Resetting the AC Mains Circuit Breaker
© National Instruments Corporation
If your PXI-1000 encounters an over-current condition, the circuit breaker
located on the rear panel will trip to prevent damage to the mainframe.
Complete the following steps to reset the circuit breaker:
1.
Turn the front panel (remote) power switch to the Standby position.
2.
Turn off the rear main power switch.
3.
Depress the circuit breaker to reset it.
4.
Turn on the rear main power switch.
5.
Turn the front panel (remote) power switch to the On position.
If the circuit breaker trips again, complete the following steps:
1.
Turn the front panel power switch to the Standby position.
2.
Turn off the rear main power switch.
3.
Disconnect the mainframe from the AC mains power source.
4.
Remove all modules from the mainframe.
5.
Complete the test procedure described in the
Power and Testing Power up
Configuration.
6.
If any voltages are outside the acceptable limits, contact National
Instruments.
7.
If all voltages are within the acceptable limits, verify that your
PXI-1000 can meet the power requirements of your CompactPCI or
PXI modules. Overloading the chassis can cause the breaker to trip.
Refer to Appendix A, Specifications.
8.
The over-current condition that caused the circuit breaker to trip may
be due to a faulty CompactPCI or PXI module. Refer to the
documentation that was supplied with the modules for troubleshooting
your modules.
