SECTION I INTRODUCTION The Phase 3 computerized system is a fully programmable, highly sophisticated dryer control system. ADC has designed the Phase 3 to be the most versatile and reliable coin-op control system available. To eliminate as many moving parts as possible, ALL Phase 3 programming is done through the membrane switch on the front of the control panel. The switch (PS) that puts the computer into the program mode is a single, sealed, military specification toggle switch.
Bad Coin Lockout Each coin entry is monitored. Should someone tamper with the coin acceptor or attempt to insert a foreign object, the microprocessor controller (computer) will “LOCK UP” and will not accept any entries until the reset time has elapsed (approximately 15-seconds). Once the reset time has expired, the microprocessor controller (computer) will automatically reset itself for the next coin entry. Temperature Conversion When the temperature conversion status is changed (i.e.
Antiwrinkle This program selection helps keep permanent press items wrinkle free, when they are not removed from the dryer promptly at the end of the drying and cooling cycle. The owner programs the dryer to automatically restart in the cool down cycle, if the clothes are not removed in a preprogrammed amount of time. The Antiwrinkle Program settings are: 1. Guard Delay Time ---------- 1 to 9 minutes 2. Guard On Time ------------- 1 to 99-seconds 3.
SECTION II INSTALLATION PROCEDURES A. INSTALLATION The dryer is mounted on a skid by four (4) bolts. The front two (2) bolts are located on the floor of the lint compartment. The other two (2) are located on the base at the rear of the dryer. NOTE: Always keep the dryer in an upright position. B. LOCATION OF THE DRYER Approximately 2 feet (0.609 meters) should be allowed at the rear of the dryer for the duct and for ease of maintenance. The dryer should be level. The four (4) legs are adjustable.
CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors. Every 6 months, inspect the exhaust ducting and remove any lint build up. C. DRYER ENCLOSURE Bulkheads and partitions should be made of noncombustible materials. D. AIR INTAKE Make-up air will effect drying time, efficiency, and fire safety margins.
F. COMMON MAIN DUCT When individual exhaust is impossible, a common main duct may be used. However, strict attention must be given to the construction of the duct to insure proper exhaust and to prevent restrictions in the airflow. (Refer to the illustrations below.) G. ELECTRIC DRYERS Insure that the power supply is sufficient to operate the dryer. Low voltage and amperage will cause poor drying, overheated motors, poor relay function, and reduced fire safety margins.
H. GAS DRYERS ALL dryers are provided with 1/2” gas lines. Consult your local gas supplier for correct line size and pressure. The built in regulator provides 3.5 inches (8.7 mb) water column (W.C.) at the manifold for natural gas. Liquid propane (L.P.) gas must be regulated in line by the supplier to 10.5 inches (26.1 mb) water column. A shutoff valve should be installed at the rear of the dryer for easy servicing and safety. Gas connections should only be made by qualified personnel. I.
An impulse trap and filter should be installed at each dryer. After 1 or 2 days of operation, the following maintenance should be performed: 1. Pressure should be 10-15 psig (0.69-1.03 bars). 2. Filter and traps should be clean and operational. 3. There should be proper flow of steam and condensate. 4. There should be sufficient make-up air to the heat exchanger. 5. The dryer should be properly exhausted. K.
SECTION III L.E.D.
SECTION IV OPERATING INSTRUCTIONS NOTE: Unless otherwise specified at the time of ordering, the Phase 3 microprocessor controller (computer) has been programmed by the factory with the parameters shown on page 47 and page 48. Should program changes be found necessary, please read this manual carefully to thoroughly familiarize yourself with the Phase 3 programming characteristics. A. TIMED MODE 1. When turning on power or when no cycle is in progress, the light emitting diode (L.E.D.
3. Select temperature by pushing “HI TEMP,” “LO TEMP,” or “PERM PRESS.” The dryer will start, the light emitting diode (L.E.D.) display will read the temperature cycle selected, and the drying time portion of the L.E.D. display will read “00” and count upward as time elapses. NOTE: If the door is opened during a cycle, both the heat and motor will stop. However, the Phase 3 microprocessor controller (computer) will continue to count upwards in time.
