?
A bus fault is indicated on the automation sys-
tem.
!
The PROFIBUS DP data traffic has suffered a fault.
!
Bus cable interrupted.
•
Check bus cable.
!
Bus cable connections confused in the plug.
•
Check the wiring.
!
A and B cables confused.
•
Check cables.
!
Terminal resistors connected incorrectly.
•
Switch on the terminal resistors on the first and last
station in the segment and switch them off for all other
stations.
!
Incorrect PROFIBUS address set.
•
Correct the address setting – switch the unit off and
then on again to save the address.
!
Bus cables too long.
•
Reduce cable length or baud rate – see page 5
▷
If the transfer rate is reduced, remember that this
will increase the signal running times to and from the
individual units.
!
Poor shielding.
•
The shield must be connected to the shield clips in
the PROFIBUS DP plugs in full and over a wide area.
!
Poor equipotential bond.
•
The PROFIBUS DP shield should be connected at all
points to the same ground potential by grounding the
BGT. If necessary an equipotential bond cable must
be laid.
!
If faults only occur sporadically in the PROFIBUS DP
system, and are mostly only indicated briefly in the
bus master, the terminal resistors, shielding, cable
lengths/routes, equipotential bond and the use of
interference-suppressed ignition electrode plugs (1 kΩ)
in particular should be checked.

Further notes on building PROFIBUS DP networks
are set out in the instructions for the automation
system or, for example, in the “Installation Guideline
for PROFIBUS DP/FMS”, available from the PUO
(PROFIBUS User Organization).

All the burners are constantly in operation, re-
gardless of data traffic.

Designed lifetime
This information on the designed lifetime is based on using
the product in accordance with these operating instruc-
tions. Once the designed lifetime has been reached, safety-
relevant products must be replaced.
Designed lifetime (based on date of manufacture) in ac-
cordance with EN 230 and EN 298 for PFA/BGT: 10 years.
You can find further explanations in the applicable rules and
regulations and on the afecor website (www.afecor.org).
This procedure applies to heating systems. For thermopro-
cessing equipment, observe local regulations.
Logistics
Transport
Protect the unit from external forces (blows, shocks, vibra-
tion). On receipt of the product, check that the delivery is
complete, see page 2 (Part designations). Report any
transport damage immediately.
Storage
Store the product in a dry and clean place.
Storage temperature: see page 7 (Technical data).
Storage time: 6 months in the original packaging before
using for the first time. If stored for longer than this, the
overall service life will be reduced by the corresponding
amount of extra storage time.
Packaging
The packaging material is to be disposed of in accordance
with local regulations.
Disposal
Components are to be disposed of separately in accord-
ance with local regulations.
