Lindab FTMU UltraLink Monitor Instruction Manual

Lindab FTMU UltraLink Monitor

Lindab FTMU is a highly accurate measurement device that measures air flow and temperature in ventilation systems. It is designed to provide reliable data to HVAC engineers, building managers, and maintenance professionals. The device is equippedVwith two flow sensors that are mounted on the sensor body and connected to a display unit. The display unit is mounted on top of a shelf on the sensor body. The FTMU can communicate via analog or digital signal using Modbus.

Technical Specifications

• Measurement range: 0-10 m/s
• Accuracy: ±3% of reading + 0.1 m/s
• Temperature range: -20°C to +80°C
• Power supply: 24V DC
• IP classification: IP54

Mounting Instructions

It is important to follow the mounting instructions to ensure accurate measurements. The device should be installed in a straight duct, and the longer the distance to disturbance, the higher the measurement accuracy will be. The first flow sensor should not be placed on an outer radius of a fitting. Other obstructions in the duct system such as axial fans, silencer baffles, or cleaning hatches are not allowed before the UltraLink (in the direction of the flow). If a cleaning hatch is required, it must be placed after the UltraLink (in the direction of the flow).
It is also important to note that the flow sensors are placed at a fixed distance to each other and should never be removed or used as handles when turning the sensor body. Never install a measurement unit after (in airflow direction) two disturbance fittings where those two fittings are installed in two different levels and the airflow also turns in cross direction. Not following these rules may cause damage and result in inaccurate measurements.

Usage Instructions

• To use the FTMU, first, ensure that it is properly installed in a straight duct according to the mounting instructions. Then, connect the device to a power supply of 24V DC. The FTMU can communicate via analog or digital signal using Modbus, so ensure that the appropriate communication method is used for your system. The display unit provides information on airflow direction, status light, display parameters, CE mark, and IP classification.
• If non-optimal installation situations appear, or several successive disturbance faults exist, please contact Lindab sales for consulting.
• Lindab reserves the right to make changes without prior notice.

Introduction

UltraLink® FTMU is a highly accurate flow monitor without any obstacles in the airstream that creates pressure drop. It mea-sures 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 minimum flows. The low flows are a pro-blem since they are very difficult to measure, which makes it difficult to control the ventilation system.
The new technology of UltraLink® makes it possible to measure lower air flows compared to today’s products while maintai-ning measurement accuracy. This offers great advantages for the user in terms of comfort and savings in energy consump-tion, which is of great interest.

Overview

Application
The FTMU is suitable for measuring air flow and tempe-rature. Communication is established via analog or digital signal using Modbus.

Design

• The FTMU consists of a sensor body with Lindab Safe gaskets.
• 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 sensor body.
  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.

Mounting

Planning

• The longer distance to disturbance, i.e. the longer straight duct before the FTMU, 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 FTMU and hence the positioning of the first flow sensor has an impact on the uncertainty of the measurement. It is not recommended to mount the FTMU so that the first flow sensor (*) is placed on an outer radius of a fitting.

• For example: in the case of the bend in the table below, by rotating the FTMU to position the first flow sensor according to the first picture (with the first flow sensor on the inner radius of the bend), the FTMU can be placed at the distance
  of two duct diameters from the disturbance to achieve 5 % uncertainty. Positioning the FTMU according to the second picture (with the first sensor on the outer radius of the bend), the FTMU must be mounted five duct diameters from the disturbance to achieve the same level of uncertainty.

• Other obstructions in the duct system such as axial fans, silencer baffels or cleaning hatches etc. are not allowed before the UltraLink (in the direction of the flow). If a cleaning hatch is required, it must be placed after the UltraLink (in the direc-tion of the flow). The reason is that these cause turbulences, which can result in errors in flow measurements.

Electrical installation

Please note:

• You must under no circumstances make any holes or connect anything with screws to the body of the FTMU.
• In case electrical installation equipment such as a junction box is needed for installation, the FTES is a Lindab accessory which can be mounted on the FTMU without causing damage to the FTMU.
• Never remove the blue electronics box.
• Never remove the transducers.

For cable connections there is two options, use the premounted cable or connect directly in the
PCB (option A and B):

Option A

Use the premounted cabl e >>

•     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 pos- sible for optimal Modbus communication.

Option B

Connect directly on PC B >>

•     To access the terminals on the circuit board, remove the lid by pushing the two heels on the side of the blue box.
•     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 must 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: Connect to premounted cable

• Connect the premounted cable in a junction box near the FTMU. 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 FTMU as possible, then cut the premounted where it is as short as possible for installation.

