Safety Instructions
Read and understand this operating
manual before operating the MicroFlow.
Follow all safety instructions. Failure to
follow the instructions may lead to
damage on the machine and mild to severe
personal injury.
Make sure to disconnect the machine from
the air compressor, before any kind of
adjustment and maintenance takes place.
The air pressure should never exceed the
recommendations from the suppliers of
microducts and fiber. The pressure may
never exceed 16 bar, which is the
maximum pressure for the MicroFlow
blowing machine.
WARNING: Exceeding max.
pressure may lead to machine
damage and mild to severe personal injury.
Observe that the machine is placed on a
stable foundation. Make sure that the fiber
and duct are placed correctly in the
machine.
Make sure you do not touch the fiber too
close to the machine because you risk
getting your fingers injured, and make sure
the fiber does not make loops that might
be dangerous to persons around the
machine.
Never wear loose clothing
WARNING: Loose clothing may
become entangled in the machine.
Use hearing protection, if the air
compressor is placed nearby.
The operator must make sure that no
other persons are close to the machine and
cable drums in a way that could be
dangerous when the machine is started.
It is always a clear advantage to be well
prepared so that you can run the blowing
without interruptions. Pausing in the
middle of blowing creates a risk of being
unable to start again.
Make sure the working environment is
clean and tidy to avoid injuries due to
stumbling over fiber and equipment.
Maintenance
The MicroFlow does not require much
maintenance if the following recommendations
are followed:
Compressed air must be clean and dry. Use air
filter and water separator.
Clean the wheels on a regular basis, at least
once a day when the machine is in use.
Make sure the
sensor arms are
clean and can
move freely.
Check gaskets and rubber belts on wheels for
wear and tear on a daily basis, and replace if
necessary.
NB: Humid and polluted air may influence
machine life and performance and may result in
increased wear.
NB: Failure to maintain and clean the machine
may affect machine reliability.

Identification
These instructions have been made to support
the users of the fiber blowing machine
MicroFlow TOUCH. The machine type can be
identified by the type plate on the machine.
The type plate provides information about
serial number, year of production and name
and address of the manufacturer.
It is recommended to read this instruction
carefully and become familiar with the
functionality and maintenance of the fiber
blowing machine before use.
Application
The fiber blowing machine MicroFlow TOUCH is
constructed for blowing fiber optic cables with
a diameter of 0.8 to 5 mm into microducts with
an outer diameter of 5-16 mm.
We do not recommend use for other
applications.
Always use adaptor plates designed for the
actual diameter of cable and duct.
It is very important to use the correct adaptor
plates. If the adaptor plates do not fit the duct,
dangerous situations may occur.
The machine comes in a carrying case. When
the machine is not in use or during
transportation, always store it in the carrying
case.
Mounting and Preparations
Make sure to place the machine on a stable
foundation and to fasten it to withstand the
forces, which occur during use.
The adaptor plates in the machine must fit the
actual size of the fiber cable and the microduct
the cable is to be blown into.
The supply of fiber cable from a cable drum or
similar must be set up in a way where the fiber
cable is supplied to the machine evenly and
with the lowest force possible.
The microduct that the cable is blown into,
should be without sharp corners or bends.
Before blowing it is recommended to blow a
foam plug through the duct. This ensures that
the fiber cable can get all the way through the
duct without getting stuck.
Supply of Compressed Air and
Electricity
It is very important that the quality and volume
of compressed air for blowing is correct and
meets specifications. If there is water in the
compressed air or too low pressure and
volume of compressed air, it will create
insufficient results. The compressed air must
be filtered, cooled and dried to avoid moisture
and dirt in the microduct.
MicroFlow TOUCH uses 24V DC and can be
connected to 100-240V AC, 50/60 Hz with the
included transformer. The 100-240V AC power
supply must be stable and at least 2A.

Fiber Protection Technology
MicroFlow TOUCH has a unique protection
technology securing that there is no damage to
the fiber cable. The protection technology
stops the machine if the fiber cable meets an
obstacle.
The stop occurs because the cable gets bent
inside the fiber blowing machine as the fiber
cable meets an obstacle. This is registered by a
sensor, and the motor stops immediately.
The machine will also stop automatically if the
motor exceeds the preset maximum torque
level (see section about Torque Off-Set for the
minimum effect needed depending on the
speed).
In both cases of protection the machine stops
immediately so the fiber cable does not get
damaged.
Fault Sequence
When the protection technology is activated, the machine starts the following fault sequence:
The motor stops immediately.
Short break.
The machine pulls the fiber slightly backwards until the fiber is straight in the blowing junction
block.
The motor starts and accelerates to the preset maximum speed.
If the protection technology is activated 3 times, the machine will come to a full stop, and an
error message is shown in the display.

Running the Fiber Blowing Machine
Prepare the fiber cable and place it inside
the fiber blowing machine. Adjust the drive
wheels until they are tight around the fiber
cable
Place the microduct, which the fiber cable is
to be blown into, in the blowing junction
block
Close the lid and tighten the screws on top
On the TOUCH screen:
Set the desired speed (m/min)
Set the torque level to the desired
maximum
OPTIONAL: The preset meter counter can
be used to stop the machine after a
given distance (set to “0” and the
machine will continue indefinitely)
Press the ON/OFF button, and the machine
will accelerate to the preset maximum
speed
After 10-20 meters, turn on air. Gradually
increase air supply as the blowing is
proceeding.
The blowing is now running automatically
If the machine stops unintentionally, there
are two adjustable parameters:
increase air supply
or reduce speed if there is no more air
pressure
Stop the machine, either manually or when
reaching the preset distance
Turn off air
The lid can be opened when the air pressure
gauge is at “0” bar/psi
WARNING: Do not open the
machine while under pressure, as
this may damage the machine and
cause personal injury.

Use of Control Unit
The control unit is used for operating the fiber blowing machine as well as adjusting the different
parameters, for instance speed and torque level.
Adjustable Parameters
ADJUST
Torque Level
To avoid overload of the fiber cable, it is possible to adjust the maximum torque
level. If this maximum torque level is exceeded during blowing, the protection
technology stops the machine so that the fiber cable does not get damaged. The
torque level can be adjusted from 10 to 100% of the motor’s maximum effect.
ADJUST
Counter
Here you can choose a distance that the cable should be blown. When the pre-set
distance has been reached, the machine will stop automatically. If the counter is set
at “0”, the machine will continue indefinitely.
ADJUST
Speed
Here the speed of the machine can be adjusted in meter per minute.
ADJUST
Acceleration Ramp
Adjusts the acceleration when the machine starts. It can be adjusted between 5 and
100, with 100 being the fastest acceleration. Recommend value: 5
ADJUST
Deceleration Ramp
Adjusts the deceleration when the machine stops. It can be adjusted between 5 and
100, with 100 being the fastest deceleration. Recommend value: 100
