VAV700Multi-functional air volume fl ow controller with integrated web server

1 Technical documentation VAV700 • Date: 01/2015 • www.schneider-elektronik.com

Product descriptionHigh-speed adaptive control system for variable control of room supply air and room exhaust air volume fl ows, particularly suitable for clean rooms and laboratories.

The integrated dual port switch allows a simple and effective Ethernet-networking of volume fl ow controllers (supply air/exhaust air) and fume hood controllers FC700 within the laboratory and the complete building. The parameterisation and the data access occur with a standard web browser. Native BACnet®/IP with trendlog and intrinsic reporting are optional implemented. Modbus® is supported as further fi eld bus systems.

Extended requirements afford a radiator respectively a coo-ler as well as pressure maintenance of the room. Besides these performance features the multi-functional volume fl ow controller VAV700 balances all network-connected consu-mer loads and calculates the necessary room supply air re-spectively room exhaust air needed for the maintenance of the parameterised room air exchange (e. g. eightfold).

A high-speed control algorithm compares the setpoint with the actual value measured by a differential pressure trans-mitter and controls the air volume quickly, precisely and steadily, independent of pressure fl uctuations in the duct system. The system data and setpoint values (volume fl ow, temperature, pressure, humidity, etc.) are freely program-mable and will be saved voltage fail-safe in the FLASH.

Up to three freely confi gurable static differential pressure sensors allow the detection and regulation of the room pres-sure of two independent rooms besides the volume fl ow re-gulation.

Up to four free slots allow a fl exible and cost-effective adjustment of the controlling respectively measuring task to the customer specifi c requirements.

Operation and activation mode (setpoint setting) analogue, digital, BACnet®, Modbus®

The multi-functional volume fl ow controller VAV700 is available in seven activation versions with the setpoint setting as the main distinctive feature. The following operation and activation modes are supported (depending on the version):

Block diagramPicture 1 shows the block diagram and the piping of the static differential pressure sensor with a maintenance-free measuring system.

All plugs of the sensors and actuators are pre-assembled and directly pluggable on the outside of the FC700-housing. That means an immense reduction of the assembly time and a simplifi cation of the commissioning. The high speed hysteresis-free actuator is operated in the proven direct drive mode and guarantees high control accuracy, highest durability and lifetime.

The pre-assembled CAT6/CAT7-cable for the Ethernet-networking will be plugged in the dual port switch and the system is ready for commissioning.

.

NetworkingThe networking offers maximum fl exibility and safety. The connection to the building management system offers the complete ventilation control and monitoring of all laborato-ries.A fl exible network-adjustment is simply realised by modu-lar extension cards. Besides the already integrated native BACnet® (IP or MS/TP) and Modbus® (IP or MS/TP) LON® is also available. The fi eld bus boards can be retrofi tted simply and at any time for all SCHNEIDER LabSystem products.

Internet technology with integrated web serverThe FC700 possesses an integrated web server for a simple data exchange and to improve the system security and it communicates via the Internet protocol TCP/IP. The operation and parameterisation is carried out by a laptop with a standard web browser. For this reason a simple circuit-entering into multivendor capable building management systems is guaranteed and the system is therefore prepared for all future applications.

Web browser operationThe internal web sites of the integrated web server can be visualised via a standard web browser. Adjustments and parameter can be simply changed. By using a standard web browser project-dependent fi les are no longer necessary to access the central building control system worldwide and at any time. The internal visualisation software VIS7000 reduces signifi cantly the system costs (data points) on the building management system level and can assume the building management functions if necessary.

Native BACnet®-IPThe building management system is provided with a multitude of data and therefore allows an optimsed requirement planning and process control. Native BACnet® (IP or MS/TP) guarantees a fast, simple and direct connection to the building management system without additional gateways. Our own BACnet® stack developed by SCHNEIDER guarantees maximum fl exibility. We support the read-out and storage of trendlog data as well as intrinsic reporting.

Simple wiring and fast commissioning

A simple and fast wiring and commissioning are the main parameters to reduce signifi cantly the installation and assembly costs. The dual port switch integrated on the CPU-board allows an easy daisy chain wiring with pre-assembled cables.

Picture 2: Daisy chain wiring

The wiring can be executed radially as well.Therefore the connection of the bus cable is omitted. All standard cables, e. g. sensor cable, actuator cable, etc. are pre-assembled and externally pluggable.

