13.4 Test Options
Nominal Voltage Mode
The IEC 61000-4-29 test standard allows testing at a single nominal Vdc value if the voltage
range of the EUT is less than 20 % of the low range value. Thus, if an EUT has a nominal input
range from 100 to 110 Vdc, the range is 10 V which is only 10 % of the low range value (10/100 =
10 %). In this case, either the upper or lower limit value or a value in between may be used to test
the EUT. If the range exceeds 20 %, the test has to be performed at both upper and lower range
settings. The CIGui32 or CIGuiSII will allow the operator to select single value testing but will
prompt a warning if the values entered represent a greater than 20 % range.
Pre-Test Delay
For both Dips/Interruptions and Variations runs, it is possible to specify a pre-test delay. This is a
period expressed in seconds during which the Vdc nominal value will be applied to the EUT
before the actual test sequence starts.
13.5 Test Execution
The selected test mode can be started by pulling down the Run menu and selecting All or by
clicking on the Start button. During test execution, no changes to test parameters are allowed.
The test progress can be monitored at the bottom of the window in the status bar. The progress
through each sequence can be monitored as well as each test step currently executing is
highlighted.
13.6 Test Results
There is no way for the CIGui32 or CIGuiSII to determine the outcome of this test as a clear
definition of a failure can not be given. The draft standard called out the following possible test
results:
“The�test�results�shall�be�classified�on�the�basis�of�the�operating�conditions�and�
functional specifications of the equipment under test, as in the following, unless
different specifications are given by product committees or product specifications.
a) Normal performance within the specification limits
b) Temporary degradation or loss of function or performance which is self-
recoverable.
c) Temporary degradation or loss of function or performance which requires operator
intervention or system reset.
d) Degradation or loss of function which is not recoverable due to damage of
equipment (components) or software, or loss of data.
