Installing the ventilation connection
The ventilation line is designed to compensate for changes in
volume inside the gripper due to gripper movement. It ensures no
vacuums are created inside the gripper and that no dirt is thus
sucked into the gripper.
NOTE
Make sure the ventilation line is assembled in a clean
environment so that no dirt or liquid can be sucked into the
gripper.
Ø
Remove the sinter filter (2) from the purge air connection (1).
Ø
Connect the ventilation line (3) to the purge air connection (1).
Ø
Place the hose end in a clean area.
Ø
If necessary, attach a filter to the end of the hose in order to
prevent ingress of foreign bodies as much as possible.
Fitting the air purge connection
During operation using air purge, excess pressure may occur. If the
gripper is not sufficiently relieved of excess pressure, the gripper
jaws may close slowly or with a jolt. Excess pressure needs to be
released via a pressure control valve with secondary venting, see
Actuation plan "1V2". This ensures air purge pressure remains
constant. For a recommendation regarding a suitable pressure
control valve with secondary venting, contact Technical Sales.
Ø
Remove the sinter filter (2) from the purge air connection (1).
Ø
Connect air purge via a pressure control valve with secondary
venting (3) at the purge air connection (1).
Ø
Set the air purge pressure between 0.2 bar and a maximum
0.5 bar. The air purge pressure must be present constantly.