The commissioning, confi guration, diagnosis and visualisation of all system data (e. g. control time, damper position and setpoint settings) occur centrally through the network by a control unit via PC with standard web browser or decentrally via infrared interface of the graphic indication and operation panel.

Extension modules

Up to four free extension slots are available on the motherboard of the VAV700-controller. The controller can be easily and cost-effectively extended to further functions.

Customer specifi cally developed extension modules for special measuring, control and regulation functions on demand.

The following extension modules are available:

EMSC Automatic sash closing module

Picture 4: Four free slots

Slot 6 (right) is always equipped with the sensor board and slot 5 with the CPU board. The slots 1 to 4 (left to right) can be freely equipped with the above listed extension modules.


Building management system

The building management system (BMS) balances the air requirement of the complete building and can additionally run a plausibility check on all room controllers. Day/night-switch, visualisation of status and fault detections as well as actual values can be simply integrated. Remote main-tenance and fault remote diagnosis as well as an air con-sumption recording relating to the laboratory respectively to the fume hood with an individual accounting can be realised as well.

Up to three position independent sensors

For VAV700 up to three position independent static sensors (-100-300 Pa) are available and can be freely confi gured. Because of the high sensibility and resolution a volume fl ow range of 1:15 can be adjusted smoothly.

The function classifi cations exhaust air, supply air and room pressure to the static differential pressure sensors are freely confi gurable. Therefore the controller can be simply and fl exibly adjusted to all kind of applications. All data and measuring values are available at any time by the connected network.

Picture 3: Sensor board with three static differential pressure sensors



Heating and cooling of the laboratory

The heating and cooling of laboratories via appropriate heating and cooling registers can also be executed by FC700. The appropriate analogue and Triac outputs to regulate the heating and cooling valves will be made availabe by the extension modules EM10 to EM40. The power supply of the valves is provided by FC700 and the independent closed loop which is already implemented by default.

All measured room values e. g. temperatures, humidity, pressure are available as actual value via network.

Picture 5: Valve activation

Project planning

The project planning and parameterisation software PRO7000 is compatible to Windows and is used for a simple and fast commissioning. Parameterisation of devices can be executed from a central point for the entire room respectively the entire building. All data of the connected devices with integrated web server by SCHNEIDER can be indicated via standard web browser and entries can be done password protected.

Visualisation

All relevant data is available for the building management system (BMD) via the network and can be used for facility management functions. A better planning and utilisation of the ressources as well as a reduction of energy and operational costs are the significant characteristics.

Laboratory occupation plans, night setback and individual accounting of the air consumption data, energy-efficient operation as well as the safety improvement via remote maintenance and remote diagnosis of the fume hood controller and the volume flow controller for room supply air and room exhaust air are the outstanding advantages of the network technology with an integrated building management system (BMS).

The visualisation software module VIS7000 is the reasonable extension of PRO7000 and allows the simple creation of room graphics and a free alignment of single devices (e. g. fume hood, volume flow controller, etc.) in the room. This is a cost-efficient integral system solution with functions of the building management system.

The touchscreen controller PAD7000 developed by SCHNEIDER is especially adjusted to the requirements of the laboratory ventilation system and adopts the functionalities of the building management system. Special templates are freely disposable. Trendlog and intrinsic reporting are implemented as well. Networking via BACnet®

(IP or MS/TP) and LON® is supported.

Functional descriptionVolume fl ow measurement with a position inde-pendent static differential pressure transmitter

Using a suitable measuring device (maintenance-free measuring system (MD), Venturi measuring tube (VD), measuring tube (DD) or measuring cross (KD) the diffe-rential pressure is determined by a position independent differential pressure transmitter. The measurement is very accurate and stable over the entire measuring range of -100 - 300 pa , making it possible to regulate a volume fl ow range of upt to 1:15.

Unlike the thermo-anemometric measuring principle (dyna-mic sensor), air does not fl ow through the static differen-tial pressure transmitter, making it particularly suitable for measuring in dusty and contaminated (corrosive) media (its suitability should be checked in individual cases). The sui-tability of the thermo-anemometric measuring principle for such media is very limited, as the sensor becomes dirty or is affected by corrosive air and thus measurement may be very imprecise or inaccurate.

