1 Scope of this manual

1.1 Introduction

This manual covers the IQ+FLOW® series mass flow/pressure meters/controllers for gases. Examples of the instrument series are shown in the pictures below. This manual includes product information, installation instructions, operation, maintenance and troubleshooting.

1.2 Product description

The IQ+FLOW® series is one of the smallest mass flow, chip based, instruments of its kind for applications with pressure conditions up to 10 bar (145 psi) and temperatures between 5 to 50 °C (41 to 122 °F). Due to the use of micro system technology, ultra compact flow controllers are realised with dimensions of only 20 x 40 x 60 mm. The (IQF) flow controllers are able to measure and control flow rates of 10 mln/min FS up to 5 ln/min FS. The (IQP) pressure controllers are available in ranges from 0.3 to 150 psi

(0.02 to 10 bar). The IQ+FLOW® series has a modular concept with combinations of 20 mm footprint modules, available as single instruments, but also as multiple channel arrangements. A very compact manifold (IQM) system can be constructed, with one multi-channel digital pc-board (per 3 channels) in a single housing. Additional filters, control valves and shut-off valves are available with the same footprints to meet customer demands. The IQF flow sensor is a fast-response chip sensor, with the main advantage of fast and reliable control response. This is possible due to the MBC3-based pc-board and the flow sensor, which output signal very accurately corresponds with the real flow behavior.

Communication with the devices can be either in analog mode or digital over RS232 or RS485. Communication over RS232 is established with the Propar (FLOW-BUS) protocol. With digital operation over RS485 a bus-system with multiple instruments can be set up. Modbus RTU/ASCII and FLOW-BUS protocols are supported (some exceptions for multi-channel versions, see section 3

).

1. Check IQ+FLOW® properties

Before installing it is important to read the attached label and check:

Instrument type:

- gas (IQF) red label or

- pressure (IQP) yellow label Flow rate Fluid to be measured / controlled Up- and downstream pressure Input and output signals Temperature

IQ(F/M) - Gas Flow IQP - Pressure

Output/Setpoint

A – 0…5 Vdc B – 0…10 Vdc F – 0…20 mA G – 4…20 mA

IQ+FLOW® instruments are designed for dry, clean, inert and non-explosive gases. Do not use the instruments for gases that do not belong to this category.

The tested pressure is stated on the instrument with a red-coloured sticker. Before installation, make sure that the test pressure is in accordance with normal safety factors for your application. If there is no Pressure Testing Sticker on the device or if the test pressure is incorrect, the instrument should not be mounted in the process line and be returned to the factory.

For reliable measurement always make sure that the fluid stream is clean. Use filters to ensure a clean, moisture- and oil- free gas stream. Recommended pore-size: 7 µm. If back flow can occur, a downstream filter is recommended too. Be aware of the pressure drop caused by using filters.

For IQ+FLOW® the upright position is preferred. When using an IQ+FLOW® instrument in up- or downward position make sure to “zero” the instrument prior to use (see section 2.10). Avoid installation in close proximity of mechanic vibration and/or heat sources. The housing of the instrument is according to class IP40, which means that the instrument is suitable for indoor (dry) applications, like laboratories or well protected (OEM) housings.

Install the IQ+FLOW® instrument in the line, in accordance with the direction of the FLOW arrow. The arrow for flow direction is indicated on the body of the instrument. If applicable follow the guidelines of the supplier of the fittings. Special types of fittings are available on request.

Compression type fittings

For leak tight installation of compression type fittings make sure that the tube is inserted up to the shoulder in the fitting body and that no dirt or dust is present on tube, ferrules or fittings. Tighten the nut finger tight; while holding the instrument, then tighten the nut one turn.

10-32 UNF fittings

Tighten the 10-32 UNF fittings according to the instructions of the supplier of the fittings.

Only use 1/16” tubing with a straight and clean cut without burrs to ensure leak tightness. Preferably deburr the tubing prior to installation. A new ferrule connection must be made for each new adapter to ensure leak-tightness and minimum dead volume, due to variances in the adapter dimensions.

Mounting downported instruments

For downported instruments make sure that the seals are present at the bottom, that the surfaces are undamaged and that they are dry and free from dirt or dust.

2.5 Leak check

Check the system for leaks before applying (fluid) pressure. Especially if toxic or other dangerous fluids are used!

Electrical connections must be made with a standard cable or according to the IQ+FLOW® hook-up diagram. Several hook-up examples and standard cables are found in section 3.

