FIGURE 19 - PROXIMITY PROBE CALIBRATION SCREEN

OVERVIEW
This screen displays a cutaway view of the chiller com-
pressor, revealing the Proximity Probe sensor and provides
the capability of calibrating the Proximity Probe sensor.
Requires a login access level of SERVICE.
Service Technicians refer to the OptiView
Control Center - Service Instructions
(Form 160.76-M1) for operation instruc-
tions and explanation of all programmable
setpoints and displayed values.
DISPLAY ONLY
High Speed Thrust Bearing Proximity Position
Displays the distance between the high-speed thrust
collar and the Proximity Probe that is used to measure
the position.
High Speed Thrust Bearing Proximity
Reference Position
Displays the presently defined offset reference posi-
tion. This value is defined at the conclusion of a cali-
bration sequence.

Oil Pressure
Displays the pressure differential between the high
side oil pressure transducer (compressor bearing input)
and the low side oil pressure transducer (oil sump). The
oil pressure must be at least 25 PSID during the cali-
bration. The displayed value includes offset pressure
derived from auto-zeroing during the System Prelube.
If either of the transducers used to calculate this differ-
ential is out of range, the display field will show XX.X.
Calibration in Progress (LED)
Indicates that the calibration sequence is in progress.
Calibration Messages
These are text messages which step the user through
the calibration process and indicate its success or
failure.
