Enables and disables the Motor Bearing Vibration protection feature.
When set to any setting other than Disabled, the respective vibration
values are enabled and displayed. The HIGH BEARING VIBRATION
fault and warnings occur when the programmed thresholds for those
conditions are reached. The settings are:
• Disabled: Disables the Bearing Vibration Protection feature.
No bearing vibration values are displayed and the heading, text
and data boxes do not appear. The High Bearing Vibration Fault,
Warning and Baseline Not Set Warning will not occur. This setting
JCI Service
is used when the motor is not equipped with bearing vibration
sensors or if is desired to disable the feature for service reasons.
This is the default setting.
• Rolling element: Enables and displays the Bearing Vibration
Protection feature. Displays the Shaft End and Opposite Shaft End
vibration values as reported by the vibration sensors via the Motor
Monitoring Board serial communications. The Vibration Baseline
values, created by either manual entry or by running the auto
baseline routine are shown, along with the Auto Baseline and Auto
Baseline Setpoint keys.
Enables the type of leak protection device being used to detect a leak of
the motor cooling coil. When set to any setting other than Disabled, an
LED status indicator is displayed and the Motor Cooling Coil safety fault
will occur when the sensor indicates a leak. The settings are:
• Disabled: Disables the Motor Cooling Coil Leak Protection feature.
The status LED and text do not appear. The Motor Cooling Coil
Leak fault will not occur. This setting is used when the motor is
JCI Service
not equipped with a leak detector or if it is desired to disable this
feature for service reasons. This is the default setting.
• Optical: Enables the optical sensor digital input and displays the
leak status, as reported by the optical leak sensor, via the motor
monitoring board serial communications.
Float: Enables the float sensor digital input and displays the
•
leak status, as reported by the float leak sensor, via the motor
monitoring board serial communications.
Used to manually enter a vibration baseline value (0.1 to 5; default 2) for
the Shaft End and Opposite Shaft End bearings. The vibration values are
not in any particular units of measure. They are relative values. The larger
JCI Service
the number, the greater the magnitude of vibration represented. Values
entered appear on this screen as the Vibration Baseline values. A special
password is required.
Used to run the auto baseline routine. Only allowed after the chiller has
been running for greater than 2 minutes. The vibration level of each
bearing is independently averaged for 1 hour at 1 minute intervals while
the chiller is running. While the routine is running, the time remaining in
the 1 hour routine is displayed as auto baseline time left on this screen.
JCI Service
At the completion of the routine, the derived values appear on the screen
as the Vibration Baseline values (0.1 - 5; default 2). The vibration values
are not in any particular units of measure. They are relative values. The
larger the number, the greater the magnitude of vibration represented. A
special password is required.
