Take the following steps to start the function of automatic splice:

1› Choose the function item of “FIBER”.

2› Make fiber facing.(see Chapter 6.2.4)

3› Open windshield and pressing plate to place fiber.

4› If you cover windshield, splicer will enter the interface of

“Pressing button, continue”, then press“RUN”button. Splicer will

get into an automatic process: cleaning fiber, checking facings, setting

gap, rectifying fiber core, discharging splice and estimating the loss of splicing point. Finally it will show the

estimated value of the loss on screen. If the screen shows such information as “Left-right fiber facing is not good”

or “Replace fiber”, splicer will stop working. Please refer to Chapter 6.2.4 or follow the instructions in Table 2 to

deal with this problem.

5› If the estimated value of splicing point loss is shown on the screen, please press the button “FUNC”. Then the

screen can shift the magnified images from X-axis to Y-axis.

Note:Note:Note:Note:

1> After pressing “RUN”, splicer is in automated continuous condition. Don’t press the button of “HEAT”,or it will lead to unusual mistakes.

2> Splicer can estimate loss only after automatic splice is carried out for one time.

3> The estimated loss has referential value only if electrode is in good condition, current is moderate,

discharging parameters are optimized and fiber attribute indexes are consistent.

4> Users are suggested to test discharge before splicing.

6.3.56.3.56.3.56.3.5 SpliceSpliceSpliceSplice corecorecorecore----liftliftliftlift fibersfibersfibersfibers

When users are splicing fibers, they may encounter such situations that splice loss is high or low. In this

case, users can deal with this problem by following such steps:

1> Check whether or not the electric arc is stable and parameters are appropriate.

2> If the electric arc is stable and parameters are appropriate, the problem may be fiber core-lift. The normal

solutions are to reduce the values of “ARC TIME” or “FORWARD”.

3> If the above-mentioned two measures do not take effect, users should mark direction angle on fiber to do

tentative splicing in order to get the best estimated value of splice loss.

6.3.66.3.66.3.66.3.6 AppraiseAppraiseAppraiseAppraise splicingsplicingsplicingsplicing qualityqualityqualityquality

Splicing quality can be judged by three aspects: the estimated value of splice loss, spliced shape and

splicing process. If we combine the three aspects together, we can give objective appraisal of splicing point.

1> If the splicing process is stable and the spliced shape is fine, as shown in Table 3, splicing effect is also

fine.

11

2> If the spliced shapes are in such conditions as shown in Table 4, fibers should be re-spliced even though

the estimated losses are low.

Because actual situations such as fiber, altitude, climate and electrode condition may have certain influence on

splice loss, KL-280 splicer provides the function of discharging test in order to get the lowest splice loss. The

concrete steps are as follows:

18

1〉 Press“MENU”to enter primary menu..2〉 Press“ ”or“ ”to make color frame point to the item of Working Mode.

3〉 Press“ ”or“ ”to choose the value “1”.

4〉 Press“ ”or“ ”to make color frame point to the item of “PROGRAM”

6〉 Press“ ”or“ ”to make color frame point to the item of “Splicing Process”

7〉 Press“ ”or“ ”to choose appropriate discharging process.

8〉 Press“ENT”to enter the menu of discharging process parameter.

9〉 Check whether or not splicing parameter is correct. (Discharging parameter is number 1-5.) If current

parameters are not correct, users can change them according to the following methods:

a> Press“ ”or“ ”to make color frame point to current parameters waiting to be changed.

b> Press“ ”or“ ”to increase or decrease current parameters

c> Users can press“ENT”to store discharging parameters after confirmation,d> Press“MENU”to exit menu one by one.

10〉Get two fibers waiting to be spliced and make fiber facings as good as possible.

11〉Open windshield and pressing plate.

12〉Put the two fiber facings into groove and close down windshield.

13〉In automatic operating condition, press “TEST” to carry out such functions as checking the quality of fiber

facing, setting gap, rectifying precision and discharging. Then splicer can automatically adjust discharging

current.

14〉If screen shows such information as “Strong current” or “Weak current”, users can copy steps 10>-13>

until it shows “Moderate current”. At this time splicer finishes discharging test and turns discharging

process to number 6.

Note:

1> Chosen fibers should be consistent with actual fibers. Users are suggested to test discharging before

splicing.

2> Discharging test can rectify not only discharging current but also the position of electric arc. So if gap

changes after test it is normal.

3> In the process of discharging test, screen shows such information as “Strong current”、“Weak current” or

“Moderate current”.

4> If screen does not show “Moderate current”, users can not enter the menu of discharging process

parameters in case of causing invalidity of the former test.

5> Moderate current has a certain scale. Users can choose appropriate current according to their demands.

6> Users must first of all check the quality of electrode because discharging test does not have referential

value if electrode is in bad condition.

7> The appointed “Splicing process” after discharging test can not ensure the best parameters because splicer

only takes “current” into consideration.

8> After pressing “TEST”, splicer is in the condition of discharging test. At this time don’t press “HEAT”, or

it may lead to mistakes.

8.48.48.48.4 OptimizeOptimizeOptimizeOptimize dischargingdischargingdischargingdischarging parameterparameterparameterparameter

The discharging processes (1-5) set by factory can satisfy all the present demands of splicing standard fiber.

However, in order to acquire the best splicing effects, it is necessary for users to optimize discharging parameters

on the basis of the set discharging processes.

