Troubleshooting
•
The sensor power supply is of appropriate voltage for interfacing to NI Smart Camera
isolated inputs. Refer to the
, for
information about isolated inputs. Refer to Appendix A,
specifications.
•
You configured the device in MAX or Vision Builder AI to expect a trigger. Refer to the
section of Chapter 5,
, for information about
configuring an external trigger.
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
section of Chapter 6,
, 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,
. 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.