SECTION V PROGRAM SELECTIONS NOTE: Programs are stored in the computer memory and are cataloged as program locations (PL). Temperature Display Mode By closing the Program Switch (PS), the display will read the temperature in the dryer in either Fahrenheit or Celsius, depending on how the PL01 temperature conversion status is set. The temperature display mode can be activated while the dryer is in the operating cycle or off.
At the end of the drying cycle, the dryer will go into the cool down cycle for the time period programmed (PL04, PL06, or PL08) or until the temperature has dropped to the programmed cool down temperature (PL04, PL06, or PL08). NOTE: Due to humidity, atmospheric pressure, percentage of extraction, etc., the desired dryness level may vary. It is suggested that the owner determine which level of dryness (90% to 100%) is best suited for his/her application by experimenting with a few test loads.
Bad Coin Lockout Status (bCLO) In this program status, the computer counts in milliseconds the amount of time required for a coin entry signal. If someone should tamper with the coin acceptor or attempt to insert a foreign object, the Phase 3 microprocessor controller (computer) will lock up, shut the dryer down, and the display will read “OFF.” This condition will be evident, even if coins are inserted, until the program is manually reset by closing and reopening the program switch (PS).
Dual Coin In the time accumulation mode, when using a dual coin acceptor, once the “Amount To Start” (“AtSt”) has been inserted, the addition of a coin(s) yields more time. The amount of time accumulated for each additional coin inserted is determined by the “Time Per Left Coin” (“tPLC”) program (PL11). The “Time Per Left Coin” (“tPLC”) is determined by taking the “Total Vend Time” divided by the “Amount To Start” (“AtSt”) (PL12) and then, multiplying by the “Left Coin Denomination” (“LCdE”).
Accumulative Coin (ACOn) When this program mode (“ACOn”) is selected, additional time can only be achieved when the “Amount For Additional Time” (“AFAt”) (PL13) has been inserted. Single Coin Acceptor Example No. 1: Using a 25¢ coin acceptor with the desired “Amount To Start” (“AtSt”) being 50¢ for 24 minutes, the Phase 3 microprocessor controller (computer) would yield more time (24 minutes) only when an additional 50¢ is inserted.
PL02 - Dryness Level (drYL) When in the automatic mode or free dry mode, the dryer will run until the preset level of dryness (Number of Auto Peaks) has been reached. The dryness level is programmable from a minimum of 1 to a maximum of 99. NOTE: Due to humidity, atmospheric pressure, water retention in the garment etc., the desired dryness level may vary. It is suggested that the owner determine which level of dryness is best suited for his application by experimenting with a few test loads.
PL09 - Left Coin Slot Denomination (LCdE) In the case of a single coin acceptor, this program setting is determined by the value of the coin acceptor (i.e., 25¢). When a dual coin acceptor is used, this program setting is determined by the left coin slot acceptor value (lower coin value). Program settings are from a minimum of 1 to a maximum of 9999. PL10 - Right Coin Slot Denomination (rCdE) This program needs only to be set when a dual coin acceptor is used.
PL15 - Antiwrinkle Timing 1. Guard Delay Time (GdLY) This program controls the dwell (stop) time and activation of the antiwrinkle “Guard On Time” (“Gont”). The dwell (stop) time can be programmed from a minimum of 1 minute to a maximum of 9 minutes in 1 minute increments. 2. Guard On Time (Gont) This setting controls the amount of time that the basket (tumbler) will turn, without heat, when the antiwrinkle is active (“Grd”).
SECTION VI INTRODUCTION TO PROGRAMMING ALL programming is done through the keyboard (touch pad) selection buttons on the front of the control panel. To change programs or to put the computer in the temperature or coin count display modes, the program switch (PS) located on the back side of the computer must be put into the closed position (PSC).
Display Reads To speed up, “Push” and “Hold In” LO Temp selection button. Display reads program locations and will advance downward until LO Temp selection button is released. PL04 LO TEMP PL03 PL02 PL01 To enter a specific program location (i.e. PL01) “Push” the Perm Press selection button. Display Will Read specific program location called up.
