Maintenance And Adjustment - Televes 232301 Manual De Usuario

Procedure, in case of cut problems
If you can not cut the fiber, check:
1.
Both fiber protections (900 and 250 microns) are correctly removed
by the peeler.
2.
The blade is not worn or marked (you can control the cuts number,
based on the melting counter present in your fusion splicer).
3. The height of the blade is correct (the blade must protrude minimally
on the fiber supporting rubbers).
If the fiber is chipped in the cutting process, check:
The blade height. If it protrudes too much on the fiber supporting
rubbers, it will cause the commented anomaly. To control that the height
is not excessive, it can support an element that forms a straight line
between both rubbers. The correct height of the blade will be that which
grazes this element, this being supported on the rubber.
If the cut has an excessive angle, check:
The fiber deposited on the cutter does not form an angle on the support
rubber. This can generate fusion problems (greater cutting angle). The
fiber must be deposited on both rubbers forming a straight line between
them. The attached example is a sample of how the fiber should NOT be
deposited.
To correct this, rotate the fiber on itself until the natural curve of the fiber
is down, and therefore the fiber maintains a straight line between both
rubbers:
Right finish
Wrongly positioned fiber
Deformed blade
Blade too high

Maintenance and adjustment

1. Fiber optic cleaver maintenance.
To maintain an excellent quality of cut cleaning, it is advisable to clean
(regularly with a cotton swab moistened in isopropyl alcohol):
- The edge of the cutting blade.
- The 4 rubber pads located on the blade sides.
- Different support guides for fiber.
2. Adjusting the height of the blade.
Using a flat-blade screwdriver (select the proper thickness, avoiding the
damage the cover), act on screw number 2.
Turning the screw to the left will lower the blade. Turning the screw to
the right will raise the blade.
Observe the following guidelines:
Insufficient blade height will cause no cutting.
An excessive height of the blade, will generate a cut chipping or absen-
ce of cutting.
A wear of the blade, will generate absence of cut, bad cut or breakage
of the fiber.
To control the height of the blade, you can use an external element for
reference. The blade must touch the outer element, without causing it
to separate from the support rubber.
If the position of the blade (1-16) changes, its height must be readjusted.
3. Blade position adjust
The fiber optic cleaver has a blade with 16 positions. Each position allows
to make 1000 cuts as minimum value, representing a total of 16000 cuts
per blade as minimum value.
While the Fiber optic cleaver is performing its function correctly, do not
vary the position of the blade, even though it exceeds 1000 cuts. You only
have to change the position of the blade, if after checking that the blade
height is good, the cutting is not correct, or it does not execute.
