9.2 Faults, Causes, Solutions
Fault
Vacuum level is
not reached or
vacuum is created
too slowly
Load cannot be
held
Suction cups wear
out very quickly
Version for ext.
vacuum generator
only: External vac-
uum generator
EN-US · 30.30.01.02459 · 00 · 08/20
Possible cause
Leakage in hose line
Leakage or wear on the suction cup/
sealing
Vacuum generator of the SEP nozzle or
foam inserts in the silencer dirty
Quick-change adapter is not attached
to the swiveling unit/is tilted
Vacuum level too low
Suction force not suitable for load
The gripper is not pressed firmly
enough onto the workpiece to be lifted
Too short retention time for the grip-
per on the workpiece to be lifted
Too fast or jerky lifting of workpieces
The workpieces to be lifted are not suit-
able for the grippers
The suction cup is angled or makes a
grinding noise when applied to the
workpiece to be lifted
If present: The dust filter of the vacuum
generator is dirty
Suction cup is damaged/torn
Solution
Check hose connections
Check the suction cup/sealing and re-
place if necessary
Remove and clean the SEP nozzle or
foam inserts in the silencer
Manually remove the quick-change
adapter, check it for damage, check its
function and reconnect it
See above for possible causes
Increase vacuum if necessary or connect
more suitable suction cups
Press the gripper more firmly onto the
workpiece. On even surfaces, we rec-
ommend compressing the suction cup
by at least 50%
Extend the retention time
Optimize the motion Avoid accelera-
tion peaks (especially when lifting the
workpieces)
Use a different gripping system
Set it down vertically on the workpiece
Clean or replace dust filter
Replace suction cup
