door is not opened. The cylinder will tumble for 30 seconds every
two minutes for up to one hour.
If the door hasn’t been opened and no keys have been pressed
one hour after the Anti-Wrinkle Tumble has ended, the control increments the Anti-Wrinkle Time Exceeded audit counter and enters Delayed Tumble. The cylinder will tumble for two minutes
every 60 minutes for up to 18 hours.
Reversing Mode (reversing models only)
Models equipped with the reversing feature will rotate in the forward direction, pause, rotate in the reverse direction and then
pause for programmable times and segments of the cycle. Factory
default reversing rotate time is 30 seconds and reversing stop
time is 6 seconds for all cycles with reversing enabled.

There are 30 machine cycles that can be selected and run. Machine cycles can be modified or made “unavailable” by manually
editing them in Modify Cycle Menu or by using the PDA to
download a modified machine cycle into the control. Machine cycles cannot be deleted, but can be made “unavailable” so that
they are not visible from the Cycle Menu. New machine cycles
cannot be created, but existing machine cycles that have been
edited to be “unavailable” may be re-edited to be available again.
Machine Cycle Operation
When a cycle is run, the control runs the cycle segment by segment in a sequence. First the control examines the Cycle Type
chosen to determine if it is a Time Dry, Auto-Dry or Moisture
Dry (if equipped) cycle type. Then the first segment is examined
to see if it is programmed to on or oFF. If the segment is programmed to oFF, control skips to the next segment.
At the start of some machine cycles, the control displays a Total
Remaining Cycle time. This time is taken from the machine cycles as they are programmed. The Total Remaining Cycle Time
begins to count down as soon as the cycle is started.
Time Dry Cycle
2. Press Start to start selected cycle.
NOTE: If door is not closed when the Start keypad is
pressed, display will show door.
In this type of cycle, the control will regulate the temperature and
time duration as programmed for the cycle chosen.
Auto-Dry Cycle
If this type of cycle is selected, the control determines the cycle
time based on the temperature and dryness level programmed for
the cycle chosen.
Moisture Dry Cycle (if equipped)
In this type of cycle, the control checks the programmed material
type, programmed target moisture content, programmed temperature and the data received from the moisture sensing system to
achieve the desire results.
Rotation Sensor Equipped Machines
On machines equipped with a rotation sensor, the control monitors the rotation sensor to verify the cylinder is rotating. The control calculates the cylinder’s RPM. If the RPM drops to zero
while the cylinder is supposed to be rotating, the control will advance to the Cool Down segment of the cycle and an error message will be displayed.

press the Back keypad to return and run the test again. If the control ran the whole test reading the expected moisture sensor level
and without an intermittent signal or high resistance, PASS will
be shown. If either the loading or lint doors are opened during the
test, the control will reset the test step and allow it to be run
again. When the test is complete and result is displayed, the control sounds a 5 second audio signal. Press a key to advance to the
next test step. If the Up or Down keypad is pressed while the test
is in progress the control will toggle between displays HH, rnCHH and SnrHHH. If the display is left on rnC HH or SnrHHH for
5 seconds the control will revert to showing rnC 1.
Moisture Sensor Test (Resistance Test Jumper)
This step is skipped if the control is not configured for Moisture
Sensing. When entering this test, the control will show rnC 2
while flashing the Start key LED one second on/one second off,
allowing the user to place the 510k Ohm resistor between the cylinder and the baffle (black jumper) which simulates an expected
moisture sensor level. When the Start keypad is pressed, this step
energizes the Fan Motor Contactor and Forward Motor Contactor
and the control will show HH. The moisture sensor test is 30 seconds. During this 30 second period, the control is continually
monitoring the moisture sensor input for the expected moisture
sensor level. If an intermittent signal or unexpected resistance is
sensed before the time expires, the test is terminated and the control will show OPEn , indicating that the test has failed. At this
time, the user has the option to press the Back keypad to return
and run the test again. If the control ran the test reading the expected moisture sensor level and without an inttermittent signal
or unexpected resistance, PASS will be shown. If either the loading or lint doors are opened during the test, the control will reset
the test step and allow it to be run again. When the test is complete and result is displayed, the control sounds a 5 second audio
signal. Press a key to advance to the next test step. If the Up or
Down keypad is pressed while the test is in progress the control
will toggle between HH, rnC HH and SnrHHH. If the display is
left on rnC HH or SnrHHH for 5 seconds the control will revert
to showing rnC 2.
