Fault source
Possible cause
Remedy
The operating voltage
LED (PWR/ERR) does
not light up.
Power supply is
interrupted.
Ensure that the power supply is
connected to a 24 V DC source.
The CH1 or CH2
indicator does not light
up even though the R/W
head is connected to
port 1 or port 2.
The cable is defective or
not connected correctly.
Check the cable and repair if
necessary.
The R/W head is
defective.
Check the R/W head and replace
if necessary.
A read command (e.g.
SR
...) gives the status 4
even though the syntax
is correct.
An incorrect tag type is
selected for the relevant
channel (e.g. IPC02).
The read commands
only function with data
carriers and not with
code carriers.
Preset the correct tag type (e.g.
IPC03) or "Autodetect" using the
CT
... command.
The LEDs in the reading
head and the CHx
indicator on the
IDENTControl are
flashing.
The connected reading
head does not support
the preset tag type.
Select a tag type that the reading
head supports.
The
SG
or
EG
command (Get
configuration) gives the
status 4 even though
the syntax is correct.
IPC03 is not selected
for the relevant channel.
The configuration
commands only
function if the data
carrier IPC03 is
selected and not in
Autodetect mode.
Preset the tag type IPC03 using
the
CT
... command.
The red "BusError" LED
lights up (slave is not in
"DataExchange" state).
There is no longer a
connection to the
master.
Check the cable, the connection,
and the terminator and repair if
necessary.
The slave address is
incorrect.
Configure the device and the
master with the same slave
address (on the slave in the
hexadecimal display).
