10.1

Troubleshooting

This chapter helps you to localize faults after they have been indicated (by 
LEDs or signal contacts). 

Fault indicated on the system LED

For more details see chapter 

“Display elements” on page 20

. 

Fault indicated on CH1, CH2

Make sure that the DIP switch S0 is in Position 1 if the OZD Profi 
connected to the electrical star segment of a star topology. 

See “Star topology” on page 28.

Make sure that the fault is still displayed after removal of the RS 485 
connector. 
Still displayed: Device is defective

c

. Replace the OZD Profi. 

No longer displayed: The fault lies in the RS485 bus segment.

Check all RS 485 connectors as described in “Connecting the 
electric bus cables”. 

See “Connecting the electric bus cables” on page 47.

Check the structure and shielding of the RS 485 bus segment.

Check the RS 485 bus segment using a PROFIBUS bus monitor. 

Check the configuration of all bus subscribers. 

Fault indicated on CH3, CH4

Make sure that optically only repeaters of the same type are 
connected together. 

See “Network Topologies” on page 24.

Make sure that the optical ports, which are connected via optical 
fibers, have been set to the same operating mode. 

See “Setting the operating mode and transmitting power” on page 43.

Make sure that the settings given in chapter ”Connecting the optic bus 
cables“ have been observed when connecting and laying the optical 
bus lines. 

See “Connecting the optic bus cables” on page 46.

c. This is not the case if the monomaster of a PROFIBUS network is connected to the RS 485 

bus segment which is to be examined. Replace the OZD Profi concerned with another OZD 

Profi from the network, and then carry out the test described above.

If the OZD Profi still malfunctions when connected elsewhere, the device is defective. 

Replace the OZD Profi.

If the OZD Profi does not malfunction elsewhere, the fault lies in the RS 485 bus segment. 

Carry out the measures described above.
