Troubleshooting

Malfunction Possible cause
The clamping rod4 Incorrect pneumatic ac-
moves more than the tuation
max. permitted axial play
Permanent manual un-
despite an exhausted
locking
clamping cartridge2
Load too great and/or
static holding force ex-
ceeded
Contamination on the
clamping rod4
Clamping cartridge2 de-
fective
Wear
Clamping rod4 does not Insufficient operating
move despite an ex- pressure on the clamping
hausted clamping cart- cartridge2
ridge2
Clamping cartridge2 de-
fective
After pressurisation the Cylinder strikes against a
clamping rod4 moves to non-pressurised cham-
the end position at high ber
speed

Remedy
Check pneumatic actu-
ation
Remove the mounting
screw9 from the supply
port 1
Reduce holding force, do
not exceed static holding
force
( Maintenance and
care)
Replace clamping cart-
ridge2
Send clamping cart-
ridge2 to Festo
