Trouble shooting

Module opens or closes abruptly?
Possible cause
Corrective action
Too little grease in the mechanical guid-
ing 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.
Pressure drops below minimum.
Check the air supply.
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.
NOTICE! The throttle check valve must not be
removed, even if the gripper does not achieve
the opening and closing times.
If, despite of optimal air connections, the open-
ing and closing times are not achieved accord-
ing to the catalog, we recommend the use of
quick exhaust valves direct at the module.
