ROTATION SENSOR FAULT – This routine monitors the pulses from the rotational sensor input. It basically
times the dwell between signals. If the time between the pulses exceeds 10-seconds, the Phase 7 non-coin
microprocessor controller (computer) will trigger a “Rotation Sensor Fault” condition and will go into Fault Mode
with a brief audio indication. Depending on the model type, the dryer will run the fan with no heat for 3 minutes
or until the temperature drops below 100° F (38° C) for GAS REVERSING, ELECTRIC REVERSING and
STEAM REVERSING models. Once the basket (tumbler) temperature is below 100° F (38° C), or the 3
minutes expire, the Phase 7 non-coin microprocessor controller (computer) will shut off
ALL outputs and remain
in Fault Mode until the dryer is addressed. If the dryer model is a GAS NON-REVERSING, ELECTRIC
NON-REVERSING or STEAM NON-REVERSING model, the Phase 7 non-coin microprocessor controller
(computer) will immediately shut off
ALL outputs, regardless of the basket (tumbler) temperature, and remain in
Fault Mode until the dryer is addressed.
SAIL SWITCH CLOSED FAULT – This routine prevents the start-up of the dryer unless the sail switch is in
the open position. If the sail switch is in the closed position prior to starting, the Phase 7 non-coin microprocessor
controller (computer) will display “PLEASE WAIT START UP IN PROCESS” and will allow the Phase 7
non-coin microprocessor controller (computer) 10-seconds for the sail switch to open before faulting out on a
“Sail Switch Closed Fault”. Once the dryer faults out on the “Sail Switch Closed Fault”, the dryer will not be
allowed to start. This routine is also monitored at every start-up, including a start-up after being in Pause Mode.
If the sail switch is in the closed position prior to starting from a Pause Mode, the Phase 7 non-coin microprocessor
controller (computer) will display “PLEASE WAIT RESTART IN PROCESS” and allow the Phase 7 non-coin
microprocessor controller (computer) 10-seconds for the sail switch to open before faulting out on a “Sail
Switch Closed Fault”. Again, once the dryer faults out on the “Sail Switch Closed Fault”, the dryer will not be
allowed to start. Anytime the fault occurs, there will be an audio indication and start/restart will be prevented.
SAIL SWITCH OPEN FAULT – If the sail switch does not close within 8-seconds of starting or restarting a
cycle, the Phase 7 non-coin microprocessor controller (computer) will display “Sail Switch Open Fault” condition.
Or, if the sail switch opens during a cycle, the Phase 7 non-coin microprocessor controller (computer) will
immediately shut off the heat output and monitor how long the sail switch is open for. If the sail switch is open
for more than 30-seconds, the Phase 7 non-coin microprocessor controller (computer) will display “Sail Switch
Open Fault” condition and go into Fault Mode with a brief audio indication. If the basket (tumbler) temperature
is above 100° F (38° C), the Phase 7 non-coin microprocessor controller (computer) will continue to display
“Open Sail Switch 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 non-coin microprocessor controller (computer) will shut off ALL outputs and remain in Fault
Mode until the dryer is addressed.
F.S.S. ACTIVATED – Indicates that the Phase 7 non-coin microprocessor controller (computer) has detected
a fire and is currently extinguishing the flame.
F.S.S. WAS ACTIVATED – Indicates that the Phase 7 non-coin microprocessor controller (computer) detected
a fire and has extinguished the flame.
