8. 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 and MicroFlow LOG 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
9. FIBER PROTECTION TECHNOLOGY
MicroFlow TOUCH and MicroFlow LOG 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 pre-set 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.