IQ+FLOW® instruments are powered with +15…+24 Vdc.

Electrical connections must be made with standard cables or according to the applicable hook-up diagrams. These documents can be found at: http://www.bronkhorst.com/en/downloads

The instruments contain electronic components that are susceptible to damage by electrostatic discharge. Proper handling procedures must be taken during installation, removing and connecting the electronics.

The instruments described in this manual carry the CE-mark and are complient with the EMC requirements. However compliance with the EMC requirements is not possible without the use of proper cables and connector/ gland assemblies. Bronkhorst High-Tech B.V. recommends the use of their standard cables. These cables have the right connectors and if loose ends are used, these will be marked to prevent wrong connection. When using other cables, cable wire diameters should be sufficient to carry the supply current and voltage losses must be kept as low as possible. When in doubt: contact your distributor.

When connecting the system to other devices (e.g. to PLC), be sure that the integrity of the shielding is not affected. Do not use unshielded wire terminals.

Analog operation (single channel versions only)

For analog operation refer to the “Hook-up diagram IQ+FLOW®” or use an RJ-45 loose-end cable (7.03.419) to connect the required signals.

Digital RS232 operation

Digital operation over RS232 can be established when using the following setup. Using a RS232 cable or a USB-RS232 converter with a PC will allow you to use (free) Bronkhorst® software for Windows, such as FlowDDE and FlowPlot. See also section 3.4.

Digital RS485 operation

With digital operation over RS485 a bus-system with multiple instruments can be set up. See section 3.5 for possible systems.

Micro-switch operation (single channel versions only)

Using the micro-switch on the instruments, several actions can be monitored and started. The green LED is used for status indication. The red LED is used for errors/warnings/messages. The micro-switch can be used to start several actions, such as auto-zero, restore factory settings and bus-initialisation actions, if applicable. See specific zero-procedure below and section 3.3 for more details.

Multi-functional switch

Status LED

Error/Warning LED

Rotary switch operation (multi-channel versions only)

Select the communication type and Baud rate with the “COMM. TYPE” switch. Select the node address with the “MSD” and “LSD” switch (e.g. MSD = 1 and LSD = 9 selects node 19 for channel 1, but also node 20 and 21 for channels 2 and 3). See section 3.3

for more details.

Do not apply pressure until electrical connections are made. When applying pressure to the system, avoid pressure shocks in the system and increase pressure gradually. Also decrease pressure gradually when required.

In systems for use with toxic or other dangerous fluids, purging for at least 30 minutes with a dry, inert gas (like Nitrogen or Argon) is absolutely necessary before use. After use with toxic or other dangerous fluids, complete purging is also required before exposing the system to air.

Warm-up time

Let the IQ+FLOW® warm-up for at least 30 minutes for best accuracy.

2.10 Zeroing

The zero point of each instrument is factory adjusted. If required the zero point can be re-adjusted over RS232 or by means of using the micro-switch. Procedure for zeroing by-micro switch (not for pressure meter/controller):

Warm-up, pressure up the system and fill the instrument according to the process conditions. Make sure no flow is going through the instrument by closing valves near the instrument. The setpoint must be zero. Press micro-switch and hold it. After a short time the red LED will go ON and OFF, then the green LED will go ON. At that moment release the micro-switch. The zeroing procedure will start at that moment and the green LED will blink fast. The zeroing procedure waits for a stable signal and saves the zero. If the signal is not stable, zeroing will take long and the nearest point to zero is accepted. The procedure will take approximately 10 seconds. When the indication is showing 0% signal and the green indication LED is burning continuously again, the zeroing action was successful.

Each IQ+FLOW® instrument is factory calibrated. Bronkhorst High-Tech B.V. certifies that all instruments meet the rated accuracy. Calibration is performed using measurement standards traceable to the standards of the Dutch Metrology Institute (VSL). Calibration certificates are included in the shipment. When operated properly (clean gas, no pressure shocks, no vibrations, no thermal shocks, etc.), regular maintenance is not required. However, periodical inspection, recalibration or verification of the accuracy may be subject to individual requirements of the end-user.

It is recommended to turn on power before applying pressure on the instrument and to switch off power after removing pressure.

Turn on fluid supply gently. Avoid pressure shocks and bring the instrument gradually up to the level of the actual operating conditions. Also switch off fluid supply gently.

When operating the instrument through the analog interface it is possible to connect the instrument simultaneously to RS232 for reading/changing parameters (e.g. settings or fluid selection).

