7.5.4 Troubleshooting 

Fault 

Possible cause 

Testing and rectification 

Sensor signal 
is not 

 

received. 

Sensor does not send. 

Send a test packet by briefly pressing the key 
on the sensor. LED must flash once. 
If necessary, test the battery state using PUII. 

 

Sensor lies outside the  
range of the I/O-Unit. 

Test the wireless link using the "wireless meas-
uring system". If the display value is smaller 
than "8", change the installation location. Alter-
natively, use a repeater or an external antenna. 

 

Sensor has been removed or 
interchanged. 

Replace the sensor or/and re-register. 

 

Incorrect or no sensor registered 
to the I/O-Unit. 

Check the sensor list on the Processing Unit 
web page. 
If necessary, re-register the sensor. 

 

Antenna not connected correctly. Check the antenna installation, plug connectors 

and the laying of the antenna cable. 

 

I/O-Unit is installed in a  
shielded area. 
 

Test the wireless link using the "wireless meas-
uring system". If the display value is smaller 
than "8", use an external antenna. 

 

Interfering transmitter (continu-
ous transmitter) present. 

Test the wireless link using the "wireless meas-
uring system". Display value should be 8-9 in 
the vicinity of the I/O-Unit. If necessary, rectify 
the interfering transmitter. 

Sensor is  
sometimes not 
received. 

Sensor lies in the fringe range  
of the I/O-Unit. 

Test the wireless link using the "wireless meas-
uring system". If the display value is smaller 
than "8", change the installation location or use 
a repeater. 

 

Sensor lies in the fringe range  
of the I/O-Unit. 

Increase the power reserves of the wireless link: 
Mount the base and the sensor as high as pos-
sible to minimise the absorbing characteristics 
of the floor, and the effect of objects and per-
sons. 

 

Intermittent change of the  
ambient conditions (enclosure, 
door, objects, persons, interfer-
ing transmitter, etc.). 

Increase the power reserves of the wireless link: 
Change the installation location of the sensor or 
the I/O-Unit (the other sensors of the I/O-Unit 
then must be recalibrated) or use repeaters. If 
necessary, rectify the interfering transmitter. 

 

The installation location of the 
sensor changes periodically  
(mobile sensor). 

Change the installation location of the sensor so 
that it lies in the receiving area. 

 

Interfering transmitter  
sometimes present. 

Rectify or switch off the interfering transmitter.
