Faults _________________________________
Gen 2 Card Reader Communication Fault
An exhaust probe fault occurs when the control detects that
the exhaust temperature transducer is reading a temperature
that is out of the probe’s normal operating temperature range
for more than 3-seconds. There is an automatic fault
clearing feature for this fault. If the fault condition no longer
exists, the control will clear the fault condition and return to
READY Mode.
This fault occurs when the control has not received a health
check function from the Gen 2 debit card reader in
30-seconds. If this fault occurs in Ready or Vending Modes,
the control will log the fault and display “OUT OF ORDER”.
Once the control enters READY Mode and the fault has not
been corrected or cleared, the control will display “OUT OF
ORDER”. The fault is self clearing; therefore, once
communication is reestablished, the control will clear the
OUT OF ORDER condition and allow full dryer functionality
again.
Exhaust Probe
Axial Probe
An axial thermistor probe fault occurs when the control
detects that the axial thermistor is reading a temperature
that is out of the probe’s normal operating temperature range
for more than 30-seconds, usually an open or shorted probe
condition. There is an automatic fault clearing feature for
this fault. If the fault condition no longer exists, the control
will clear the fault condition and return to READY Mode.
Events _________________________________
Radiant Sensor Fault Count
A radiant sensor fault count will occur when a gas model
dryer attempts to turn on the burner system and never
receives a 120V return signal within a predefined time.
Burner Igniter Fault Count
Sail Switch Closed
A sail switch closed fault occurs when a cycle is starting up
from either READY Mode, PAUSE Mode or any other idle
state. Once a temperature/cycle is selected the control will
start the time and verify the sail switch is open, if it is not,
the control will display on the screen that the control is
“STARTING” and will not turn on the FAN, DRIVE or HEAT.
The control will allow the sail switch 10-seconds to open
before the control faults out with a SAIL SWITCH CLOSED
FAULT. Once a SAIL SWITCH CLOSED FAULT is detected
the control will log the fault and will not allow the cycle to
continue. The control will display “SAIL SWITCH CLOSED
FAULT, SELECT CYCLE TO RESTART, when the fault is
detected.
A burner ignition fault count will occur when a gas model
dryer attempts to turn on the burner system and receives a
120V on the burner return signal but it does not transition
to a 0V return signal within a predefined time.
Exhaust High Limit
This location is a count of the times that the exhaust high
limit has been sensed in the open position.
Reverse Rotation Sensor Fault
REVERSE ROTATION SENSOR FAULT is identical to
FORWARD ROTATION FAULT, however it pertains to the
reversing drive output instead of the forward drive output.
Sail Switch Open
Forward Rotation Sensor Fault
A sail switch open fault occurs when a cycle is starting from
either READY Mode, PAUSE Mode or any other idle state.
If the sail switch does not close within the allotted
10-seconds the control will log the fault and will not allow
the cycle to continue. The control will display “SAIL SWITCH
OPEN FAULT, CHECK MAIN DOOR AND LINT ACCESS
AND SELECT CYCLE TO RESTART”. A sail switch open
fault can also occur once a cycle is in process. If the control
detects that the sail switch has opened, the heat will
immediately turn off and if the sail switch fails to close within
the allotted 30-seconds, the control will fault and display
“SAIL SWITCH OPEN FAULT, CHECK MAIN DOOR AND
LINT ACCESS AND SELECT CYCLE TO RESTART”.
A forward rotation fault pertains only to reversing machines.
The way this fault works is if the dryer is reversing and is
running a cycle that has the reversing option enabled, if a
rotation sensor fault condition is detected, the drive output
would be shut off. Then the dryer will transition to a
reversing drive output. If the dryer continues to run without
an issue, the machine will continue to run with the forward
drive output disabled until the next cycle is started. If the
Reversing Mode also fails the control will enter a ROTATION
SENSOR FAULT disabling the machine. The next cycle
should operate with both drive outputs, that way, if the issue
still exists the control will fault out again disabling the fault
drive output.
Rotation Sensor Fault
S.A.F.E. Disabled – Water Not Connected
A rotation sensor fault occurs when the control is in a cycle
and does not detect any rotation sensor pulses in more
than 10-seconds.
This event pertains only to dryers with a fire detection
system. If the control senses a lack of water pressure, this
event will appear.
Exhaust High Temp Fault
Bad Coin Count
An exhaust high temperature fault occurs when the exhaust
probe is detecting a tumbler temperature that is 20° F above
the maximum dryer temperature set point for more than
10-seconds.
This location is a count of all the bad coin occurrences that
were detected from the coin input.
Blocked Coin Drop
This fault occurs if the control senses a blockage in the coin
input. If the coin input is blocked for more than
8-seconds the control will go to out of order and will not
allow the control to start a cycle. This fault has both
automatic and manual fault clearing. If the condition is
corrected the control will recover from out of order
immediately after the blockage is no longer seen.
