6. Troubleshooting
The electrodes typically need replacement after 3000 splices . Some common
symptoms that indicate the electrodes need replacing are:
٠ High or inconsistent splice losses
٠ Bubbles in the fibers after splicing
٠ Diameter faults
٠ Fluttering or unstable arc observed on the monitor
٠ Fiber burned in half
٠ Sizzling noise while arcing
Refer to page 3-6, “Electrode replacement procedures”.
If an electrode tip touches something, it will be deformed, causing poor arcing
problems. Take care of the handling of electrodes.
Fiber breaking
When the splicing process is complete, a proof test may be performed on the fibers
while in the fiber chucks. If the fibers are breaking when the proof test is performed,
re-do an arc test. If the arc power level is too weak, the splice may be poor, resulting in
fiber breaking.
If the fibers are breaking in spite of a good arc test result, clean the V-grooves and the
bare fiber pads completely. Deterioration of a jacket remover/fiber cleaver may lead to
fiber breaking. Clean the jacket remover/fiber cleaver completely.
Splicer does not power up
If the fusion splicer fails to turn on when the ON key is pressed, check the following:
٠ Verify that the battery pack is installed in the module bay properly
٠ Verify that the power plug is seated properly (the power cord is connected to the AC
adapter.)
٠ Verify that the LED of the AC adapter lights up.
٠ If using battery operation, ensure that the battery is fully charged.
If the splicer still does not power up after checking the above, contact our maintenance
service center.
