The three phases of RMS filter current are measured by the output DCCTs'. This
information is sent to the harmonic filter logic board. If any one phase of filter cur-
rent exceeds a threshold for 40 seconds a shutdown will occur. Refer to the chart
below for the shutdown threshold value.

The DC link is filtered by many large capacitors. These capacitors are connected
in series to achieve a higher DC link voltage then can be supported by a signal
capacitor. It is important that the voltage is shared equally between the two sets of
series capacitors. Each set of capacitors must share approximately 1/2 of the total
DC link voltage. The harmonic filter logic board then measures the voltage of the 2
sets of the bus capacitors. If at anytime while the harmonic filter is running that the
difference in the voltage between the 2 sets of capacitors is greater than 50 VDC
(for 380 through 460 VAC input voltage) 65 VDC (for 575 VAC input voltage), then
a shutdown will occur.
During initialization, with no current flowing through the Direct Current Current
Transducers (DCCT's), the DCCT's output voltages are measured and compared
with a preset limit in the harmonic filter logic board. If the measured values exceed
the preset limits, the DCCT's are presumed to be bad and this shutdown will be
generated.
The harmonic filter logic board continuously monitors the harmonic filter DC link
voltage if the level of the DC link voltage exceeds a range of 822 to 900 VDC (for
380 through 460 VAC input voltage) or 999 to 1099 VDC (for 575 VAC input volt-
age) this shutdown is initiated. Keep in mind that the harmonic filter has its own
DC Link as part of the harmonic filter power unit. The harmonic filter DC Link is not
connected in any way with the drive's DC Link.
The output current of the harmonic filter is read by the Direct Current-Current
Transducer (DCCT). This current information is sent to the harmonic filter logic
board where it is compared against a threshold. If the output current of the har-
monic filter power unit is greater than the threshold, then the harmonic filter will turn
off for 5-6 line cycles. After that time the filter operation will resume. If the harmonic
filter operation is stopped 3 times within a period of 60 line cycles, then the filter
and VSD power units are shut down and this message is generated.

This shutdown states that the hardware on the harmonic filter logic board is indicat-
ing a fault, but the software on the harmonic filter logic board does not state why.
The harmonic filter logic board signals a fault condition to the OSCD logic board
but does not respond to a software request for fault information.
