2020-08-05 UltraLink Controller FTCU lindab | we simplify construction 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.

Communication is established with analog or digital signals using Modbus. Design The FTCU consists of a sensor body attached to a damper body with Lindab Safe gaskets. The display unit and actuator are mounted on a cup to enable the FTCU to be insulated up to 50 mm. 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. Position- ing the sensor body correctly after a disturbance is crucial for the measurement accuracy, see page 4 for directions on how to mount the FTCU 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.

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 measurement. It is recommended to mount the FTCU so that the first flow sensor (*) is placed on the inner 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 FTCU can be placed at the distance of two duct diameter (Ød) from the disturbance to achieve the specified uncertainty. Positioning the sensor body according to the second pic- ture (with the first sensor on the outer radius of the bend), the FTCU must be mounted five duct diameters from the disturbance to achieve the same level of uncertainty. Please note: • Note the ID-number of the FTCU. The ID is the three last numbers of the serial number and can be found: - on the label of the box it was delivered in - on the label on the FTCU itself - in the display after pressing the “MODE” button - in the App when the product is on Controller FTCU Ø125 Serial no. 132600052 UltraLink Lindab®

Use the premounted cable >> • Connect power and communication cables to the premounted cable. • Check the label on cable for reference to cable colours. • It is important that the cable is as short as possi- ble for optimal Modbus communication. For cable connections there is two options, use the premounted cable or connect directly in the PCB (option A and B): Connect directly in the PCB >> • To access the terminals on the circuit board, remove the four Philips screws in the corners of the lid and remove the lid. • 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. Do not remove the blue box to do this! • When the cables have been connected they be strain relieved. The cables can be attached to the shelf by using cable ties that are attached around cut outs in the shelf. Option A Option B

Analog connection When connecting the FTCU using analog signals, it is important to connect the analog out signals on the FTCU (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. Option A: Connect to premounted cable Connect the premounted cable in a junction box near the FTCU. Con- nect power and signal cables in the junction box according to the color scheme on the lable on the premounted cable, see picture to the right. When connecting Modbus signal wires, the length of the premounted cable needs to be as short as possible, since these have a negative effect on signal quality. In this case, place junction box as close to the FTCU as possible, then cut the premounted where it is as short as possible for installation. Connection of UltraLink Note!

2020-08-05 UltraLink Controller FTCU lindab | we simplify construction Digital connection (Modbus) Connect A on the RTU to -A on the display unit and B to +B. When connecting more than one FTCU in series it is important to keep connecting -A to -A and +B to +B since crossing them will stop Modbus from working. It is recom- mended 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. When connecting signal ground, attach it to “GND” on the terminal to the right of the terminal for shield (SH) on the PCB. Then attach it to the corresponding terminal in the RTU. Connecting shield The shield in the RS485 cable should be connected to ground at the transformer and then continuously connect to ”SH” on all the UltraLinks 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. BA +B -A +B -A +B -A +B -A GND GND GND GND Signal ground Shield ground Biasing The master on the bus must have biasing on -A and +B. This is more or less standard on BMS-controllers, but if communication 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 communi- cation failure. Use 500 - 1000 Ω resistors and connect one resistor from -A to GND and one from +B to the 3V3 termi- nal. 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. 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.

The transformer power must exceed this. Use only safety isolating transformers. Calculation of the cur- rent demand I: I = (P1+P2+…+Pn) / U [A] where: Pn is the dimensioned power consumption for each component [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 neces- sary to use more transformers to prevent overheating. Supply cable sizing The wire size of the supply cable can be determined by calculating the resistance per meter R. The calculation presup- poses 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 transformer to a component [m] Wire cross section area as a function of resistance per m for copper wire 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. Power consumption The power consumption for dimensioning supply cables for an UltraLink® FTCU is 3-5 VA. See details on page 19. It is not recommended to use a transformer with a higher capacity than 150 VA.

2020-08-05 UltraLink Controller FTCU lindab | we simplify construction Commissioning Mobile app (recommended) If the UltraLink is equipped with Bluetooth (the Bluetooth logotype is printed on the display unit), wireless communication with the UltraLink can be established. Using a smartphone with the Lindab UltraLink app, nearby UltraLinks will be identified. Now you can connect to all the different UltraLink units to change settings and view information regarding each UltraLink. You can find the UltraLink app in both Google Play and AppStore, free of charge. The settings of all the different UltraLink units can then easy be changed directly through the app. This means you can have individually settings chosen for a specific building. It is therefore necessary to change the PIN code in the UltraLink, for a discription on how this is done, see page 13.

