Troubleshooting
Issue
Cause
Remedies
O-ring not installed or pulled out again
Is the O-ring position on the spread jaw
correct after being picked up by the
gripper?
► Check the pickup position
Was the O-ring picked up correctly by the
spread jaw?
► Check the immersion depth of the
spread jaw
► Check the pickup position of the
gripper
Is the gripper position to the workpiece
correct and is the position of the O-ring to
the recess correct?
► Check the exact position
Was the O-ring removed when retracting
the gripper into the workpiece?
► Check the installation position, the
gripper needs to be retracted exactly
into the center of the hole
The distance between the spread jaws
and workpiece housing is too small,
the O-ring cannot slide into the annular
groove
► Reduce the stroke of the spread jaw
using the adjustment ring

Is the programmed time sufficient to
develop the O-rings?
The required times vary as a result of,
material factors, cross-section, O-ring
diameter and the outside temperature.
These can be determined through tests
The clamping jaw straight pins are not
pressed in far enough for the wiper to be
able to eject them
► Check to see if the wiper is over the
straight pin when it is extended.
Clamping jaws no longer move to the
home position
► The three gripper jaws need to have
approximately the same position
to each other. If one gripper jaw
protrudes further than the rest and
is on the wiper, this can cause the
gripper's mechanical system to jam.
► Readjust the clamping jaws and make
sure that only the internal stop limit of
gripper limits the stroke!
Clamping jaw pins touch the spread jaws
when retracting.
► Please refer to the clamping jaw
drawings for the push-in depth of the
pin. The pins should be pushed in until
they are approximately 0.3 mm below
the contact area of the clamping jaw.