8.4.18.4.18.4.18.4.1 OptimizeOptimizeOptimizeOptimize singlesinglesinglesingle modemodemodemode fiberfiberfiberfiber dischargingdischargingdischargingdischarging parametersparametersparametersparameters

To optimize discharging parameters, users should prepare instruments which can test fiber power loss, such as

lamp, dynamometer or OTDR. The optimization process is similar to the splicing process. Use instruments to test

splice loss and properly adjust discharging parameters until splice losses are consistent and minimized. The

general principles of optimizing discharging parameters are:

1> Strengthening current within a certain scale can acquire the effect similar to that of prolonging time.

2> The value of pre-splicing current cannot be larger than that of splicing current.

3> Users should not change the value of splicing push.

4> If needed, users should better choose current before changing the value of push velocity


1> Optimization of discharging parameters can take effect only if discharging electrode is in good condition.

2> Estimated loss shown on screen can have referential value only if discharging parameters are proper and

the physical parameters of two fibers are consistent.

8.4.28.4.28.4.28.4.2 OptimizeOptimizeOptimizeOptimize multimodemultimodemultimodemultimode fiberfiberfiberfiber dischargingdischargingdischargingdischarging parametersparametersparametersparameters

Optimization of multimode fiber discharging parameters is quietly different from that of single-mode fiber. The

choice of multimode fiber discharging parameters is not completely related with splice loss. As long as splicing

process is stable and fiber joint is smooth splice loss is normal. So it is not necessary to test splice loss.

The general principles of optimizing discharging parameters are:

1> The value of pre-splicing current cannot be larger than that of splicing current.

2> Pre-splicing time is always much longer than that of single-mode fiber.Possible problems and relevant measures are as follows:

1> Bubbles appear.

Solution: if not many, users can try to prolong pre-splicing time.

2> Not completely spliced and bright line breaks in the center of fiber.

Solution: prolong splicing time or strengthen splicing current.

3> Fiber joint is thin.

Solution: weaken pre-splicing current or reduce pre-splicing time.

Note: Because special discharging mode is applied to multimode fiber splicing process, it is normal if

splicing pictures shiver or it produces the sound of crackles.

after discharging. So the value of fiber shrinkage “ΔL” before and after splicing can be deduced from the

following formula:

ΔL＝(L3－L2)－(L1－L0)

Users can judge and rectify discharge current on the basis of ΔL.

The shrinkage value ΔL1 of left fiber can be deduced from the following formula:

ΔL1＝L2－L0The shrinkage value ΔL2 of right fiber can be deduced from the following formula:ΔL2＝L3－L1

Users can adjust gap position to conform to the changes of arc position.

L0 arc discharge L2

L1 L3

(ａ) (ｂ) (ｃ)

Note: discharge test can only change discharge current and other discharge parameters should also be optimized.

The power module possesses built-in lithium batteries: 11.1V/8.0AH.

(1) Check electric quantity of lithium batteries.

A． In close-down mode, press the button “PUSH” on power module. Then the four power indicators aligned on

the left turn red. They stand for high or low electric quantity. (See the following picture)

Electric quantity of lithium batteries (when press “PUSH” on power module)

B．In charging condition, the four power indicators aligned on the left stand for charging voltage, not electric

quantity of lithium batteries. (See the following picture)

33

(2) Charge lithium batteries

No matter whether or not electric quantity of lithium batteries is full, when users plug AC/DC adapters to power

module, it starts a charging process. Charging time is decided by electric quantity of lithium batteries. The longest

charging time is 3 hours and 40 minutes while the shortest charging time is 40 minutes. In charging process, indicator

(RED CHARGE) turns red. After charging it (GREEN FULL) turns green.

(3) Attentions:

A．Check electric quantity of lithium battery before splicing. If it is low, charge it at once.

B．Forbid putting lithium battery in hot environment or casting it in fire in case of explosion.

C．Don’t charge lithium battery in low-temperature environment in case of reducing its service life. Electric

quantity of lithium battery can reduce either in high-temperature or low-temperature environment.

D．Forbid dismantling power module.

E. Lithium battery is consumable. If all power indicators are bright but it is still of a very short service life,

change the battery. Users should choose the type of lithium battery appointed by our company.

F．If splicer can not be switched on or alarm bell rings due to under voltage, i.e. voltage is less than 10.5V,

charge lithium battery at once. (see the following picture)

1.Set gap.

If the vertical distance between two fibers is larger than a certain scale, screen shows “replace fiber” or “L/R

fiber facings not good” (see the following pictures)

2. Check and clean V groove

Core adjusting structure of KL-280 is very precise. Forbid pressing V groove heavily. Users should be

careful. Use alcohol sponge to wipe lightly along one direction. If dusts are still there, take it to a bright place

for careful observation. Use fiber head to clean it. In many cases, it is not dust that causes fiber deviation but

because fiber is not placed in groove effectively. Checking order: bending degree of fiber, flexibility of

pressing head. Finally, check if fiber spacing groove and V groove are in a straight line and if there is dust in

V groove.

3. If fiber still deviates after replacing, change working mode into manual and shift to corresponding picture.

Press “FUNC” to choose the interface of “L/R fiber drive”. Press to make two fibers aligned. Then change

working mode into manual. When users align one fiber with another, they must make the moving direction of

fiber consistent with the pointed direction.
