Error Codes

Cybex provides error code descriptions for your information. Cybex recommends that these errors be addressed by a qualified service technician. These codes notify you of a problem condition and errors which jeopardize safety will shut the treadmill down. The codes also help to indicate the part of the treadmill most likely to be causing the problem.

ERROR 1: No Speed Signal at Startup

ERROR 2: Excessive Current Draw

ERROR 3: Loss of Speed Signal

ERROR 50: Overspeed (stored as ERR 6)

ERROR 70: Loss of NOVRAM Information (stored as ERR 7)

If you have a problem that interrupts an important operational area of the treadmill, you may see one of the above error codes displayed in the control panel. If an Error Code is generated during operation, the treadmill's drive motor will stop. In order to restart the treadmill, the Error Code must be cleared by cycling the power to the machine by switching the ON/OFF switch to “OFF” for five seconds and then switching it back “ON” again. Should a code reappear soon after cycling off, then on again, report the problem to your Cybex dealer, authorized Cybex service representative or directly to Cybex Technical Support.

ERROR 1: No Speed Signal at Startup

This error code usually occurs only during start-up and indicates that the computer in the control panel is not receiving any indication of motor speed.

To isolate the source of this problem, you need to determine whether the drive motor tried to start up and did rotate or whether it never came on at all.

If the drive motor (and running belt) rotates, even if only for a second or so, the error code usually indicates that the speed sensor is malfunctioning. The quick way to check this is to remove the motor cover and the front panel to witness the SPEED LED on the motor control board. If it blinks when the flywheel is rotated by hand, the problem is most likely the console cable. After that, suspect the lower board and then the display board. This signal can also be seen on a diagnostic LED of the display board.