Volume fl ow setting VMIN, VMAX

The volume fl ow adjustment and parameterisation is done via laptop (with software PC2500) or via the web browser in the network. The demanded volume fl ow is entered as a numeric value. Thereby means:

Function Volume fl ow Reference signal w VMIN minimum 0(2) < w ≤ 10 V DCVMAX maximum w = 10 V DC

The allocation of the analogue demand signal w to the volu-me fl ow Vmin and Vmax illustrates the VAV-curve (variable operation mode).

Demand signal w (setpoint setting via analogue input A-In)

With the demand signal w (setpoint selection), the volume fl ow can be constantly switched between VMIN and VMAX, at which the following is always true: 0 m3/h = 0(2) V DC, VMAX = 10 V DC

The regulated volume fl ow actual value (A-Out) is availa-ble as 0(2) - 10 V DC output voltage (with extension board EM10) or via network. Various master/slave operating modes can be implemented with this signal.

Shield factor (C-value)

The shield factor is the design and geometry dependent constant of the used measuring device. The volume fl ow is calculated according to the following formula:

Parameterisation of the volume fl ow controller

The volume fl ow controller can be parameterised via laptop (with software PC2500) or web browser in the network as follows:

Function Signifi cance RemarksVMIN minimum

volume fl ow≥ shield factor B * 1,5 (rule of thumb)

VMAX maximumvolume fl ow

+9990 m3/h to- 9990 m3/h

Typ default (setpoint value = analogue or digital)

The controller confi guration specifi es the operating mode (analogue or digital).

In network operation mode (variable volume fl ow control-ler = VAV) the volume fl ow is regulated linearly via network depending on the setpoint setting.

In analogue operating mode (variable volume fl ow con-troller = VAV) the volume fl ow is regulated linearly based on the analogue demand signal w (setpoint value via analogue input A-In).

In digital operating mode (constant volume fl ow controller = CAV) the volume fl ow is regulated in stages based on the digital inputs In1 and In2. Up to four different volume fl ows (VMIN, VMED and VMAX and VEMERGENCY) can be regulated. An analogue demand signal is not required.

In both operating modes (VAV and CAV) pressure fl ucta-tions in the duct system are recognised and automatically regulated.

Offset for integrating of constant loads

With the offset value a fi xed value is programmed (+9990 to - 9990 m3/h) that is added to the volume fl ow setpoint (+ offset = increases the volume fl ow setpoint, - offset decre-ases the volume fl ow setpoint). This makes it possible to integrate constant loads.

A constant difference between supply and exhaust air is therefore possible in master/slave mode. This function is particularly important in airtight rooms (e.g. clean rooms).

Function description ● Analogue operational modeNotes on controller dimensioning (dimensions and volume fl ow)

Due to measurement accuracy it must be ensured that at the minimum volume fl ow VMIN the fl ow velocity in the volu-me fl ow controller does not fall below 2 m/s.

Due to noise development, in laboratory applications it must be ensured that at the maximum volume fl ow VMAX the fl ow velocity in the volume fl ow controller does not exceed 7,5 m/s.

The volume fl ows VMIN, VMED, VMAX are freely programma-ble within the range 50 - 25.000 m3/h, but care must be taken to ensure suitable volume fl ow controller dimensions with regard to the volume fl ow range while at the same time taking the fl ow velocity into account.

Analogue operation mode Variable volume fl ow controller (VAV)

In variable volume fl ow operating mode the desired volume fl ow is predefi ned by a demand signal w (setpoint setting). The value range of the demand signal is 0(2)...10V DC.

The volume fl ow can be constantly controlled between VMIN und VMAX with the demand signal w, at which the following is always true:

0m3/h = 0(2) V DC 0(2) < VMIN ≤ 10 V DC VMAX = 10 V DCAlways note:1. Minimum control value VMIN = shield factor B * 1.52. Values < VMIN are not regulated3. With reference signal w < 0.3 V, the damper will be SHUT

In the example diagram 1 the volume fl ows VMIN = 300 m3/h and VMAX = 750 m3/h are programmed. The volume fl ow actual value signal (A-Out2) correlates with the regulated volume fl ow.The advanced setpoint at analogue output A1-Out is available and the value to be achieved by the actual value. An advanced setpoint is very effective for intercon-necting modules with their own operating time requiring a stable signal (e.g. control of frequency inverters, etc.).

