The PMAC Mechanical Fault isolation Procedure consists of the following:
• X and Y-axis Mechanical Verification
• Servo Motor Verification
Before troubleshooting a problem, please familiarize yourself with the important information provided in
the Safety section of this manual.
WARNING! A dispensing system in need of troubleshooting may have high voltage present in
both designated and unsuspected places that can result in personal injury or
death. Follow safety precautions listed in the Safety section of this manual.
