Error
Vacuum level is not
reach or vacuum is
created too slowly
Load cannot be held
Sealing plate wears
out very quickly
Only FMCB:
External vacuum gen-
erator works, but
workpieces are not
picked up
Only FXCB:
Internal vacuum gen-
erator works, but
workpieces are not
picked up

Possible cause
Leakage in hose line
Leakage or wear on the sealing
plates/sealing
Ejectors are dirty (only FXCB)
Vacuum level too low
Suction force not suitable for load
Flow restrictors are dirty
The area gripper is not pressed
firmly enough onto the workpiece
to be lifted
Too short retention time for the
area gripper on the workpiece
Too fast or jerky lifting of workpiec-
es
The workpieces to be lifted are not
suitable for the area grippers (e.g.
non-rigid).
The area gripper is angled or
makes a grinding noise when ap-
plied to the workpiece to be lifted
If present: The dust filter of the
vacuum generator is dirty
The sealing mat is damaged/torn
Workpiece is too heavy
Vacuum is too high
The sealing mat is not applied firm-
ly enough
The sealing mat is damaged/torn
Workpiece is too heavy
Input pressure is too low
The ejectors are dirty
The sealing mat is not applied firm-
ly enough

TROUBLESHOOTING
Solution
Check hose connections
Check the sealing plates/sealing and
replace if necessary
Remove and clean ejectors
See above for possible causes
Increase vacuum or connect additional
grippers if necessary
Clean the masking film
Press the area gripper more firmly onto
the surface. On even surfaces, we rec-
ommend that the foam compress by at
least 50%.
Extend the retention time
Optimize the motion. Avoid acceleration
peaks (especially when lifting the work-
pieces)
Use a different gripping system.
Set it down vertically on the workpiece
Clean or replace dust filter
Replace sealing mat
Workpiece is not suitable
Determine the maximum possible vacu-
um of the vacuum generator; check the
system for leaks (hose connections,
sealing, etc.); valves are dirty; the work-
piece is too porous
Press the area gripper more firmly onto
the surface. On even surfaces, we rec-
ommend that the foam compress by at
least around 50%.
Replace sealing mat
Workpiece is not suitable
Increase the input pressure. Check the
hoses for leakage. The workpiece is too
porous
Remove and clean ejectors
Press the area gripper more firmly onto
the surface. On even surfaces, we rec-
ommend that the foam compress by at
least around 50%.
