANICAL ONLY)

GENERAL NOTE: WHERE SEQUENCE INDICATES A VALVE TO OPEN OR CLOSE, INFER VALVE SHALL BE "COMMANDED AND VERIFIED" OPEN OR CLOSED.

NOTE: LEVEL AND TEMPERATURE SHUTDOWN ALARMS MUST ALL BE HARD WIRED AND PROGRAMMED IN THE PLANT CONTROL SYSTEM (PCS) IN THE

CONTROL SYSTEM CABINET.

THE GENERAL START SEQUENCE WILL DIFFER BETWEEN MANUFACTURERS BUT SHOULD BE CONSISTENT TO INCLUDE THE FOLLOWING:

ON INITIAL START COMMAND FROM THE PCS (LOSS OF POWER OR MANUAL START). EACH GENERATOR WILL GO THROUGH THE VITAL SYSTEMS

NEEDED TO START AND MUST BE VERIFY AND CHECK START PERMISSIVES DURING A BLACK START EVENT. (THE ORDER MIGHT BE DIFFERENT PER

MANUFACTURER AND MUST BE CONFIRMED WITH THE GENERATOR MANUFACTURER ACTUAL PERMISSIVES FOR A BLACK START.)

1. PCS WILL VERIFY COMPRESSED AIR PRESSURE IS ABOVE THE MINIMUM PRESSURE (REFER TO COMPRESSED AIR SEQUENCE FOR OPERATING

PRESSURES).

2. PCS WILL COMMAND COMPRESSED AIR INLET VALVE TO THE GENERATOR FULLY OPEN TO THE GENERATOR COMPRESSED AIR START

SOLENOIDS. COMPRESSED AIR INLET MUST HAVE FEEDBACK TO THE PCS THAT THE VALVE IS FULLY OPEN.

3. PCS MUST COMMAND THE INLET AND OUTLET VALVES FOR THE TWO ASSOCIATED COOLING WATER PUMPS FULLY OPEN. INLET AND OUTLET

PUMPS HAVE FEEDBACK TO THE PCS THAT THE VALVE IS FULLY OPEN.

4. PCS MUST VERIFY INTAKE AIR FILTER IS FUNCTIONAL AND READY FOR OPERATION.

a. THE PCS MUST VERIFY STATUS AND CONFIRM AIR INTAKE FILTER CONTROLLER IS NOT IN ALARM.

b. THE PCS MUST COMMAND AND VERIFY INTAKE AIR DAMPER IS FULLY OPEN. INTAKE AIR DAMPER MUST HAVE FEEDBACK TO THE PCS

THAT THE DAMPER IS FULLY OPEN.

c. THE PCS MUST COMMAND AND VERIFY COMPRESSED AIR INLET VALVE IS FULLY OPEN. INLET COMPRESSED AIR MUST HAVE FEEDBACK

TO THE PCS THAT THE VALVE IS FULLY OPEN.

5. PCS WILL VERIFY EXHAUST DIVERTER VALVE IS IN THE CORRECT POSITION FOR NORMAL GENERATOR OPERATION.

6. GENERATOR CONTROLLER WILL OPEN PRELUBE AIR MOTOR SOLENOID VALVE AND TURN OVER THE PRELUBE MOTOR. GENERATOR

CONTROLLER MUST VERIFY LUBE OIL FLOW THROUGH THE ENGINE.

7. GENERATOR CONTROLLER WILL OPEN THE MAIN SOLENOID VALVE TO THE AIR START MOTORS FOR ENGINE START.

8. WHEN GENERATOR STARTS AND IF READY TO ASSUME LOAD THE ELECTRICAL SEQUENCE MUST BE INITIALIZED AND CLOSE THE BREAKER TO THE

PLANT BUS.

9. AFTER GENERATOR START ALL SYSTEMS MUST BE STARTED AND VERIFIED AS DIRECTED IN THIS SEQUENCE OF OPERATIONS.

THESE PERMISSIVES FOR A BLACK OR NORMAL START MUST BE THE SAME FOR BOTH POSSIBLE SCENARIOS. CONFIRM WITH THE GENERATOR

MANUFACTURER ON THE ABOVE PERMISSIVES.

FUEL OIL SYSTEM OPERATING PROCEDURE

FUEL DISTRIBUTION SYSTEM AND OVERFLOW CONTROLS:

GENERAL NOTE: WHERE SEQUENCE INDICATES A VALVE TO OPEN OR CLOSE, INFER VALVE SHALL BE "COMMANDED AND VERIFIED" OPEN OR CLOSED.

NOTE: LEVEL AND TEMPERATURE SHUTDOWN ALARMS MUST ALL BE HARD WIRED AND PROGRAMMED IN THE PLANT CONTROL SYSTEM (PCS) IN THE

CONTROL SYSTEM CABINET.

THE LEVEL AND FUEL OIL TEMPERATURE OF THE GENERATOR DAY TANKS MUST BE MONITORED AND DISPLAYED AT THE PCS LOCATED IN THE CONTROL

ROOM FOR MONITORING DURING GENERATOR OPERATION. TEMPERATURE SENSORS MUST COMMUNICATE WITH THE PCS TO CONTROL THE

TEMPERATURE LEAVING THE RETURN FUEL OIL COOLER. IF FUEL TEMPERATURE IN THE DAY TANK OF THE AFFECTED GENERATOR EXCEEDS 65 DEGREES

C, THE PCS MUST GO INTO ALARM AND ALERT PERSONNEL OF AN ISSUE WITH THE TEMPERATURE OF THE FUEL IN THE DAY TANK. IF THE TEMPERATURE

CONTINUES TO CLIMB TO 76 DEGREES C, THE EFFECTED GENERATOR MUST BE TAKEN OFFLINE AND PLACED IN COOL DOWN MODE AND SHUT DOWN.

