6 Troubleshooting
6.1 Fault Finding Using Camera LEDs
6.1.1 Yellow LED
The A101f regularly performs self tests. Detected errors are signaled by blinking of the yellow LED
on the back of the camera. The number of pulses indicate the detected error. If several error states
are present, the yellow LED outputs the error codes in succession.
See Table 6-1 for the description of the pulses.
6.1.2 Green LED
The green LED on the back of the camera is used to indicate whether power is being supplied to
the camera. When the green LED is out, it means that no power is present. When the green LED
is lit, it means that power is present.
LED Camera Condition
On Continuous The camera is OK.
3 pulses
ExTrig has not changed state for 5 seconds or longer. If you are not using an ExTrig
signal, this indication is normal and should be ignored.
6 pulses
The default camera configuration settings could not be loaded. Please contact Basler
technical support.
8 pulses
The FPGA could not be configured. Please contact Basler technical support.

*
Keep in mind that the circuit used to light the green LED does not perform a range
check. If power to the camera is present but it is out of range, the LED may be lit but
the camera will not operate properly.
