SECTION 2 - OPTIVIEW CONTROL CENTER INTRODUCTION
VSD Fault (LED)
Indicates the VSD is reporting a fault.
Input % Full Load Amps
Displays the input current as a percentage of the job
Full Load Amps (FLA) value, based on the highest
phase.
Input Current Limit Setpoint
Displays the input current limit value in use. This value
could come from a 0-20mA, 4-20 mA, 0-10VDC or
2-10VDC input in Analog Remote mode, PWM signal
in Digital Remote mode, E-Link Gateway interface in
BAS (ISN) mode, or a locally programmed value.
Pulldown Demand Time Left
Displays the time remaining in the programmed
pulldown period if the value is nonzero.
VSD Output Voltage
Displays the output voltage measured to the motor.
VSD Output Frequency
Displays the present output frequency to the motor.
Max Chiller Frequency
Displays the maximum value that the Output
frequency is limited to for the chiller, based on
configuration.
Input Power
Displays the total input Kilowatts measured by the
VSD.
Input kW Hours
Displays the cumulative amount of kilowatts used over
time as the VSD motor controller operates.
Output Current (RMS) - Phase A, B, C
Displays the RMS current measured to the motor, per
phase.
PRV Position - Gas Path "A" Only
Displays the pre-rotation vane position as a value be-
tween 0 and 100%.
VGD Position - Gas Path "B" Only
Displays the variable geometry diffuser position as a
value between 0 and 100%.

Input kVA
Displays the supply kva measured by the VSD.
Input Power Factor
Displays the relationship between the Input Power and
the Supply kVA.
Rated Motor Voltage
Displays the motor voltage rating, based on configura-
tion.
Maximum Motor Current
Displays the maximum motor current, based on con-
figuration.
Motor % Full Load Amps
Displays the percentage of maximum motor current
presently delivered, based on highest phase.
Voltage Total Harmonic Distortion - (L1, L2, L3)
Displays the Total Harmonic Distortion (THD) for
each of the voltage lines as calculated by the VSD.
Input Current Total Demand Distortion -
(L1, L2, L3)
Displays the Total Dynamic Distortion (TDD) for each
of the supply current lines as calculated by the VSD.
PROGRAMMABLE
Local Input Current Limit
Access Level Required: OPERATOR
Allows the user to specify the maximum allowed input
current (as a percentage of job FLA). When the input
current reaches this value, the input current override
takes effect. When the unit is operated via BAS (ISN)
control mode the ISN current limits will override the
pulldown demand limit and current limit set points. It
is assumed that the BAS algorithms will reset current
limits as required.
Pulldown Demand Limit
Access Level Required: OPERATOR
Allows the user to specify the current limit value (as a
percentage of FLA) to which the chiller will be limited
during the specified pulldown limit time. This value
will override the input Current Limit value during this
time period. This function is used to provide energy
savings following chiller start-up. When the unit is
