Description
The Flow Control System FMR Typ 8750 was developed for the control of propellent air for
the pneumatic conveyance of pourable solid media (e.g. plastics granulates) over long
distances. Following its success in this application, the FMR was used in the control of
combustion air and gases (e.g. combustion in ceramic furnaces) and for the control of the
propellent (e.g. air, nitrogen) in pigging installations.
The system consists of
-a control valve Type 2712 with TopControl Continuous Type 8630
-two pressure sensors Type 8323
- and optionally a temperature transmitter.
These components together form a module.
•All operating functions are executed via 3 function keys.
•The operating menu of the FMR is delivered with factory settings.
•The real flow characteristic curve for the current control valve is stored point-for-point in 5
% steps in the memory of the controller.
•The sensors are built into the connecting tubes to the valve.
•To cover a wide variety of control applications, a broad spectrum of nominal diameters
and seat combinations is available.
•The valve seats may be exchanged as required.
•The outlet sections are already integrated in the system.
•The pressure drop over the control valve (acting as a restriction) is measured
continuously by the two pressure sensors. This pressure difference and the valve flow
characteristic are the parameters for determination of the volumetric flow through the
control valve, i.e. for the process value. This measured value is compared with the
setpoint, evaluated in a PID controller and set on the positioner as the new setpoint.
NOTE Change the factory settings of the operating menu only if required by
concrete process conditions.
NOTE Before first commissioning, check the factory settings and set the
process parameters that are still open.
With these settings, the controller parameters are adapted to system
behaviour in the subroutines AUTO and Process-TUNE.
ATTENTION! On assembly of the module, the intake sections to EN ISO 5167-1
must be observed (shown in the section "Intake sections to
EN ISO 5167-1").

Sequence of steps from assembly up to commissioning of a system with FMR
•Check the operating conditions against the technical data for the system Type 8750
delivered.
•Assemble the control system in the existing system in observance of the required intake
section; check the connection points for leaktightness (pressure test, etc.).
•Wire the electrical cable connectors according to PIN allocation and make these
connections.
•Make the control air connection and attach a silencer to port 3 if necessary; check the
control connection for leaktightness.
•Connect the operating voltage and control air.
•Inform yourself about the operating strategy and the functions of the operating keys.
•Check the factory settings of Type 8750 and carry out the necessary process dependent
settings in the operating menu.
•Start X.TUNE (AUTOTUNE) for determinaton of the parameters for the positioner.
•Set all parts of the system to the operating condition (control air, operating voltage,
external signals, medium flow, etc.).
•Prepare PROCESS TUNE for automatic determination of the controller parameters.
Step 1 Activate the menu item for PROCESSTUNE (P.CO TUNE \ P.TUN ON).
Step 2 Determine a value for the setpoint step.
Step 3 Check the starting value for the setpoint step and if necessary set
this starting value more exactly.
Step 4 Enter the setpoint step by hand. When the entry is finally confirmed, the
function PROCESS TUNE is started automatically.
•Check the orderly running of PROCESSTUNE.
•Register and evaluate the control results of the system with the FMR.
ATTENTION! Inform yourself on the intended use and safety notes; comply with
internal works safety instructions and accident prevention regulations;
make ready any safety equipment required.
ATTENTION! Before starting assembly, disconnect the existing system from the
voltage supply and release the pressure.
NOTE All necessary operating steps for processing the step sequence are
described in these operating instructions. For more advanced
questions, please use the documents supplied on the CD or the
Internet.

Installation of an FMR in a system
•Any orientation of installation of the FMR may be chosen, but the TopControl should
preferably be above.
•In order to avoid turbulent flow at the pressure transmitter, a suitable intake section must
be provided immediately upstream of each FMR (dimensions to EN ISO 5167-1 as per
sketch); the outlet section is already integrated into the FMR.
•Make sure that piping is well aligned and that the FMR is installed without stress. The
piping must be fixed or supported as necessary.

•The electrical connections to the FMR are made with circular connectors at the connector
plate of the TopControl.
•The signal connections between the pressure transmitters and the TopControl have
already been made in the factory (with M8 circular connectors).
•In the case of the FMR version with optional temperature transmitter, the signal
connections have also been made in the factory with M8 circular connectors.
•If signals go out from the FMR, an M16 circular connector wired as per PIN allocation plan
is required. The M16 circular connector may be obtained from Bürkert.
•Wire an M12 circular connector as per PIN allocation plan for the power supply. The M12
circular connector may be obtained from Bürkert.
•Make the signal connection to the TopControl with the M16 circular connector.
•Make the connection to the power input of the TopControl (e.g. from a power supply unit)
with the M12 circular connector.
ATTENTION! Observe the direction of flow (arrow on the valve fitting); the inlet flow
to the control valve may as a general rule only be under the seat.
ATTENTION! Thoroughly clean all connection points prior to installation.
ATTENTION! Make sure that all connections are leaktight.

Operating levels of the FMR
Operation of the FMR is done via the process operating level and via the configuration level.
The process operating level is active after
switching on the device. In this level, one can
switch between the AUTOMATIC and MANUAL
modes by briefly pressing the manual/automatic
key. In the AUTOMATIC mode, the position or
process control runs; in the MANUAL mode, the
valve may be opened or closed by hand. To
change to the configuration level, one must press
the M/A key for 5 s.
In the configuration level, the basic
functions and, if needed, supplementary
functions are specified on first
commissioning. During configuration,
the process falls into a stationary state
with the parameters immediately prior to
switchover. Return to the process level
is done from the menu item END.

Procedure for checking and setting
After the operating voltage is switched on, there appears for ca. 5 sec the display EEPROM;
after this, the system automatically activates the process operating level with the display

Deactivate the air leak compensation
Activate the leak compensation
Background: during transport of pourable solids,
there arises at a rotary valve an air leakage
dependent on the pressure. The air flow through
the controller unit is the sum of this leakage and
the air flow of the conveying pipe. Q
FMR
= Q
air leak
+ Q
conv.path
Reading in the air characteristic once with the
conveying pipe closed enables the air leakage to
be compensated during conveying, increasing the
precision of flow control.
The program for automatic registration of the
leakage characteristic is started with P.CO LEAK
→LEAK MEAS
Then hold the key depressed for 5 sec.
NOTE: to break off leakage measurement, press

Balancing the pressure transmitter
The pressure transmitters p1 and p2 may be
calibrated to increase the measuring precision at
small pressure differences.
For this purpose the conveying pipe behind the
process valve (FMR) must be closed off and the
controller unit pressurized with a constant pressure.
Calibration of the zero point:
pressure < 10 % of the sensor range,
Calibration of the upper calibration value:
pressure > 55 % of the sensor range.
