6 Troubleshooting

6.1 Checking the opening and closing times

If you cannot reach the opening and closing times mentioned in
the latest catalog, please check the following:

Ø

Flow control valves are opened to the maximum extent possible?
(Movement still has to be shock-free!)

Ø

Inner diameter of air hoses is sufficient for the gripper’s air
consumption?

Ø

Air hose between valve and gripper is as short as possible?

Ø

Flow rate of valve is sufficient for the gripper’s air consumption?

If you still cannot achieve the cycle times mentioned in the latest
catalog, we recommend the use of quick-air-vent-valves directly at
the gripper.
