Lindab UltraLink FTCU Technical Information

Introduction UltraLink® FTCU is a highly accurate flow controller, which measures the flow with an angled ultrasonic beam which can be calculated and compensated to a very high accuracy over the whole flow range. The method is very stable over time due to that it is not sensitive to dirt and the design minimizes the dust accumulation on the flow sensors. An increased focus on energy saving has led to ventilation systems requiring low min- imum flows. The low flows are a problem since they are very difficult to measure and it is makes it difficult to control the ventilation system. The new technology of UltraLink® makes it possible to measure lower air flows com- pared to today’s products while maintaining measurement accuracy. This offers great advantages for the user in terms of comfort and savings in energy consumption, which is of great interest.

% - Actual value m³/h l/s m/s Setpoint - - Lindab UltraLink Controller FTCU Airflow IP42 Patented Status m³/h l/s m/s °C Mode We reserve the right to make changes without prior notice Description Application The Controller is suitable for measuring and controlling air flow and measuring temperature. Communication is established with analog or digital signals using Modbus. Design The Controller consists of a sensor body attached to a damper body with Lindab Safe gaskets. You are not allowed to make any changes or adjustment to the motor or its end-stops! Two flow sensors are mounted on the sensor body and connected to a display unit. The display unit is mounted on top of a shelf on the damper body. The sensor and damper bodies can rotate relative to each other. This means that the sensors can be optimally positioned independently of the desired position of the display and damper body. Positioning the sensor body correctly after a disturbance is crucial for the measurement accuracy, see page 4 for directions on how to mount the Controller for optimal performance. For FTCU in dimensions 400 — 630, a flange holds the damper and sensor bodies together, the flange must be loosened by unscrewing a nut in order to rotate them. The nut of the flange on the FTCU dimension 400 is 10 mm and the nut on the FTCU dimension 500 — 630 is 13 mm. Note! The flow sensors are placed at a fixed distance to each other and they shall never be removed and not used as handles when turning the sensor body.

Planning The longer distance to disturbance, i.e. the longer straight duct before the Controller, the higher the measurement accuracy will be. However this is not the only factor which affects the accuracy of the measurement. The rotation of the sensor body and hence the positioning of the first flow sensor ( in the direction of the air flow) has an impact on the uncertainty of the measure- ment. It is not recommended to mount the Controller so that the first flow sensor (*) is placed on an outer radius of a fitting, see table below. For example: in the case of the bend in the table below, by rotating the sensor body to position the first sensor according to the first picture (with the first flow sensor on the inner radius of the bend), the Controller can be placed at the distance of two duct diameters from the disturbance to achieve 5 % uncertainty. Positioning the sensor body according to the second picture (with the first sensor on the outer radius of the bend), the Controller must be mounted five duct diameters from the disturbance to achieve the same level of uncertainty. Never use an UltraLink® on the outlet side of a duct fan. Place it on the inlet side or in worst case use a flow conditioner if it must be placed on the outlet side.