Refer to the “Hook-up diagram IQ+FLOW®” or use an RJ-45 loose-end cable (7.03.419) to connect the required signals.

When using a Bronkhorst readout unit use only an RJ-45 cable (7.03.236) in combination with the RJ-45 to 9-pin sub-D converter (7.03.376). With these items the pin configuration is unchanged.

3 Basic operation

3.1 General

An IQ+FLOW® instrument must be powered with +15…+24 Vdc according to the applicable hook-up diagram, supplied with the instrument. The instrument can be operated by means of:

Analog interface: 0…5 Vdc; 0…10 Vdc; 0…20 mA or 4…20 mA (single-channel versions only) Digital RS232 interface (FLOW-BUS (Propar) protocol) Digital RS485 interface (Modbus RTU, Modbus ASCII or FLOW-BUS protocols)

By default the instrument is set as specified. The table below lists the supported interfaces for single-channel and multi-channel versions.

3.2 Analog operation

Analog operation is only possible with single-channel IQ+FLOW® instruments. Multi-channel instruments can only be operated digitally. At analog operation the following signals are available:

Measured value (analog output) at pin 2 Setpoint (analog input/setpoint) at pin 3

The valve output is no longer available as analog signal with IQ+FLOW®. The selected analog interface (0…5 Vdc; 0…10 Vdc; 0…20 mA or 4…20 mA) can be found in the model key of the instrument. Refer to Section 2.13

Hook-up

For analog operation either an RJ-45 loose-end cable or an RJ-45 to 9-pin sub-D converter may be used to connect the required signals.

3.3.2 LED functions

The LEDs on top of the instrument can also be used for manual operation of some options. The green LED will indicate in what mode the instrument is active. The red LED will indicate error/warning situations.

3.3.3 Rotary switch operation (multi-channel versions only)

The IQ+FLOW® multi-channel instruments are equipped with rotary switches for selection of communication type, baud rate and node address.

Node address switches

With the two 'NODE ADDRESS' switches the node address of the instrument channels can be selected. The 'MSD' (Most Significant Digit) sets the first digit (tens), the 'LSD' (Least Significant Digit) sets the second digit (units). The node address of channel 1 is set with the switches, the channels 2 and 3 receive 'node address' + 1 and 'node address' + 2 respectively (e.g. MSD = 1 and LSD = 9 selects node 19 for channel 1, but also node 20 and 21 for channels 2 and 3).

IQ+FLOW 9.17.04514

Bronkhorst High-Tech B.V.

Connecting an IQ+FLOW® instrument to a COM port of a pc requires a special cable (7.03.426) which changes the appropriate pin configuration. Optionally use an RS232 to USB2.0 converter (9.02.122) to connect to a USB port. Use the split cable (Y-adapter

7.03.241) in combination with the Plug-in Power Supply (7.03.424) for powering the instrument.

Instead of using a COM or USB port, it is also possible to connect the RS232 pinning manually using the loose-end cable (7.03.419), typically for connection to PLC or microcontroller devices.

3.4

Digital operation adds a lot of extra features (compared to analog operation) to the instruments, such as:

Up to eight selectable fluids (if installed) Direct reading at readout/control module or host computer Testing and self diagnosis Identification (serial number, model number, device type, user tag) Adjustable minimal and maximal alarm limits (Batch) counter

Basic RS232 operation

3.4.1 Hook-up

3.4.2 Dynamic Data Exchange (DDE)

RS232 communication can be used for operating the instrument using the Bronkhorst FlowDDE server application. Dynamic Data Exchange (DDE) provides the user a basic level of interprocess communication between Windows applications. FlowDDE is a DDE server application. Together with a client-application, either self-made or with a SCADA-program from third parties, it is possible to create an easy way of data exchange between the flow controller and a Windows application. For example, a cell in Microsoft Excel could be linked to the measured value of the IQ+FLOW® and when the measured value changes, it will be updated automatically in the Excel spreadsheet.

3.4.3 FlowDDE

The FlowDDE server also offers a lot of test facilities and user-adjustable settings for efficient communication with the connected flow/pressure meter or controller. How to setup a DDE link with FlowDDE is described in the help-file of the FlowDDE application. Programming examples are available for making applications in: Visual Basic, LabView and Microsoft Excel.

3.4.5 FlowDDE parameter numbers

Reading/changing parameter values via FlowDDE offers the user a different and user-friendly interface to the instrument. A DDEparameter number is a unique number in a special FlowDDE instruments/parameter database and not the same as the parameter number from the process on an instrument. Node-address and process number will be translated by FlowDDE to a channel number.

