Alliance Laundry Systems 25, P/N 70400201 Rotation Sensor, Safety Tumble/Anti-Wrinkle, Operational Check for the Board Diagnostics

Operating Instructions

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 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.
