13.1 Test Setup
The following parameters and controls are available for executing the EN 61000-4-29 test:
Parameter / Control Description
Nominal DC voltage
Opening this window will set the upper voltage range parameter to the
present steady state voltage setting of the DC supply. If required, a new
value can be entered for use during the test. At the end of the test, the DC
Supply will remain at this voltage level. The upper voltage range value
entered cannot exceed the selected voltage range. Note that DC voltage
variations to levels above 100 % of Unom may require selection of the
high voltage range.
The lower voltage range must be set to the lowest EUT rated Vdc. If the
EUT voltage range is less than 20 % of its low range value, a single Vdc
level may be used.
Sequence Available sequences for selection are:
Voltage Dips and Interruptions
Voltage Variations.
Either one or both sequences can be selected for execution.
Output Select
The output selection is shown to the left. If a 3 phase AC/DC power
source model is used, this field allows selection of output channel A, B, C
or all three channels (outputs). The same test sequence is applied to all
selected outputs. For single phase power systems, this field defaults to
channel A.
Start
Starts the EN 61000-4-29 test using the parameters set by the user. Test
progress is shown at the bottom of the window.
Abort Aborts test in progress.
The required EN 61000-4-29 test parameters must be entered in the test data entry grid before running a
test. Previously stored test files can be loaded from the File, Open menu. Test files use a .429 file
extension and only files with this extension can be loaded.
The MXGUI is distributed with pre-defined test parameter files for the generic EN 61000-4-29 test
sequences. Additional test parameter files e.g. for specific product categories, can be created by the user
by editing the data entry grid and saving the new data under a user-specified name. The following
parameters and controls are available for executing the EN 61000-4-29 test:

The lower voltage range must be set to the lowest EUT rated Vdc. If the
EUT voltage range is less than 20 % of its low range value, a single Vdc
level may be used. If the user selects only one of the two DC levels and
the delta between them exceeds 20 % of the low DC range, a warning
message will appear notifying the user of this condition. As a rule, both
voltage must be selected for testing when this prompt appears.
Sequence Select
Available sequences for selection are:
