6 Troubleshooting
6.1 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, intervention by persons, etc.
• The quality of the technical design, including alignment between antenna, data, 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.
