Component part defective. Replace component or send it to SCHUNK
for repair.
6.5 Product does not achieve the opening and closing times
Possible cause Corrective action
Compressed air lines are not installed optim-
ally.
If present: Open the flow control couplings
on the module to the maximum that the
movement of the jaws occurs without boun-
cing and hitting.
Check compressed air lines.
Inner diameters of compressed air lines are
of sufficient size in relation to compressed
air consumption.
Keep compressed air lines between the
product and directional control valve as
short as possible.
Flow rate of valve is sufficiently large relat-
ive to the compressed air consumption.
NOTICE!The throttle check valve must not
be removed, even if the product has not
reached the opening and closing times.
If you still cannot achieve the open and close
times mentioned in the latest catalog, we re-
commend the use of quick-air-vent-valves
directly at the product.
