Harmonic filter details screen
Figure 56: Harmonic filter details screen (Style D VSD and VSD with part number 371-03789-
XXX [503HP 60 Hz; 419HP 50 Hz])
This screen displays more detailed information pertaining to the IEEE-519 Harmonic Filter.
Table 95: Display only fields
Field/LED name Description
Motor Run (LED)
Indicates whether the digital output from the controls is commanding the motor to
RUN.
Motor Current % Full Load Amps
Displays the motor current as a percentage of the Full Load Amps (FLA) value. For the
Variable Speed Drive this is the data returned by the VSD Logic Board.
Current Limit Setpoint
Displays the current limit value in use. This value could come from a 0 mA to 20 mA,
4 mA to 20mA, 0 VDC to 10 VDC, or 2 VDC to 10 VDC 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
nonzero.
Operating Mode (Run/ Stop) Indicates whether the Harmonic Filter is operating.
VSD Model
Displays the horsepower for which the attached Harmonic Filter is configured. Access
Level Required: Service
DC Bus Voltage Displays the DC Bus voltage as measured by the Harmonic Filter.
Supply Contactor (LED) Indicates whether the output to the Supply Contactor is energized.
Precharge Contactor (LED) Indicates if the output to the Precharge Contactor is energized.
Phase Rotation Displays the phase rotation detected by the Harmonic Filter (A, B, C or C, B, A)
Total Supply kVA Displays total supply Kilovolt-Amps measured by the Harmonic Filter.
Heatsink Temperature
(Labeled Baseplate Temperatures on VSD with part number 371-03789-xxx (503HP 60
Hz; 419HP 50 Hz). Displays the temperature of the Harmonic Heatsink (baseplate).
Voltage Peak (N-L1, N-L2, N-L3)
Displays the 3-phase peak voltages as measured by the Harmonic Filter (Neutral to
Line).
RMS Voltage (L1-L2, L2-L3, L3-L1) Displays the 3-phase RMS Voltages across each line.
