Life Fitness Insignia Series Owner's Manual page 48

BULGING:
Internal wire rope strands can break within and coil
causing a bulge to appear. Cable should retain same
outside diameter throughout.
FRAYED/EXPOSED WIRE ROPE:
Any exposed wire rope protruding through the casing or
at either end.
FLATTENED:
Section of cable is compressed and will not retain its
shape (outside diameter).
PERMANENTLY BENT:
Cable has 'kink' and prohibits cable from laying straight.
Wire rope may be unraveling beneath casing and is
compromised warranting replacement.
ENDS SEPARATING:
Watch for component end of cable to pull away from
cable assembly - look for exposed wire rope.
