           Speed Sensor Test  (TPS Series/ Z Series)

 

 

 

      

            

This test will expose the technician to a  potential  

pinch hazard. Exercise caution when performing test.             

 

1. Remove the motor cover and verify that the speed sensor is 

between 1/8” to 1/4” away from the roller pulley (TPS 
Series, Z series). 
 

2. Turn the flywheel on motor so that there is belt movement. 

Verify that the speed LED blinks on the lower board when 
there is movement at the speed sensor. 

 
3. If the Speed LED does not blink, 

replace the speed sensor

. 

          

Optical Sensor Test (TCS Series

) 

 
On the optical sensor, measure DC volts between pins 2 and 
3 of the speed sensor plug while plugged into the lower 
board.  There should be a reading of 5VDC(on) to below 
1VDC(off). Readings of 1.90VDC or higher during the off 
cycle could cause the RPM LED to not cycle and will result in 
a speed error. 
 
If this speed sensor test is successful 

replace the lower 

board. 

If the speed sensor test fails 

replace the speed 

sensor.