DURING PLANT OPERATION, THE INDIVIDUAL GENERATOR DAY TANK FILL VALVE OPENS WHEN THE TANK IS 50% OF CAPACITY (LOW NORMAL) AND

CLOSES WHEN THE DAY TANK IS 90% OF FULL CAPACITY (HIGH NORMAL) USING DAY TANK LEVEL TRANSMITTER. FILL VALVE MUST HAVE FEEDBACK ON

POSITION TO THE PCS. IF THE VALVE FEEDBACK IS NOT IN THE POSITION OF OPEN AN ALARM MUST BE SENT TO THE PCS AND APPROPRIATE ACTION

MUST BE REQUIRED SUCH AS MANUALLY OPEN THE FILL VALVE OR PLACE GENERATOR IN SHUTDOWN MODE.

IF THE FUEL LEVEL REACHES LOW-LOW LEVEL CONDITION OF 20% CAPACITY THE LOW-LOW-LEVEL ALARM MUST BE SENT TO THE PCS TO ALERT

PERSONNEL ABOUT THE LOW-LOW-LEVEL FUEL CONDITION BY THE LEVEL SWITCH. A GENERATOR IN STANDBY MODE MUST BE COMMANDED TO

INITIALIZE START SEQUENCE, AND THE EFFECTED LOW-LOW LEVEL GENERATOR/DAY TANK MUST INITIATE THE SHUTDOWN SEQUENCE AFTER THE

INITIALIZED GENERATOR IS IN OPERATION AND IS SUPPLYING POWER TO THE BUS. OPERATING PERSONNEL MUST COMMENCE INVESTIGATION OF THE

FUEL INLET VALVE AND ASSOCIATED CONTROLS AS TO THE REASON FOR THE FAILURE OF DAY TANK FUEL LEVEL CONTROL.

DURING PLANT OPERATION IF THE HIGH-HIGH-LEVEL CONDITION ALARM IS TRIGGERED AT 95% OF FULL DAY TANK CAPACITY, THE HIGH-HIGH LEVEL

ALARM SWITCH MUST SEND AN ALARM TO THE PCS TO ALERT PERSONNEL ABOUT THE HIGH-HIGH LEVEL CONDITION AND THE POSSIBLE OVERFILLING

OF THE DAY TANKS. THE OPERATING PERSONNEL MUST MANUALLY CLOSE THE MOTORIZED DAY TANK FILL VALVE TO STOP THE FLOW OF FUEL. IF THE

MOTORIZED FILL VALVE OR ASSOCIATED CONTROLS ARE NOT CORRECTED A MANUAL COMMAND AT THE HMI TO START A GENERATOR IN STANDBY

MODE MUST BE COMMANDED TO INITIALIZE START SEQUENCE. ONCE THE REPLACEMENT GENERATOR IS UP AND RUNNING AND ELECTRICALLY

CONNECTED TO THE BUS, STAFF MUST MANUALLY INITIATE SHUTDOWN OF THE EFFECTED HIGH-HIGH LEVEL GENERATOR/DAY TANK TO START

SHUTDOWN SEQUENCE.

IF FUEL FLOW IS SENSED AT THE ANY DAY TANK OVERFLOW METER FLOW, AN ALARM MUST BE INITIATED TO ALERT THE STAFF THAT A GENERATOR DAY

TANK IS OVERFILLING AND THE DAY TANK MOTORIZED FUEL FILL VALVE WILL NEED TO BE MANUALLY CLOSED AND INVESTIGATED ON THE CAUSE OF

FUEL ENTERING THE FUEL OVERFLOW TANK. IF NECESSARY, ANOTHER GENERATOR MAY NEED TO BE STARTED TO REPLACE THE EFFECTED GENERATOR

THROUGH THE HMI (PCS).

WHEN THE DAY TANK OVERFLOW METER REGISTERS FUEL FLOWING, A STOP COMMAND MUST BE INITIALIZED TO THE BULK STORAGE SUPPLY PUMPS

(FOSP- 01/02) AND REMAIN IN OFF POSITION AS LONG AS FUEL IS BEING SENSED COMING FROM A DAY TANK. THE TIME TO CORRECT THIS SITUATION

IS APPROXIMATELY 4 TO 5 HOURS DUE TO THE STORED FUEL IN THE DAY TANKS AND CIRCULATION SYSTEM. WHEN THE FLOW CONDITION AT THE

OVERFLOW METER SENSES “NO FLOW” A DELAY TIME PERIOD OF 15 MINUTES WILL BE INITIALIZED BEFORE THE STOP COMMAND AT THE BULK

STORAGE SUPPLY PUMPS WILL BE LIFTED. AFTER 15 MINUTES OF “NO FLOW CONDITION” AUTOMATIC CONTROL MUST BE TRANSFERRED TO THE

PRESSURE SENSOR ON THE BLADDER TANK INSIDE THE PLANT TO NORMALLY CONTROL THE BULK STORAGE SUPPLY PUMPS. THE INLET VALVE TO THE

PLANT MUST BE OPENED TO SUPPLY FUEL TO THE FUEL CIRCULATION SYSTEM. THE BULK STORAGE SUPPLY PUMPS WILL ONLY START WHEN FEED BACK

THAT THE INLET VALVE TO THE PLANT (NORTH OR SOUTH) IS OPENED AND THE PLANT CAN RESUME NORMAL OPERATIONS.

IF ANY GENERATOR IS COMMANDED TO START ON THE NORTH OR SOUTH SIDE OF THE PLANT, THE PCS MUST START A FUEL OIL CIRCULATION PUMP

(FOCP 1 THRU 4) ASSOCIATED WITH THE SIDE THE COMMANDED GENERATOR IS LOCATED. EACH SIDE OF THE PLANT HAS A SEPARATE FUEL OIL

CIRCULATION/SUPPLY SYSTEM AND DEPENDING ON WHICH GENERATOR RECEIVES A START COMMAND, THE ASSOCIATED FUEL OIL CIRCULATION PUMP

MUST START. WHEN NO OTHER GENERATORS ARE RUNNING EITHER ON THE NORTH OR THE SOUTH SIDE OF THE PLANT, THE PCS MUST

AUTOMATICALLY START A FUEL OIL CIRCULATION PUMP (FOCP 1 THRU 4) TO MAINTAIN CIRCULATION/PRESSURE ON THE FUEL HEADER (NORTH OR

SOUTH SIDE SYSTEM) USING A PRESET FUEL OIL BACKPRESSURE REGULATOR SET AT 140 kPa.

