PHASE 7 NON-COIN SYSTEM DIAGNOSTICS

IMPORTANT: YOU MUST DISCONNECT AND LOCKOUT THE ELECTRIC SUPPLY AND THE GAS SUPPLY OR THE STEAM SUPPLY BEFORE ANY COVERS OR GUARDS ARE REMOVED FROM THE MACHINE TO ALLOW ACCESS FOR CLEANING, ADJUSTING, INSTALLATION, OR TESTING OF ANY EQUIPMENT PER OCCUPATIONAL SAFETY AND HEALTH ADMINISTRATION (OSHA) STANDARDS.

ALL major circuits, including door, microprocessor temperature sensor, heat and motor circuits are monitored. The Phase 7 non-coin microprocessor controller (computer) will inform the user, via the light emitting diode (L.E.D.) display of certain failure messages, along with L.E.D. indicators on the Input/ Output board on the back panel of the front right control door.

A. DIAGNOSTIC (L.E.D. DISPLAY) FAULT MESSAGES

MAIN DOOR OPENED – A main door is open, when it should be closed.

EXHAUST HIGH TEMP FAULT – Indicates the temperature in the tumbler is above 220º F (104º C).

LINT ACCESS OPEN – Indicates the lint drawer is open and needs to be closed.

EXHAUST HIGH LIMIT FAULT – Indicates the temperature disk in the exhaust has opened.

SAIL SWITCH CLOSED FAULT – Sail switch is closed and should be opened.

SAIL SWITCH OPEN FAULT – Sail switch is open and should be closed.

BURNER HIGH LIMIT FAULT – Indicates the temperature disk in the burner has opened.

BURNER IGNITION CONTROL FAULT – No signal to gas valve from Direct Spark Ignition (DSI) module during trial for ignition time.

IGNITION FAULT – Gas valve did not remain open after trial for ignition. Indicates that no flame was detected.

FLAME FAULT – Indicates flame was detected during trial for ignition, but failed sometime after. This condition must reoccur for five (5) retries before fault occurs.

ROTATION FAULT – Indicates the tumbler is not rotating.

OPEN EXHAUST TEMPERATURE PROBE – Indicates the exhaust temperature probe is open or shorted.

OPEN SENSOR ACTIVATED FIRE EXTINGUISHING (S.A.F.E.) SYSTEM PROBE FAULT – Indicates the temperature probe for the S.A.F.E. system is open or shorted.

LOW VOLTAGE FAULT – Indicates power has dropped below the operating values and will shutdown.
