FIRE SUPPRESSION SYSTEM DIAGNOSTICS MESSAGES

OPEN THERMISTOR PROBE – This message indicates that the fire suppression system thermistor probe either is not connected or is damaged. If this condition is detected, the microprocessor controller (computer) will immediately enter S.A.F.E. SYSTEM DISABLED Mode.

SHORTED THERMISTOR PROBE – This message indicates that the fire suppression system thermistor probe is damaged or the wiring is shorted. If this condition is detected, the microprocessor controller (computer) 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 microprocessor controller (computer). If this condition is detected, the microprocessor controller (computer) 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 microprocessor controller (computer) 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 microprocessor controller (computer) 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 microprocessor controller (computer) 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 microprocessor controller (computer) 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 microprocessor controller (computer) will continue to monitor the condition for 1 minute before exiting S.A.F.E. SYSTEM DISABLED Mode.

STARTING A CYCLE WHEN MICROPROCESSOR CONTROLLER (COMPUTER) IS IN “S.A.F.E. SYSTEM IS DISABLED” MODE

When the fire suppression system is disabled, the user can still start a cycle. However, when a cycle is started, the non-coin microprocessor controller (computer) 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.