The volume fl ow does not fall below VMIN, even when the demand signal w lies below the corresponding VMAX signal (in the example diagram 1: w = 4V).

Forced control via digital inputsThrough appropriate wiring of the digital inputs In2, In3 and In4 the functions described in table 1 can be executed di-rectly.

The wiring of the digital inputs is as follows: 0 = contact open (no current) 1 = contact closed (under current)

Contact open = 0, contact closed = 1.

The variable operation mode (analogue setpoint setting via A-in) is only possible, if the digital inputs are In1 = 0 and In2 = 0, which means that they are not under current (contact open). All functions are freely confi gurable under considera-tion of the digital inputs.

The available operating stages are shown in diagram 2 and table 2. 1 level, 2 level, 3 level or 4 level operation can be easily implemented by direct control of the digital inputs.

The volume fl ows are programmed to the values VMIN = 875 m3/h, VMED = 1750 m3/h and VMAX = 2150 m3/h. VMED must always lie between VMIN and VMAX. The volume fl ow actual value signal (A2-Out) correlates with the regulated volume fl ow.

The following is valid for the volume fl ow actual value:

SHUT = 0m3/h = 0(2) V DC 0(2) < VMIN ≤ 10 V DC VMAX = 10 V DC

Master-slave-sequence control with equal per-centage ratio in VAV operation

This master-slave sequence control is always used if the room pressure must be maintained at an equal percentage ratio of supply and exhaust air. Suffi cient replacement fl ow of the difference between the supply and exhaust air must be ensured in this operating mode.

The master controller is programmed with the volume fl ow values VMIN and VMAX and the demand signal w is added on directly. The volume fl ow actual value of the master con-troller provides the demand signal for the slave controller, which can be programmed with other VMIN and VMAX volu-me fl ow values depending on the application.

If the master controller is mounted in the supply air and the slave controller in the exhaust air and positive (+) room pressure is required, the slave controller must be program-med with the lower percentage volume fl ow values VMIN and VMAX in relation to the master controller.

If negative (-) room pressure is required, the slave control-ler must be programmed with the lower percentage volume fl ow values VMIN and VMAX in relation to the master con-troller. Sample settings for master-slave controllers:

Slave (+) Master Slave(-)VMIN 240 300 360VMAX 600 750 900

The master slave sequence control applies for both equal percentage ratio and constant difference between supply and exhaust air. The demand signal w (A-In) is added on to the master controller and the volume fl ow actual value A1-Out (with extension module EM10) provides the demand signal for the slave controller.

This ensures that the slave controller always follows the master controller. For safety reasons, master/slave se-quence control must always be given preference over par-allel control.

Diagram 4: Sequence control (master-slave) with con-stant difference

In the sample settings, the volume fl ow values VMIN und VMAX of the slave (+) controller were programmed to -20% (negative room pressure) in relation to the volume fl ow va-lues of the master controller. For negative room pressure the volume fl ow values VMIN and VMAX of the slave (-) con-troller must be programmed to +20 % in relation to the volu-me fl ow values of the master controller.

The equal percentage ratio between supply and exhaust air is maintained throughout the entire volume fl ow range of VMIN to VMAX.

Master-slave sequence control with constant difference in VAV operating mode (analogue ope-rating mode)

This form of master/slave sequence control is used when room pressure with a constant difference between supply and exhaust air is required. This operating mode is selected for airtight rooms (e.g. clean rooms).

The master controller is programmed with the volume fl ow values VMIN and VMAX and the demand signal w (A8-in) is added on directly. The volume fl ow actual value (A2-out) of the master controller provides the demand signal for the sla-ve controller, which is programmed with the same volume fl ow values VMIN and VMAX, depending on the application.

In addition, the offset is also programmed in the slave con-troller. If the master controller is mounted in the supply air and the slave controller in the exhaust air and positive (+) room pressure is required, the slave controller must be pro-grammed with a negative offset.

If negative (-) room pressure is required, the slave controller must be programmed with a positive offset. Sample settings for master-slave controllers:

Slave (+) Master Slave(-)VMIN 300 300 300VMAX 750 750 750Offset -150 0 +150

In this example, the volume fl ow values VMIN and VMAX of the slave (+) controller and the slave (-) controller were pro-grammed with the volume fl ow values of the master con-troller. For negative room pressure the offset of the slave (-) controller must be programmed with +150 m3/h.

