User's Manual

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 SensorSMART platform including peripheral units and their cables, also potential object
recognition switches.
 The environment including large objects between antenna and sensor, 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, not overlook the problem sources and “Fault finding procedures on
system level” should 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.
LF: Green when LF message is sent.
COM: UHF communication – if broadcast is sent,
LED goes green; if a packet is received as a
valid answer, LED goes orange.
RUN: Green when device is powered.
