10 Troubleshooting
10.1 Overview of Potential Errors and Faults
WARNING
Risk of injury due to damage to the device!
For reasons of safety, if a device shows visible signs of damage do not put it into
operation, or take it out of operation immediately.
Possible damage (depending on type):
•
Housing: cracking, splitting or fracture
•
Electrical connections (male connector or female connector): cracks or detach‐
ment from the housing
Table 21: Errors and faults
Situation Error/ fault
Mounting
■
Device poorly aligned to the objects with transponders (e.g.
faults due to metal surfaces located next to the device)
■
Damping materials between the device and transponders, e.g.
liquids
■
Trigger sensor for read cycle generation positioned incorrectly.
Possible cause: e.g., internal reading gate in the device is
opened too late or closed too early.
Electrical installation
■
Supply voltage too low or incorrect polarity
■
Data interfaces of the device wired incorrectly
■
Digital inputs or digital outputs incorrectly wired
Configuration
■
Functions not adapted to local conditions, e.g., parameters for
the data interface not set correctly
■
Device limits not observed, e.g. working range of the antenna
Operation
■
Ambient temperature too low or high
■
Read pulse control not suitably configured for the object(s) in
the working range.
■
Device faults (hardware/ software)
10.2 Detailed fault analysis
10.2.1 LEDs on the device
The status displays of the device can indicate possible faults or errors, see "Optical
status indicators on the display panel", page 73.
10.2.2 System information
The device reports any errors that occur in a number of ways. The error output is hier‐
archical. This hierarchical structure allows for an increasingly detailed level of analysis:
•
Communication errors can occur when transmitting telegrams (e.g. commands) to
a data interface of the device. The device then returns a fault code on the same
data interface.
•
For errors that occur during reading, the device writes errors codes in the status
log (see "Status log", page 81).