IF A FUEL OIL SYSTEM PUMP FAILS TO REGISTER A “START” CONDITION WHEN COMMANDED TO START, AN ALARM MUST BE SENT TO THE PCS AND

ALERT STAFF OF A FUEL OIL SYSTEM PUMP FAILURE. THE AFFECTED FUEL OIL SYSTEM PUMP INLET AND OUTLET VALVES MUST CLOSE AND THE

STANDBY FUEL OIL SYSTEM PUMP INLET AND OUTLET VALVES MUST OPEN. WHEN CONFIRMATION OF THE STANDBY PUMP INLET AND OUTLET VALVES

ARE OPEN, THE PCS MUST START THE STANDBY PUMP TO MAINTAIN CIRCULATION/PRESSURE IN THE FUEL HEADER (NORTH OR SOUTH) OF THE PLANT.

IF DURING PUMP CHANGE OVER ANY OF THE AUTOMATIC ISOLATION VALVES FAIL TO REGISTER “OPEN” OR “CLOSE” AN ALARM MUST BE SENT TO THE

PCS TO ALERT STAFF OF A POSSIBLE VALVE FAILURE. THE PCS MUST ALERT AND FLAG WHAT VALVE HAS FAILED AND OPERATION PERSONNEL MUST

HAVE TO EITHER MANUALLY OPERATE THE VALVE OR THE AFFECTED PUMP SYSTEM MUST BE PLACED IN “OUT OF SERVICE” IN THE PCS. WHEN THE PCS

REGISTERS VALVES ARE FULLY OPEN, THE PCS MUST START THE PUMP. STAFF MUST VISUALLY VERIFY IF ONE OF THE CIRCULATION PUMPS ARE IN

OPERATION AND CONFIRM IN THE PCS THAT THE PUMP IS IN OPERATION.

IF BOTH PRIMARY AND SECONDARY PUMPS ARE NOT IN OPERATION, THE DAY TANKS HAVE ABOUT 4 HOURS OF FUEL TO CORRECT THE ISSUE OR THE

AFFECTED SIDE OF THE PLANT (NORTH OR SOUTH) MUST BE PLACED IN SHUTDOWN MODE UNTIL FUEL CIRCULATION PUMPS ARE CORRECTED AND

PLACED BACK INTO SERVICE. IF THERE IS A CONTROL PROBLEM, THE CIRCULATION FUEL OIL PUMPS AND MOTORIZED ISOLATION VALVES CAN BE

OPERATED MANUALLY TO KEEP THE PLANT IN OPERATION. EACH ALARM MUST BE MANUALLY CLEARED THROUGH THE HMI (PCS).

THE PCS MUST CONTINUALLY MONITOR THE CONDITION OF THE FUEL IN THE HEADER AND THE DAY TANKS. IF THE FUEL TEMPERATURE GOES OVER

THE FLASH POINT OF THE NO. 2 DIESEL FUEL (51 DEG C), AN ALARM MUST BE SENT TO THE PCS AND IMMEDIATE CORRECTIVE ACTION MUST BE

NEEDED. IF THE SITUATION CAN NOT BE CORRECTED, THE SIDE OF THE PLANT (OR THE GENERATOR/DAY TANK) EFFECTED MUST NEED TO BE SHUT

DOWN UNTIL CORRECTED.

PCS MUST ALSO MONITOR IF SUPPLY PRESSURE IN THE FUEL OIL CIRCULATION SYSTEM AND IF THE PRESSURE GOES BELOW 50 kPa, AN ALARM MUST BE

SENT TO THE PCS AND THE SECONDARY FUEL OIL CIRCULATION PUMP MUST BE STARTED AND THE PRIMARY CIRCULATION PUMP MUST BE SHUT DOWN

FOR REPAIRS. IF PRESSURE IN THE FUEL OIL CIRCULATION HEADER IS NOT CORRECTED STAFF MUST NEED TO INVESTIGATE THE BACK PRESSURE

REGULATING VALVE TO VERIFY IF THERE IS AN ISSUE AND THE BYPASS VALVE MUST BE USED TO REGULATE BACK PRESSURE MANUALLY IF THE CAUSE IS

THE BACK PRESSURE REGULATOR.

WHEN PRESSURE IN THE FUEL OIL BLADDER TANK REDUCES TO 70 KPA (SUCTION SIDE OF THE FUEL OIL CIRCULATOR PUMPS) A SIGNAL MUST BE SENT

TO BULK STORAGE FUEL TRANSFER PUMPS TO ENERGIZE AND PUMP UP THE FUEL BLADDER TANKS TO 120 KPA (ADJUSTABLE) OR ¾ FULL. THE PUMPS

AT THE BULK STORAGE TANKS MUST START TO TRANSFER FUEL TO THE FUEL OIL CIRCULATION SYSTEM. WHEN THE FUEL BLADDER TANK PRESSURE

REACHES 120 KPA, THE TRANSFER PUMPS AT THE BULK STORAGE TANKS MUST STOP TRANSFERRING FUEL AND BE PLACED IN STANDBY POSITION. THE

INLET VALVES FOR THE NORTH AND THE SOUTH PLANTS MUST REMAIN OPEN DURING GENERATORS OPERATING ON THAT SIDE (NORTH OR SOUTH

PLANT) UNTIL THE LAST GENERATOR IS PLACED IN THE STANDBY MODE (NORTH OR SOUTH SIDE OF PLANT). IF THE PRESSURE SENSOR AT THE BLADDER

TANK SENSES A PRESSURE AT OR BELOW 30 KPA, AN ALARM OF “LOW SUPPLY PRESSURE” WILL ALERT STAFF TO DETERMINE WHY THE BULK STORAGE

FUEL PUMPS OR NOT MAINTAINING FUEL PRESSURE IN THE BLADDER TANK. IF THE FUEL HEADER PRESSURE REGISTERS 70 KPA, THE PLANT CONTROL

SYSTEM WILL ALARM “HEADER PRESSURE LOW”. IF THE HEADER PRESSURE CONTINUES TO DROP TO 40 KPA, AN ALARM WILL SOUND AND ALERT STAFF

THAT THE HEADER CIRCULATION PUMPS WILL BE SHUTTING DOWN TO AVOID DRY RUNNING THE PUMPS.

