You can use LabVIEW or the NI-DCPower soft front panel to test the PXIe-4135 safety interlock. Refer to the
Testing the Safety Interlock section of the PXIe-4135 Getting Started Guide for more information
about testing the safety interlock.
To ensure safe operation of the PXIe-4135, periodically test the safety interlock for
proper functionality. The recommended test interval is at least once per day of
Ensure the PXIe-4135 is disconnected from the NI-4134 before testing the safety interlock. The
safety interlock test generates voltages up to 200 V, which could damage the NI-4134 if connected.
