“MOTOR – LACK OF BEARING LUBRICA-
TION”
(Software version C.MLM.11.02.xxx (and later) or
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.
Refer to the Motor Lubrication Screen for entry in-
structions. This entry implies both motors were lubri-
cated. 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”. With software
version C.OPT.11.03.01.004 (and later), if the SHUT-
DOWN setpoint on the Motor Lubrication Screen is
disabled, this message will be displayed as a warning
but the safety shutdown will not be performed.
“COMPRESSOR 1 PRV NOT FULLY CLOSED”
(Software version C.OPT.11.03.01.004 and later)
The chiller (both compressors) has shutdown because
compressor 1 Pre-rotation vanes have not fully closed
(as indicated by the PRV end-switch) while compres-
sor 2 was running. The chiller can be started after the
PRV end switch has closed and the COMPRESSOR
switch is placed in the Stop-reset (O) position.
“COMPRESSOR 2 PRV NOT FULLY CLOSED”
(Software version C.OPT.11.03.01.004 and later)
The chiller (both compressors) has shutdown because
compressor 2 Pre-rotation vanes have not fully closed
(as indicated by the PRV end-switch) while compres-
sor 1 was running. The chiller can be started after the
PRV end switch has closed and the COMPRESSOR
switch is placed in the Stop-reset (O) position.
