PFA 700
Fieldbus interface for interworking of up to nine au-
tomatic burner control units PFU 760 or PFU 780 to
industrial communication networks using PROFIBUS
DP. The PFA 700 can be plugged into the pre-wired
module subrack BGT SA-9U/1DP, together with the
automatic burner control units.
PFA 70
Fieldbus interface for interworking of up to eight au-
tomatic burner control units PFU 780 to industrial
communication networks using PROFIBUS DP. The
PFA 710 can be plugged into the pre-wired module
subrack BGT SA-8U/1DP, together with the auto-
matic burner control units.
PFA 700, PFA 70

Installing the BGT
CAUTION
Please observe the following to ensure that the
PFA and the automatic burner control units PFU
are not damaged during operation:
– It must be ensured that the module subrack is
well ventilated in order to avoid overheating.
– In the case of several module subracks mounted
on top of one another, we recommend remov-
ing the perforated plates Afrom between the
module subracks, and inserting a rack-mounted
fan Bunderneath the module subracks.

DANGER
Electric shocks can be fatal! Module subracks must
be integrated in the equipotential bonding system.
▷Installation position: any.
▷
Distance between PFU and burner: max. 100m
(328 ft).
Wiring the BGT
 Disconnect the system from the electrical power
supply.
▷
Use a resistor with low impedance at high fre-
quencies for grounding the BGT.
▷Ensure an equipotential bond between the vari-
ous slaves.
▷Switch on the terminal resistor on the first (PLC)
and last (BGT/PFA) station on the Profibus plug–
see page 12 (Profibus plug for PFA).
▷ There are four digital inputs (X10.1 to X10.4) and
four digital outputs (X10.6 to X10.9) available.
▷Load per input: 24 V DC, ± 10%, <10mA.
▷Load per output: relay contact, max. 1 A, 24 V
(not fused internally).
BGT SA-9U/DP
 Wire as shown on the circuit diagram, see page
8 (BGT SA-9U/1DP connection diagram).
BGT SA-8U/DP
 Wire as shown on the circuit diagram, see page
10 (BGT SA-8U/1DP connection diagram).
Setting the PFA
▷All the unit-specific parameters for the PFA are
saved in a device master data file (GSD file, see
www.docutheck.com).
 Copy device master data for the PFA into the
programmable logic controller (PLC).
▷ The steps required to copy the file are described
in the instructions for the PLC.
 Configure the PROFIBUS DP using the appropri-
ate tools for the PLC you are using.
▷The PFA will automatically identify the baud rate
(max. 1.5 Mbit/s).
▷The max. range depends on the baud rate:
Baud rate Range
[kBit/s] [m] [yd]
93.75 1200 1300
187.5 1000 1090
500 400 545
1500 200 220
▷
The ranges may be increased by using repeat-
ers. Do not connect more than three repeaters
in series.

Faults
DANGER
Electric shocks can be fatal! Before working on
possible live components, ensure the unit is discon-
nected from the power supply.
Fault-clearance must only be undertaken by author-
ized, trained personnel.
▷Faults may be cleared only using the measures
described below.
▷
If the PFA does not respond even though all faults
have been remedied: remove the unit and return
it to the manufacturer for inspection.
? Faults
! Cause
• Remedy
? The 7-segment display does not light up.
! Mains voltage is not applied.
• Check the wiring, apply mains voltage (see type
label).
? The display blinks and indicates P
or
? A bus fault is indicated on the automation
system.
! 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 (Commissioning).
▷ 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, shield-
ing, 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 net-
works are set out in the instructions for the au-
tomation system or, for example, in the “Installa-
tion Guideline for PROFIBUS DP/FMS”, available
from the PUO (PROFIBUS User Organization).
? All the burners are constantly in operation,
regardless of data traffic.
! The PFA is set to manual mode.
• Switch the PFA to “normal operation”.
? The display indicates .
! Profibus module fault.
• Remove the unit and return it to the manufacturer.
? The display indicates