An instrument parameter can be changed by using the application name: 'FlowDDE' with only:

topic, used for channel number: 'C(X)' item, used for parameter number: 'P(Y)'

3.4.6 Baud rate setup

Make sure that the instrument's baud rate corresponds with the baud rate of the application the instrument is communicating with. For single-channel instruments the selectable baud rates are 9K6, 19k2, 38k4, 57k6 and 115k2 Baud; for multi-channel instruments the selectable baud rates are 38k4 and 115k2 Baud.

3.5

Basic RS485 operation

This section is limited to the description of the interface between the IQ+FLOW® instrument with a master device. IQ+FLOW® instruments always serve as slaves in a Modbus system. There is no mutual communication between Modbus slaves; only between master and slave. The master device is for example a pc.

3.5.1 Hook-up

The illustrations below show examples of a number of IQ+FLOW® instruments in an RS485 bus-system. When the power consumption is more than 15W, two seperated power networks are required due to the maximum power supply of 15 W for one PiPS.

3.5.2

When using a pc to communicate with IQ+FLOW® instruments only the FLOW-BUS protocol is supported by Bronkhorst software. When using Modbus operation, software from third parties, such as LabView, ModScan or a Modbus PLC must be used to serve as Modbus master.

Software

3.5.3 Slave address, baud rate and parity setup

The IQ+FLOW® instrument is configured as specified on order. If there is a need of changing any of the specified settings, see the tables below for the supported configurations. The default selections are presented in bold.

Single-channel versions

In case the baud rate or node address of an IQ+FLOW® instrument needs to be changed, this can be done with the micro-switch or by changing the settings in the 'Configuration Mode'. Other parameters can be changed only in the 'Configuration Mode'. For changing the mentioned parameters with the micro-switch see Section 4.2.5. When using the 'Configuration Mode' to change these settings, activate the 'Configuration Mode' by pressing the micro-switch at start-up according the description in Section 3.3.1. In 'Configuration Mode' the baud rate and bus type are set to 38k4 and RS232 FLOW-BUS (Propar). Change the appropriate parameters as described in Section 4.2.5. When finished, deactivate the 'Configuration Mode' using the same procedure. Now the instrument is ready to use in desired configuration with the adjusted baud rate, node address or parity.

Basic parameters and properties

3.6.1 Introduction

Most instrument parameters can only be accessed with digital communication. For each communication protocol the instrument parameters are accessed differently. When using Bronkhorst® software programs FlowView or FlowPlot, easy access is provided to the mostly used parameters by menu interfaces. When using other communication methods the addressing method for the supported communication protocol is presented for a number of basic parameters in a table as shown below:

Type

Unsigned char 1 byte character Unsigned char[x] x byte array (string) Unsigned int 2 byte unsigned integer Unsigned long 4 byte unsigned long Float 4 byte floating point

Access

R The parameter is read-only RW The parameter can be read and written RW

Range

Some parameters only accept values within a certain range: [x] Minimum value of the range. [y] Maximum value of the range.

The parameter is protected and can only be written when the 'Init Reset' parameter is set to 64. See section 4.1.1 for more details.

FlowDDE Parameter number within FlowDDE. Refer to section 3.4

FLOW-BUS

Within the FLOW-BUS protocol (Propar when using RS232) parameters are divided into a 'Process' and a 'Parameter' number. To address parameters using the FLOW-BUS/Propar protocol write both numbers: [Pro] Process number [Par] Parameter number

Modbus

Parameters can be read or written via the Modbus protocol by specifying either the PDU Address or the register number. The PDU Address is a hexadecimal number (identifyable by the '0x' prefix), which corresponds to the decimal register number minus one, e.g. PDU Adress 0x0000 equals register number 1, PDU Adress 0x000A equals register number 11 etc.): [address] Hexadecimal PDU address [index] Decimal register number For the Modbus protocol every two bytes are addressed separately.

3.6.2

The list below provides the most basic parameters for digital communication with the instrument.

Measured Value (Measure)

The 'Measured Value' indicates the amount of mass flow or pressure metered by the instrument. The signal of 0...100% will be presented in a range of 0...32000. The maximum measured value output is 131.07 %, which is: 41942. A floating point variable of the measured value, 'Fmeasure', is also available in the capacity and capacity unit for which the instrument has been set, see

section 4

Setpoint

The 'Setpoint' is used to set the required mass flow rate or pressure for the controller. The signals have the same range as the measured value, only the setpoint is limited between 0 and 100% (0…32000). A floating point variable of the setpoint, 'Fsetpoint', is also available in the capacity and capacity unit for which the instrument has been set, see section 4.

