SECTION VIII

PHASE 7 DUAL MICROPROCESSOR CONTROLLER (DMC)

COMPUTER SYSTEM DIAGNOSTICS

IMPORTANT: YOU MUST DISCONNECTAND LOCK OUT THE ELECTRIC SUPPLY AND THE GAS OR STEAM SUPPLY BEFORE ANY COVERS OR GUARDS ARE REMOVED FROM THE MACHINE, TO ALLOWACCESS FOR CLEANING,ADJUSTING, INSTALLATION, OR TESTING OFANY EQUIPMENT PER OSHA (Occupational Safety and HealthAdministration)

STANDARDS.

ALL major circuits, including the door, the microprocessor temperature sensor, and the heat and motor circuits are monitored. The Phase 7 dual microprocessor controller (DMC) computer will inform the user via the liquid crystal display (L.C.D.) of certain failure messages, along with light emitting diode (L.E.D.) indicators on the Inputs/Outputs (I/O) on the Phase 7 DMC (computer) board.

ERROR MESSAGES:

NOTE: Any error associated with the “Out of Order” message can be identified by pressing the “LO” key while in the “Out of Order” condition. If the “HI” key is pressed during this time, the remaining credit can be viewed. Any “Out of Order” message is immediately followed by a 3-second tone. If the fault has been corrected, holding the “PAUSE” key for 3-seconds will clear the fault message. If more than one (1) fault occurred at the same time after the first fault is cleared, the next fault will be displayed and will need to be cleared. This will occur until ALL faults have been displayed. In Free Mode, the Phase 7 DMC (computer) will not display “Out of Order”; it will just display the fault.

A. DIAGNOSTIC L.C.D. FAULT MESSAGES

MODEL FAULT – This routine monitors the inputs, such as the sail switch and gas valve, to determine the type of dryer the Phase 7 DMC (computer) is. Steam dryers DO NOT use a sail switch or valve input, and an electric dryer will not use a gas valve input. These signals allow the Phase 7 DMC (computer) to interpret what type of dryer it is controlling. The Phase 7 DMC (computer) determines what the expected dryer responses should be for that specific heat-type dryer. Anytime a model fault is detected, the Phase 7 DMC (computer) will interrupt the cycle and will display “MODEL FAULT” and will go into a Fault Mode with a brief audio indication. If the basket (tumbler) temperature is above 100°F (38°C) at the time of the failure, the Phase 7 DMC (computer) will continue to display “MODEL FAULT” while the dryer cools by running with no heat for 3 minutes or until the temperature drops below 100°F (38°C). Once the basket (tumbler) temperature is below 100°F (38°C), or the 3 minutes expire, the Phase 7 DMC (computer) will shut off ALL outputs and will remain in Fault Mode until the dryer is addressed.

NOTE: If a model error occurs, the microprocessor will always default to the “gas” type for safety reasons. Also, the dryer is stopped and forced into a restart condition to reevaluate ALL expected responses.
