Do not excessively bend or kink fiber optic cables. (min. bending radius 25 mm).
Repairing
Special tools, testers and auxiliary items required
• Fiber Optic Plier Repair Set (VAS 6223)
• Air Hose Pliers (VAS 6228)
Checking Remaining Cut Indicator
- Start by checking the remaining cut indicator:
• The (VAS 6223/1) cutting device can perform approximately 1260 cuts. The blade is rotated for each further cut.
• The last remaining 150 cuts are indicated via the remaining cut display - arrow -.
• Once no further cuts are available, the blade is blocked. It must then be replaced, refer to the instructions for the (VAS 6223/1).
Preparing (VAS 6223/1)
- Release transport safety device on cutter by loosening the hex socket bolt - arrow -.
Fiber Optic Cable, Cutting to Length
- Establish length of fiber optic cable required.
- Open (VAS 6223/1) and insert the fiber optic cable - 1 - into the trimming station.
- Close cutting tool to cut fiber optic cable to length.
Stripping
- Open (VAS 6223/1).
• Stripping lever must be located in the lower position - arrow -.
- Insert fiber optic cable - 1 - into stripping station.
• Fiber optic cable must terminate flush to rear side of cutting pliers.
- Close (VAS 6223/1) until stop and keep closed.
- Pivot stripping lever upward - arrow -.
- Open cutting pliers and remove fiber optic cable - 1 -.
- Detach separated section of insulation from fiber optic cable.
Precision Cutting (Production of Optical End Face)
- Slide fiber optic cable - 1 - into cutting station.
• Insulation must make contact at stop - arrow - of cutting station.
- Close (VAS 6223/1).
- Press down - arrow - cutting device.
- Open (VAS 6223/1) and remove fiber optic cable - 1 -.
• Fiber optic cable is only to be placed on an absolutely clean surface.
Activating Transportation Safeguard
- Close (VAS 6223/1).
- Tighten hex socket bolt - arrow - for transport safety device on cutter.
Attaching Brass Pin Contact to Fiber Optic Cable
- Open securing lever on (VAS 6223/2) - arrow 1 - and - arrow 2 -.
- Insert a brass pin contact - 1 - into mount.
- Close securing lever on (VAS 6223/2) - arrow -.
- Slide fiber optic cable - 2 - in brass pin contact - 1 - up to spring loaded stop.
- Slide fiber optic cable further in up to fixed stop and close (VAS 6223/2).
- Open crimping pliers for fiber optic cable and remove fiber optic cable with brass pin contact.
Do not excessively bend or kink fiber optic cables. (min. bending radius 25 mm).
- Check the connection of brass pin contact - 2 - to fiber optic cable - 1 - for secure installation.
• 4 crimp points must be visible at brass connection pin.
• The brass pin contact must not be able to be removed by hand from fiber optic cable.
• The end face of the fiber-optic cable is located 0.01 to 0.1 mm behind the brass pin contact (visual inspection).
• Connector couplings are available for connecting fiber optic cables.
Installing Corrugated Tube on Fiber Optic Cable
- Cut the corrugated tube to the appropriate length.
• Use (VAS 6228) or a sharp knife for cutting.
• The corrugated tube must not be cut through using a side cutter under any circumstances
• The corrugated tube must be cut on the wave peak - arrow -, not in the wave trough.
- Guide fiber optic cable into (VAS 6223/10) as shown in illustration.
- Position crimping pliers for fiber optic cable at slot of corrugated tube.
- Position crimping pliers for fiber optic cable at slot of corrugated tube. By doing this, fiber optic cable is fed in corrugated tube.
Disconnecting from Wiring Harness Connector
Removing
- Unplug connector for fiber optic cable from appropriate control unit.
- Release locking latch in fiber optic cable connector - arrow -.
- Pull base module - 2 - for fiber optic cable from connector housing - 1 -.
• Mark allocation of fiber optic cable - 5 - to the appropriate connector socket in base module - 1 - with colored mark.
• Note the arrows - 3 - for allocation on the base module "IN" and "OUT".
- Release secondary latch - 6 - (blue pin) using a small screwdriver - arrow -.
- Release catch - 2 - and remove fiber optic cable - 5 - with brass connector pin - 4 - from base module - 1 -.
Installing
Install in reverse order of removal, observing the following:
- Install fiber optic cable in line with markings.
• Seal open harness connector - 2 - for fiber optic cable using protective cap for cable connector (VAS 6223/9) - item 1 -.
• Protective cap prevents contamination of or mechanical damage to end face of fiber optic cable which would impair signal transmission.