To exit Rotation Sensor Test, press the Back keypad. The control
will return to the testing mode.
Moisture Sensor Test (Shorted Test Jumper)
This step is skipped if the control is not configured for Moisture
Sensing. When entering this test, the control will show rnC 1
while flashing the Start LED one second on/one second off, allowing the user to short the cylinder to the baffle (orange jumper). When the Start key is pressed, this test step energizes the Fan
Motor Contactor and Forward Motor Contactor and the control
will show HH. The moisture sensor test is 30 seconds. During this
30 second period, the control is continually monitoring the moisture sensor input for the expected short circuit. If an intermittent
signal or high resistance is sensed before the 30 seconds expire,
the test is terminated and the control will show OPEn , indicating that the test has failed. At this time the user has the option to

10 Minute Test
Cycle
Determines if tumble dryer can function in a cycle for 10 minutes. Start pad will flash
one second on and one second off. The Start pad can be used to decrease time remaining. If Start pad is not pressed within 4.25 minutes, the control will return to Idle Mode.
Table 10
NOTE: If power to the control is turned off before 10 Minute Test Cycle has ended, the cycle will be cleared
from control.
These errors may occur during communications. When an error
occurs, the display indicates the error message on the control for
a few seconds. When a PDA communication error occurs, the audit counter Total Bad IR Communications is incremented, the
hour, date, and year of the event are saved, and the error code is
saved. An active machine cycle is not affected when there is an
error during PDA communications.
Open Thermistor Error
Any time the control senses a temperature less than 0°F [-18°C]
after the first three minutes of an active cycle, the control will go
to Cool Down, display this error message, and then turn on the
audio signal. The control will continue to display the error message until any of the keypads are pressed, the Cool Down portion
of the cycle has ended, and the temperature reading is greater
than 0°F [-18°C]. Press any keypad to stop audio signal. Once all
three occur, the control will return to the Idle Mode.
Shorted Thermistor Error
Any time the control senses a temperature greater than 210 + 4°F
[99°C + 16°C] during an active cycle, the control will enter the
Cool Down portion of the cycle, display this error message, and
turn on the audio signal. The control will continue to display the
error message until any of the keypads are pressed, the Cool
Down portion of the cycle has ended, and the temperature reading is less than 210°F [99°C]. Press any keypad to stop audio signal. Once all three occur, the control will return to the Idle Mode.
Stove and Cabinet Limit Errors
There are up to two Stove Limit thermostats and one Cabinet
Limit thermostat on the machine. While the heat relay is on, if the
stove temperature or cabinet temperature reaches the high temperature for the particular limit thermostat, the heater will turn off
automatically and the control will continue the cycle with no heat
until the limit thermostat resets. Once the control reaches the End
of Cycle the control will display the appropriate error message, if
programmed to do so, and sound the audio signal. The control
will continue displaying the error message until the control returns to Idle mode.
NOTE: On some models the stove and cabinet limit
thermostats need to be manually reset. The remainder
of the cycle will be run with no heat. On these models,
the thermostat(s) must be reset prior to cycling power
or the control will return back to Error Mode.
Auto Ignition Retry (Gas Models Only)
If the Ignition Control Module (ICM) fails to ignite the gas valve
the ICM will send an ICM Lockout Alarm to the control. When
the control receives the ICM Lockout Alarm it will increment the
ICM Lockout Alarm audit counter.
If the ICM needs to be manually reset, when the control receives
the ICM Lockout Alarm it will display the Cycle Stopped Menu
with text prompting the user to press the Start keypad to reset the
ICM. The user can continue to reset the ICM until there are no
more programmable retry attempts (factory default is 3) or the
gas ignites. On machines equipped with an ICM that does not
need to be manually reset, when the control receives the ICM
Lockout Alarm it will turn the heat relay off for twenty (20) seconds and then turn it back on to try and ignite the gas. The control will continue to try and ignite the gas until there are no more
programmable retry attempts (factory default is 3) or the gas ignites. If the ICM fails to ignite the gas on the last attempt the control will start the Cool Down portion of the cycle, display the heat
error message and sound the audio signal. When the Cool Down
portion of the cycle ends the control will continue to display the
error message until power is cycled to the machine or a user
presses the Back keypad.
