10 TROUBLESHOOTING 10.1 GENERAL GUIDELINES
 When wiring the device, pay careful attention to the signal name (acronym) on the 
CBX100/500 spring clamp connectors (chp. 4). If you are connecting directly to the 
Matrix 400™ M16 19-pin connector pay attention to the pin number of the signals (chp. 5). 
 If you need information about a certain reader parameter you can refer to the VisiSet 
program help files. Either connect the device and select the parameter you’re interested in 
by pressing the F1 key, or select Help>Paramters Help from the command menu. 
 If you’re unable to fix the problem and you’re going to contact your local Datalogic office or 
Datalogic Partner or ARC, we suggest providing (if possible): Application Program version, 
Parameter Configuration file, Serial Number and Order Number of your reader. You can 
get this information while VisiSet™ is connected to the reader: the Application Program 
version is shown in the Terminal Window; the Parameter Configuration can be saved to an 
.ini file applying the File>Save Configuration File command in the Parameter Setup 
window; Serial Number and Order Number can be obtained by applying the respective 
command in the Tools menu. 
TROUBLESHOOTING GUIDE 
Problem Suggestion 
Power ON: 
the “POWER” LED is not lit. 
 Is power connected? 
 If using a power adapter (like PG6000), is it connected 
to wall outlet? 
 If using rail power, does rail have power? 
 If using CBX, does it have power (check switch and 
LED)? 
 Check if you are referring to the M16 19-pin connector 
or to the CBX spring clamp connectors. 
 Measure Voltage either at pin A and pin L (for 19-pin 
connector) or at spring clamp Vdc and GND (for CBX). 
One Shot or Phase Mode 
using the Input 1 (External 
Trigger) or Input 2: 
the ”TRIGGER” LED is not 
blinking while the External 
Trigger is switching. 
 Check if you are referring to the 19-pin connector or to 
the CBX spring clamp connectors. 
 Is the sensor connected to the 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)? 
 In the Digital I/O folder check the EXTERNAL 
TRIGGER or INPUT 2\Debounce Filter parameter 
setting. 
 In the Operating Mode folder check the settings for 
Reading Phase-ON, Acquisition Trigger and 
Reading Phase-OFF parameters.
