DISPLAY ONLY FIELDS
Indicates whether the digital output from the controls is commanding the motor
to RUN.
Indicates the VSD is reporting a fault through the hardwired digital input.
Displays the input current as a percentage of the job Full Load Amps (FLA)
value, based on the highest phase.
Displays the input current limit value in use. This value can come from a
4-20mA, 0-10VDC or PWM signal in a Hardwired Remote mode, an SC-Equip or
interface in BAS mode, or a locally programmed value.
Displays the time remaining in the programmed pulldown period if the value is
nonzero.
Displays the output voltage measured to the motor.
Displays the present output frequency to the motor.
Displays the maximum value that the Output frequency is limited to for the
chiller, based on configuration.
Displays the total input Kilowatts measured by the VSD.
Displays the cumulative amount of kilowatts used over time as the VSD motor
controller operates.
Displays the RMS current measured to the motor, per phase.
Displays the variable geometry diffuser position as a value between 0 and 100%.
