Incorrect speed sensor connection on treadmill brands such as Carl Lewis, Roger Black, Bremshey, DKN Technology, Proform, Weslo and other major UK brands

One of the rules of good design is to make each connector different from another, to avoid confusion during assembly.

Unfortunately this is not always the case, some motor control boards mounted on some treadmill brands such as Carl Lewis, Roger Black, Bremshey, DKN Technology, Proform, Weslo and other major UK brands have an optical speed sensor with a 3-pin connector.


3-pin optical sensor

Also the incline motor signal feedback connector is composed of 3 pins, so on the TRC treadmill motor control boards... and PF... there is a possibility of error in connecting the INCLINE motor encoder into the male connection on the board which is destined  for the optical sensor (they are the same). For example on the DKN T-980, which uses the PF-906 and optical sensor.
In case of wrong connection the equipment gives an inclination error and does not operate at the correct running belt speed.

Need replacement parts?
  1.  PF-906 controller
  2.  optical treadmill speed sensor with a 3-pin connector
  3.  speed sensors (2 pin, 3 pin, 4 pin)
  4. Treadmill controllers 
  5. other parts for treadmill, exercise bikes & fitness equipment
