Verify that the tension wire is
connected to the brake and has not
failed.
Check the wheel/tension wire
orientation (see photo of ECB Motor

- Page 3 PPENDIX ECB Motor Damage If appropriate installation steps are not followed while installing the ECB motor, the tension wire bracket and/or internal motor gears can become damaged. If the internal gears are damaged, a ticking or clicking noise may come from the motor. The photo below shows a damaged tension wire bracket.
- Page 4 Magnetic Brake Position The photo below shows the gap between the orange block and the bottom of the ECB (flywheel) track. When the unit is at the highest resistance level, the gap should be 1-2 mm. If the gap is larger than 1-2 mm, the resistance will be higher than normal. Adjust the cable to the correct gap range.
- Page 5 ECB Motor Replacement Procedure Required Tools: Phillips screwdriver • • Needle nose or bent nose pliers Follow these steps to replace the ECB motor: 1. Turn off and unplug the unit. 2. Using a screwdriver, remove the appropriate covers to access the ECB motor. 3.
- Page 6 7. Use a screwdriver to attach the motor to the frame (reuse the screws that were removed in step 3). (The motor may continue to adjust as you complete this step.) : After completing step 7, wait for one full minute before beginning step 8. This ensures MPORTANT the motor will complete any final adjustments before you reinstall the tension wire.
- Page 7 11. Reattach the wheel to the motor: Rotate the black wheel clockwise until there is no slack in the tension wire. It is important • to orient the wire correctly, looping down and then up around the wheel. The wire’s path is illustrated by the red arrow in the photo below.
- Page 8 13. Test the unit. When the cable is fully extended against spring tension, the resistance should be at • minimum (see photo below). When the cable is not extended, the resistance should be at maximum. • Note: The pulley completes just over half a (counter-clockwise) rotation from minimum to maximum resistance.
