SECTION 2 - OPTIVIEW CONTROL CENTER INTRODUCTION
Input Power
Displays the total kilowatts measured by the MVVSD.
Value is provided by the MVVSD.
KW Hours
Displays the cumulative amount of kilowatts used over
time as the VSD motor operates. Value is calculated
by the OptiView Control Center from the Input Power
value provided from the MVVSD.
Pre-Rotation Vanes Position
Displays the Pre-Rotation Vane position as a value be-
tween 0 and 100%.
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
MVVSD Model
Displays the model number as received from the MV-
VSD. The model number is displayed as a number
representing the horsepower rating (ie; 1500HP). It
is derived from the Motor Rated Voltage and the Pro-
grammed Drive Current values received from the MV-
VSD according to the following table. If this results
in a model that is not defined in the lookup table, the
model number 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 MVVSD as received
from the MVVSD. This is the Motor Voltage Rating
as received from the MVVSD. Displayed as 1300V,
3300V or 4160V. If an invalid value is received,
"Invalid" is displayed and the chiller will not be al-
lowed to run.
Output Frequency Rating
This is the rated output frequency as received from the
MVVSD. This value is the maximum drive frequency
(Hz) when the MVVSD receives a 100% speed com-
mand from the OptiView Control Center. If the value
received is not 50 Hz or 60 Hz, INVALID is displayed.
If this is the case, then the Motor Voltage Rating (above)
determines the maximum frequency as follows:
Motor Voltage Rating Output Frequency Rating
2300 or 4160 V 60 Hz
3300 V 50 Hz
