Description
Displays the total kilowatts measured by the MVVSD. Value is
provided by the MVVSD.
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.
Displays the Pre-Rotation Vane position as a value between 0 and
100%.
Illuminates when the VSD cooling fans are being commanded to
run.
Illuminates when the pre-charge relay is commanded to energize.
Displays the three phases of output current to the motor.
Displays the three phases of DC Bus voltage
Displays the model number as received from the MV­VSD. The model
number is displayed as a number representing the horsepower
rating (ie; 1500HP). It is derived from the Motor Rated Voltage
and the Programmed Drive Current values received from the MV-
VSD according to the following table Table 107. 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.
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 allowed to
run.
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 command 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:
