Short Operating Instructions
for commissioning the
The Flow Control System FMR Type 8750
Note
These short operating instructions describe in brief the most important steps in the installation
and commissioning of the Flow Control system FMR Type 8750.
The system Type 8750 consists of a control valve Type 2712, a TopControl Continuous Type
8630, two pressure sensors Type 8323 and optionally a temperature transmitter.
The present short operating instructions are limited to the essential steps for
- installation, commissioning, configuration and self-optimization,
- error messages, malfunctions and error elimination.
For more advanced or detailed questions, please use the more detailed documents supplied
on the CD or to be found on the Internet.

Intended use
The Flow Control System Type 8750 shall be used exclusively for the control of volumetric
flow or flow velocity in gaseous media. Only the medium stipulated in the contract shall be
allowed to enter the device. Before putting into operation, changes in the medium must be
discussed and clarified with us. The device shall be operated only at the values stated in the
chapter „Technical Data“ and given on the rating plate.
The safety devices on the system shall under no circumstances be circumvented. The
required personal protective equipment must be worn and the accident prevention regulations
complied with. The components installed at the time of commissioning shall not be
disassembled without a specific written work instruction.
Read carefully through all chapters of these short instructions and the operating instructions
for the components of this system, which are to be found on the CD or on the Internet under
www.buerkert.com
Observe the notes given in the chapter „General Safety Notes".
The device shall be operated exclusively by trained specialists who have been instructed by
us. Electrical work on the device shall be performed only by a trained, qualified electrician
who has also been instructed by us. During electrical work, the main switch must be switched
off and secured.
Conversions and modification to the device on the user's initiative are prohibited for safety
reasons. On exchange of faulty or worn parts, only original spare parts shall be used.
The work instructions in the individual chapters must be complied with and the safety notes
observed under all circumstances. If work instructions are not followed in the exact sequence,
or safety notes or symbols are ignored, all warranties will become void.
ATTENTION! Indicates information that must be followed. Failure to do this could
endanger your health or the functionality of the device.
NOTE Indicates important additional information, tips and recommendations.

Disposal
ATTENTION! •Keep to standard engineering rules in planning the use of and
operating the device.
•Installation and maintenance work are only allowed by qualified
personnel using suitable tools.
•Observe the current regulations on accident prevention and safety
for electrical devices.
•Before intervening in the system, always switch off the power
supply.
•Note that in systems under pressure, piping and valves may not be
loosened.
•Take suitable precautions to prevent inadvertent operation or
damage by unauthorized action.
•After interruption of the electrical or pneumatic supply, make sure
the process is restarted in a well-defined, controlled manner.
ATTENTION! Transport and store the appliance in its original packing only.
ATTENTION! When disposing of the appliance, observe the national standards for
refuse disposal.

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.
