OVERVIEW
This screen displays the orientation of the magnetic
bearing axes relative to the compressor driveline simi-
lar to the MBC Screen. Additional pertinent param-
eters transmitted to the control panel from the Mag-
netic Bearing Controller (MBC) are displayed on this
screen. Many parameters are shown in the diagram in
the locations they represent. The left end of the motor
shaft graphic represents the Impeller End Bearing. The
right end of the motor shaft graphic represents the Op-
posite Impeller End Bearing.
DISPLAY ONLY
Z1 Temperature
Displays the temperature measured at the impeller end
bearing assembly.
VW13 Vibration
Displays the vibration amplitude at rotational frequen-
cy, radially at the impeller end bearing position sen-
sors.
VW24 Vibration
Displays the vibration amplitude at rotational frequen-
cy, radially at the opposite impeller end bearing posi-
tion sensor.
Z2 Temperature
Displays the temperature measured at the opposite im-
peller end bearing assembly.
Z12 Vibration
Displays the vibration amplitude for specific frequen-
cies measured axially by the position sensors.
