Troubleshooting
Fault
Possible cause
Remedy
Unexpected swivelling and
gripping sequence
Pipe connection error
Check pipe connections
Proximity sensor not
sensing
Ferritic objects in the
immediate vicinity
(mounting attachments)
Use non−ferritic materials
or a different proximity
sensor type (SMT−10F−...)
Hard impact at the end
positions
Excessive load
Select a lighter load
positions
Excessive speed
Greater throttling of swivel
motion
Rubber buffer worn/
shockabsorber defective
Replace as described in the
section ’Operation’
The shock absorber can
puncture as the result of an
extended service life
Viscosity of the shock
absorber oil decreases as a
result of frictional heat
Reduce the swivelling
frequency
Shock absorber reset times
increasing in length
Oil leakage or increased
friction
Replace as described in the
section ’Operation’
Gripper jaws open during
swivel motion
Effective load exceeded
Check and if necessary
reduce effective load
Operating pressure at
gripper component too low
Check operating pressure
