Motor lubrication screen
Figure 46: Motor lubrication screen
This feature provides an indication when the compressor motor lubrication is required. The
lubrication requirement and notification is based on the operating hours since last motor
lubrication.
There are up to three levels of notification, each indicating an increasing level of urgency:
WARNING – MOTOR BEARING LUBE SUGGESTED is displayed when the hours exceed 1000 hours.
If there is no response, WARNING – MOTOR BEARING LUBE REQUIRED is displayed when the hours
exceed 1200 hours.
If there is still no response, a safety shutdown is performed when the hours exceed 1400 hours and
Motor – Lack Of Bearing Lubrication is displayed.
Refer to
Display messages for details of these messages.
To provide a record of when a motor lubrication is performed, the Operator enters his/her initials,
name or user ID using the MOTOR LUBE ACKNOWLEDGE key. The date and time of this entry is
automatically logged as the Date of Last Lubrication and Time of Last Lubrication. This also clears
any motor lubrication warning or safety that is in effect and resets the operating hours since last
lubrication to zero.
This lubrication notification and shutdown feature can be enabled or disabled based on the
customer’s preference using the AUTO LUBE and SHUTDOWN keys.
