7 Troubleshooting
7.1 Product does not achieve the opening and closing times
Possible cause Corrective action
Compressed air lines are not installed
optimally.
If present: Open the flow control couplings on
the product to the maximum that the move-
ment of the jaws occurs without bouncing
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 relative
to the compressed air consumption.
IMPORTANT!The throttle check valve must not be
removed, even if the product has not reached the
opening and closing times.
If, despite optimum air connections, the
opening and closing times specified in the
catalogue are not achieved, SCHUNK
recommends the use of quick-air-vent-
valves directly at the product.
Loading too large. Check permissible weight and length of the
gripper fingers.
