- Visual inspection
Inspecting the connectors
Use this procedure to check the connectors.
Illustration/Note Action
Check that the connectors at the robot base,
track motor and interchange to the floor cable
are correctly fitted and that there is no risk of
loose connections. 1
Inspecting the cables
Use this procedure to check the cables.
Illustration/Note Action
Check if any cables have been damaged
through wear or pinching. If damaged then re-
place the cable. 1
See cable routing in Replacing the
cables on page 253 .
Check if any cables rub against sharp edges.
If so, route the cable so that it runs freely. 2
Check strain relief of cables and hoses. Marking
should be close to the corresponding strap. 3
If not, pull the hose/cable to the correct position
and strap it.
Fault finding
The following information is provided to assist fault finding.
Cables that have failed due to incorrect installation typically show the following
symptoms:
• Knotting of conductors underneath the cable jacket.
• Cables twist around one another within a cable carriage system.
• Cables are sticking out between the cable carriage crossbars and getting
caught in the bend radius.
• Cables entangled with other cables and crossbars tearing them apart.
• Loss of conductivity through simple breaking of cable conductors.
Common causes of cable failure when operating in a cable chain:
• Cables used are not designed for use in continuous flexing operation.
• Cables are packed too tight inside the carriage cavities.
• Cables are not properly adjusted (see Inspection of cables and covers prior
to start-up on page 122 ).
