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.

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).
