NOTE See Appendix A for a list of replacement shuttler gripper parts.
For ease of reinstallation, note the location, orientation, and routing of the wiring, tubing,
and any additional components before removing them.
Retain all components and fasteners removed during this procedure in an orderly manner
and in a safe location for reinstallation or shipment back to Nordson.
To remove the shuttle gripper assembly:
CAUTION! This procedure should only be performed by a trained service
technician.
1. Perform a service shutdown, see 2.11 Service Shutdown.
2. Open the front door.
3. Pull the gripper assembly toward the front of the system.
4. Remove the electrical wires and air lines from the cable tie located at the mounting plate.
5. Disconnect the electrical connector located at the center of the gripper.
6. Disconnect both air lines from the gripper actuator at the push-in connectors.
7. Using a 4 mm Allen key, locate and remove the three mounting screws from the mounting
plate.
„ Even though the mounting plate is pinned to the Y-Axis drive assembly, use caution
when removing the last bolt, because the assembly could dislodge from the alignment
pins and fall.
8. Perform the necessary service or inspection, such as replacement of the gripper fingers.
9. Wipe down both mounting surfaces using a soft cloth and isopropyl alcohol.
10. Reassemble in reverse order.
11. Check alignment of the gripper assembly by manually picking and placing process carriers
to ensure proper reassembly and repeatability. Adjust if necessary.
