Motor Lube Date
Access Level Required: ADMIN
Allows modification of the Date of Last Motor Lubri-
cation.
Auto Lube
Access Level Required: SERVICE
This setpoint accommodates those chillers that are
equipped with the optional Automatic Motor Lubrica-
tion hardware that automatically lubricates the motor
at regular intervals. Since chillers equipped with this
hardware don't require manual lubrication, the lubrica-
tion warnings displayed at 1000, 1200 and 1400 (safety
shutdown) operating hours since last lubrication are
unnecessary. Therefore, when the automatic lubrica-
tion hardware is present, this setpoint must be enabled.
With this setting, no lubrication warnings or safety
shutdown will occur. If disabled, as it should be when
not equipped with the automatic lubrication hardware,
the motor lubrication warnings and safety shutdown
will occur at the associated operating hours.
Shutdown
Access Level Required: SERVICE
If the Auto Lube Setpoint above is set to Disabled, the
Shutdown Setpoint is used to enable or disable the safe-
ty shutdown that occurs at 1400 operating hours since
last lubrication. The safety shutdown can be enabled or
disabled per the customer's preference. If enabled, the
safety shutdown will occur at the normal 1400 hours.
If disabled, a warning will be displayed but the safety
shutdown will not occur.
