Troubleshooting 

5.1

 

General  

This chapter covers how faults can be recognized and rectified.  There are potentially four main 
problem sources: 
 

 

The  user  control  system,  including  task  requirements,  communication  cables,  peripheral  units 
with possible object recognition switches. 

 

The  ILR  system  including  peripheral  units  and  their  cables,  also  potential  object  recognition 
switches. 

 

The environment including large objects between antenna and tag, electrical disturbance sources, 
human intervention, etc. 

 

The  quality  of  the  technical  design,  including  alignment  between  antenna,  ratio  of  task 
requirements/available  communication  time  etc.  The  information  about  system  performance  is 
contained in the relevant datasheets. 

 
When planning the total system do not forget these problem sources and “Fault finding procedures on 
system level” should possibly be included in the host system.  How this could look in detail depends on 
the relevant system concept and very likely varies from one system to another. 
 

5.2

 

Status Display (LEDs) 

LOOP 

This LED lights green during sending a LF telegram (about 20 ms). In the case of a 
loop error (loop broken or the set point of the loop current couldn’t be reached) the 
LED lights red when sending a LF telegram. 

RUN 

This LED blinks green, indicating the system is running normal. 

BUS 

Lights green during receive and orange during response – also for Bluetooth. 

ERR 

Blinking: system error on start-up, firmware execution failed. 

 

5.3

 

Loop Error 

There are three types of possible errors. Every of the following errors will switch the LOOP LED to red. 
Also the marker will try to continue sending. 
 
Loop broken 

Loop current is too low or near zero 

Loop current out of range  When setting the loop current (power) the marker tries to control the 

output signal in a way, that the preset current is measured during LF 
transmission. This adjustment is only done once, if the loop current is 
changed by the user. During normal operation the loop current is 
observed every telegram. If then the loop current is ±20 % out of range 
the error condition will set. 

Loop shorten