SCL SDA GND 3V3 14 15 16 13 We reserve the right to make changes without prior notice Mounting Mount the Controller into the air duct system according to the mounting instructions for Lindab Safe. Do not use the flow sensors as handles when you mount the Control- ler since this may cause damaged and changes in their positions might influence the measurement accuracy. Make sure the airflow arrow is pointing in the direction of the airflow. Position the damper body so that the display is visible from some direction. For future connections it is important that the screws on the lid of the display can be removed. Note the ID-number of the Controller. The ID can be found on the label of the box it was delivered in or on the label on the Controller itself and are the three last numbers of the serial no. Rotate the senor body to the correct position according to the chapter “Planning”, when it is positioned accurately it should be fixed with screws to the damper body in the same way as when you connect ducts and fittings. Controllers of sizes 400 — 630 has a flange which needs to be loosened by unscrewing a nut. This nut is 10 mm for dimension 400 Connections Connect the Controller to a remote terminal unit using RS485 or analog terminals. Connections are made in the terminal board which can be accessed when the lid of the display unit is removed. In the back of the lid there is a picture with a list of the terminals. 1. 24V, power supply (AC G, DC +) * 2. GND, power supply (AC G0, DC -) * 3. +B, connection for Modbus via RS485 4. -A, connection for Modbus via RS485 5. SH, shield 6. GND, ground (system neutral) 7. AO1, analog output 8. AO2, analog output 9. AIN, analog input 10. MO1, connection for motor 11. MO2, connection for motor 12. GND, ground (system neutral) 13. SCL, not used 14. SDA, not used 15. GND, ground (system neutral) 16. 3V3, not used (in case of biasing) *) When using AC terminal 1 (G) should have system potential and terminal 2 (G0) should be system neutral. Recommendations for wiring: Function Cable type 24 V Supply 2-wire, thickness depending on length and load, max. 1,5 mm² RS485 2-wire shielded twisted pair, min. 0,1 mm² (LIYCY cable) Supply the Controller with power from a transformer. and 13 mm for 500 — 630. By loosening the nut the sensor body can be turned into the desired position. Once this is achieved, the flange must be fastened by tightening the nut. To be able to connect cords to the terminal board the rubber cable grommet on the backside of the display unit must be punctured, preferably using an awl or something pointy to ensure tightness to the environment. When the cords have been connected they must be strain relieved. The cords can be attached to the shelf by using cable ties that are attached around cut outs in the shelf. The display unit and actuator is mounted to enable the Controller to be insulated up to 50 mm. You must under no circumstances make any holes or connect anything with screws to the sensor body since this will have an impact on measurement accuracy!

Digital connection Connect A on the RTU to -A on the display unit and B to +B. When connecting more than one Controller in series it is important to keep connecting -A to -A and +B to +B since crossing them will stop Modbus from working. The shield in the RS485 cable should be connected to ground at the transformer and then continuously connect to ”SH” on all the UltraL- inks that are powered from that transformer. If more than one transformer is used on the bus, the shield is broken at each transformer so ”SH” on every product only has connection to ground at the transformer from which its power is supplied. It is recommended to use RS485 cables with twisted pairs and shield, do not supply power in the same cable unless the cable is produced for that purpose. Analog connection When connecting the Controller using analog signals, it is important to connect the analog out signals on the Controller (AO1, AO2) to the analog in terminals on the RTU and the analog in signal (AIN) is connected to the analog out terminal on the RTU. Also make sure to connect the cables to the same analog ground. Bluetooth® connection If the product is equipped with Bluetooth (the Bluetooth logotype is printed on the display unit), wireless communication with the UltraLink can be established. Using a smartphone or tablet with the Lindab UltraLink App, nearby UltraLinks can be identified. It is then possible to connect to one unit and view information regarding that UltraLink, such as active measurements and settings. Mobile app The app “UltraLink” is available on both Android and iOS, it’s free to download from Google Play or App store. Like the PC configuration tool, all settings can be changed via the app. This means all settings can be individually chosen for the specific building, it is therefore necessary to protect the unit with the PIN code in the UltraLink menu. For a discription on how this is done, see page 9. Repeater If the bus is longer than 300 meters or if there are more than 30 devices, the system might need an RS485 repeater (FDS-R, see picture to the right) to be able to communicate in an efficient way. Biasing The master on the bus must have biasing on -A and +B. This is more or less standard on BMS-controllers, but if commu- nication should be established with a conventional computer using a RS485-USB converter, then it is important to make sure that the converter has a bias circuit. If communication fails and you are uncertain about existance of biasing, you can add biasing resistors in the screw terminal on one of the UltraLinks to see if this is the cause of the communication failure. Use 500 - 1000 Ω resistors and connect one resis- tor from -A to GND and one from +B to the 3V3 terminal. It is also recommendedto add a 120 Ω termination resistor between -A and +B on the last UltraLink on the bus to avoid signal reflections.

