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 FLOW SWITCH INSTRUMENTS D-6300/FS

2.1 General

The digital D-6300/FS Flow Switch instruments of M+W Instruments GmbH are thermal

measurement devices for mass flow, where the alarm function of the multi-functional

display is used for the adjustment of an individual switch-point depending on the mass

flow of a gas or gas-mix.

ATTENTION!

Flow Switches can be operated in 2 different switching variants and each variant has 3

different setting options. Upon the Flow Switch dispatch the variant for the output of the

switch-point is defined! The evaluation of the switching signal must have a minimum input

resistance of 10 kΩ.

The Flow Switches are equipped with a digital electronic multi-bus pc-board and consist

of a micro-controller with peripheral circuitry for measuring 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 RS232 communication line.

The Flow Switch 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)

The micro switches and LED’s on top of the individual 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.

Tel.: +49 8166 9921 0

Fax: +49 8166 9921 22

Email: sales@mw-instruments.com

When the instrument needs to be returned please include a description of the damage in

a closed envelope.

ATTENTION!

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, operating pressure as well as the

output signal.

−The instruments contain electronic components which are sensitive to electrostatic

discharges (ESD). Contact with electronically charged persons or objects could

possibly endanger these components or even result in their failure.

−While installing the instrument take care of the arrow marking on the instrument’s flow

body, determining the flow direction.

−Ensure that all piping is absolutely clean and without any damage. It is recommended

to install an inlet filter in front of the instrument.

−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 the system has to be checked that there is 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 meters for high flow rates (D-6380/FS and bigger) in another

mounting position you should get in contact with your distributor or with 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) it has to be

ensured 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.

2.3 Operation and Maintenance

When the power is switched on a warm-up period of at least 30 sec is required allowing

the instrument’s thermal stabilisation. Afterwards the instrument will work with an

accuracy of approximately 4% FS. It takes around 30 minutes until the optimal stability is

reached and the instrument will work with an accuracy of < 2% FS. This is supposed to be

performed with or without gas flow. To avoid creating gradients it is recommended that

gas and ambient temperature are kept at the same level (max ΔT approx. ± 2…3 °C).

Otherwise the accuracy of this thermal measurement could be affected in an

unpredictable manner.

Be sure that the specified pressure ratings have been applied. Pressure surges, as may

occur during the system pressurisation, must be avoided. When starting up, always bring

the instrument gradually up to the level of operating conditions.
