Question about Precor C954i Commercial Treadmill
Error 22 indicates that the drive motor (running belt) has been instructed to start, by either
manual or program control, and the monitoring system has not received any response from the
speed sensing system indicating that the drive motor has started
Possible Causes 1. The treadmill utilizes an optical (infrared) speed sensor and the line of sight between the speed sensor and the speed sensor target is obstructed. 2. Drive motor brushes are bad. 3. The speed sensor position relative to the speed sensor target is incorrect. 4. The speed sensor potentiometer adjustment is incorrect (when equipped). 5. The speed sensor is inoperative. 6. The lower PCA is bad. 7. The lower PCA to upper PCA interconnect cable is bad. 8. The upper PCA is bad
Error 45 :The lift control system has detected that the lift is moving in the opposite direction of the issued
Possible Causes 1. Lift Motor hysteresis. 2. Bad lower PCA
Possible Remedies 1. This error would typically happen when the lift was already in motion (typically downward) when a lift command in the opposite direction (lift up) was issued. Some motors exhibited a very long turn around time and the lift motor would still be moving in the original direction (downward) while the control system was attempting to move the lift in the opposite direction. If the error 45 condition is persistent, replace the lift motor. 2. This is a very rare condition, if the lift moves in the opposite direction of the issued lift command, replace the lower PCA lift command.
