PROXIMITY PROBE CALIBRATION SCREEN

FIGURE 17 - PROXIMITY PROBE CALIBRATION SCREEN (CHILLERS WITH J OR H3 COMPRESSORS)

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.
DISPLAY ONLY
High Speed Thrust Bearing Proximity Position
Displays the distance between the high-speed thrust

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
displayed value includes offset pressure derived from
auto-zeroing during the System Prelube. If either of the
transducers used to calculate this differential 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.
