NOTE: The control will not let the user continue until the valve test has been completed.

S.A.F.E. SYSTEM DIAGNOSTICS

In the event that the Phase 7 non-coin microprocessor controller (computer) detects a fault in the S.A.F.E. system, the control will display the message “S.A.F.E. SYSTEM DISABLED…READY.” To find out why the S.A.F.E. system is disabling, press and hold the red “STOP/CLEAR” and green “START” keys. This will cause the control to display a diagnostic message, as detailed in the “S.A.F.E. SYSTEM Diagnostics Messages” section.

S.A.F.E. SYSTEM DIAGNOSTICS MESSAGES

OPEN THERMISTOR PROBE – This message indicates that the S.A.F.E. system thermistor probe either is not connected or is damaged. If this condition is detected, the Phase 7 non-coin control will immediately enter S.A.F.E. SYSTEM DISABLED mode.

SHORTED THERMISTOR PROBE – This message indicates that the S.A.F.E. system thermistor probe is damaged or the wiring is shorted. If this condition is detected, the Phase 7 non-coin control will immediately enter S.A.F.E. SYSTEM DISABLED mode.

DISCONNECTED WATER VALVE – This message indicates that the water valve is open or that it is not connected to the control. If this condition is detected, the Phase 7 non-coin control will continue to monitor the condition for a period of 5 minutes before entering S.A.F.E. SYSTEM DISABLED mode. Once the condition is corrected, the control will continue to monitor the condition for 1 minute before exiting S.A.F.E. SYSTEM DISABLED mode.

SHORTED WATER VALVE – This message indicates that the water valve is shorted or that the wiring to the valve is shorted. If this condition is detected, the Phase 7 non-coin control will continue to monitor the condition for a period of 5 minutes before entering S.A.F.E. SYSTEM DISABLED mode. Once the condition is corrected, the control will continue to monitor the condition for 1 minute before exiting S.A.F.E. SYSTEM DISABLED mode.

WATER NOT CONNECTED – This indicates that there is no water pressure at the water valve. This will occur if water is not connected to the dryer, or if there is low water pressure in the water line coming to the dryer. This could also signify a defective pressure switch or defective wiring to the pressure switch. If this condition is detected, the Phase 7 non-coin control will continue to monitor the condition for a period of 5 minutes before entering S.A.F.E. SYSTEM DISABLED mode. Once the condition is corrected, the control will continue to monitor the condition for 1 minute before exiting S.A.F.E. SYSTEM DISABLED mode.

STARTING A CYCLE

WHEN COMPUTER IS IN “S.A.F.E. SYSTEM IS DISABLED” MODE

When the S.A.F.E. system is disabled, the user can still start a cycle. However, when a cycle is started, the control will display the following message: “S.A.F.E. SYSTEM IS DISABLED. PRESS ‘START’ TO CONTINUE.” This message will be displayed every time a cycle is started, until the disabling condition has been corrected.
