DMP OPL Features
DIP Switch Settings
The DMP has an 8 position DIP switch bank that is
accessible from the back of the control board. By
switching these DIP switches, it is possible for the
operator to customize the display and some of the
operating features of the tumbler.
DIP Switch Functions Explained
1. Tumbler Type: This DIP switch selects the type
of tumbler, i.e., OPL or Coin.
2. Temperature Units: Selects ºF or ºC for the
temperature display. Factory setting is for ºF.
3. Local/Remote Reversing: Preset at the factory;
usually for local reversing. Remote reversing for
use with Reversing Timer Board only.
4. Empty: Preset at the factory; always ON.
5. Empty: Preset at the factory; always ON.
6. Buzzer Timer: This DIP switch determines the
length of time that the end of cycle buzzer will
remain on. “OFF” indicates that the buzzer will
sound for 5 seconds when the drying cycle is
completed. “ON” indicates that the buzzer will
sound continuously until the STOP button is
pressed, or the loading door is opened.
7. Safety Tumble, Display Count, or Pay: If DIP
switch #1 is set for OPL, then DIP switch #7 in
the ON position enables the safety tumble. If DIP
switch #1 is set for Coin, then DIP switch #7 in
the display of “PAy,” to indicate that coins are
needed to run the tumbler.
8. Programming: This switch enables or disables
the programming feature and should normally be
in the OFF position.

counterclockwise time within the range of
30-120 seconds.
10. Press the REV button to save these settings and
leave DIP switch #3 in the ON position and flip
DIP switch #8 to the OFF position.
When the DMP controller is retrofitted to an existing
tumbler with the reversing feature, off board reversing
will be required and DIP switch #3 on the DMP must
be in the OFF position and the DMP must be
connected to the Reversing Timer Board for proper
operation. The DMP settings for clockwise, dwell, and
counterclockwise times are no longer valid when used
with the Reversing Board. Instead these settings are
made on the Reversing Timer Board.

Rotation Sensor
The rotation sensor must “read” the key on the basket
shaft or pulley. The sensor must be set approximately
1/4 inch from the key or pulley. Look for the light on
the sensor to come on as the key passes on the sensor;
this is a correctly operating sensor. If no light appears,
either the sensor is out of range or the key/pulley or the
sensor is bad. In addition, if the light stays on
continuously, then the sensor is too close to the
component or the sensor is bad.
Safety Tumble/Anti-Wrinkle
At the end of the cool down cycle, the tumbler will
stop and display “END.” The DMP control will
automatically rotate the basket for 5 seconds every
2 minutes for a total of 20 minutes, until some
function of the tumbler is activated/deactivated by the
user.
Operational Check for the Board Diagnostics
1. “dor” indicates that the loading or lint door is
open.
2. Cycle the tumbler to check if the buzzer activates.
3. “P-F” indicates that the thermistor is short
circuited or open circuited.
4. “bbt” indicates a broken belt condition or a faulty
rotation sensor. (Only available on tumblers with
the rotation sensor.)
5. Hold the START button to display the drum
RPMs; the display will read “r##” where ## are
the RPMs. (Only available on tumblers with the
rotation sensor.)
Ignition Control Operation
Power Up
After 24 VAC is applied to the ignition control pins
24V and GND, the Diagnostic LED on the ignition
control will turn orange/yellow. If a fault is detected
the ignition control will enter Lockout Mode. If no
faults are detected, the Diagnostic LED will turn
Green and the ignition control will enter Standby
Mode.
Standby Mode
While in Standby Mode, the ignition control will
continually monitor the system for faults. Once
24VAC is applied to terminals TH and GND on the
control, the ignition control will enter Start Up Mode.
Start Up Mode
During Start Up Mode, the ignition control will
monitor the system for faults and begin the ignition
sequence. If no faults are present, the ignition control
will begin the ignition sequence by entering an 18
second waiting period. During this time the Green
LED on the ignition control will switch between Red
and Green, before maintaining a Green color.
After the waiting period, the ignition control will turn
on the igniter and gas valve. The igniter will remain on
until a flame is sensed, or up to 10 seconds.
Once a flame has been sensed the ignition control will
stop sparking, the gas valve will remain on and
ignition control will enter Run Mode.
If a flame is not sensed, the ignition control will then
begin two additional retrials for ignition. The ignition
control will re-enter the 18 seconds waiting period
before the ignition control makes another attempt at
ignition. If the three attempts at ignition fail, the
ignition control will enter Lockout Mode.
Run Mode
While in Run Mode the ignition control leaves the gas
valve on, monitors the flame signal, and leaves the
igniter off.
If a flame signal is lost during Run Mode, one
additional retrial for ignition will take place within one
second. The ignition control will restore the spark for
approximately 10 seconds. If the ignition re-attempt
fails, the ignition control will enter Lockout Mode.
The ignition control will remain in Run Mode until
24VAC is removed from terminals TH and GND on
the control.

