  • Individual wires not detected → Cut off and replace contact part.
  • Insulation also crimped → Cut off and replace contact part.
  • Cable not far enough into contact part → Cut off and replace contact part.
  • Contact part not tin-plated → Cut off and replace contact part.
  • Sleeve oxidized/wrong → Cut off and replace contact part.
  • Improperly soldered/dry solder joint Resolder contact part, replace if necessary.
  • Plug-in area full of solder → Cut off and replace contact part.
• Fault with housing 
  • Screw connections loose Tighten screw connections again using configured torque wrench, replace if necessary.
  • Screw connections wrong/damaged → Replace screw connections (cable connector).
  • Coupling or connector housing damaged → Replace connector or housing.
  • Cap screw in handle recess missing/loose → Tighten cap screw, replace if necessary.
  • Coupling or connector housing not closed exactly → Firmly seal connector or housing.
• Cable fault 
  • Insulating tubing damaged → Rewind with PVC tape.
  • Insulation damaged → Cut through affected line at damaged area and repair using Raychem repair method.
  • Insulation pulled up → Cut through affected line at damaged area and repair using Raychem repair method.
  • Winding faulty → Rewind.
