4.2 Air connection
NOTICE
Damage to the gripper is possible!
If the maximum permissible finger weight or the permissible
mass moment of inertia of the fingers is exceeded, the gripper
can be damaged.
• A jaw movement always has to be without jerks and bounce.
• You must therefore implement sufficient reduction and/or
damping.
• Observe the diagrams and information in the catalog data
sheet.
NOTE
• Observe the requirements for the compressed air supply,
Technical data [}14].
• In case of compressed air loss (cutting off the energy line), the
components lose their dynamic effects and do not remain in a
secure position. However, the use of a SDV-P pressure
maintenance valve is recommended in this case in order to
maintain the dynamic effect for some time. Product variants
are also offered with mechanical gripping force via springs,
which also ensure a minimum clamping force in the event of a
pressure drop.

Assembly
Adjusting the
hysteresis
The hysteresis to both switching points will be adjusted
automatically corresponding to the characteristics of the magnetic
field.
The user can set the switching and trigging points of each position
a little bit closer than for the automatic mode. The trigging point is
closer to the switching point. At the same time the susceptibility to
trouble and damage increases. In the mode of the lowest
hysteresis, an error signal (such as jitter or untimely switch off) can
be avoided, if the sensor is protected against all types of
disturbances (i.e. by shielding). Frequent types of disturbances are
change in temperature and electro-magnetic influences.
Within the closest fine-teach mode, SCHUNK cannot guarantee
EMC-compatibility any more.
The hysteresis adjustment is used for the manual adjustment of
the switching points (if necessary).
In case that the hysteresis automatically determined by the sensor
should be too high or too low after “the adjustment of the
switching points”, you may correct the value as follows.
The sensor avoids a too small hysteresis during hysteresis
adjustment.
