Checking the usage
PFA 700
Fieldbus interface for interworking of up to nine automatic
burner control units PFU 760 or PFU 780 to industrial communication networks using PROFIBUS DP. The PFA700
can be plugged into the pre-wired module subrack BGT
SA-9U/1DP, together with the automatic burner control
units.
PFA 70
Fieldbus interface for interworking of up to eight automatic
burner control units PFU 780 to industrial communication networks using PROFIBUS DP. The PFA710 can
be plugged into the pre-wired module subrack BGT SA8U/1DP, together with the automatic burner control units.

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 removing the perforated plates A from between the module subracks,
and inserting a rack-mounted fan B underneath the
module subracks.

A
Wiring the BGT
Disconnect the system from the electrical power sup-
ply.
▷
Use a resistor with low impedance at high frequencies
for grounding the BGT.
▷
Ensure an equipotential bond between the various
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%, <10mA.
▷ 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 program-
B
mable logic controller (PLC).
▷
The steps required to copy the file are described in
the instructions for the PLC.
A
Configure the PROFIBUS DP using the appropriate
tools for the PLC you are using.
▷
The PFA will automatically identify the baud rate (max.
1.5 Mbit/s).
132
mm
200 mm
58
mm
465 mm
▷ 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 repeaters. Do
not connect more than three repeaters in series.
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. 100m
▷
(328 ft).

Replacing the PFA
▷
The old PFA 700 (Order No. 84395100 – see type
label) can be replaced with the new PFA 700 (Order
No. 84395101 or 84395102) in the module subrack
BGT SA-9U/1DP (Order No. 84402283).

▷ To increase the EMC interference immunity, the new
Profibus plug supplied must be used for the new PFAs
(Order No. 84395101 or 84395102).
Check the voltage.
4 Read off the Profibus address on the old PFA.
5 Accept and set the Profibus address on the new PFA
– see page 4 (Address setting).
6 Install the new PFA – see page 4 (Installing the
PFA).
7 Check the operating parameters for manual mode on
the new PFA and adjust where applicable.
8 Replace the Profibus plug on the BGT with the Profi-
bus plug with shielding capacitor – see page 12
(Profibus plug for PFA).
