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
movement 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.
NOTICE! 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.
7.2 Swivel movement is not executed immediately
Possible cause
Corrective action
Product stood still for a longer time.
• Vent piston chamber
• Open and close gripper 1x
• Depressurise gripper
