The “A” Factor is adjustable from 1 to 99. These parameters are the factors that the Phase 5 microprocessor controller (computer) utilizes when programmed for an “Automatic Drying Cycle.” The “A” Factor slope program, pertains to the thermal characteristic of each model dryer. The “b” Factor, heat loss (offset) program, also pertains to the thermal characteristics of each model dryer. This factor setting is dependent upon the model dryer and type of heating unit. The “A” and “b” Factors have not been preprogrammed by the factory and must be programmed if the Phase 5 microprocessor controller (computer) programming is changed to be used in the Automatic Mode. The “A” and “b” Factors must be programmed for the particular dryer model and heating unit as shown in the “A” and “b” Factor (parameter) table on page 60 of this manual. 24 SECTION V PROGRAMMING INSTRUCTIONS A. INTRODUCTION TO PROGRAMMING The various program (parameters) dryer selections are stored in the computer memory and are cataloged as “Program Locations” (PL) 1 through 17. These programs (parameters) have been preprogrammed by the factory as noted on page 52 and page 53 (for ALL models except AD-26/AD-295 and AD-540/WDA-540) and page 54 and page 55 (for dryer models AD-26/AD-295 and AD-540/WDA-540 ONLY) of this manual. The various program selections available are outlined in the proceeding section (Section IV). ALL programming is done through the keyboard (touch pad) selection buttons on the front of the control panel. To change programs (parameters) or to put the Phase 5 microprocessor controller (computer) in the temperature display mode or the coin count display mode, the Program Switch (PS) located on the back side of the microprocessor controller (computer) must be put into the (down) position (PSC). First make sure there is no cycle in progress and the light emitting diode (L.E.D.) display reads “FILL” and/or “Amount To Start,” or “FILL” and/or “FrEE.” Close the Program Switch (PSC). The L.E.D. display will now read the temperature in the dryer (i.e., 72° F [22° C]). From this point, any of the 17 program locations can be accessed by pressing the “PERM PRESS” key once, at which time the L.E.D. display will read “PL01.” To alter programming, the operator must first locate the program location or parameter to be changed. To advance to the specific program location press the “HI TEMP” key until the desired program location is displayed (i.e. PL01, PL02, etc.). The “LO TEMP” key will advance the program locations downward (i.e., PL11, PL10, etc.). Once the correct program location is displayed and access to change is desired, press the “PERM PRESS” key. The “PERM PRESS” key provides two (2) functions: 1. Allows access into a Program Location (PL). 2. Advances to next bit (part of a program location) or next location. NOTE: When in a Program Location (PL) and the “PERM PRESS” key is pressed, whatever parameter is displayed will be stored in the microprocessor controller’s (computer’s) memory and the programming is now advanced to the next step (bit) or program location. The “HI TEMP” or “LO TEMP” keys provide the following functions: 1. Change numeric values...“HI TEMP” increases and “LO TEMP” decreases. 2. Flip-flop for status changes...by pressing either key, a status will revert back and forth no matter which of the two (2) keys is pressed. 25 If the change to be made is a numerical one (i.e., time or temperature), the operator must now press the “HI TEMP” key to increase the number value, or press the “LO TEMP” key to lower/increase the number value. Pressing the “PERM PRESS” key will store the change and advance to the next step (bit) or program location. NOTE: To accelerate increase/upward value, press and hold in “HI TEMP” key. To accelerate decrease/downward value, press and hold in “LO TEMP” key. NOTE: When making numerical changes, please keep in mind to stay within the programming limits shown. If the change to be made is a status change (i.e., to change from °FAr to °CEL) simply press the “HI TEMP” or “LO TEMP” key and the light emitting diode (L.E.D.) display will revert back and forth between status choices (i.e. “Grd” and “nGrd”). Once the correct status is displayed, pressing the “PERM PRESS” key will store the change and advance to the next step (bit) or program location. Once the change or changes desired are made, to exit program mode flip up (open) the Program Switch (PS). NOTE: You can exit the programming mode at any time (even if you are in the middle of a program location) by simply opening the Program Switch (PS). However, if a change was made be sure the “PERM PRESS” key is pressed before opening the Program Switch (PS) to insure the change was stored in the microprocessor controller’s (computer’s) memory. B.