Basic measurement and control parameters

.

3.6.3 Basic identification parameters

User Tag

The 'User Tag' parameter allows the user to give the instrument a custom tag name, with a maximum of 16 characters. It is advised however to limit the user tag name up to 7 characters when using the Bronkhorst® E-7000 readout and control modules. These modules can display the tag name of an instrument only up to 7 characters.

Customer Model

This parameter is used to add extra information to the model number information, such as a customer-specific model number.

Serial Number

This parameter consists of a maximum 20-byte string with instrument serial number for identification, for example: 'M1111111A'.

BHT Model Number

This parameter shows the Bronkhorst® instrument model type information.

manuals_english/917023_operation_instructions_digital_instruments.pdf

After power-up the control mode will be set to 'Analog input' or 'BUS/RS232', depending on the customer's default setting for analog or digital operation. Except when the actual control mode setting is other than 0, 1, 9 or 18 the actual control mode setting is maintained. For more information see parameter 'IOStatus', section 4.2.2.

4.1.2 Fluid information

The following parameters give information about the selected fluid range.

Fluid Number

The 'Fluid number' is a pointer to the set of calbration parameters. Each selectable fluid has its own set of calibration parameter values. Parameter value 0 = fluid 1 and parameter value 7 = fluid 8. Up to eight fluids can be stored in an instrument. Default value = 0 (fluid 1).

Fluid Name

This parameter consists of the name of the selected fluid number, e.g. 'Air'.

Fluid Unit

The 'Fluid Unit' can be read by parameter 'Capacity Unit'. This parameter contains the unit in maximal 7 characters.

Fluid Capacity (@100%)

Capacity is the maximum value at 100% for direct reading in sensor readout units.

Fluid Capacity (@0%)

This is the capacity zero point for direct reading in sensor readout units.

4.1.3 Advanced measurement and control parameters

Measured Value (Fmeasure)

Floating point variable of the 'Measured Value'. The 'Fmeasure' variable shows the measured value in the capacity and capacity unit for which the instrument has been set. The 'Fmeasure' parameter is dependent of 'Capacity', 'Capacity Unit', 'Sensor Type' and 'Capacity 0%'.

Setpoint (Fsetpoint)

Floating point variable of the 'Setpoint'. The 'Fsetpoint' variable shows the setpoint value in the capacity and capacity unit for which the instrument has been set. The 'Fsetpoint' parameter is dependent of 'Capacity', 'Capacity Unit', 'Sensor Type' and 'Capacity 0%'.

Valve Output

This parameter is the signal coming out of the controller, used for driving the valve. 0…16777215 corresponds with approximately 0…60 mAdc.

4.1.4 Controller parameters

The controlling algorithm for the valve handled by the micro-controller consists of several parameters which can be set. Although many parameters could be accessed, Bronkhorst® advises not to change these parameters because during manufacturing the controller is optimized. Changing of controller settings should be performed by or under supervision from trained service personnel only.

The picture below shows the basic controller diagram of the digital instrument. It consists of a standard PID controller with a number of add-ons. Basically, when a faster or slower controller response is needed, only the controller speed (Kspeed) or PID-Kp should be changed.

Kp (PID-Kp)

PID controller proportional action, multiplication factor.

Controller Speed (Kspeed)

This parameter is the controller speed factor. PID-Kp is multiplied by this factor.

Ti (PID-Ti)

PID controller integration action in seconds. This value should not be changed.

Td (PID-Td)

PID controller differentiation action in seconds. The default value is 0.0. This value should not be changed.

Open from Zero control response (Kopen)

Controller response when starting-up from 0% (when valve opens). Value 128 is default and means: no correction. Otherwise controller speed will be adjusted as follows:

New response = Old response·1.05

(128-Kspeed)

Normal Step response (Knormal)

Controller response during normal control (at setpoint step). Value 128 is default and means: no correction. Otherwise controller speed will be adjusted as follows:

New response = Old response·1.05

(128-Knormal)

Stable Situation control response (Kstable)

Controller response when controller is stable (within band of 2% of setpoint). Value 128 is default and means: no correction. Otherwise controller speed will be adjusted as follows:

New responce = Old responce·1.05

(128-Kstable)

4.1.5 Display filter

The output signal of an IQ+FLOW® instrument (measured value) is filtered. The filter has dynamic behaviour: when a change in sensor signal is detected, the measured value will be less filtered than when the sensor signal is constant and stable. There are two filter constants: Static Display Factor and Dynamic Display Factor. These two factors can be transformed into time constants using the following formula:

The measured value is filtered with a first order low pass filter with a filter time constant between the two ô values.

