GENERATOR/LOUVER INTERFACE REQUIREMENTS

PROVIDE LOUVER AND GENERATOR ACCESSORIES AS REQUIRED TO ACCOMPLISH THESE CON-

TROLACTIONS:

1. THE LOUVER IS TO BE ELECTRICALLY HELD CLOSED AND SPRINGS OPEN UPON LOSS OF 120

VAC POWER TO THE LOUVER SPRING RELEASE MECHANISM. A RELAY MUST BE USED TO DROP

POWER TO LOUVER RELEASE MECHANISM UPON GENERATOR RECEIPT OF A START SIGNAL.

2. THE LOUVER MUST BE PROVED OPEN BEFORE THE GENERATOR STARTS.

3. THE LOUVER IS HELD OPEN AFTER THE STOP SIGNAL IS SENT TO THE GENERATOR AND THE

GENERATOR CONTINUES TO RUN DURING THE COOL DOWN MODE AND AFTER COOL DOWN AND

THE GENERATOR IS SHUT DOWN, THE LOUVER IS THEN CLOSED.

4. THE LOUVER HELD CLOSE SIGNAL IS ROUTED THROUGH THE GENERATOR START AND/OR

RUN RELAY SO THAT THE GENERATOR CAN BE TESTED WITH LOUVER OPERATION EVEN

THOUGH UTILITY POWER IS PRESENT.

GENERALLY THE LOUVER SHOULD HAVE SOME VERSION OF AN END SWITCH TO PROVE THE

LOUVER IS OPEN. THE LOUVER CLOSE MOTOR IS POWERED THROUGH THE GENERATOR RUN

RELAY. THE LOUVER TRIP TO OPEN SIGNAL (LACK OF VOLTAGE ON SPRING ACTUATOR) IS

ROUTED THROUGH THE GENERATOR CONTROLS SO THAT THE LOUVER CAN BE OPENED DUR-

ING GENERATOR TEST AND THE UTILITY POWER IS PRESENT AS WELLAS DURING A UTILITY

POWER FAILURE. SEE SEQUENCE OF OPERATION THIS SHEET.

SEQUENCE OF OPERATION

A. THE UTILITY POWER FAILS OR AGENERATOR TEST START SIGNAL OCCURS,

CAUSING THE LOUVER TO OPEN QUICKLY AND WHEN FULLY OPEN CAUSES THE

GENERATOR TO START.

NOTE THAT THE LOUVER OPEN SIGNAL MUST PASS THROUGH THE GENERATOR

CONTROLS SUCH THAT A SIGNAL TELLING THE GENERATOR TO START OPENS

THE LOUVER. THEN WITH THE LOUVER OPEN, THE END SWITCH ALLOWS THE

GENERATOR TO START.

GENERAL UTILITY VOLTAGE OR THE LACK THEREOF, CANNOT BE USED TO

OPEN THE LOUVER BECAUSE A SINGLE PHASE POWER FAILURE COULD CAUSE

THE TRANSFER SWITCH TO TELL THE GENERATOR TO START BUT WITH THE

LOUVER POWERED FROM THE ENERGIZED PHASE, THE LOUVER DOES NOT

OPEN AND BLOCKS THE GENERATOR FROM STARTING.

B. THE GENERATOR STARTS AND RUNS WITH THE LOUVER WIDE OPEN.

C. THE UTILITY POWER IS RESTORED, THE TRANSFER SWITCH SWITCHES TO

UTILITY POWER AND THE GENERATOR GOES INTO ITS COOL DOWN MODE. THE

LOUVER REMAINS OPEN. WHEN THE GENERATOR FINISHES THE COOL DOWN

CYCLE AND SHUTS DOWN, THE LOUVER MOTOR IS ACTIVATED CLOSING THE

LOUVER.

SECTION 5 OF THE SPECIFICATIONS ON SHEET E4.1 INDICATES THAT THE

PURPOSE OF THIS CATALOG SHEET IS TO PROVIDE INFORMATION TO THE

CONTRACTOR REGARDING THE GENERAL REQUIREMENTS OF THE MATERI-

AL ITEM.

THE USE OF THIS CATALOG SHEET SHALL BE IN COMPLIANCE WITH OPEN

AND FAIR COMPETITION.

IN NO CASE SHALL THE INCLUSION OF THIS CATALOG SHEET BE CON-

STRUED TO PREVENT ANY MANUFACTURER FROM PROPOSING AN EQUIVA-

LENT MATERIAL ITEM TO ONE LISTED HERE.