Termination of Flame
The flame will go out when power is removed from
ignition control. The ignition control will turn off the
gas valve and enter Standby Mode.
Lockout Mode
When Lockout Mode is entered, the ignition control
will remove power to the gas valve, the igniter will
turn off, the Lockout/Reset Light will turn on, and the
Diagnostic LED will display the appropriate Error
Code.
Lockout Manual Reset
Lockout Mode is cleared by pressing an external reset
switch for three seconds. The ignition control will
clear all error codes and enter Standby Mode. During
Lockout Manual Reset, the Diagnostic LED on the
ignition control flashes red and orange, and the Reset
Light remains on until the ignition control is reset.
After the Reset Light turns off, stop pressing the
switch. Holding the reset for three seconds after
lockout has been cleared will cause a fault and result in
entering Lockout Mode again.
System Tests
The following system tests are performed during
normal operation. System tests are performed at a
minimum of every 24 hours.
Low Voltage Detection
If the voltage between terminals TH and GND on the
control is below 18.75VAC +/- 0.75VAC for more than
3 seconds the ignition control will turn off the gas
valve and will not attempt to spark. The Diagnostic
LED will display Error Code 5. The ignition control
will not enter Lockout Mode if a low voltage condition
is detected, but will enter Standby Mode and wait for
the low voltage condition to be cleared.
If the voltage between terminals TH and GND on the
control rises above 19.75VAC +/- 0.1VAC for at least 3
seconds, the ignition control will then enter Start Up
Mode.
Low Voltage Detection test is disabled during Run
Mode.
Gas Valve
The ignition control verifies that the gas valve is
connected. Failure of this test results in the ignition
control entering Lockout Mode with the Diagnostic
LED displaying Error Code 2.
Flame Probe Tests
Unexpected Presence of Flame
The Unexpected Presence of Flame test is performed
when no flame is expected. Failure of this test results
in the ignition control entering Lockout Mode with the
Diagnostic LED displaying Error Code 3.
Flame Monitoring
During the Flame Monitoring test, the flame is
checked to ensure the gas is being burned when the gas
valve is on. Failure of this test will result in the
ignition control entering Lockout Mode with the
Diagnostic LED displaying Error Code 3.

Maintenance
Daily
1. Inspect the area surrounding tumblers, remove all
combustible materials, including lint, before
operating the machines.
2. Check cylinder for foreign objects to avoid
damage to clothing and equipment.
3. Clean lint from lint compartment and screen to
maintain proper airflow and avoid overheating.
a. Open the lint panel.
b. Remove all accumulated lint in the lint
compartment area. Lightly brush any lint that
may be left on the lint screen. Lint left in the
lint compartment is drawn back onto the lint
screen and will restrict proper air circulation.
c. Be sure the lint screen is not torn. If it is,
replace immediately. A torn lint screen allows
lint to pass from the tumbler to the ductwork
system, thus creating a restriction to air
circulation.
d. The lint screen is designed to completely
cover the entire opening in the lint screen
panel. Be sure that it does so. Excessive gaps
between the lint screen and the lint screen
panel allow lint to pass into the ductwork
system.
e. Carefully wipe any accumulated lint off of the
cabinet high limit thermostat and thermistor.
Failure to do so will allow a buildup of lint in
this area to act as an insulator, causing the
tumbler to overheat. Refer to Figure 7.
f. Replace the lint compartment panel on the
tumbler ensuring a tight fit, and lock if
applicable.
Figure 7
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.
• Never start the tumbler with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the tumbler is properly grounded. W002
WARNING
To reduce the risk of serious injury, do not
open the lint panel while the tumbler is in
operation. Before cleaning the lint screen,
open tumbler door and allow cylinder to
completely stop. W410
