Motor lubrication screen
Figure 57: 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 LUBE SUGGESTED
appears when the operating hours since the last lubrication are
200 less than the Motor Lubrication Required period. If there is no response,
WARNING – MOTOR
BEARING LUBE REQUIRED
appears when the operating hours since the last lubrication exceed the
Motor Bearing Lube Required period. If there is still no response, a safety shutdown (Motor – Lack
of Bearing Lubrication) is performed when the operating hours since the last lubrication exceed
the Motor Lube Required period plus 200 hours. See
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.