The constant difference between supply and exhaust air is maintained over the entire volume fl ow range of VMIN to VMAX.

Master-slave sequence control in CAV operating mode (digital mode)

In CAV operating mode the digital inputs of the master con-troller are wired to control the different operating stages (see table 3). The volume fl ow actual value A1-Out (with ex-tension board EM10) of the master controller provides the demand signal for the slave controller.

DDC/BMS control

If the master controller is controlled via a DDC/BMS (de-mand signal w or digital control) the volume fl ow actual va-lue of the slave controller can be added on as feedback and therefore used to monitor the functioning of both volume fl ow controllers (master and slave).



Multi functional applications in analogue or network operating mode • Heating and/or cooling

Volume fl ow controller network operating modes

The variable volume fl ow controller VAV700 is especial-ly developed for the networked operation and possesses different operating modes which can be confi gured via the network. The following controller types are implemented :

Variable volume fl ow controller 2-level constant volume fl ow controller Balancing volume fl ow controller Room volume fl ow differential controller

Multi-functional applications in the network operating mode (BACnet, Modbus®)

Besides the on the previous pages described classical vo-lume fl ow controller operating modes e. g. variable volume fl ow controller, 3-level constant volume fl ow controller, ba-lancing volume fl ow controller and room volume fl ow dif-ferential controller the following additional multi-functional applications are implemented on the VAV700:

Via the available extension modules any customer specifi c applications can be cost-effectively implemented.

Actual value collection of room pressures

The volume fl ow controller VAV700 has up to two free static differential pressure transmitter -100 - 300 Pa which can be freely confi gured e. g. for a pressure cascade control loop or for measuring of room pressures.

Additionally, any analog values 0 (2) ... 10 VDC can be con-nected to the analog inputs of the expansion modules (eg EM10) and are available as BACnet objects on the network.

ETHERNET TCP/IP

The room plan 1 shows the networking by default with the Internet protocol TCP/IP via Ethernet. Due to the high data transfer rate it is possible to network any number of sub-scribers. The response time of the linked subscribers (e. g. room supply volume fl ow controller) is suffi ciently secured even during heavy data traffi c.

WiringThe integrated dual port switches of VAV700 and FC700 al-low a simple and fast daisy chain wiring with pre-assembled CAT6/CAT7 patch cables and therefore reduce the assem-bly and installation costs signifi cantly. Therefore the con-necting of the bus cable is omitted and all standard cables like sensor cable, actuator cable, etc. are pre-assembled and pluggable on the outside.

Balancing

The volume fl ow controller VAV700-IP balances the re-quired room supply air and room exhaust air independent-ly according to the laboratory exhaust air and controls the calculated value self-suffi ciently. If the added exhaust air of the fume hoods is not suffi cient for the maintenance of a defi ned room air exchange rate (e. g. room air exchange rate = quadruple or octuple) the room exhaust air volume fl ow controller raises the volume fl ow as long as the reque-sted room air exchange rate is reached.

The room supply air volume fl ow controller follows the total room exhaust air, reduced by a fi xed value or a percentaged reduction. Therefore the required low pressure in the labo-ratory according to DIN 1946, part 7 is guaranteed for all operating conditions. The supply of the volume fl ow control-ler with 24 V AC has to be provided by the customer.

The optional room management controller RMC700 can be connected directly to the network via LON® or Modbus® and regulates e. g. day/night operation per room. Status and operation information (temperature, humidity, pressure) can be indicated additionally on the graphic display.

Commissioning via Internet protocol TCP/IP

For a simple data transfer and to improve the system se-curity VAV700-IP has an integrated web server and com-municates via the Internet protocol TCP/IP by default. The operation, parameterisation and commissioning occur via laptop with standard web browser.

The commissioning can occur decentrally for all linked sub-scribers via a standard web browser or directly via infrared interface at the fume hood with a laptop and the installed software PC2500.

The internal websites of the integrated web server can be visualised worldwide with a standard web browser. Therefore a simple remote maintenance can be realised. The internal visualisation software VIS7000 reduces signifi cantly the system costs (data points) on the building management system level and can assume the building management functions if necessary. Extension modules

Any function extensions can be simply and modulary realised by the subsequently pluggable extension modules. Besides the sash closing function (extension module EMSC) miscellaneous input and output modules (analogue and digital) for measuring value collection (temperature, humidity) respectively for controlling heating and cooling valves as well as fi eld bus modules (LON®) are available. The controller can be arbitrarily extended to further functions besides the sash closing function (extension module EMSC).

