Trouble Shooting

The following list contains a list of errors that might occur. For each error, a symptom
description is given. In the third column you will find a description how to locate and
possibly correct the error.
If you should not be able to correct an error occurred, please use the table how to
locate the source of the error as exactly as possible (nature of malfunction, at which
point in time did the error occur, etc.) before consulting us.

Use the process described in chapter 4 „Installation / Commissioning“ on page 12 to
protocol passages of the antenna throughout the site!

Error

Possible Cause(s)

Diagnosis / Correction

No system function

Even though a transpon

der is located within
reception range, there is
no serial output

Power supply is not sufficient.

Measure the voltage

No contact is possible;
only unintelligible charac

1.

1.CAN+ exchanged with CAN- by
mistake.

2.

Incorrect setting of transfer
parameters.

3.

Incorrect transfer procedure
selected.

1.

Check the corresponding con

nections.

2.

Select only 9600 or 19200 Baud,
8 Bit, even parity.

3.

Select the correct procedure, etc.
with the PC and the system
monitor program.

Output values are not
reproducible; lack of accu

racy.

Interferences

Check the value S in monitor mode.
If it is over approx. 50, there could be
interferences in the range 62 kHz.

No positioning pulse.

1.

Transponder defective.

2.

Loose cable connections.

3.

Interferences

4.

Antenna defective.

Check the transponder (e. g. with the
hand-held reader).

Permanent Positioning
Pulses.
