Troubleshooting: ERR2 - Motor Movement
Since the motor moves when you press speed up, focus on the optic sensor, its wire connections, and the
optic sensor wheel. If all seems well at the sensor, inspect the motor.
Optic Sensor
??? Optic sensor wheel - Make sure that the optic sensor wheel rotates securely, without wobbling, in the
middle of the optic sensor. Realign and tighten if necessary. If optic sensor wheel teeth are missing or
bent, replace the optic sensor wheel.
??? Optic sensor wires - Make sure that wires are inserted securely to the optic sensor and to the drive board.
Check wire continuity.
??? Optic sensor - Turn on unit power. Turn the motor flywheel with your hand. The optic sensor
indicator (LED10, drive board) should light. . If it does not light, and all parts above are
good, replace the optic sensor.
Motor
??? Motor arcing - Does the motor show signs of wear - irregular arcing, carbon dust?
??? Motor brushes - Do brushes show signs of irregular wear - cracks, dents, lines? Replace the
motor brushes.
??? M+ M- Wires - Make sure wires are connected properly.
Other
??? Display main IC - To ensure proper signal processing, press down on the main IC on the display
board, marked U5. .
??? Ribbon cable - Ensure that the ribbon cable is attached at the drive and display boards. Check cable
continuity.

The Steps for Newer Style Console Calibration
Locate the calibration area on the rear or underside of the console (a hole, near the console's center, that goes through to the electronics board. (This hole should not have a screw in it.)
Insert a pencil (eraser end), into the hole and feel around for the cal button (will click when pressed).
Press the button 2 times (with the pencil eraser). The first click should show CL11 in the console, the second click should show CL21.
If the process was done correctly, and CL21 appears in the console, you are in "calibration mode." The next few steps consists of pressing buttons on the console and observing settings. This will not require any other tools.
Press ENTER. CL22 should display in the TIME window and (??) in the SPEED window.
Press ENTER. CL23 should display in the TIME window and (??) in the SPEED window.
Press ENTER. CL24 should display in the TIME window and (??) in the SPEED window.
Press ENTER. CL25 should display in the TIME window and (??) in the SPEED window.
Press ENTER. CL26 should display in the TIME window. You should then see the letter "E."
Press ENTER. You should see "SS" or "55" in the console.
Push the STOP/START button. For safety, at this point, you should step off, or be off, the treadmill.
Push the ENTER button. The walking belt should start to move, accelerate to maximum speed, then stop on its own.
When the belt stops, the incline should self test by raising to its highest incline position, then lowering back down to its lowest position.
Once the incline test is complete, push the POWER button 2 times. The unit should shut off and the console should go completely blank. If this happens, the treadmill is done calibrating and is ready for use.
