Splicing mode and program selection

Select splicing mode

1

Though the splicer is saying in the

message field

to “PRESS

FUSE BUTTON,” you should make sure the correct splicing
mode and program are selected.

As mentioned earlier, the default splicing mode is Automode,
and this will be the mode the splicer is in when you just turn it
on. In Automode, the splicer automatically carries out fiber
alignment and initiates fusion. However, if you want to manu-
ally align the fibers and initialize splicing, you can change to
Manual mode by pushing the MODE button. The

mode field

will then read to “FSU 995 FA MANUAL MODE.” To change
back to Automode, just push MODE again. Remember that
you can always check which mode you are in during splicer
preparation by reading what is displayed in the

mode field

.

In this section on Basic Operation, we are only going to use
the pre-defined programs (Programs 01-10) as examples, but
you would follow the same selection procedure if you wanted
to load in one of your own programs created through the
instructions outlined in the section on Advanced Operation.

A

The first step is to press the ENTER button. At this point

both the

mode

and the

message field

will change. The

mode

field

will display the current splicing program, and the

mes-

sage field

will ask you if you want to change it. For the pur-

poses of demonstration, we are going to assume that the
current splicing program is program 01, NORMAL SM +SM.

B

If you press Yes , the message field will then be open for

you to enter a new program.

If you press No , you will jump to step F.

Enter

To see a list over the pre-defined programs (Programs 01-
10), you can either look on page 16 of this manual, or
follow the instruction in optional step BB on the next page
as to how you can access the screen-viewer.