All extension modules are embedded in the networking and provide the data and measuring values via the Internet protocol TCP/IP.



Room scheme 2 ● Volume fl ow controller VAV700/FC700 with BACnet-IP networking and room visualisation

The room plan 2 shows a networking with native BACnet®-IP protocol. The BACnet®-IP protocol is increasingly esta-blished as de facto standard for the building automation. Due to the high data transfer rate it is possible to network any number of subscribers. The response time of the linked subscribers (e. g. room supply volume fl ow controller) is suffi ciently secured even during heavy data traffi c.

Native BACnet®-IP

A BACnet® stack implemented in the 700 product series allows the direct communication with the business management system RMS700 by SCHNEIDER. Gateways are not required anymore and due to the direct implementation of the BACnet® stack to the CPU board the term „native BACnet®“ has been created.

BACnet® is a multivendor capable interface for management systems and allows the simple implementation and visualisation of functions.

Extension modules


List of objects and object typesThe PICS list (Protocol Implementation Conformance Statements) for BACnet® applications can be required or downloaded from our website: www.schneider-elektronik.com.

Room visualisation

The project planning and parameterisation software PRO7000 is compatible to Windows® and is used for a simple and fast commissioning. Parameterisation of devices can be executed from a central point for the entire room respectively the entire building. All data of the connected devices with integrated web server by SCHNEIDER can be indicated via standard web browser and entries can be done password protected.

The visualisation software module VIS7000 is the reasonable extension of PRO7000 and allows the simple creation of room graphics and a free alignment of single devices (e. g. fume hood, volume flow controller, etc.) in the room. This is a cost-efficient integral system solution with functions of the building management system.

The touchscreen controller PAD7000 developed by SCHNEIDER is especially adjusted to the requirements of the laboratory ventilation system and adopts the functionalities of the building management system. Special templates are freely available. Trendlog and intrinsic reporting are implemented as well.

A permanently enhanced variety of modular boards is available for the individual process application. With the extension modules EM10 to EM50 the following functions can be realised:

Room temperature controlling with setpoint setting

Room humidity controlling with setpoint setting

Activation of heating and cooling valves for static radiators respectively cooling ceiling or fan coils (with EM30, 6 relay outputs for fan activation, step 1 to 3).

With this technology sustainable and energy-effi cient offi ce and functional buildings can be realised which can be certifi ed according to LEED or DGNB.

All relevant data are available via TCP/IP, BACnet®/IP over Internet or for a central building management system. Decentral closed loops adopt the independent room controlling functions without intervention of the building management system which mainly dynamically visualises the processes and rooms.

The room pressure maintenance of laboratory and clean rooms as well as the energetic capacity accounting is easily realised.

The visualisation software module VIS7000 allows the simple creation of dynamic room graphics and a clear exposition on the PC. This is a cost-efficient integral system solution with functions of the building management system.

The room plan 2 shows the connection of the volume fl ow controller VAV700-AD (analogue input) with up to 9 fume hoods (Ain 1 to Ain 9) with the laboratory controller LCO500. The laboratory controller regulates up to eight freely con-fi gurable volume fl ow controllers for room supply air/room exhaust air (Aout1 to Aout8). The internal switching power supply (optional) provides a maximum of 8 volume fl ow con-trollers with supply voltage 24 V DC which simplifi es the planning and the implementation is more cost-effective.

The analogue inputs Ain1 to Ain10 will be summed-up and can be combined to miscellaneous groups on the analo-gue outputs Aout1 to Aout8. Thereby any confi gurations are possible. Therefore it is possible to regulate independently e. g. several laboratories (max. 8) with one room supply air volume fl ow controller each and 10 fume hoods at most. Like it is shown in room plan 2 an additionally room exhaust air can be confi gured besides the room supply air. Each room exhaust air volume fl ow controller requires an analo-gue input (recirculation actual value room exhaust air).

Networking with building management system

A cost-effective and simple connection to the multivendor capable building management system (BMS) can be reali-sed via the network by an optional fi eld bus module (LON®, BACnet® or Modbus®).