THE GENERATOR FUEL OIL DAY TANKS MUST HAVE FOUR LEVELS THAT THE PCS MUST MONITOR: HIGH-HIGH, HIGH, LOW, AND LOW-LOW FUEL LEVELS

AS WELL AS AN ACTIVE LEVEL TRANSMITTER SHOWING FUEL LEVEL IN MM AND LITERS. THE LOW AND HIGH LEVELS ARE OPERATIONAL LEVELS AND

MUST BE MONITORED BY THE LEVEL TRANSMITTER. THE LOW AND HIGH LEVELS MUST NOT BE ASSOCIATED WITH AN ALARM. THE LOW-LOW AND

HIGH-HIGH LEVELS MUST NICTITATE AN ALARM AND MUST BE MONITORED BY SEPARATE LEVEL SWITCHES.

HIGH-HIGH LEVEL ALARM:

WHEN AN INDIVIDUAL GENERATOR DAY TANK REGISTERS 95% (ADJ) FULL THE PCS MUST INITIATE AN HIGH-HIGH LEVEL CONDITION ALARM TO ALERT

STAFF OF A DAY TANK IN A POSSIBLE OVERFILL CONDITION.

HIGH-LEVEL (OPERATIONAL):

WHEN FUEL REACHES 90% FULL IN ANY GENERATOR DAY TANK THE PCS MUST CLOSE THE ASSOCIATED FILL VALVE TO MAINTAIN NORMAL OPERATING

LEVELS BETWEEN 50% (ADJ) AND 90% (ADJ) OF GENERATOR DAY TANK CAPACITY.

LOW-LEVEL (OPERATIONAL):

WHEN FUEL REACHES 50% FULL IN ANY GENERATOR DAY TANK THE PCS MUST OPEN THE ASSOCIATED FILL VALVE TO MAINTAIN NORMAL OPERATING

LEVELS BETWEEN 50% (ADJ) AND 90% (ADJ) OF GENERATOR DAY TANK CAPACITY.

LOW-LOW-LEVEL ALARM:

WHEN ANY GENERATOR DAY TANK REGISTERS A LOW-LOW LEVEL AT 20% (ADJ), THE PCS MUST INITIATE AN LOW-LOW LEVEL CONDITION ALARM AND

MUST ALERT PERSONNEL OF A LOW FUEL LEVEL IN AN INDIVIDUAL DAY TANK. THIS CONDITION MUST BE INVESTIGATED TO DETERMINE CAUSE OF THE

LOW-LOW LEVEL CONDITION BEFORE THE GENERATOR MUST GOES INTO SHUT DOWN MODE.

DIESEL EXHAUST FLUID (DEF) SEQUENCES OF OPERATION

DEF DELIVERY SYSTEM

GENERAL NOTE: WHERE SEQUENCE INDICATES A VALVE TO OPEN OR CLOSE, INFER VALVE MUST BE "COMMANDED AND VERIFIED" OPEN OR CLOSED.

NOTE: LEVEL AND TEMPERATURE SHUTDOWN ALARMS MUST ALL BE HARD WIRED AND PROGRAMMED IN THE PLANT CONTROL SYSTEM (PCS) IN THE

CONTROL SYSTEM CABINET.

ON START COMMAND FROM ANY GENERATOR, THE PCS MUST SELECT A DEF TANK TO ALIGN. GENERATOR/GENERATORS BEING STARTED MUST SIGNAL

THE PCS THRU THE DOSING CABINETS ASSOCIATED WITH EACH GENERATOR.

NOTE: THE ASSOCIATED COMPRESSED AIR SYSTEM SERVING THE DEF DOSING CABINET MUST OPERATE AUTONOMOUSLY AND MAINTAIN PRESSURE IN

THE COMPRESSED AIR RECEIVER CONTINUOUSLY. IF THERE IS A FAILURE OR A LOSS OF PRESSURE, THE PCS MUST RECEIVE AN ALARM AND THAT

GENERATOR MUST BE TAKEN OUT OF SERVICE. REFER TO COMPRESSED AIR SECTION FOR DETAILED SEQUENCE AND COMPRESSED AIR GENERATOR

START.

WHEN INITIALIZING THE DEF SYSTEM, THE PCS MUST SELECT THE BEST DEF TANK TO ALIGN TO THE DEF CIRCULATION SYSTEM. THE PCS MUST CHECK

ALL TANK LEVELS AND MUST SELECT A TANK WITH A LEVEL GREATER THAN 75% FULL (ADJ.). IF MORE THAN ONE TANK HAS OVER 75% CAPACITY OF

DEF, THEN THE NEXT SEQUENTIAL FULL DEF TANK (FROM THE LAST START) MUST BE SELECTED TO SUPPORT GENERATOR OPERATION. IF NO DEF TANK

IS OVER 75% THEN THE DEF TANK WITH THE HIGHEST LEVEL MUST BE SELECTED.

WHEN A DEF TANK IS SELECTED, THE DEF TANK OUTLET VALVE MUST BE COMMANDED OPEN. IF THE PCS REGISTERS A FEEDBACK ALARM FROM THE

DEF TANK OUTLET VALVE NOT FULLY OPEN, AN ALERT MESSAGE MUST BE DISPLAYED ON THE PCS HMI, " FAILURE OF CONFIRMATION OF DEF TANK ##

OUTLET VALVE OPENED TO SYSTEM". PCS MUST ATTEMPT TO CLOSE THE EFFECTED TANK OUTLET VALVE, PLACE THE AFFECTED DEF TANK IN “OUT OF

SERVICE” CONDITION UNTIL VALVE IS REPAIRED OR MANUALLY OPENED. IF THE VALVE IS MANUALLY OPENED, THE ALARM CAN BE CLEARED MANUALLY

AT THE HMI/PCS. WHEN THE REPAIRS ARE COMPLETE, THE ALARM CAN BE CLEARED AT AN HMI BY SELECTING “CLEAR ALARM”. THE PCS MUST

INITIALIZE THE NEXT SEQUENTIAL TANK FROM THE PREVIOUS TANK SELECTION SEQUENCE.

