%%UGENERAL NOTES:

AutoCAD SHX Text ALL CONTROL FUNCTIONS DESCRIBED ON THIS DRAWING SHALL BE CONTROLLED BY THE PLANT FIELD CONTROL CABINET, CP-5, UNLESS OTHERWISE NOTED. REFER TO DRAWING EP201 FOR LOCATION OF PLANT FIELD CONTROL CABINET CP-5. REFER TO DRAWING MI501 FOR SCHEMATIC REPRESENTATION OF BALANCE OF PLANT CONTROL POINTS.

AutoCAD SHX Text SUPPLY AIR HEATER SAH-1 SHALL OPERATE AT 6,000 CFM AND SHALL BE INTERLOCKED WITH BIOMASS BOILER BLR-4. SUPPLY AIR HEATER SAH-2 SHALL ALSO OPERATE AT 6,000 CFM AND SHALL BE INTERLOCKED WITH BIOMASS BOILER BLR-5. EACH BOILER SHALL NOT COMMENCE START PROCEDURES UNTIL ASSOCIATED SUPPLY AIR HEATER IS PROVEN TO BE IN OPERATION. EACH SUPPLY AIR HEATER PROVIDES THE FULL REQUIRED BOILER COMBUSTION AIR PLUS AN ADDITIONAL 10% EXCESS AIR FOR ROOM OVER-PRESSURIZATION. EACH SUPPLY AIR HEATER SHALL INCLUDE A STEAM HEATING COIL WITH INTERNAL FACE AND BYPASS DAMPER CONTROL. SUPPLY AIR SHALL BE MAINTAINED AT MINIMUM 50 DEGREE F (ADJUSTABLE) LEAVING AIR TEMPERATURE. IN NON-HEAT MODE, STEAM COIL SHALL AUTOMATICALLY BYPASS AIRSTREAM AND MAINTAIN CONSTANT OUTSIDE AIR TEMPERATURE TO PLANT. THE OPERATORS MAY, AT THEIR OPTION, SHUT OFF STEAM COIL FLOW WITH PROVIDED ISOLATION VALVES DURING NON-HEATING REQUIRED MONTHS. SUPPLY AIR FANS (SAF-1, SAF-2, AND SAF-3) SHALL PROVIDE SPACE SUMMER VENTILATION AND SHALL BE INTERLOCKED WITH THE ASSOCIATED ROOF MOUNTED EXHAUST FANS (EF-1, EF-2, AND EF-3) RESPECTIVELY. EACH SUPPLY AIR FAN SHALL BE OPERATED IN MATCHED PAIRS WITH ITS ASSOCIATED EXHAUST FAN. EACH SUPPLY AIR FAN SHALL BE TESTED, ADJUSTED, AND BALANCED (TAB); SAF-1, SAF-2 AND SAF-3 TO 20,000 CFM AIRFLOW RATE BY UTILIZING THE FAN'S VARIABLE SPEED DRIVE FOR APPROPRIATE SPEED CONTROL SETTING. EACH EXHAUST FAN SHALL BE TESTED, ADJUSTED, AND BALANCED (TAB) TO 18,000 CFM AIRFLOW RATE BY UTILIZING THE FAN'S VARIABLE SPEED DRIVE FOR APPROPRIATE SPEED CONTROL SETTING. EACH OPERATING PAIR OF FANS SHALL THEREFORE MAINTAIN A 2,000 CFM OVER-PRESSURIZATION OF THE BOILER PLANT SPACE DURING OPERATION ALLOWING A POSITIVE PRESSURE BOILER PLANT OPERATION. TWO BOILER PLANT SPACE TEMPERATURE SENSORS SHALL BE PROVIDED - ONE AT THE FLOOR LEVEL AND ONE AT THE UPPER CATWALK LEVEL. SHOULD EITHER TEMPERATURE SENSOR REACH AN 85 DEGREE F (ADJUSTABLE) SETPOINT TEMPERATURE, THE FIRST STAGED PAIR OF SUPPLY AIR FAN AND EXHAUST FAN SHALL BE ENGAGED. SHOULD EITHER BOILER PLANT SPACE TEMPERATURE SENSOR CONTINUE TO RISE TO A 90 DEGREE F (ADJUSTABLE) SETPOINT TEMPERATURE, THE SECOND STAGED PAIR OF SUPPLY AIR FAN AND EXHAUST FAN SHALL BE ENGAGED. SHOULD EITHER BOILER PLANT SPACE TEMPERATURE SENSOR CONTINUE TO RISE TO A 95 DEGREE F (ADJUSTABLE) SETPOINT TEMPERATURE, THE THIRD STAGED PAIR OF SUPPLY AIR FAN AND EXHAUST FAN SHALL BE ENGAGED. ONCE ENGAGED ALL FANS SHALL BE OPERATED FOR A MINIMUM 10 MINUTE (ADJUSTABLE) TIME FRAME TO PREVENT EQUIPMENT SHORT CYCLING. IN ADDITION, PROVIDE A MINIMUM 2 DEGREE F ADJUSTABLE DEADBAND SPAN RANGE FOR EACH TEMPERATURE SENSING CONTROL SETPOINT. CONTROL SYSTEM SHALL ROTATE STAGED EQUIPMENT SEQUENCING ON A BI-WEEKLY BASIS SO THAT ALL THREE PAIRED FAN SYSTEMS ARE OPERATED EVENLY. THE ROOFTOP EXHAUST FANS (EF-1, EF-2, EF-3) SHALL INCLUDE MOTOR OPERATED DAMPERS WHICH SHALL BE INTERLOCKED WITH THE OPERATION OF THE FAN. IN ADDITION, THE MOTOR OPERATED DAMPERS SHALL BE MANUALLY OPERABLE AT THE COMPUTER WORKSTATION BY THE OPERATORS FOR NATURAL CONVECTION EXHAUST WITHOUT EXHAUST FAN OPERATION. BATHROOM EXHAUST FAN (EF-5) SHALL BE INTERLOCKED WITH BATHROOM LIGHTS TO ONLY ENGAGE FAN OPERATION DURING USAGE. CIRCULATION FAN (CF-1) SHALL BE OPERATED VIA LOCAL WALL SWITCH TO ASSIST IN AIRFLOW CIRCULATION IN AND AROUND THE STEAM TURBINE GENERATOR AS DEEMED APPROPRIATE BY OPERATIONAL PERSONNEL. EXHAUST FAN (EF-4) SHALL BE CONTROLLED VIA HAND-OFF-AUTO SWITCH. AUTOMATIC MODE SHALL BE INTERLOCKED WITH BUNKER ROLL-UP DOOR OPERATION VIA END SWITCHES. EITHER ROLL-UP DOOR NOT BEING CLOSED SHALL ENGAGE FAN OPERATION. WITH BOTH DOORS CLOSED, FAN SHALL BE DISENGAGED. CONTROL ROOM SHALL HAVE INDICATION OF BUNKER ROLL-UP DOORS OPEN/CLOSED. EUH-1, EUH-2 AND EUH-3 SHALL BE CONTROLLED LOCALLY VIA UNIT MOUNTED , EUH-2 AND EUH-3 SHALL BE CONTROLLED LOCALLY VIA UNIT MOUNTED EUH-2 AND EUH-3 SHALL BE CONTROLLED LOCALLY VIA UNIT MOUNTED AND EUH-3 SHALL BE CONTROLLED LOCALLY VIA UNIT MOUNTED EUH-3 SHALL BE CONTROLLED LOCALLY VIA UNIT MOUNTED SHALL BE CONTROLLED LOCALLY VIA UNIT MOUNTED THERMOSTATS. ELECTRIC UNIT HEATERS TO BE USED ONLY IN EMERGENCY CONDITIONS WHEN BOILERS ARE NOT OPERATING.
