LED Error Indications
STATUS LED Error Conditions
The NI Smart Camera indicates specific error conditions by flashing the
STATUS LED a specific number of times. Refer to the STATUS LED
section of Chapter 6, LEDs and DIP Switches, for the STATUS LED
flashing sequences and the corresponding error condition.
POWER LED is Not Lit When the NI Smart Camera is Powered On
If the power supply is properly connected to the smart camera, but the
POWER LED does not light up, check that the power supply is 24 V
+20%/–15% and within the specifications outlined in Appendix A,
Specifications. Verify that the power supply can supply enough current for
the smart camera model in use. Using a power supply that is not within
these specifications might result in an unresponsive or unstable system and
could damage the smart camera.
Caution The 24 V external lighting strobe is an unregulated output dependent on the range
of the power supply provided to the smart camera. If the power provided to the smart
camera is +20%/–15% with +5% AC ripple, the output could be as high as 30 V. If the
provided power exceeds the input voltage specifications of the third-party lighting
controller, do not connect the 24 V lighting strobe output to the controller to prevent
damage to the controller. Use a power supply with tolerances that meet the requirements
of the controller, or use the 5 V external lighting strobe.
