7. Performance Confirmation & Diagnosis
Your model #RB3-065/035 VERSABALL® Gripper comes with a
diagnostic vacuum gauge installed at the auxiliary port. We
recommend the following procedure to confirm your gripper’s
performance immediately following installation. We recommend
using the large head for this test. Repeat the process below whenever
you change to a different head size. However, repeating this process
is not necessary when simply replacing a worn head with a newer
head of the same size.
1. The flow-control valve installed at your gripper’s release port is
shipped fully closed. Check that the valve is closed by turning
clockwise as shown in Figure 8.
2. Next, open the upstream solenoid valve connected to the gripper’s
release port, making sure you are able to close this valve again
quickly. No air should flow because the flow-control valve is fully
closed.
3. With the pressure on, slowly open the flow-control valve by turning
counter-clockwise so that air can begin flowing into the gripper.
Mechanisms within the gripper will limit the expansion of the balloon
head and prevent overinflation. Continue opening the flow-control
valve until the gripper’s balloon head reaches a steady-state
enlargement of about 10%. Use the black locking-nut to lock the flow-
control valve in this position, turn off the positive pressure, and
continue to the next step.