THE PCS MUST INITIATE A DEF CIRCULATION PUMP (DEFP-01, DEFP-02) TO START BY ROTATING THE START FROM THE LAST INITIALIZATION OF THE DEF

SYSTEM. THE PCS MUST DESIGNATE EACH PUMP AS LEAD AND LAG WHEN PLACED IN OPERATION. THE LEAD DEF PUMP INLET AND OUTLET VALVES

MUST BE COMMANDED OPEN WITH VERIFICATION FEEDBACK OF THE VALVE FULLY OPENED. ONCE THE INLET AND OUTLET VALVES ARE VERIFIED OPEN

THROUGH THE PCS, THE LEAD DEF PUMP MUST START. PCS MUST RECEIVE A VERIFICATION SIGNAL THAT THE PUMP HAS STARTED AND IS OPERATING

WITHIN PARAMETERS. VERIFICATION OF DEF FLOW MUST ALSO BE REGISTERED NEAR THE BACK PRESSURE REGULATOR BY THE FLOW SENSOR AND THE

DEF HEADER PRESSURE TRANSMITTER. A SIGNAL FROM THE PCS MUST BE SENT TO THE GENERATOR/GENERATORS THAT THE DEF SYSTEM IS

OPERATING AND MUST BE DESIGNATED AS ONE OF THE PERMISSIVES FOR STARTING THE GENERATOR/GENERATORS.

IF DURING START UP OF THE DEF PUMPS, THE LEAD PUMP VALVES DO NOT SHOW FULLY OPENED POSITION OR THE LEAD PUMP FAILS TO START, THE

LEAD PUMP VALVES MUST BE COMMANDED CLOSED AND THE LEAD DEF PUMP PLACED IN “OUT OF SERVICE” AND THE LAG DEF PUMP MUST BE

INITIALIZED AND FOLLOW THE SAME PREVIOUS DEF PUMP START SEQUENCE.

WHEN THE DEF CIRCULATION SYSTEM IS ACTIVATED, THE HEADER PRESSURE MUST BE MAINTAINED AT 35 KPA BY A MANUALLY SET BACK-PRESSURE

REGULATOR. THE PCS MUST RECEIVE FLOW AND PRESSURE VERIFICATION AND MUST RELEASE GENERATOR START COMMANDS AT THE MAIN

GENERATOR CONTROL SYSTEM AND MUST SEND A SIGNAL TO ALERT PERSONNEL THAT THE DEF SYSTEM IS ACTIVE AND OPERATING NORMALLY. AS

EACH GENERATOR IS COMMANDED TO START, THE DEF INLET VALVE TO THE DOSING STATION MUST BE COMMANDED OPEN.

AS EACH DEF STORAGE TANK IS DRAWN DOWN TO 10% (ADJ.) A SIGNAL BACK TO THE PCS THAT THE NEXT DEF BULK STORAGE TANK MUST BE

INITIALIZED AND ORIGINAL TANK BE PLACED IN “LOW CONDITION OUT OF SERVICE”. PCS CHECKS THE LEVEL OF THE NEXT HIGHEST LEVEL SEQUENTIAL

DEF BULK STORAGE TANK AND VERIFIES IT HAS ADEQUATE STORAGE CAPACITY TO BE PLACED INTO SERVICE (ABOVE 10% OF TANK CAPACITY). ONCE

THE PCS HAS SELECTED THE NEXT DEF BULK STORAGE TANK TO BE ALIGNED, THE DESIGNATED NEXT DEF TANK OUTLET VALVE MUST BE COMMANDED

OPEN. IF FAILURE TO OPEN THE NEXT DEF TANK OUTLET VALVE, THE PCS MUST PLACE THAT TANK IN “FAILURE OUT OF SERVICE” AND THE NEXT

SEQUENTIAL TANK MUST BE SELECTED AND THE OUTLET VALVE OPENED. ANY FAILURES MUST HAVE TO BE REPAIRED AND MANUALLY CLEARED AT THE

MAIN PCS HMI.

WHEN NEXT SEQUENTIAL TANK IS ALIGNED TO THE DEF CIRCULATION SYSTEM, THE DEPLETED DEF TANK OUTLET VALVE MUST BE COMMANDED TO

CLOSE. WHEN THE LAST GENERATOR IN THE PLANT (NORTH AND SOUTH) SHUT DOWN AND ALL GENERATOR OPERATIONS ARE OVER, A SIGNAL FROM

THE REMAINING ACTIVE GENERATOR CONTROLLER MUST SIGNAL THE PCS TO SHUTDOWN THE DEF SYSTEM. WHEN THE STOP COMMAND IS ISSUED TO

ANY GENERATOR THE INLET VALVE TO THE ASSOCIATED DOSING STATION MUST CLOSE AND SIGNAL THE PCS THAT IT IS IN THE CLOSED POSITION. IF

FEEDBACK IS NOT RECEIVED THAT THE VALVE IS IN THE CLOSED POSITION, AN ALARM MUST BE SENT TO THE PCS TO ALERT THE PERSONNEL OF A

POSSIBLE VALVE FAILURE AND MUST BE CLEARED AT THE MAIN PCS HMI.

THE PCS MUST KEEP THE DEF PUMP CIRCULATING FOR 1 HOUR (ADJ.) AFTER THE LAST GENERATOR IS STOPPED. AFTER 1 HOUR THE PCS MUST SEND A

COMMAND TO STOP THE ACTIVE DEF CIRCULATION PUMP AND CLOSE THE INLET AND OUTLET VALVES. THE PCS MUST ALSO CLOSE THE DEF TANK

OUTLET VALVE THAT WAS ALIGNED TO THE SYSTEM.

