MEDIUM VOLTAGE VARIABLE SPEED DRIVE SCREEN

FIGURE 33 - MEDIUM VOLTAGE VARIABLE SPEED DRIVE SCREEN

OVERVIEW
This screen displays information pertaining to a Medi-
um Voltage Variable Speed Drive (MV VSD). For de-
tails of MV VSD operation and setpoints, refer to Me-
dium Voltage Variable Speed Drive – Service (Form
160.00-M6).
DISPLAY ONLY
Motor Run (LED)
Indicates whether the digital output from the controls is
commanding the chiller to run.
Motor Current % Full Load Amps
Displays the motor current as a percentage of the Full
Load Amps (FLA).
Current Limit Setpoint
Displays the current limit value in use. This value could
come from a 0 to 20mA, 4 to 20mA, 0 to 10VDC or 2
to 10VDC input in Analog Remote mode, PWM signal
in Digital Remote mode, E-Link Gateway interface in
ISN mode or a locally programmed value.

Pulldown Demand Time Left
Displays the time remaining in the programmed
pulldown period if the value is not zero.
Output Voltage
Displays the output voltage to the motor. Value is pro-
vided by the MV VSD.
Output Frequency
Displays the present output frequency to the motor.
Value is provided by the MV VSD.
Input Power
Displays the total kilowatts measured by the MV VSD.
Value is provided by the MV VSD.
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 MV VSD.
