Troubleshooting
This chapter describes how errors in the interrogator can be recognised and eliminated.
9.1
Overview of errors and malfunctions which could occur
9.1.1
Error during the installation
•
The interrogator has been unsuitably aligned to objects with transponders (e. g. a
shield)
•
Reading pulse sensor has been positioned incorrectly (e.g. internal reading gate is
opened too late or shut too early)
9.1.2
Error during the electrical installation
•
Interfaces of the interrogator were wired incorrectly
9.1.3
Error during configuration
•
Functions have not been adjusted to the local conditions, e.g. parameters for the data
interface are set incorrectly
•
Device-related limits have not been considered, e.g. reading distance
•
Trigger source for reading pulse selected incorrectly
9.1.4
Malfunctions during operation
•
Start/Stop operation: External reading pulse is missing, more than one object is in the
reading area
•
Device error (hardware/software)
9.2
Detailed malfunction analysis
9.2.1
LEDs on the interrogator
Among other things, the following statuses can be read from the LEDs on the interrogator's
housing (see
chapter 4.7.2 LEDs on the interrogator's housing, page 27
•
Ready
•
Status of the reading result (result)
•
Data traffic on the host, aux and CAN interface
The LEDs can display possible malfunctions or errors. Please refer to the system informati-
on for further details.
9.2.2
System information
The interrogator displays errors in various ways. The error output is hierarchised and always
allows a detailed analysis:
•
Communication errors can occur while transferring telegrams to the interrogator. In this
case, the interrogator returns an error code.
•
Error codes are written into a status protocol for errors which occur during a reading
(see subsequent chapter).
