Banner TCNM AD/EX Instruction Manual - 11 Troubleshooting
11 Troubleshooting
11.1 General Guidelines
When wiring the device, pay careful attention to the signal name (acronym) on the TCNM-ACBB1 spring clamp connectors.
If you are connecting directly to the scanner's 25-pin connector, pay attention to the pin number of the signals.
If you need information about a certain reader parameter, refer to the GeniusPlus program help files. Either connect the
device and select the parameter you are interested in by pressing the F1 key, or select Help > Parameters Help from the
command menu.
If you are unable to fix the problem and need to contact Banner Engineering Corp, provide (if possible) the Device
Configuration files (*.ddc). Connect through GeniusPlus and click the Save icon from the toolbar. Also note the device's
model, serial number, and order number.
11.2 Troubleshooting Guide
Problem
Solution
Power On: the “Power On”/”Ready”
LED is not lit
•
Is power connected?
•
If using rail power, does the rail have power?
•
If using TCNM-ACBB1, does it have power (check the switch and LED)?
•
Measure voltage either at pin 13 and pin 25 (for 25-pin connector) or at
spring clamp V dc and GND (for TCNM-ACBB1).
On Line Mode: TRIGGER LED is not
lit (when external trigger activates)
•
Is the sensor connected to I1A and I1B spring clamps (for TCNM-ACBB1)
or to pins 18 and 19 (for 25-pin connector)?
•
Is power supplied to the sensor?
•
Are the sensor LEDS working correctly?
•
Is the sensor/reflector system aligned?
On Line Mode: TRIGGER LED is
correctly lit but nothing happens (no
reading results)
•
Is the software configuration consistent with the application condition
(operating mode, etc.)?
•
In the GeniusPlus program select the Operating Mode branch and check
for related parameters.
Serial On Line Mode: the reader is
not triggered (no reading results)
•
In the GeniusPlus program select the Operating Mode branch and check if
Serial On Line is selected in the On Line Options.
•
Are the Start – Stop characters correctly assigned?
•
Is the serial trigger source correctly connected and configured?
On Line Mode and Serial On Line:
Reader doesn’t respond correctly to
the expected external signals end
In the GeniusPlus program select the Operating Mode branch and check the
Reading Phase Timeout parameter.
SMART-TEACH functions do not
work. LEDs light up but do not allow
access to the functions
The SMART-TEACH functions do not work if the scanner motor or laser are turned
off. Check if the motor or laser are turned off through the following parameters:
•
Beam Shutter = enabled
•
Scan Speed = Motor Off
•
Energy Saving > Serial Motor Off has been sent
Reading: Not possible to read the
target barcode (always returns No
Read) or the Auto Setup procedure
Fails
Check the synchronization of reading pulse with object to read: Is the scan line
correctly positioned?
Place the barcode in the center of the scan line and run Test mode (selectable by
GeniusPlus as an Operating Mode). If you still have trouble, check the following:
•
Is the reading distance within the allowed distance (see reading
diagrams)?
•
Is the Tilt angle too large?
•
Is the Skew angle less than 10° (direct reflection)?
•
Choose the Code Definition branch and enable different Code Symbologies
(except Pharmacode). Length = Min and Max (variable).
•
Is the barcode quality sufficient?
•
If you had no success, perform the test using the BARCODE TEST CHART
included with the product.
