Proximity probe calibration screen
Figure 38: Proximity probe calibration screen
This screen displays a cutaway view of the chiller compressor, revealing the Proximity Probe sensor
and provides the capability of calibrating the Proximity Probe sensor.
Note:

Field/LED name
Description
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 position. This value is defined at the
conclusion of a calibration 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 calibration. 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.
