CHAPTER 4: TROUBLESHOOTING 

4.2 Troubleshooting - No Resistance or Incorrect Resistance 

 

Symptom

1. The resistance is not adjustable during an exercise.   

             2. The resistance is reverse or much too heavy. 

 

Reason

: 

1.  The speed sensor wire is defective. 

2.  The console cable or ECB motor is defective. 

3.  The steel rope of the magnet system is not routed correctly. 

4.  The inside magnet is defective. 

 

   

Solution

   

1.  Check if the console shows RPM value. If it does not, refer to troubleshooting for NO RPM 

DISPLAYED in Section 4.1.   

2.  Remove the front shrouds. Turn on the console, and check the ECB motor. At resistance level 1, the 

head of the steel rope should point towards the top right side (around 45 degrees). If the head of the 

steel rope points toward the bottom or left side, the resistance will be reversed, adjust the head of the 

steel rope to the correct position. 

 

 

 

 

 

 

 

 

3.  Press the LEVEL UP key to adjust the resistance. 

a.  If the ECB motor does not move, the resistance will not be changed. The ECB motor or 

console cable is defective. Check the console cable connection at the ECB motor. Use a 

multi-meter to measure the voltage through the console cable. It should be 12VDC.   

b.  If there is no voltage present, the console cable is defective. Replace the console cable.   

c.  If the voltage is 12VDC, the ECB motor is defective. Replace ECB motor.
