Instruction for ELTEX UPG
Yarn break detector
16720-16730
Green LED
General
The UPG is a small, general-purpose yarn break detector in a
robust metal housing. It works on the piezoelectric principle,
detecting the yarn movement.
The ceramic sensor part can be used as a closed eyelet or as
an open bar.
The yarn motion is detected most effectively when the yarn
deviates about 10–15° as it passes through the sensor.
When the UPG detects yarn movement, the green LED (light
emitting diode) is on
Fitting
The UPG yarn break detector is fitted on the machine
with two screws, maximum diameter 3 mm.
NOTE!
Electrical interference caused by insufficient
machine ground can cause the UPG to indicate yarn
movement when no yarn is moving.
This can be corrected by electrically insulating the
UPG from the machine frame. Two nylon screws and
an insulation pad can be used to achieve this.
These parts are included with the UPG sensor.
These parts can also be ordered from Eltex.
The part numbers are:
#4144 Nylon Screw,
#6868 Insulation pad
Adjustment
If the factory setting of the sensitivity is not suitable, it
can be adjusted with the potentiometer, located
under the lid.
When making adjustments, use a small screw-driver,
maximum size of 2.5 mm.
Minimum setting ( counter clockwise) is for
course, fast moving and/or high-tension yarn.
Maximum setting ( clockwise) is for fine, slow
moving, and low-tension yarn.