Option B: Circuit board screw 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.

• 24V, power supply (AC G, DC +) *
• . GND, power supply (AC G0, DC -) *
• +B, connection for Modbus via RS485
• -A, connection for Modbus via RS485
• SH, shield
• GND, ground (system neutral)
• AO1, analog output
• AO2, analog output
• AIN, (not used in this version)
• MO1, (not used in this version)
• MO2, (not used in this version)
• GND, ground (system neutral)
• SCL, not used
• SDA, not used
• GND, ground (system neutral)
• 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

cable)

Using other cables for Modbus signals may result in communication problems.

Analog connection

When connecting the FTMU using analog signals, it is impor-tant to connect the analog out signals on the FTMU (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.

Digital connection (Modbus)

Connect A on the RTU to -A on the display unit and B to +B. When connecting more than one FTMU 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 the ground at the transformer from which its power is supplied .
| | | | | |
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 an 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 existence 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 resistor from -A to GND and one from +B to the 3V3 terminal. It is also recommended to 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.

Power supply

Transformer sizing
The needed size of 24 V AC transformer(s) can be defined by adding up the dimensioning power consumption [VA] of all the components. 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 presuppo- ses 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 ® FTMU is 0,5 VA.

It is not recommended to use a transformer with a higher capacity than 150 VA.

Commissioning

Mobile app

Using a smartphone with the Lindab OneLink app, nearby UltraLinks will be identified. Now you can connect to all the different UltraLink units, change settings and view information regarding each unit. You can find the OneLink 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.

Lindab Ultra BT™ Room Control System

(Installation of wireless sensors)
Ultra BT is based on few components and introduces a revolutionized way of controlling and optimizing your Demand Controlled Ventilation system at room level.
It is a 360-degree system upgrade with a fully integrated Bluetooth Technology, making both costs, installation complexity, and daily operations much more efficient and indoor climate optimal at all times.

Lindab Ultra BT™ User Manual

You can find the specific user manual for the Ultra BT™ Room Control System by clicking or scaning the QR code.

Display

The display can show useful information both with the diode flashing in green (status light) and with parameters in the 225757 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 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 1

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;

• Air flow (m³/h)
• Air flow (l/s)
• Air velocity (m/s)
• Temperature (°C)
• FTMU ID number

Status light

The green status light indicates

The Blue status light indicates:

ID-numbers

• The FTMU is given an  ID-number between 1 to 239 Serial no. 132600052 during production. The given Lindab® UltraLink ID-number can be seen on  the label on the outside of the box the FTMU 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 table below) or with the OneLink app. The register for Modbus ID is a holding register with address 4×001.
• Correcting flow measurement for installation close to disturbance Later UltraLinks have a function to compensate for mounting 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 UltraLink close to a disturbance, the correction is done via a function in the OneLink 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.

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 below table.
• connecting a PC via Modbus and using the “Configuration Tool” software.
• connect a Bluetooth device and use the OneLink application.

Maintenance
The FTMU does not normally require any maintenance. The visible parts of the device can be wiped with a damp cloth.

Configuration menu structure
The configuration menu is activated by long pressing the button (5 sec). After long pressing the button a new menu will appear with three different options;

• Con.Set (Connection settings)
• Cancel (Cancel and return to information menu)

Under Con.Set (connection settings) you can find the following options (toggle with short press, select with long press);

After that you short press to toggle to the desired number, then you long press to move the blinking cursor to the next single number in the current value. Proceed until the new value has been set and long press to continue.

Digital communication settings

Registers 4×001-4×009 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.
PLEASE LOOK IN THE APPENDED MODBUS REGIS-TER FOR INSTRUCTIONS ON HOW TO CHANGE REGISTER VALUES. SOME VALUES HAS SCALE FACTORS AND SOME VALUES OCCUPY TWO REGIS-TERS!
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 it can also be done via the OneLink app. For more register details see appendix.

Troubleshooting

We recommend you to in first hand use our Product Assistant inside the commissioning app OneLink.

1. Open Lindab OneLink app
2. Go to
3. Click on Product Assistant
4. Choose product

If digital communication fails, please verify the fol-lowing 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 OneLink 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 Confi-guration Tool and a biased RS485-USB converter.
• Keep the total length of stubbs (such as the premoun-ted cable) of a buss with 30 devices, no more than 20 meters.

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.

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.

Error codes
If a problem occurs the status light will start to flash and an error code will be displayed. Listed in the table below are their problem and possible solution.

•   something blocking the flow sensors

•   an electronic fault
