TEMPO 920CL Optical Fiber Cleaver Instruction Manual

TEMPO 920CL Optical Fiber Cleaver

Product Information

intended to precisely cleave fiber optic cables.

Product Usage Instructions

1. Open the fiber dust bin.
2. Open the cleaving handle mechanism.
3. Insert prepared fiber into the fiber clamp at the desired cleave length.
4. Close the fiber clamp.
5. Close the cleaving handle mechanism down.
6. Push the cleaving wheel backward to cleave the fiber.
7. Open the cleaving handle mechanism.
8. Open the fiber clamp.
9. Make sure that the cut fiber is safely in the dust bin.

Blade Position Change

1. Loosen the blade locking screw.
2. Rotate the blade to the next scale position.

Normal Use and Maintenance

• Make sure that the rubber presser feet and the fiber guide groove are clean (no dust and fiber debris).
• Keep the fiber contact surfaces clean by using isopropyl alcohol with a lint-free cleaning wand.
• Change the position of the cleaving wheel if the cleaving quality degrades due to the blade being worn (usually 1000 cleaves per blade position).
• After the cleaving wheel has been rotated through all 16 positions, the height can be increased and the wheel can be reused through all of the 16 positions once again.
• The cleaving wheel can be rotated two times for a total of 48,000 cleaves.

Blade Replacement

1. Lay down the cleaver with scale numbers on the blade facing up.
2. Remove the blade locking screw.
3. Remove the old blade and replace it with a new blade. Do not touch the blade (very sharp!). Use tweezers to remove the old blade and insert the new blade.

Important Safety Information

Warning:

• Read and understand all of the instructions and safety information in this manual before operating or servicing this tool.Failure to observe this warning could result in severe injury or death.
• Electric shock hazard: Contact with live circuits could result in severe injury or death.
• Wear eye protection when using this tool. Fiber fragments can be extremely dangerous if they come into contact with eyes or skin or are ingested.

Caution:

• Collect all fiber scraps in the dust bin and dispose of them in an approved fiber disposal unit.
• Do not touch the cleaving wheel blade cutting area.
• Do not disassemble or lubricate. Contact Tempo Communications for maintenance and repairs.
• Store in a dry, clean location in the protective container.
• Store the 920CL with the two foam chips to stabilize the cleaving mechanism from moving.

Failure to observe these precautions may result in injury and may damage the unit.

Operation

1. Open the fiber dust bin.
2. Open cleaving handle mechanism.
3. Insert prepared fiber into the fiber clamp at the desired cleave length.
4. Close fiber clamp.
5. Close the cleaving handle mechanism down.
6. Push the cleaving wheel backward to cleave the fiber.
7. Open the cleaving handle mechanism.
8. Open fiber clamp.
9. Make sure that the cut fiber is safely in the dust bin.

Hint:
It is easier to load the fiber into the adapter if the fiber is curled in a downward direction from the fiber clamp.

Normal Use and Maintenance

Make sure that the rubber presser feet and the fiber guide groove are clean (no dust and fiber debris). Keep the fiber contact surfaces clean by using isopropyl alcohol with a lint free cleaning wand.

Change the position of the cleaving wheel if the cleaving quality degrades due to the blade being worn (usually 1000 cleaves per blade position). After the cleaving wheel has been rotated through all 16 positions, the height can be increased and the wheel can be reused through all of the 16 positions once again. The cleaving wheel can be rotated two times for a total of 48,000 cleaves.

Blade Position Change

1. Loosen blade locking screw.
2. Rotate blade to next scale position.
3. Lay 0.7 mm pencil lead across both pressure pads.
4. Move the slider back and forth and check if the blade touches the pencil lead.
   • If the blade touches the pencil lead: Perform a cleave and check cleave angle on the 915 fusion splicer.
   • If cleave is not good: Check if the blade is damaged or dirty at the new position.
   • If the blade drags pencil lead all the way across:
   • If the blade does not touch the pencil lead: Rotate the pencil lead ≈180° and try again.
   • If not sure: Perform a cleave and check cleave angle on the 915 fusion splicer.
   • If cleave is not good: Go to “Blade Height Adjustment”.

Blade Replacement

1. Lay down cleaver with scale numbers on blade facing up.
2. Remove blade locking screw.
3. Remove old blade and replace with new blade. Do not touch blade (very sharp!) Use tweezers to remove old blade and insert new blade.
4. Lock new blade at position “1”.
5. Lay 0.7 mm pencil lead across both pressure pads.
6. Move the slider back and forth and check if the blade touches the pencil lead.
   • If the blade touches the pencil lead: Perform a cleave and check cleave angle on the 915 fusion splicer.
   • If cleave is not good: Check if the blade is damaged or dirty at position “1”.
   • If the blade drags the pencil lead all the way across  Go to “Blade Height Adjustment”.
   • If the blade does not touch the pencil lead: Rotate the pencil lead ≈180° and try again.
   • If not sure: Perform a cleave and check cleave angle on the 915 fusion splicer.
   • If cleave is not good: Go to “Blade Height Adjustment”.

Blade Height Adjustment

1. Loosen both compression screws and height locking screw.
   • Height adjustment screw
   • Height locking screw
   • Compression screws for blade height adjustment arm
2. Turn height adjustment screw:
   • CW if blade did not touch pencil lead (moves blade up).
   • CCW if blade dragged pencil lead across (moves blade down).
3. Tighten height locking screw and both compression screws.
4. Lay 0.7 mm pencil lead across both pressure pads.
5. Move the slider back and forth and check if the blade touches the pencil lead.
   • If the blade touches the pencil lead: Perform a cleave and check cleave angle on the 915 fusion splice.
   • If cleave is not good: Check if the blade is damaged at its current position.
   • If the blade drags the pencil lead all the way across  Go back to step 1 and adjust CCW until good.
   • If the blade does not touch the pencil lead: Rotate the pencil lead ≈180° and try again.
   • If not sure: Perform a cleave and check cleave angle on the 915 fusion splicer.
   • If cleave is not good: Go back to step 1 and adjust CW until good.

Specifications

Troubleshooting

2.    Fiber surface not clean.

3.    Clean rubber presser feet.

4.    Increase the height of the cleaving wheel.

The end face has a lip.| 1.    Increase the height of the cleaving wheel.

2.    Clean rubber feet.

3.    Check rubber feet for wear or abrasion.

The end face has a shadow or incline angle.| Increase the height of the cleaving wheel.
Core missing.| Lower the height of the cleaving wheel.

• Lip
• Incline
