All minimum/maximum
values may be reset via reset
pushbutton on faceplate,
discrete input or
communications command.
Values are updated at least
once every 16 line cycles.
The F3 function key accesses
the Harmonic Analysis
screens. Two cycles of data
sampled at 128 samples/
cycle are simultaneously
recorded for:
●
Current
●
Phases A, B, C, N, G
●
Voltage
●
Phases A-B, B-C, C-A
●
Phases A-N, B-N, C-N
●
Neutral to Ground
Magnitudes (or % of
fundamental) of odd and
even multiples of the
fundamental from 2nd–50th
are displayed. The phase
angle associated with each
multiple of the fundamental
is also displayed.
Event/Alarm Analysis Screens
Example of Event Analysis Screens
Waveform Screen Available with
Model 6600
Pressing the F2 function key
accesses the Event Analysis
screens. These display the
following data for up to ten
event/alarm conditions:
●
Description, date and
time of event/alarm with 10
millisecond resolution
●
Current, voltages, power
readings, demand
readings, frequency and %
THD at time of event/alarm
●
Current and voltage
distortion information
available on Harmonic
Analysis screens
Event data is stored in non-
volatile memory. If a reset
threshold is programmed,
the duration of the event
(e.g., undervoltage) is also
displayed. With Eaton’s
communications option and
software, waveforms and
harmonic profiles may be
displayed on a PC.
Event Conditions
Events may be triggered by
up to seven of any of the
following conditions:
Voltage Disturbances
●
Undervoltage/sag—
any V
L- L
, V
L- N
(40–100%)
Note: 60% minimum for self-
powered unit.
●
