Description
Displays the enabled Shaft End and Opposite End motor bearing temperatures. Any
RTD input that registers as an open RTD, is considered invalid and displays as XXX.X.
When the Bearing Temperature Protection Setpoint is set to Disable, no temperatures
are displayed and the heading, text and data boxes do not appear.
Displays the Shaft End and Opposite End vibration values. The vibration values are not
in any particular units of measure and are relative values. The larger the number, the
greater the magnitude of vibration represented. When the Motor Vibration Protection
Setpoint is set to Disabled, no vibration values are displayed and the heading, text and
data boxes do not appear.
Displays the Shaft End and Opposite End vibration values established during the
running of the auto baseline routine using the Auto Baseline key or by manual entry
using the Manual Baseline key. The vibration baseline values are not in any particular
units of measure and are relative values. The larger the number, the greater the
magnitude of vibration represented. These values also create the High Vibration
Shutdown and High Vibration Warning thresholds.
Note: If the calculated value exceeds the minimum and maximum limits of the
Shutdown (2.0 to 30.0) or Warning (1.0 to 15.0) threshold, the threshold is set to the
respective upper or lower limit.
• Shaft End High Vibration Warning - Shaft End Vibration Baseline X2
• Shaft End High Vibration Warning Default - Shaft End Vibration Baseline X2
• Opposite Shaft End High Vibration Warning - Opposite End Vibration Baseline X2
• Opposite Shaft End High Vibration Warning Default - Opposite End Vibration
Baseline X2
• Shaft End High Vibration Shutdown - Shaft End Vibration Baseline X3
• Shaft End High Vibration Shutdown Default - Shaft End Vibration Baseline X3
• Opposite Shaft End High Vibration Shutdown - Opposite Shaft End Vibration
Baseline X3
• Opposite Shaft End High Vibration Shutdown Default - Opposite Shaft End
Vibration Baseline X3
These automatically derived values can be overridden by manually entering a
threshold on the Motor Setpoints screen using the Vibration Setup key.
If no baseline values are entered, by either the auto baseline routine or manual entry,
the message WARNING – MOTOR – BEARING VIBRATION BASELINE NOT SET
appears and the baseline values are set to X.X while this message is displayed. When
the Motor Vibration Protection Setpoint is set to Disabled, no baseline vibration values
are displayed and the heading, text and data boxes do not appear.
Only appears when the auto baseline routine is running. Displays the time remaining
in the 1 hour auto baseline routine.