The transformer power must exceed this. Use only safety isolating transformers. Cal- culation of the current demand I: I = (P1+P2+…+Pn) / U [A] where: Pn is the dimensioned power consumption for each com- ponent [VA] U is the voltage (24) [V]. If the current demand I exceeds 6 A ( which corresponds to approximately 150 VA for a 24 V AC transformer ), it is necessary to use more transformers to prevent overheat- ing. Supply cable sizing The wire size of the supply cable can be determined by calculating the resistance per meter R. The calculation presupposes that a voltage drop of e.g. 2 V is accepted in the supply cable: R(per m) = Udrop / (I × L) [Ω/m] where: Udrop is the accepted voltage drop (2 V) in the cable [V] I is the current [A] L is the longest distance of supply cables from trans- former to a component [m] Power consumption The power consumption for dimensioning supply cables for an UltraLink® Controller is dependant on the size of the product. On page 15 in the table: “Technical data”, the power consumptions of different products are listed. It is not recommended to use a transformer with a higher capacity than 150 VA! Example: Udrop = 2 V, I = 4 A, L = 20 m R (per m) = 2V / (4A × 20 m) = 0,025 Ω/m In the diagram a Wire cross section Area of 0,7 mm² can be read.

% - Actual value m³/h l/s m/s Setpoint - - Lindab UltraLink Controller FTCU We reserve the right to make changes without prior notice Display The display can show useful information both with the diode flashing in green (status light) and with parameters in the LCD. If the product is equipped with Bluetooth, then the diode will also flash in blue every three seconds. If a device has been connected to the UltraLink via Blue- tooth, then the diode will flash in blue every other second. By short pressing the mode button you can change the displayed parameter. If the button is pressed for more than 5 seconds (long press) then the configuration menu will be visible. The arrow at the bottom of the display indicates the current parameter type and unit. For a detailed description on configurating the UltraLink using the mode button on the display, see page 13. Parameter structure The information menu is visible in the display as soon as the device is powered and by default the air flow in m³/h is shown. You can toggle between the different parameters in the menu by short pressing the Mode button. The arrows at the bottom of the menu indicates if the visible value is an actual reading or a set point and also what unit the current value has (if any). The following list of parameters are available; • Actual air flow (m³/h) • Actual air flow (l/s) • Actual air velocity (m/s) • Actual Temperature (°C) • Damper position (%, 100% = fully open) • Current set point (m³/h) • Current set point (l/s) • Current set point (m/s) • Controller’s ID number • Flow rate set point max *) • Flow rate set point min *) *) Only visible if analog control (register 4×071=1) and if the control variable is flow rate (4×070=2). If max and min values are the same the product is working as a constant flow regulator with set point according to that value. Status light The green status light indicates: Mode Function No light Controller is turned off Slow flashing light Motor is regulating Fast flashing light A problem has occurred, error code will be visible in display Constant light Controller is turned on and functioning as normal PIN code UltraLink with Bluetooth must be protected againt unauthorized access by PIN-code, which has to be stated before changes to the settings can be made. It is important to choose and change the code that the product is delivered with (1111), to ensure that no unauthorized changes are made. The Bluetooth radio can be disabled by setting register 4×007 to 0. The code can be changed in three ways: • using the configuration menu in the display, see page 13 for instructions. • connecting a PC via Modbus and using the “Configuration Tool” software. • connect a Bluetooth device and use the “UltraLink” application.

