Planning
The longer distance to disturbance, i.e. the longer straight
duct before the
UltraLink
®
, the higher the measurement accu-
racy will be. It is not recommended to mount the
UltraLink
®
so that the first flow sensor (* in the table on the next page) is
placed on an outer radius of a fitting. 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.
The sensor and the damper bodies can rotate relative to each
other. This means that the sensors can be optimally posi-
tioned independently of the desired position of the display
and damper body. View table on next page for directions on
how to position the sensor body for optimal performance.
Mounting
Position the Controller 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. Make
sure the airflow arrow is pointing in the direction of the
airflow. Note the ID-number of the monitor. The ID can be
found on the label of the box the monitor was delivered in or
on the label on the monitor and are the three last numbers
of the serial number.
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 Controller
since they may break and changes in their positions might
influence the measurement accuracy. When the sensor
body is positioned accurately for FTCU of dimension 100—
315 it should be connected with screws to the damper body
in the same way as when you connect ducts and fittings.
FTCU of dimension 400—630 has a flange which needs
to be loosened in order to rotate the sensor and damper
bodies relative to each other. The flange needs to be
tightneded once the bodies are placed correctly.
The Controller can be connected to a RTU (remote termi-
nal unit) via analog or RS485 communication (Modbus). To
be able to connect cords to the terminal board the rubber
cable grommet on the back 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. 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.
