THE INTENT OF THIS SECTION IS TO PROVIDE SUFFICIENT INFORMATION TO ALLOW DETERMINATION OF THE APPROPRIATE RATING TIER LEVEL AND SELECTION OF AN ACCEPTABLE MODEL. THIS PROCESS INVOLVES A DETAILED ANALYSIS OF THE APPLICATION DUTY CYCLE IN TERMS OF TIME SPENT AT VARIOUS IDENTIFIABLE LOAD CONDITIONS AND TIME SPENT UNDER VARIOUS IDENTIFIABLE CONDITIONS. A STEP-BY-STEP EXAMPLE DEPICTS HOW THE PROCESS UTILIZES THIS INFORMATION IN TERMS OF LOAD FACTOR AND FACTOR TO CALCULATE A RATING FACTOR. THE RATING FACTOR CHART ALLOWS THE APPROPRIATE TIER LEVEL TO BE IDENTIFIED AS ONE MAJOR SELECTION CRITERIA. THE INDUSTRIAL SELECTION GUIDE WORKSHEET LEADS THE ANALYST STEP-BY-STEP THROUGH THE DISCOVERY PROCESS USING THE DUTY CYCLE AND OTHER REQUESTED INFORMATION TO SELECT A FINAL TIER LEVEL AND CHOICE FOR THE APPLICATION IN QUESTION. ANY FURTHER INQUIRIES CONCERNING THE UTILIZATION OF THIS PROCESS OR TO PURSUE SITUATIONS THAT DO NOT FIT THIS SELECTION PROCESS SHOULD BE DIRECTED TO THE FACTORY VIA YOUR NORMAL CONTACTS AND PROCEDURES. LOAD FACTOR LOAD FACTOR (THE AVERAGE DEMAND ON AN ) CAN BE DETERMINED THROUGH ACTUAL FUEL CONSUMPTION. IT CAN BE DETERMINED BY DIVIDING THE ACTUAL FUEL USED IN A WORK CYCLE BY THE AMOUNT OF FUEL THAT COULD BE CONSUMED AT THE STATED RATING DURING THE SAME TIME
PERIOD. ACTUAL FUEL CONSUMED (GAL OR L) RATED FUEL RATE X LENGTH OF WORK CYCLE (GPH OR L/H) (H) A MORE PRECISE DETERMINATION OF LOAD FACTOR IS THROUGH DETAILED ANALYSIS OF THE DUTY CYCLE. DUTY CYCLE A DUTY CYCLE ANALYSIS IS CRITICAL IN THE DETERMINATION OF THE APPROPRIATE RATING TIER. THE DUTY CYCLE IS DEFINED AS THE TIME SPENT AT VARIOUS S AND S. IT IS BEST TO DIVIDE THE DUTY CYCLE INTO AS MANY ELEMENTS OF AS POSSIBLE (RATED, %'S OF RATED AND IDLE) AND AS MANY ELEMENTS OF AS POSSIBLE (RATED, %'S OF RATED, HIGH IDLE, AND LOW IDLE). THESE VALUES ARE USED IN THE CALCULATIONS OF LOAD FACTOR AND FACTOR. MULTIPLYING THE LOAD FACTOR AND THE FACTOR TOGETHER RESULTS IN A RATING FACTOR. THIS RATING FACTOR HELPS DETERMINE THE PROPER RATING TIER FOR THIS DUTY CYCLE.