If the product is equipped with Bluetooth, then the diode will also flash in blue every three seconds. If a device has been con- nected to the UltraLink via Bluetooth, 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 14. 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 the air flow reading, temperature 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) • FTCU 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.

2020-08-05 UltraLink Controller FTCU lindab | we simplify construction Correcting flow measurement for installation close to disturbance Later UltraLinks have a function to compensate for mount- ing the product closer to a disturbance, and still have 5% measurement uncertainty, than what is specified in the chapter “Mounting”. If it is required to install an UltraL- ink close to a disturbance, the correction is done via a function in the UltraLink app. Connect a mobile device to the UltraLink and tap the “Device” tab, there is a function which is activated by choosing “Type of disturbance” and then “Distance to dirsturbance”. After these two inputs have been made, the function is active and corrects the flow according to the inputs made. Controller FTCU Ø125 Serial no. 132600052 UltraLink Lindab® ID-numbers The FTCU is given an ID-number between 1 to 239 during production. The given ID-number can be seen on the label on the outside of the box the FTCU is delivered in, the ID-number is the same as the three last digits in the serial number. If two or more Modbus devices have the same ID-number it is necessary to apply changes so that each of them get an unique ID-number to allow communication. To change the Modbus ID register of an UltraLink® all other devices with the same ID must be disconnected. It is more efficient to change the ID in the display under “Con.Set” (See page 14 for more info). The register for Modbus ID is a holding register with address 4x001. PIN code UltraLink with Bluetooth must be protected againt unau- thorized 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 deliv- ered 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 “Configura- tion Tool” software. • connect a Bluetooth device and use the “UltraLink” application. Maintenance The FTCU does not normally require any maintenance. The visible parts of the device can be wiped with a damp cloth. Settings for override The FTCU 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 minimum 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 predefined 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 over- ride 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).

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® Con- figuration tool (See separate documentation). For more register details see appendix. Digital communication settings Registers 4x001-4x009 are used to configure communica- tion 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. Control settings The FTCU 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 is analog or digital; 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 Modbus control of set points with “0” (0 = bus, 1 = analog). 3. During operation set points can be applied using regi- sters 4x302 (damper position) and 4×314 (flow) depen- ding 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).

2020-08-05 UltraLink Controller FTCU lindab | we simplify construction Analog communication settings Analog in settings via modbus 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 device is controlled using flow (4×070=2). If set points are controlled via bus this point can be ignored.

Error code Problem Comment Err001 Motor not working correctly Check motor cables and connections Err002 Angle sensor not working correctly Try to recalibrate using UltraLink® Configuration tool Err003 Flow set point not reached Check if the AHU supplying enough air Err004 Problems with flow measurement Might be caused by: • something blocking the flow sensors • an electronic fault • the flow sensors are not connected properly into the display unit • the sensor body is flawed Err032 Factory data is corrupted Reset to factory defaults using UltraLink® configuration tool Airflow IP42 Patented Status m³/h l/s m/s °C Mode Monitor FTMU Troubleshooting If digital communication fails, please verify the follow- ing before contacting support: • Check settings for Baud rate, parity and stop bit and make sure the master uses the same settings as the UltraLinks. This can be done with a mobile phone and the UltraLink app. • -A and +B are continuously connected between all the products without any mixups of -A and +B. • Bus layout is not allowed to be “star connection”. • The cables for power supply are connected identical on all products and transformers connecting G to G (24V) and G0 to G0 (GND). • The shield is continuous along the bus and grounded only at the transformer and the last UltraLink on the bus. • There are not more than 30 devices on the bus. (Install a repeater if you have more than 30 devices.) • The total length of the bus is maximum 300 m. (Install with a repeater if you have more than 300 m bus cable.) • Try to establish communication with a PC using Con- figuration Tool and a biased RS485-USB converter. • Keep the total length of stubbs (such as the pre- mounted cable) of a buss with 30 devices, no more than 20 meters. If analog signals fails, make sure to doublecheck the following: • Measure voltage on the screw terminal, the voltage should be the same as that on the BMS controller. • If the voltage is not correct, check that the wire is firmly attach to the terminal of the UltraLink. If it is not, then the UltraLink might not be able to pick up the signal. Problems accessing UltraLink via Bluetooth: • The UltraLink must have the Bluetooth logotype on the lid of the display unit in order to have a Bluetooth function. • To access the UltraLink via Bluetooth, the correct PIN code must be input before being able to connect. Verify with administrator that the PIN code is correct if you cannot connect.

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
