9.4 ESD Control Features
The Adept s350 CR/ESD robot is compatible with common magnetic semiconductor ESD
control measures. The surface of the robot is painted so that it is resistively coupled to the
robot ground. The bellows are also made of a resistive material that will conduct electrical
charges to the robot ground. This treatment precludes the buildup of any electrical charge
(such as tribocharging) on the robot surfaces. In addition, it is formulated to provide a
significant resistance to ground so that charged surfaces brought in close proximity to the
robot will slowly leak into the robot ground - rather than arc quickly to ground and create a
magnetic field event.

9.5 Maintenance
Bellows Replacement
Check the bellows periodically for cracks, wear, or damage. Replace the upper and lower
bellows if necessary, using the procedures below. Adept part numbers: 05555-000 (upper) and
05556-000 (lower).
Procedure for Lower Bellows Replacement
1. Remove the lower clamp ring from the bearing ring by loosening the screw on the
clamp. See Figure 9-3 for details.
2. Remove the tool flange. Refer to Removing and Reinstalling the Tool Flange on page 57
for the tool flange removal procedure.
3. Remove the upper clamp ring by loosening the screw on the clamp.
4. Slide the old bellows down off of the quill.
5. Install a new bellows, and reverse the steps listed above. Take care to correctly seat the
tool flange firmly up against its hardstop and rotate the flange so that the setscrew lies
in the middle of the machined flat of the quill.
