Check that you have inserted the fiber into the LID-System.If the error persists, select Manual fiber adjustment from the menu and make sure that a minimum level of 1.0 is dis-played for uninterrupted fiber.Clean the LID-System (see Cleaning the LID-System on page 6-21). If the LID level is still not high enough with a continuous fiber, the fiber is not LID-compatible.In this case remove the color (coating) from the length of fiber inserted into the LID. If the problem still persists, the fusion splicer will have to be returned to the service center. However, you can continue working with the video system.

The fiber buckles at the start of the fusion proc-ess. When the stand-ard or the precise fusion process is used, a more or less usable splice is obtained after a long fusion time. If a fixed fusion time is used, excessive splice losses result.

Pre-fusion time is too short or pre-fusion current too low.

Service center.In most cases you can still rescue unsuccessful splices by re-fusing the splice (see Re-Fusing on page 4-8).Set minimum fusion time to 1.5 s in order to avoid this error.

Autofeed may be set too high as well.

No AC power.

Defective power supply.The fusion operation is usually aborted after 1s for the standard and the precise fusion processes bad splice, high splice loss.The fiber demonstrates irregularities at the fusion point when dis-played at the monitor. The splice breaks easily when removed.Good results can be achieved with fuse again.

The minimum fusion time is too short. Automatic fusion time control interrupts fusion before an homogenous joint is com-pleted.
