Not shown when Motor Vibration Protection Setpoint on Motor Details
screen is set to Disabled.
Allows a Service Technician to program the High Vibration Shutdown (2.0
to 30; default Baseline X3) and Warning (1.0 to 15; default Baseline X2)
thresholds for the Shaft End and Opposite Shaft End bearings, along with
the desired delays (Shutdown - 0 to 30 seconds, default 15; Warning - 0 to
120 seconds; default 30). The vibration thresholds are not in any particular
units of measure. They are relative values. The larger the number, the
greater the magnitude of vibration represented.
The thresholds used for shutdown and warning are either the values
entered by this Vibration Setup Setpoint or the values derived from the
Vibration Baseline Setpoints. The values used by the software depend
upon the sequence in which the setpoints are entered. If Vibration
Baseline values are established (on the Motor Details screen with either
the Manual Baseline key or the Auto Baseline key) after thresholds have
been entered with the Vibration Setup Setpoint, the baseline derived
Shutdown and Warning thresholds override the thresholds entered with
the Vibration Setup Setpoint. Thresholds entered with this Vibration Setup
Setpoint, after baseline derived Shutdown and Warning thresholds are
entered, override Baseline derived values. The active threshold values
are displayed in the Motor Bearings High Vibration Shutdown and High
Vibration Warning data boxes on this screen.
The Vibration Baseline values from which the Vibration Shutdown and
Warning thresholds are derived, are displayed on the Motor Details
screen.
JCI Service The thresholds are calculated from the Baseline values.
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
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.
