Dmp Opl Models - ALLIANCE CA050L Installation Operation & Maintenance

Operating Instructions
9. Use the Up/Down arrows to change the 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 tumble dry-
er 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counterclockwise times are no longer valid when used with the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 Revers-
ing 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 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 tumble dryer 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 tumble dryer 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 tumble dryer 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 tumble dryers with the rotation
sensor.)
5. Hold the START button to display the drum RPM's; the dis-
play will read "r##" where ## are the RPM's. (Only available
on tumble dryers with the rotation sensor.)
