Once the above tests have passed you can now add the “X tests” (MAGX VOCX WATX and STRX) into a
test program.
These are programmed in the same way as the “on board” Class- D tests (VOC MAGI WATT STRW) but will
allow you to use the higher excitation voltages.
These can be used in conjunction with the other standard AT test options, and in any order.
Points to note
1, Order of tests
For speed of execution, it is better to keep the AC INTERFACE tests together in one block where possible,
especially if they all share the same V and F settings.
See AT dot net Editor user manual 98-125 Section 4 for suggestions for test ordering to optimize speed.
2, Integration with HIPOT tests
See next section 3.6+3.7 for best practice when using the AC IF with HIPOT tests.
3, Max X TEST voltage.
Please remember that the maximum allowed requested voltages are defined by the Amp or Transformer
gain you have set in the external source set up.
For example
Using a 2:1 Step up transformer
AT output = 270 V
Max “X test” voltage programmable is 270 * 2 = 540 V
Using a power amp with gain of 25
ACIF ESD drive max output = 5 V
Max “X test” voltage programmable is 5 * 25 = 125
If you attempt to request more Volts that your configuration will allow, you will see the following prompt on
save.
