Maintenance
7.1. Fiber Holding Block Maintenance
The fiber holding blocks must be cleaned
periodically to ensure accurate fiber positioning. It is
also sometimes necessary to change fiber holding
block inserts to accommodate different fiber sizes.
7.1.1. Changing the Fiber Holding Block
Inserts
As discussed in Section 3.5.4, the lower insert in
each of the LFS4100 fiber holding blocks is a
special transfer insert designed to speed up fiber
transport and positioning. This insert is normally
held in place with magnets instead of setscrews.
While there are three setscrews that can be used to
clamp the transfer insert in place, they are not
necessary for the system to function properly. If
these setscrews are not used, the transfer insert
can be quickly dropped in place after use in another compatible Vytran system.
However, the top insert
is
held in place with setscrews. These two set screws are located in the back of the lid
and must be loosened before the top insert can be replaced.
7.1.2. Cleaning the Fiber Holding Block Inserts
Debris in the fiber holding block V-grooves may interfere with fiber positioning. The V-grooves should be cleaned
carefully using a soft brush moistened with acetone.
7.1.3. Adjusting the Transfer Insert Clamp
The clamp at the end of the transfer insert can be adjusted to accommodate fibers of slightly different diameter.
To do this, the user must first loosen the two setscrews in the back of the clamp and then adjust the setscrew in
the bottom of the clamp. If the transfer insert is to be used with a smaller fiber, the user should turn the screw
clockwise. If the transfer insert is to be used with a larger fiber, the user should turn the screw counter-clockwise.
The side of the clamp should remain flush with the end of the insert. Once the correct block height has been
reached, the two setscrews in the back of the clamp should be re-tightened.
