“MOTOR – LACK OF BEARING LUBRICATION”
(Software version C.OPT.11.02.300 (and later)).
The Operating Hours Since Last Motor Lubrication has
exceeded 1400 hours (the greater of either Motor #1
Operating Hours or Motor #2 Operating Hours is used
for this calculation). This message replaces “Warning
– Motor Bearing Lube Required” above. This safety
shutdown remains in effect until the Operator places
the COMPRESSOR Switch in the Stop-reset (O) posi-
tion and enters his/her initials, name or user ID in Op-
erator Access Level (or higher) using the Motor Lube
Acknowledge key on the Motor Lubrication Screen.
tions. This entry implies both motors were lubricated.
The date and time of this entry is automatically logged
as the “Date of Last Motor Lubrication” and “Time of
Last Motor Lubrication”. It also resets the “Operating
Hours Since Last Lubrication” to zero. The date this
warning occurs is stored as the “Date of Last Motor
Lubrication Warning or Fault”. If the SHUTDOWN
setpoint on the Motor Lubrication Screen is disabled,
this message will be displayed as a warning but the
safety shutdown will not be performed.

the Clear Faults button.

sor 1 was running. The chiller can be started after the
PRV end switch has closed and the Operator presses
the Clear Faults button.