Via the BACnet® bus board a native BACnet® can be re-alised which means that no gateways are necessary to possibly implement protocols and data. Therefore a full compatibility as well as a simple and fast commissioning is guaranteed.

With the extension of the digital fault warning inputs (optio-nal) all fault warnings of the connected fume hoods will be gathered and sent via network to the building management

system (BMS).

The laboratory controller LCO500 fulfi lls the functionality of a DDC-substation respectively a router.

The following data are available as network variables in the business management system:

readout of the exhaust air actual values of the fume hoods Ain1 to Ain10 readout of the summed-up room balances

(room supply air/room exhaust air) setpoints for 8 analogue outputs readout of the 8 digital outputs setting of the 8 relay outputs

Therefore special functions like day/night switchover of the fume hood controller, regulation and monitoring of the room control unit, temperature regulation as well as controlling of the heating and cooling valves are simply realisable.

Extended functions like remote maintenance are realisable as well. By day/night switchover, retrieval and comparison of the individual exhaust air actual values each fume hood can be checked regarding this function.

The optional room management controller RMC700 can be connected directly via LON® or Modbus® to the network and regulates e. g. day/night operation per room. Status and operation information (temperature, humidity, pressure) can be additionally indicated on the graphic display.

The laboratory controller LCO500 combines the analogue technology with the advantages of the bus technology and offers a cost-effective, fl exible and secure regulation and vi-sualisation per room via the building management system.

Connection diagram VAV operating mode

The analogue lead signal is connected by the transmitter (e.g. temperature sensor, setpoint device) respectively by the laboratory controller LCO500, the DDC or BMS. The vo-lume fl ow actual value signal of the master-VAV generates the lead signal of the slave-VAV.

The volume fl ow actual value signal of the slave-VAV can be connected as a feedback signal to the laboratory controller LCO500, the DDC or BMS, whereby the functionality of the complete master-slave-sequence control can be checked. A forced control is possible as well (please refer to table 1 on page 9). The allocation digital input/function is freely programmable.

Connection diagram CAV operating mode

The different CAV operating steps are apparent in table 2 on page 10. The volume fl ow Vmax is adjusted if both digital inputs (In1 and In2) are not under current, which means that the contacts are open. The current feed of In1 adjusts Vmin and of In2 adjusts VEmergency. The allocation digital input /function is freely programmable.

The master is adjusted during CAV operating mode and the slave during VAV operating mode. The slave follows the ac-tual value of the master. The feedback of the volume fl ow actual value signal to the laboratory controller LCO500 or DDC/BMS is possible as well.

Connection diagram network operating mode

The volume fl ow controller VAV700 is designed as a net-work controller by default. The system is completely inde-pendent by direct connection with the fume hood controller FC700. The internal communication runs via Modbus® IP or via BACnet®-IP respectively LON® on demand. All relevant data and parameters are exchanged on a suffi cient rate and the balancing of room supply air respectively the required room exhaust air to maintain the necessary room air ex-change rate is automatically calculated and adjusted via the connected volume fl ow controllers VAV700.

The integrated Ethernet-dual port switch allows a fast and cost-effective daisy-chain-wiring with pre-assembled ca-bles. The commissioning and parameterisation of all con-nected devices (FC700, VAV700, etc) are carried out from an arbitrary central point.

All relevant data like actual values and parameterised set-points are available for the BMS connected to the network.

BACnet®-cable specifi cations (MS/TP, RS485)

In a BACnet®-network (MS/TP, RS485) is only daisy-chain-wiring allowed (no free topology, like LON®)

MS/TP (master slave/token-passing)

The master slave/token passing-protocol has been develo-ped by ASHRAE and is only available for BACnet®.

The connection to the fi eld bus occurs via the cost-effective interface EIA RS 485. MS/TP can be operated in a pure ma-ster slave-mode, with token delivery between equal nodes (peer to peer token passing methods) or in a combination of both methods.

EIA RS 485 standard

The EIA RS 485 standard defi nes a bidirectional bus sys-tem with up to 32 participants. Given that several transmit-ters work on a common wire, it has to be guaranteed by a protocol that maximum one data transmitter is active at any time (e. g. MS/TP). All other transmitters have to be in a high-resistance condition during this time.

