SECTION 2 – OPTIVIEW CONTROL CENTER
Overview
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. The appearance of this screen is the same for
compressor #1 and compressor #2.
Requires a login access level of SER-
VICE. Service Technicians refer to YORK

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 pump oil
pressure transducer (compressor bearing input) and the
sump oil pressure transducer. If either of the transduc-
ers 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
