Troubleshooting Guide
Suggestion
Check if you are referring to the 17-pin connector or to the CBX
spring clamp connectors.
Is the sensor connected to Input 1 or Input 2?
Is power supplied to the photo sensor?
For NPN configuration, is power supplied to one of the two I1 or
I2 signals (A or B)?
For PNP configuration, is one of the two I1 or I2 signals
grounded (A or B)?
Are the photo sensor LEDS (if any) working correctly?
Is the sensor/reflector system aligned (if present)?
On the Reading Phase step check the Input 1 or Input 2 Deboun-
cing Time parameter setting.
On the Reading Phase step check the settings for Acquisition
Trigger, Reading Phase-ON, and Reading Phase-OFF parame-
ters.
On the Reading Phase step check the settings for Acquisition
Trigger, Reading Phase-ON, and Reading Phase-OFF parame-
ters.
Are the COM port parameters (Baud Rate, Parity, Data Bits, Stop
Bits) correctly assigned?
On the Reading Phase step check the settings of Acquisition
Trigger String, Reading Phase-ON String, and Reading Phase-
OFF String parameters.
Is the serial trigger source correctly connected?
Is the Phase frequency lower than the maximum frame rate?
Verify the correct software configuration settings.
Check the Code Collection parameters on the Reading Phase
step and the Data Formatting parameters on the Data Format-
ting step.
verify the Focus procedure
verify the Calibrate Image Density procedure.