Settings All available settings are presented in the appendix. The settings can be changed via the RS485 bus and can be done from any device and configuration that can communicate using Modbus, but preferably the UltraLink® Configuration tool (See separate documentation). If the products is equipped with Bluetooth the settings can be changed with an app, which can downloaded from Google Play or App Store. Instructions for the most common settings are described below. For more register details see appendix. Digital communication settings Registers 4x001-4x009 are used to configure communication settings. When initializing contact for the first time the default settings will be active; Modbus id: Last three digits in the serial number (also visible in the display if the product has power) Baud rate: 19200 Parity: Odd Stop bits: 1 After updating any of the communication parameters the product needs to be power cycled for the changes to take effect. If communication fails with the default parameters selected in the UltraLink® configuration tool, then the communication settings on the Controller might have been changed previously. Verify the settings in the display (See page 9 for instruc- tions) Control settings The Controller can be read and controlled in several different ways. Primarily you need to set the following registers to determine what variable you will use to control the device and if the control signal comes analog or via bus; 1. Configure register 4×070 for what kind of set point you will control the device with (0 = no control, 1 = damper position, 2 = flow rate) 2. Configure register 4×071 for either bus or analog control of set points (0 = bus, 1 = analog) 3. During operation set points can be applied using registers 4x302 (damper position) and 4×314 (flow) depending on the setting from point 1 above. The set point for damper position has predefined limits 0–100%, where 0% means fully closed and 100% means fully open. The limits for flow has default values according to the table below but can be modified using registers 4×315 and 4×316. The default maximum values corresponds to the upper limit where accuracy is guaranteed. The value can be set higher, but this may cause worse accuracy of the readings. Default values for the relevant registers are according to the table below. (Default values for flow max corresponds to 15 m/s).

Analog in settings If using analog communication (4×071=1) you need to specify the operational voltage range and also corresponding max and min values; 1. Configure register 4×500 for analog in level configuration ( (0) 0-10V, (1) 10-0V, (2) 2-10V, (3) 10-2V) if you are using analog control of the set points. (If set points are controlled via bus this point can be ignored) 2. Configure registers 4×501–504 with relevant data for max and min levels for the voltage range selected in previous step. Register 4×501–502 are used if the device is controlled with angle (4×070=1) and registers 4×503–504 are used if the devi- ce is controlled using flow (4×070=2). If set points are controlled via bus this point can be ignored. Default values for the relevant registers are according to the table below. (Default values for flow max corresponds to 7 m/s).

PLEASE LOOK IN THE APPENDED MODBUS REGISTER FOR INSTRUCTIONS ON HOW TO CHANGE REGISTER VALUES. SOME VALUES HAS SCALE FACTORS AND SOME VALUES OCCUPY TWO REGISTERS! Settings for override The controller has two different override functions that can be initiated either over the bus or with analog input (only in case of input voltage range of 2-10 V or 10-2 V). If controlled via bus (register 4x071 = 0), then the damper can be forced (register 4x151) to fully open or fully closed position, or the flow rate setpoint can be set to minimum or maximum flow rate setpoint (according to registers 4x315 and 4x316, respectively). If the unit is controlled with analog input (4x071 = 1), then the damper can be forced to fully closed position (regardless the settings in register 4x501, which represents the mini- mum angle (fully closed) of the damper in normal mode). Override function by bus: 1. Normal mode, no override (register 4x151 = 0). 2. Go to maximum flow rate setpoint (register 4x151 = 1). 3. Go to minimum flow rate setpoint (register 4x151 = 2). 4. Go to fully open damper position (register 4x151 = 3). 5. Go to fully closed damper position (register 4x151 = 4). If an override is initiated, it can be restored either manually by setting register 4x151 to 0, or automatically after the prede- fined override timeout in register 4x150. Analog override function: In analog mode (4x071 = 1), the override function can only be called if input voltage range is set to 2-10 V or 10-2 V (4x500 = 2 or 3, respectively) and the controlled variable is flow rate (4x070 = 2). If these settings are active, the override function is set as follows: 1. Normal mode, no override (input voltage ≥ 2 V). 2. Go to fully closed damper position (if input voltage is lower than the value defined in register 4x511).

des us in everything we do. We have made it our mission to create a healthy indoor climate – and to simplify the construction of sustainable buil- dings. We do that by designing innovative pro- ducts and solutions that are easy to use, as well as offering efficient availability and logistics. We are also working on ways to reduce our impact on our environment and climate. We do that by de- veloping methods to produce our solutions using a minimum of energy and natural resources, and by reducing negative effects on the environment. We use steel in our products. It’s one of few materi- als that can be recycled an infinite number of times without losing any of its properties. That means less carbon emissions in nature and less energy wasted. We simplify construction 2018-12-06
