CAUTION!
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.
CAUTION!
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 a new fiber optic cable in a wiring harness connector. Refer to => [ Disconnecting from Wiring Harness Connector ].
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 -.
CAUTION!
• 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.
