Troubleshooting

If the NI PXI-4110 is operating incorrectly, perform the following actions:

• Verify that the hardware and software are properly installed.
• Verify that all connections, including the front panel connections to the output channels and auxiliary power supply (if applicable), are secure.
• Verify that the output channels are enabled. If necessary, use the niDCPower Configure Output Enabled VI or the niDCPower_ConfigureOutputEnabled function to enable the output channels.
• Inspect all fuses, and verify that each is in working condition. If necessary, replace any blown fuses.

  Tips  Although blown output channel and auxiliary power input fuses are not software detectable, you can use the niDCPower Auxiliary Power Source Available property or the NIDCPOWER_ATTR_AUXILIARY_POWER_SOURCE_AVAILABLE attribute to troubleshoot the auxiliary power input fuse. If you suspect a blown output channel fuse, keep in mind that an output channel with a blown fuse can source only a few milliamperes of current regardless of the programmed current limit.

• Run a self-test on the NI PXI-4110 using the niDCPower Self Test VI or the niDCPower_self_test function. If the NI PXI-4110 is damaged, contact NI for information about repair.
