Preliminary Control Information
Power-Up Mode
When power is applied to the tumbler the control will
enter Ready Mode, unless a cycle was in process prior
to a disruption of power. If a power disruption is less
than 5 seconds, with a cycle in process, the control
will enter Run Mode once power is restored and
continue the cycle. If a power disruption is more than
5 seconds, with a cycle in process, the control will
enter Start Mode once power is restored.
If the dry time dipswitch settings have not changed
from the factory default, the IN USE LED will flash
two to five times, depending on model.
Ready Mode
In Ready Mode, the control waits for the vend to be
satisfied before entering Start Mode.
Start Mode
In Start Mode, the vend has been satisfied, but the
Start button has not been pressed. The IN USE LED
will be lit. The timer will not count down until the
Start button is pressed.
Run Mode
In Run Mode, the control is running a cycle. The IN
USE LED is lit.
Door Open Mode
In Door Open Mode, the control turns off the heater
and motor when the door is opened during a run
cycle. The timer will continue to count down time
and the IN USE LED is lit.
End of Cycle Mode
In End of Cycle Mode, a cycle is complete and the
IN USE LED is off. The control remains in this
mode until the door is opened or additional vend has
been satisfied.

Topoffs
Any time the control receives a coin drop pulse during
a cycle it will add the programmed dry time to the time
currently remaining in the cycle. The maximum cycle
time is 99 minutes, the control will not add time
beyond 99 minutes. The cool down time will not
change.
If the control receives a coin drop pulse during cool
down the IN USE LED will flash briefly to indicate the
coin input, the machine will exit cool down and it will
start heating. The cycle time will be equal to the
programmed dry time
Temperature Selector Switch
For five minutes after the control is powered up, there
is a diagnostic feature that allows the temperature
selector switches to be tested.
When the temperature selector is changed, the new
setting is displayed by flashing the IN USE LED as
follows:
High/Normal: 4 flashes
Medium/PP: 3 flashes
Low/Delicate: 2 flashes
No Heat: 1 flash
NOTE: To change dipswitch settings refer to
Installation Manual.
Error Codes
To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect electric power to the tumbler before servicing.
• Close gas shut-off valve to gas tumbler before servicing.
• Close steam valve to steam tumbler before servicing.

The minimum drying time is 0 minutes, and the
minimum cooling time is 2 minutes. The maximum
drying or cooling time is 60 minutes. The drying
temperature may be set from 100ºF (38ºC) to 185º/
195ºF (85º/91ºC). The drying time, cooling time, or
temperature may be modified during an operating
cycle.
If it is necessary to reset the drying and cooling times
for the current cycle, press STOP once to stop the
tumbler. Press STOP again to cancel the cycle.
If it is necessary to change programs during a current
cycle, press STOP once to stop the tumbler and press
STOP again to cancel the current cycle.

DMP Coin Features
Coin Keypad Interface
- START button to start or resume a cycle.
- TEMP button to select HIGH, MEDIUM, or LOW
temperature.
- Two hidden buttons to increment or decrement the
programmable time and temperature options.
Power-Up
Upon applying power to the tumbler, the display will
show “PAy” and the DRYING and COOLING LEDs
will be off until coins are deposited to increase the
tumbler run time. When time is displayed, the default
(LOW) temperature setting LED will be on until a
different temperature setting is selected.
Power Failure
If a power loss occurs during operation, a cycle will
not resume until the START button is pressed. To
cancel the remaining cycle, press the internal CLEAR
button.
Coin Operation
The tumbler run time is determined by the pre-
programmed run time per coin and the number of
coins deposited into the tumbler. The maximum time
that can be accumulated and displayed is 99 minutes.
The drying time is the difference between the run time
and the cooling time. The cooling time is pre-
programmed to be 2 to 5 minutes. The drying
temperature can be selected from LOW, MEDIUM, or
HIGH temperature settings by pressing the TEMP
button.
Coin Programming
The Coin board programming mode can only be
entered when “PAy” is displayed. DIP switch #7 must
be in the OFF position.
Programming is enabled by setting DIP switch #8 to
the ON position.
The programming mode is entered by pressing and
holding the CLEAR button for three seconds.
The programming follows the following parameter
order:
1. Tumbler run time per coin (DRYING),
COOLING time, HIGH temperature setpoint,
MEDIUM temperature setpoint, LOW
temperature setpoint.
2. An LED will be on to indicate which parameter is
flashing on the display.
3. The hidden front panel increment and decrement
keys are used to change the value.
4. The CLEAR button is used to recall the default
value.
5. The START button is used to step to the next
parameter.
6. After the last parameter, “End” will be flashing.
7. Press the START button one last time to store the
settings and exit the program mode.
8. “PAy” will be displayed.
9. If it is determined that the data did not program
correctly, the error message “E2F” will flash for
4 seconds, and then the default coin parameters
will be used.
The tumbler run time per coin is programmable for 1
to 20 minutes with the default preset to 10 minutes.
The cooling run time is programmable from 2 to
5 minutes with the default preset to 2 minutes.
The three temperatures setpoints are programmable for
100ºF (38ºC) to 185º/195ºF (85º/90ºC) with the
following default settings:
- HIGH equal to 185ºF (85ºC)
- MEDIUM equal to 150ºF (66ºC)
- LOW equal to 135ºF (57ºC)
Stop
When in the Coin mode, the tumbler will stop if the
tumbler door is opened while the tumbler is running. If
the CLEAR button, located behind the board, is
pressed, the tumbler will stop, the tumbler time will be
zeroed and the display will show “PAy.”
Coin Count
The unit will count the number of coins deposited.
Setting DIP switch #7 to the ON position will display
the coin count since it was the last reset.
To reset the count, press the CLEAR button and “00”
will be displayed.
If the coin count is greater than “999,” the display will
flash “999.”
Setting DIP switch #7 to the OFF position will return
the display to “PAy.”
