This screen displays a cutaway view of the chiller com-
pressor, revealing the proximity probe sensor and pro-
vides the capability of calibrating the proximity probe
sensor. It is only displayed when the "Compressor
Thrust Probe" is set for "Position" on the Operations
Screen.
Requires a login access for operation
instructions and explanation of all
programmable setpoints and displayed
values.

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
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.
