1 SHORT FORM START-UP
All necessary settings for this instrument are already performed at M+W Instruments
GmbH. Following the next steps carefully is the quickest way to get the instruments
operational in your own system:
Connection
Make sure your PC or PLC is connected to the RS232 interface by means of the correct
cable.
The maximum cable length for communication via RS232 must not exceed 10 m!
Power Supply
Make sure that the instrument or interface is connected to the power supply:
+15 Vdc up to +24 Vdc (please check on instrument label)
COM-Port Settings
Use settings [38400,n,8,1] for your COM-Port:
Baud rate = 38400 Baud, no parity, 8 data bits, 1 stop bit.
In case of any trouble during installation or to set up the communication Bronkhorst®
programs like FlowDDE or Hyperterminal (available in MS-Windows) could be very useful.
Please refer to chapter 4 how to use FlowDDE.

2 DIGITAL INSTRUMENTS
2.1 General
The digital instruments of M+W Instruments GmbH are measurement devices for thermal
mass flow and control of gases. They are equipped with a digital electronic multi-bus
pc-board and consist of a micro-controller with peripheral circuitry for measuring,
controlling and communication. The flow signal is measured directly in the gas flow,
digitized and processed by means of the internal software (firmware). The measured and
processed values can be output through the analog interface or through the digital
communication line (RS232 or optional fieldbus interface). For controllers the setting for
the actuator is calculated by the firmware. The setpoint can be given through the
analogue interface or through the digital communication line.
Digital instruments have a lot of setting parameters for signal processing, controlling and
many extra features and thus a wide range in use. Reading and changing of these
settings is only possible via RS232 or a fieldbus, except for measured value, setpoint and
valve output, which is also possible through the analogue interface (depending on
parameter setting).
Digital instruments can be operated by means of the following options:
1. Analog interface (0…5 Vdc / 0...10 Vdc / 4…20 mA / 0...20 mA)
2. RS232 interface (connected to COM-Port by means of special cable at 38400 Baud)
3. FLOW-BUS interface
4. PROFIBUS DP interface
5. DeviceNetTM interface
6. Modbus-RTU interface
Depending on the pre-settings options 1 and 2 are always present on multi-bus
instruments. An interface to any available fieldbus is optional.

Page 8 off 34
The operation via analogue interface, RS232 interface and an optional fieldbus can be
performed at the same time. A special parameter called “control mode” indicates which
connection is controlling the instrument: analogue or digital (via fieldbus or RS232). The
RS232 interface behaves like the Flow-Bus interface. Even when using more interfaces at
the same time, the reading can be done simultaneously. When changing a parameter
value, the last value send by an interface will become valid.
The micro switches and LED’s on top of the instrument can also be used for manual
operations of some options (see chapter 5):
The green LED indicates in which mode the instrument is active.
The red LED indicates address, baud rate etc. and error/warning in relevant situations.
Scope of Delivery
Immediately upon receipt of the incoming goods the package needs to be checked for any
possible damages and the goods have to comply with the scope of delivery listed on the
packing note. In case of any damages the supplier and the freight forwarder have to be
contacted without delay.
In the event of any discrepancies please get in touch with your local distributor (see
www.bronkhorst.com) or contact us directly:
M+W Instruments GmbH

ATTENTION!
All instruments for return must have a fully filled-in “Declaration of Decontamination“.
This declaration has to be attached to the shipping documents, allowing free access on
the outside of the package.
The declaration of decontamination is available on our accompanying CD with each
instrument shipment or it can be downloaded from our website www.bronkhorst.com.
Please mention the instrument’s model code and the serial number on your order, as well
as your VAT number when needed.
2.2 Installation
To avoid personal injury and/or damage to the equipment only trained and qualified
personnel shall perform the installation of the instruments:
Read the instrument’s name plate before installation and check the electrical
connection, flow range, media to be measured, inlet and outlet pressure as well as
input and output signals.
The instruments contain electronic components which are sensitive to electronic
discharges (ESD). Contact with electronically charged persons or objects could
possibly endanger these components or even result in their failure.
Ensure that all piping is absolutely clean and without any damage. It is recommended
to install an inlet filter in front of the instrument.
While installing the instrument take care of the arrow marking on the instrument’s flow
body, determining the flow direction.
Avoid piping with small diameter at high flow rates. When possible no abrupt angles or
other disturbances shall be mounted directly in front of the instrument.

All devices have Withworth pipe threads –type RP –according to ISO228-1
(cylindrical G-threads in inches according to BSPP). The mounting of NPT-fittings will
destroy the inlet threads in the instrument’s body.
Using an inlet pipe with sufficient piping diameter is recommended. The length of the
inlet pipe should be at least 10 times the piping diameter.
Before the first start-up check that the system has absolutely no leakage. If toxic,
explosive and/or corrosive gases are to be used, ensure to purge the system long
enough with a dry, inert gas. This is also required to remove these kinds of gases from
the system.
The instruments’ preferred mounting position is horizontally. Especially when installing
bigger mass flow controllers (D-6371 and bigger) in different ways you should get in
contact with your distributor or M+W Instruments GmbH beforehand.
ATTENTION!
In the event of power loss or when unplugging the main connector the instrument will be
reset into factory settings (=delivery condition).
All instruments described in this manual carry the CE-mark. Therefore they have to
comply with the EMC requirements valid for these instruments. However compliance with
the EMC requirements is not possible without the use of proper cables and
connector/gland assemblies.
In case the instrument is connected to other devices (e.g. power supply) ensure that the
operating voltage complies with the supply voltage given on the name plate and that the
function of the shielding is not affected. M+W Instruments GmbH recommends using
standard cables following the CE-requirements and could supply them when needed.