4.2.2 Changing default control mode

Instruments are delivered with either analog or digital signal as default, depending on customer's requirement. After every (powerup) reset the instrument will return to its default control mode. The default control mode can be changed with the following parameter:

IOStatus

Bit 6 [7…0] represents the former analog jumper. 1 = default control mode is analog 0 = default control mode is digital

Procedure for changing default digital operation to default analog operation:

Read 'IOStatus' Add 64 to the read value Write 'IOStatus'

Procedure for changing default analog operation to default digital operation:

Read 'IOStatus' Subtract 64 from the read value Write 'IOStatus'

4.2.3 Disabling micro switch (single-channel versions only)

It is possible to disable the micro-switch on top of the instrument. This can prevent undesired use of this button. Disabling the micro-switch can be performed with the following parameter:

IOStatus

Bit 3 [7…0] is used to disable the micro switch. 0 = micro switch disabled 1 = micro switch enabled

Procedure to enable the micro switch:

4.2.4 Setting digital output (multi-channel versions only)

The IQ+FLOW® multi-channel pc-board is equipped with three digital outputs. The digital outputs can be used for driving shut-off valves (for instance). The digital outputs can be read or written via the parameter 'IO Switch Status'. The parameters can be set as indicated in the value table below. Note that this parameter is channel-independent. Each output can be accessed via all channels. E.g. by writing this parameter via channel 2, it is possible to open/close a shut-off valve located at channel 1.

4.2.5 Changing slave address, baud rate and parity

Changing node address or baud rate by micro-switch operation

Press the micro-switch 5x briefly with intervals of max. 1 second in normal running/operation mode. Within the timeout period of 60 seconds it is possible to start changing the node address and baud rate of the instrument.

Instrument returns to normal running / operation mode. Changes are valid when they are made within the time-out times.

Value zero will be indicated by a period of 1 sec off (0.5 sec off + 0,5 sec off). When value zero is wanted, press switch shortly and release it again within 1 sec.

Before each action of flash-counting, the LEDs to be used for counting will flash in a high frequency. (Pattern: 0.1 sec on, 0.1 sec off). As soon as the switch is pressed-down, this LED (or both LEDs) will be off and the counting sequence will start.

When changing any of the parameters below in normal running/operation mode the communication with the instrument may be lost. After a restart the instrument is available for communication on the newly selected parameters. When in doubt activate the 'Configuration Mode' (38k4 and RS232 FLOW-BUS (Propar)) using the micro-switch.

Changing node address, baud rate or parity in 'Configuration Mode' or in normal mode

The procedure for changing the baud rate, node address or parity for a FLOW-BUS or Modbus configuration over RS485 is described in Section 3.5.3 (single-channel versions only). In the list below the selectable bus parameters with corresponding values are presented.

Fieldbus 2 selection

This parameter sets the fieldbus type. Parameter value 0 = FLOW-BUS, 1 = Modbus RTU, 2 = Propar, 3 = Modbus ASCII

Fieldbus 2 address

Set the node address at any of the allowed values listed in the table in Section 3.5.3, e.g. '3'.

Fieldbus 2 baud rate

Set the baud rate at any of the allowed values listed in table in section Section 3.5.3, e.g. '19200'.

Fieldbus 2 medium

Select the communication medium. Parameter value 0 = RS232, 1 = RS485

Fieldbus 2 parity

Set the parity for Modbus communication. Parameter value 0 = None, 1 = Odd, 2 = Even.

5 Troubleshooting and service

5.1 General

For a correct analysis of the proper operation of an instrument it is recommended to remove the unit from the process line and check it without applying fluid supply pressure. In case the unit is dirty or clogged, this can be ascertained immediately by loosening the fittings and inspecting visually. Energizing or de-energizing of the instrument indicates whether there is an electronic failure. After energizing, fluid pressure is to be applied in order to check behaviour. If there should be suspicion of leakage, do not disassemble the sensor for inspection but contact your local distributor for service or repairs.

5.2 LED indication

The red LED on the instrument gives error or warning information.
