Motor Cooling Coil Leak Protection
Access Level Required: SERVICE
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 indi-
cator 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 mo-
tor is 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 se-
rial communications.
Manual Baseline (Motor Bearing Vibration)
Access Level Required: SERVICE
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 par-
ticular units of measure. They are relative values. The
112
larger the number, the greater the magnitude of vibra-
tion represented. Values entered appear on this screen
as the Vibration Baseline values. A special password is
required.
Auto Baseline (Motor Bearing Vibration)
Access Level Required: SERVICE
Used to run the auto baseline routine. Only allowed af-
ter the chiller has been running for greater than 2 min-
utes. The vibration level of each bearing is indepen-
dently 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. At the comple-
tion 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 repre-
sented. A special password is required.