The ISO-standard 8482 standardises the cable topology with a maximum length of 500 m. The participants have to be connected to this daisy-chained bus cable ( line topolo-gy) via a branch line with a maximum length of 5 m. A cable termination with termination resistors (2 x 120 Ohm) on both ends is basically necessary, to avoid refl ections.

If no data transfer takes place (data transmitter inactive) a defi ned resting level should be adjusted on the bus system. This can be achieved by connecting wire B over 1 k Ohm to ground (pull down) and wire A over 1 k Ohm to + 5 V DC.

During installation each wire of the twisted pair (A and B) has to be necessarily applied alone. The correct polarity of the twisted pair has to be necessarily regarded because a false polarity causes the inversion of the data signals. Espe-cially in case of diffi culties in connection with the installation of new end devices each failure detection should begin with checking the bus polarity.

Generally recommended is the laying of daisy-chained shielded wires and to ground the shielding one-sided (GND).

Network cable specifi cations ● BACnet® ● Modbus®



Network extension in bus and daisy chain-struc-ture

The bus cable is laid in one string. The nodes are connected via short branch line (maximum 5 m).

For a safe transmission in networks with bus/daisy chain topology the following issues have to be regarded:

The bus wire has to be connected to bus terminator at both ends (R1 = R2 = 120 Ω)

The second terminator is necessary in either case

The maximum cable length of the branch lines must not exceed 5 m

The maximum cable length is 500 m

Ethernet-cable specifi cation

Ethernet-cable Cat-6A is suitable for structured wiring of all connected devices in the fi eld bus technology for an increased bandwidth requirement of 10 Gigabit-Ethernet (10GBASE-T).

Cat-6A is suitable for transmission frequencies up to 500 MHz and distances up to 100 m as well as downward com-patible to existing network protocols.

Cat-6A is defi ned by the international standards committee ISO/IEC (International Organization for Standardization/In-ternational Electrotechnical Commission).

Modbus®-cable specifi cation (RS485)

Modbus® is an application log for the information exchange between fi eld modules with integrated Modbus® controllers.

The Modbus® protocol is settled on the application layer of the OSI reference model and supports the master slave mode between intelligent devices. .

The Modbus® protocol defi nes the information type on which the Modbus® controllers communicate. It describes how a Modbus® controller approaches another controller via request, how this controller answers and how failures are detected and documented.

The Modbus® protocol functions on request answer-base and offers different services which are specifi ed by func-tion codes. The Modbus® protocol determines during the communication how each controller gets to know the device address and recognises the information which belong to it. Besides it defi nes the releasing actions and which informa-tion the Modbus® controller can gather from the information fl ow. If an answer is requested then it will be confi gured in the controller and is sent by the Modbus® protocol to the appropriate station.

The Modbus® can be cost-effi ciently realised via EIA RS 485 and is therefore excellently suitable for the laborato-ry internal networking. The wiring described for the EIA RS 485 standard (please refer to BACnet®) has to be absolutely complied with.

SCHNEIDER products in networked systems

Due to the retrofi t fi eld bus modules for LON®, BACnet® and Modbus® by SCHNEIDER the complete system is very fl exible, individual and cost-effi ciently adaptable to different networks.

We offer the complete system from one source without compatibility problems.

For detailed cable specifi cations please refer to SCHNEI-DER LabSystem handbook, chapter 10.0.

For the laboratory supply air (volume fl ow controller made of steel) the measuring nozzle DD (standard version) or optional the measuring cross with additional shield KD is delivered.

Given that the volume fl ow control range VMin, VMax and VNom is different for each measuring system the volume fl ow va-lues for each nominal size of the specifi c measuring device is listed below.

Planning instruction for volume fl ow determination:Consider volume fl ow in relation to fl ow velocity v VMIN = volume fl ow at a fl ow velocity v = 1 bis 2 m/s VMAX = volume fl ow at a fl ow velocity v = 6 m/s (recommended) VNOM = volume fl ow at a fl ow velocity v = 10 bis 12 m/s

Due to the fl ow noise of the volume fl ow VMAX the fl ow velocity v should not overrun 6 m/s during the labora-tory operation (exhaust and supply air). In case of exceeding this value the required noise level of < 52 dB(A) according to DIN1946, part 7 can only be reached with complex sound absorption. The maximal adjustable volume fl ow VMAX should always be about 40 % below VNOM.