IF DURING GENERATOR OPERATIONS AND THE DEF SYSTEM IS ON THE LAST FULL STORAGE TANK, AN ALARM MUST BE SENT TO THE PCS TO ALERT

OPERATIONAL PERSONNEL THAT DEF STORAGE CAPACITY IS LOW AND DEF IS NEEDED FOR DELIVERY.

DURING GENERATOR OPERATIONS, IF THE FLOW METER IN THE DEF CIRCULATION HEADER REGISTERS “NO FLOW”AND THE LEAD DEF PUMP HAS

FEEDBACK SHOWING IT IS IN “ON” STATUS, THE PCS MUST SEND AN ALARM OF A “DEF CIRCULATION PUMP FAILURE”. THE PCS REMOVE POWER TO

THE LEAD PUMP AND CLOSE INLET AND OUTLET VALVES. THE PCS MUST COMMAND THE LAG PUMP INLET AND OUTLET VALVE OPEN AND FEEDBACK

MUST CONFIRM VALVE POSITION. WHEN POSITIVE FEEDBACK IS RECEIVED VALVES ARE IN THE COMMANDED POSITION, THE LAG DEF CIRCULATION

PUMP MUST BE STARTED. ALARM MUST BE CLEARED ONCE FLOW IS VERIFIED AT DEF CIRCULATION HEADER FLOW METER.

DEF FILL AND TRANSFER OPERATING PROCEDURE

DEF FILL SYSTEM

GENERAL NOTE: WHERE SEQUENCE INDICATES A VALVE TO OPEN OR CLOSE, INFER VALVE MUST BE "COMMANDED AND VERIFIED" OPEN OR CLOSED.

NOTE: LEVEL AND TEMPERATURE SHUTDOWN ALARMS MUST ALL BE HARD WIRED AND PROGRAMMED IN THE PLANT CONTROL SYSTEM (PCS) IN THE

CONTROL SYSTEM CABINET.

WHEN DEF IS NEEDED TO FILL DEF STORAGE TANK, THE EXTERIOR CONTROL CABINET MUST BE OPENED AND THE OPERATOR MUST THE TANKER HOSE

TO THE CAM LOCK FITTING. ON THE EXTERIOR DEF CONTROL PANEL, SELECT THE TANK TO BE FILLED. WHEN A DEF BULK STORAGE TANK IS SELECTED

TO FILL, SYSTEM FILL VALVE AND TANK INLET VALVE MUST BE COMMANDED OPEN WITH FEEDBACK POSITION SIGNAL TO THE PCS. THE EXTERIOR HMI

SCREEN MUST INDICATE A FEEDBACK VALVES ARE FULLY OPEN AND THE DEF BULK STORAGE TANK IS READY TO RECEIVE DIESEL EXHAUST FLUID BEFORE

FILLING OPERATIONS CAN BEGIN.

WHEN FILLING OPERATIONS ARE READY TO START, STAFF AT THE PCS/HMI MUST SELECT TO OPEN FILL/TRANSFER CROSS CONNECT VALVE, DEFP 03

PUMP INLET AND OUTLET VALVES. WHEN THE PCS REGISTERS THE VALVES ARE OPEN, THE TRANSFER PUMP MUST BE ALLOWED TO BE STARTED.

OPERATIONAL PERSONNEL MUST THEN START THE FILL/TRANSFER PUMP DEFP 03, TO FILL SELECTED TANK FROM THE DEF DELIVERY TRUCK. IF ANY OF

THE VALVES FAIL TO REGISTER OPEN, THE FILL/TRANSFER PUMP DEFP 03 MUST REMAIN IN THE “OFF” POSITION UNTIL MANUALLY OPENED OR REPAIRS

HAVE BEEN COMPLETED.

IF THERE IS A FAILURE (THE SYSTEM FILL VALVE OR INLET VALVE) OF FEEDBACK AN ALARM BACK TO THE EXTERIOR HMI AND THE PCS MUST

REGISTER,"FAILURE OF CONFIRMATION OF VALVE OPEN TO SYSTEM" MUST ALERT PERSONNEL AND ON THE HMI THE VALVE WITH THE FAILURE MUST

BE INDICATED. ANOTHER TANK SELECTION MUST BE MADE TO FILL, OR MANUAL MANIPULATION OF THE MOTORIZED VALVE USING THE HAND WHEEL

ON THE VALVE. WHEN THE LEVEL INDICATOR LOCALLY OR THRU THE PCS HAS ESTABLISHED THAT THE DEF TANK IS AT 90% FULL, A WARNING MESSAGE

MUST BE ON THE HMI TO ALERT THE STAFF TO STOP FILLING THE ALIGNED TANK AND SELECT ANOTHER TANK OR SHUT DOWN DEF FILLING

OPERATIONS.

IF ANOTHER TANK IN THE DEF TANK STORAGE ROOM REQUIRES DEF, THE FILL/TRANSFER PUMP MUST NEED TO BE MANUALLY STOPPED BY SELECTING

“OFF” ON THE PCS/HMI. STAFF MUST MAKE ANOTHER TANK SELECTION AND THE PCS MUST START ALIGNING THE NEXT TANK TO FILL.

WITH THE DEF SYSTEM FILL VALVE IN THE "OPEN" POSITION DUE TO THE FILLING OPERATIONS, THE NEXT TANK INLET VALVE MUST BE SWITCHED TO

THE "OPEN" POSITION. FEEDBACK THAT THE VALVE IS IN THE OPEN POSITION MUST REGISTER ON THE PCS/HMI BY SHOWING THAT THE VALVE IS

CONFIRMED IN THE OPEN POSITION. AFTER POSITIVE FEEDBACK THAT THE NEXT TANK INLET VALVE IS "OPEN", THE PREVIOUS TANK INLET VALVE MUST

BE CLOSED BY THE PCS. WHEN POSITIVE FEEDBACK VALVE IS "CLOSED" THROUGH THE PCS/HMI, STAFF MUST RESUME FILLING OPERATION TO THE

SELECTED TANK. SELECTION FOR ALL THE SUBSEQUENT TANKS MUST BE COMPLETED WITH THE SAME METHODOLOGY UNTIL ALL TANKS ARE AT THE

90% LEVEL.

