SECTION 2 - OPTIVIEW CONTROL CENTER INTRODUCTION
Pre-rotation Vanes Position
Displays the Pre-rotation Vane position as a value be-
tween 0 and 100%.
Output Current
Displays the average of the 3-phase output current to
the motor. Value is provided by the MV VSD.
Input Voltage
Displays the average of the 3-phase input voltage to the
MV VSD. Value is provided by the MV VSD.
VSD Cooling Fans Output (LED)
Illuminates when the VSD cooling fans are being com-
manded to run.
Precharge Relay Output (LED)
Illuminates when the pre-charge relay is commanded
to energize.
Output Current (Phase A, B, C)
Displays the three phases of output current to the motor.
DC Bus Voltage (Phase A, B, C)
Displays the three phases of DC Bus voltage
MV VSD Model
Displays the model number as received from the MV
VSD. The model number is displayed as a number rep-
resenting the horsepower rating (ie; 1500HP). It is de-
rived from the Motor Rated Voltage and Programmed
Drive Current values received from the MV VSD ac-
cording to the following table. If this results in a model
that is not defined in the lookup table, the model num-
ber is displayed as INVALID and the chiller will not be
allowed to run while this is displayed.

Motor Voltage Rating
Displays the voltage rating of the MV VSD as re-
ceived from the MV VSD. This is the Motor Voltage
Rating value received from the MV VSD. Displayed
as 1300V, 3300V or 4160V. If an invalid value is re-
ceived, Invalid is displayed and the chiller will not be
allowed to run.
Output Frequency Rating
This is the rated output frequency value received from
the MV VSD. This value is the maximum drive fre-
quency (Hz) when the MV VSD receives a 100%
speed command from the OptiView Control Center. If
the value received is not 50Hz or 60Hz, INVALID is
displayed. If this is the case, then the Motor Voltage
Rating (above) determines the maximum frequency as
follows:
