P203 Auto-Lubrication System
A new version of the
auto-luber, the Lincoln P203 allows the OptiView pan-
el to control the lubrication timing which allows the
lubrication to only be applied while the motor is not
operating. The P203 also has a low grease level switch
that is monitored by the OptiView to provide a mes-
sage to the user that the grease reservoir must be filled.
The P203 will perform a lubrication at 900 hours of op-
eration since the last lubrication if the motor is stopped.
If the chiller runs 1400 hours since the last lubrication
without stopping, a cycling fault will occur, the chiller
will shut down and the bearings will be automatically
lubricated. The chiller will then restart at the comple-
tion of the lubrication. Chiller startup is inhibited dur-
ing the auto-lube process.
Sleeve Bearings
Motors with sleeve bearings use oil
which does not require changing as often as motors
with ball bearings that require grease. Additional mes-
sages have been added to support Sleeve Bearings Lu-
brication.
Appropriate messages for each of the lubrication
choices are displayed and user actions logged.
Warning – Motor Oil Change Sug-
gested
is displayed at 4000 operat-
ing hours since the last motor lubrication.
A completed lube acknowledgement will clear the
message.
Warning – Motor Oil Change Re-
quired
is displayed at 5000 operat-
ing hours since the last motor lubrication.
A completed lube acknowledgement will clear the
message.
Warning – Lack of Motor Oil Change
is displayed at
6000 operating hours since the last motor lubrication.
A completed lube acknowledgement will clear the
message. If the Shutdowns setting is set to En-
abled, this third message will be treated as a Safe-
ty Fault and will therefore shut down the chiller
until the motor lubrication is performed and ac-
knowledged.
ISOLATION VALVES
The control of Isolation Valves is changed to the fol-
lowing LTC I/O board locations.

HEAD PRESSURE AND HEAT RECOVERY
The minimum access level for the Head Pressure Con-
trol and Heat Recovery Screens has been changed to
Operator.
CHILLER STYLE
Program additions have been made to support the high
temperature heat pump compressors Style G/U1-2 and
Style G/U3-4,7.
ERASE BRAM
The “Erase All BRAM” button has been added to the
Diagnostics Screen. The “Erase All BRAM” button is
only visible when the following conditions are true:
• Access Level is Admin
• Chiller is Stopped
• Panel Switch is OFF
Selection of the “Erase All BRAM” button displays
a confirmation box with the string “Erase All BRAM
and reboot? If “Yes” is selected ALL data stored in the
OptiView BRAM will be erased and then the panel
rebooted. This includes the Sales Data so, this func-
tion must only be used when factory Product Technical
Support advises to do so and issues the Admin pass-
word to allow the function.
