Module opens or closes abruptly?
Possible cause Corrective action
Too little grease in the mechanical guiding
areas of the module Clean the module and relubricate it.

Compressed air lines are blocked Check the compressed air lines for crushing or
damage.
Mounting surface is not even enough Check the levelness of the bolting surface.
The gripping force drops?
Possible cause Corrective action
Compressed air can escape Check seals, if necessary disassemble module
and replace seals.
Too much grease in the mechanical mo-
tion spaces of the module Clean the module and relubricate it.

Module 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 module to the maximum that the movement
of the jaws occurs without bouncing and hitting.
Check compressed air lines.
Inner diameter of the compressed air lines are
sufficiently large relative to the compressed air
consumption
Compressed air lines between module and con-
trol valve shoud be kept as short as possible.
Flow rate of valve is sufficiently large relative
to the compressed air consumption.
If, despite of optimal air connections, the open-
ing and closing times are not achieved according
to the catalog, we recommend the use of quick
exhaust valves direct at the module.