WHEN DEF FILL OPERATIONS ARE COMPLETE, STAFF MUST STOP THE FILL/TRANSFER PUMP PLACE IT IN THE “OFF” POSITION. STAFF MUST SELECT TO

STOP FILLING OPERATIONS FROM THE PCS/HMI AND THE PCS MUST CLOSE THE DEF SYSTEM INLET VALVE AND PUMP DEFP 03 INLET AND OUTLET

VALVES. WITH CONFIRMATION THAT ALL VALVES ARE CLOSED THROUGH THE PCS/HMI THE HMI MUST DISPLAY A TIME CLOCK OF 2-MINUTE DELAY

(ADJ.) TO ALLOW ANY DEF TO DRAIN TO A TANK. WHEN THE TIME DELAY IS COMPLETE THE PCS MUST CLOSE THE LAST TANK INLET VALVE. THE

PCS/HMI MUST REGISTER POSITIVE FEEDBACK THAT THE TANK INLET VALVE IS CLOSED, PERSONNEL MUST CLOSE THE MANUAL CAM LOCK VALVE IN THE

FILL CABINET AND THE VALVE ON THE DELIVERY TRUCK. STAFF MUST REMOVE THE HOSE AND CAP THE HOSE AND THE CAM LOCK IN THE CABINET. ANY

RESIDUAL DEF MUST BE CAPTURED AND PROPERLY DISPOSED OF IN ACCORDANCE WITH DOD REQUIREMENTS.

IF FAILURE OF FEEDBACK POSITION “CLOSED” FROM SYSTEM FILL VALVE OR THE TANK INLET VALVE, THE FOLLOWING ALARMS WILL BE DISPLAYED ON

THE PCS/HMI, " FAILURE OF CONFIRMATION OF SYSTEM FILL VALVE FULLY CLOSED" OR “FAILURE OF CONFIRMATION OF TANK INLET VALVE CLOSED”. IF

THERE IS A FAILURE FEEDBACK FROM A VALVE WHEN SECURING FROM FILLING OPERATIONS, THE STAFF MUST HAVE TO MANUALLY CLOSE THE FAILED

VALVES AND CONFIRM VISUALLY AND/OR THRU THE PCS THAT THE VALVE IS POSITIVELY CLOSED BEFORE THE FILL HOSE IS REMOVED. THE FAILED

VALVE MUST NEED TO BE REPAIRED BEFORE THE NEXT FILL OPERATIONS CAN TAKE PLACE.

TO TRANSFER DEF FROM ONE TANK TO ANOTHER, THRU THE PCS/HMI, STAFF MUST SELECT “TRANSFER” AND THE PCS MUST DIRECT STAFF TO SELECT

THE TANK “TO AND FROM” TO TRANSFER DEF FROM ONE TANK TO ANOTHER. THE PCS MUST OPEN THE “FROM TANK” OUTLET VALVE AND THE “TO

TANK” FILL VALVE. ALSO, THE INLET AND OUTLET VALVES FOR PUMP DEFP 03 MUST OPEN BY THE PCS. ONCE POSITIVE FEEDBACK FROM ALL VALVES

ARE OPEN, THE DEFP 03 FILL/TRANSFER PUMP MUST BE ENABLED TO BE STARTED BY THE STAFF OPERATOR. THE STAFF MUST START THE PUMP FOR

TRANSFER.

WHEN TRANSFER OPERATIONS ARE COMPLETED, THE SELECTION TO STOP TRANSFER MUST BE INITIALIZED ON THE PCS/HMI AND THE PCS MUST STOP

THE PUMP DEFP 03. AFTER CONFIRMATION OF PUMP IN THE OFF POSITION, STAFF OPERATOR MUST SELECT TO “SECURE FROM TRANSFER” AND THE

PCS MUST CLOSE ALL OPEN VALVES EXCEPT FOR THE FILL TANK INLET. AFTER 2 MINUTE TIMER DELAY THE FILL VALVE MUST CLOSE. IF ANY VALVE DOES

NOT HAVE POSITIVE FEEDBACK OF VALVES CLOSED THE PCS MUST BE IN ALARM FOR VALVE FAILURE.

COMPRESSED AIR SYSTEM OPERATING PROCEDURE

GENERAL NOTE: WHERE SEQUENCE INDICATES A VALVE TO OPEN OR CLOSE, INFER VALVE SHALL BE "COMMANDED AND VERIFIED" OPEN OR CLOSED.

NOTE: LEVEL AND TEMPERATURE SHUTDOWN ALARMS MUST ALL BE HARD WIRED AND PROGRAMMED IN THE PLANT CONTROL SYSTEM (PCS) IN THE

CONTROL SYSTEM CABINET.

COMPRESSED AIR SYSTEM MUST BE AUTONOMOUS AND MUST MAINTAIN WORKING PRESSURE 1273 KPA THRU THE COMPRESSED AIR DRYER AND

STORED IN THE 1893 LITER RECEIVER. SEPARATE ENGINE START, AIR FILTER CLEANING, DIVERTER VALVE AND OTHER USERS MUST BE PROVIDED WITH

PRESSURE REGULATORS TO ENSURE APPROPRIATE PRESSURE AIR IS PROVIDED TO EACH PIECE OF EQUIPMENT USING COMPRESSED AIR.

