On the display
The control center shows Warning - Motor - Bearing vibration baseline not set. The manual lists it among the warning messages for this chiller. While the message is displayed, the vibration baseline values are set to X.X.
What it means
The shaft end and opposite shaft end motor bearing vibration baseline values have not been entered on the motor details screen — neither by the auto baseline routine nor by manual entry. The message is displayed until both baseline values are present. While it is displayed, the manual states that the vibration baseline values are set to X.X.
Why it appears
- The shaft end and opposite shaft end motor bearing vibration baseline values have not been entered on the motor details screen — no auto baseline routine has been run and no manual entry has been made.
What to check
- Open the motor details screen on the control center.
- Check the vibration baseline values for both motor bearings — the shaft end and the opposite shaft end; while the warning is displayed, they are set to X.X.
- Enter both baselines manually, using the manual baseline setpoint on that screen.
- Alternatively, set them automatically with the Auto Baseline key on that screen, which runs the auto baseline routine.
- Confirm that both the shaft end and opposite shaft end baseline values are now entered — the warning is displayed only until both values are present.
Setpoints and thresholds
- Manual baseline setpoint — on the motor details screen; entering the baseline values here sets them manually.
Reset and restart
No separate reset action is described for this warning. It is displayed until both the shaft end and opposite shaft end motor bearing vibration baseline values are entered on the motor details screen — either manually with the manual baseline setpoint or automatically with the Auto Baseline key
. Once both values are entered, the message is no longer displayed.
Questions engineers ask
What does Warning - Motor - Bearing vibration baseline not set mean on a YORK YK chiller?
It means the shaft end and opposite shaft end motor bearing vibration baseline values have not been entered on the motor details screen. While the message is displayed, the baseline values are set to X.X.
How do I clear the bearing vibration baseline warning on a YORK YK?
Enter both baseline values on the motor details screen — manually with the manual baseline setpoint or automatically with the Auto Baseline key. The warning is displayed until both baselines are entered.
Where are the motor bearing vibration baselines entered on a YORK YK?
On the motor details screen of the control center. You can type the values with the manual baseline setpoint or press the Auto Baseline key on that screen to run the auto baseline routine.
Why does the YK show X.X for the motor vibration baselines?
The manual states that the vibration baseline values are set to X.X while this warning is displayed. Once both baselines are entered, the warning ends and the values are shown this way no longer.