Air Flow Switch Errors
The control will flag an Airflow Switch Error under several conditions. Airflow Switch Errors will be processed differently depending upon what state the machine was in when the error was
detected.
Airflow Switch Sensed Closed While Not In Run Mode
If an airflow switch is sensed closed 30 seconds after entering
Idle Mode, Pause Mode or End of Cycle Mode, the control will
display an error message until power is cycled or the error clears.
The cycle will not start and all user inputs will be ignored. If the
error does clear, the control will go back to its previous mode of
operation.
Airflow Switch Does Not Close After Cycle Started
If the airflow switch does not close within 5 seconds of the
start/re-start of a cycle, the control will go to the Cool Down portion of the cycle, display an error message and sound the audio
alarm. Once the Cool Down portion of the cycle ends, the control
will continue to display the error message until the power is cycled to the machine or the Back keypad is pressed.
If the airflow switch is open for at least one second, the heat will
be turned off and will remain off until the switch is observed

Machine Errors
closed for at least 5 seconds (it is flagged as an airflow switch
bounce). If there are 5 airflow switch bounces within 5 minutes
the control will go to the Cool Down portion of the cycle, display
an error message and sound the audio signal. When the Cool
Down portion of the cycle ends, the control will continue displaying the error message until power is cycled or a user presses the
Back keypad.
Rotation Sensor Error
If the machine is equipped with a rotation sensor, the control will
constantly monitor the input and calculate the cylinder’s rpm. If
the rpm drops to zero while the cylinder is supposed to be spinning, the control will go to the Cool Down portion of the cycle.
The control will display an error message and sound the audio
signal. Once the Cool Down portion ends, the control will continue to display the error message until power is cycled to the machine.
Fan Motor Contactor Error
If the control attempts to turn on the heater relay and the control
does not sense that the Fan Motor Contactor is closed, the control
will go to the Cool Down portion of the cycle, display an error
message and turn on the audio signal. Once the Cool Down portion of the cycle ends, the control will continue displaying the error message until power is cycled or the Back keypad is pressed.
period without user input, the control will declare a load sensed.
If at any time during this sensing period, user input is detected or
the control determines that there is no load present, it resets the
load detected counter. After this ten minute period with a consistent load sensed, the control queues the “is dryer empty” (display
iS, drYEr, EnPtY each for two seconds) prompting the user to
answer whether the machine is currently empty, pressing the Up
or Down keypads will toggle between yes and no. If the operator
selects “no” (display no), the control returns to the Idle Mode
display. If the operator selects “yes” (display YES) the control
will increment the Moisture Sensor Error counter and record the
error in the queue of the last eight machine errors and display the
Moisture Sensor Error (display EnoiSt), pressing the Back keypad will clear the error. The “is dryer empty” prompt will only
appear once a day unless machine power is cycled.
Fan Motor Centrifugal Switch Error
If the control attempts to turn on the fan motor and the fan motor
contactor is sensed closed but the Fan Motor Centrifugal Switch
fails to close, the control will go into the Cool Down portion of
the cycle, display an error message and turn on the audio signal.
Once the Cool Down portion of the cycle ends, the control will
continue displaying the error message until power is cycled or the
Back keypad is pressed.
DIP Switch/Harness Index Mismatch Er-
ror
On power up the control reads the Temperature Index Harness
value and compares that with the value of switch 1, switch 2 and
switch 3 on the DIP switch configuration. If the result is an invalid setup the control will not enter Idle mode and instead enter Error Mode. The control will ignore all user inputs and display an
error message. The machine must be powered down and the correct temperature index harness must be installed and/or the DIP
switch configuration must be corrected.
Moisture Sensor Error
When in Idle Mode, the control will begin to monitor the moisture sensor input. If the moisture sensor circuitry detects a load
present signal read consistently (every second) for a ten minute