DURING INITIAL START THE SELECTOR SWITCH MUST BE PUT INTO THE “AUTOMATIC” POSITION AND THE PCS MUST ONLY MONITOR THE COMPRESSED

AIR SKID FOR EACH GENERATOR. IF THE PRESSURE REGISTERS A MINIMUM PRESSURE OF 650 KPA A HORN/STROBE ALARM ACTIVATE AT THE

COMPRESSED AIR SKID AND MUST ALSO ALARM TO THE PCS TO ALERT PERSONNELTHAT “COMPRESSED AIR FOR START UP IS NOT AVAILABLE” FOR THIS

GENERATOR AND MUST BE PLACED OUT OF SERVICE. REPAIRS MUST HAVE TO BE COMPLETED AND MANUALLY RESET AT THE PCS/HMI IS REQUIRED TO

PLACE THIS EQUIPMENT/GENERATOR BACK INTO SERVICE.

A HIGH-PRESSURE ALARM VALUE OF 1250 KPA A HORN/STROBE ALARM MUST ACTIVATE AT THE COMPRESSED AIR SKID AND MUST ALSO SEND AN

ALARM TO THE PCS TO ALERT STAFF OF “OVER PRESSURIZATION IN RECEIVER”. THE PCS MUST DEACTIVATE THE COMPRESSOR AT THE COMPRESSED AIR

SKID. (RELIEF VALVE ON THE RECEIVER TANK MUST BE SET TO 1300 KPA). REPAIRS MUST HAVE TO BE COMPLETED AND A MANUAL RESET AT THE

PCS/HMI IS REQUIRED TO PLACE THIS EQUIPMENT/GENERATOR BACK INTO SERVICE.

STATUS AND CONDITION OF COMPRESSED AIR SKID MUST BE COMMUNICATED TO THE PCS AND MUST ACTIVATE A HORN/STROBE AND SEND THE

ALARM TO THE PCS TO ALERT STAFF THAT “COMPRESSED AIR EQUIPMENT IS IN TROUBLED ALARM” AND MUST NEED TO BE CORRECTED. MANUAL

RESET AT THE PCS/HMI IS REQUIRED TO PLACE THIS EQUIPMENT/GENERATOR BACK INTO SERVICE.

NORMAL OPERATING PROCEDURES: COMPRESSOR MUST ENGAGE WHEN PRESSURE GETS TO 690 KPA AND SHUT OFF AT 1170 KPA WITH PRESSURE

MONITORED BY THE PCS.

GENERATOR COOLING SYSTEM OPERATING PROCEDURE

GENERAL NOTE: WHERE SEQUENCE INDICATES A VALVE TO OPEN OR CLOSE, INFER VALVE SHALL BE "COMMANDED AND VERIFIED" OPEN OR CLOSED.

NOTE: LEVEL AND TEMPERATURE SHUTDOWN ALARMS MUST ALL BE HARD WIRED AND PROGRAMMED IN THE PLANT CONTROL SYSTEM (PCS) IN THE

CONTROL SYSTEM CABINET.

GENERATOR JACKET WATER AND GENERATOR AFTER COOLER/LUBE OIL COOLER COOLING WATER SYSTEM MUST BE ENERGIZED WHEN A MANUAL

START COMMAND IS SENT TO THE ASSOCIATED GENERATOR. THE COOLING WATER SYSTEM ASSOCIATED WITH A SPECIFIC GENERATOR MUST INITIATE

START UP OF THE COOLING PUMPS, RADIATOR FANS AND OPEN ASSOCIATED VALVES.

WHEN A GENERATOR RECEIVES A START COMMAND, THE PCS MUST OPEN INLET AND OUTLET VALVES FOR THE JACKET WATER AND AFTER

COOLER/LUBE OIL COOLER CIRCUIT PUMPS. WHEN CONFIRMATION IS RECEIVED BY THE PCS OF FULLY OPENED VALVES, THE PCS MUST START THE

COOLING WATER PUMPS. WITH THE COOLING WATER PUMPS RUNNING AND CONFIRMATION OF FULL FLOW OF AT LEAST 2800 LPM, THE FAN VFDS

MUST POWER UP TO MINIMUM SPEED OF 30%. ONCE A CONFIRMATION OF A GENERATOR START, THE TEMPERATURE SENSOR IN THE SUPPLY WATER

BACK TO THE GENERATOR MUST FIRST CONTROL THE THREE-WAY TEMPERATURE CONTROL VALVE ON EACH COOLING CIRCUIT. THE THREE-WAY

TEMPERATURE CONTROL VALVE WILL START TO OPEN TO THE REMOTE RADIATOR TO THE LIMIT OF FULLY OPEN FLOW. AS THE TEMPERATURE BEGINS

TO RISE TO SET POINT OF 57 DEGREE C ON THE AFTER-COOLER CIRCUIT ALL THREE FANS ON THE ASSOCIATED REMOTE RADIATOR WILL START TO RAMP

UP TO FULL SPEED. BOTH THREE-WAY TEMPERATURE CONTROL VALVES MUST TRACK TOGETHER AS THE VALVES OPEN TO THE RADIATOR. THE ALL

THREE FANS ON THE RADIATOR MUST ALSO TRACK TOGETHER AS THE FANS RAMP UP. THE AFTER COOLER/LUBE OIL COOLER MUST BE THE CONTROL

TEMPERATURE DUE TO THE CRITICALITY OF THIS CIRCUIT AND MUST MAINTAIN A MINIMUM SUPPLY TEMPERATURE OF 57 DEGREE C BACK TO THE

GENERATOR BY CONTROLLING THE SPEED OF THE FANS AND THE THREE-WAY CONTROL VALVE IN EACH COOLING CIRCUIT.

IN THE EVENT COOLING WATER SUPPLY TEMPERATURE REACHES 65 DEGREE C (ADJ), AN ALARM MUST BE SENT TO THE PCS TO ALERT STAFF, “REMOTE

RADIATORS ARE SUPPLYING COOLING WATER OUT OF TEMPERATURE REQUIREMENTS”. THE ISSUE MUST BE RESOLVED AND MANUALLY RESET THE

ALARM ON THE PCS/HMI. IF ISSUE REMAINS THE ENGINE AFFECTED MUST START TO REDUCE POWER OUTPUT AND THIS COMMAND MUST BE

INITIATED AT THE INDIVIDUAL GENERATOR CONTROLLER.
