8.4.2Board Sensor Fault Isolation Procedure
The Board Sensor Fault Isolation Procedure consists of the following:
• Mechanical Verification
• Facility Power and Air Supply Verification
• Board Sensor Verification
• Conveyor Signals Cable 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.

system (such as loaders and ovens) before troubleshooting. Failure to do so may
result in serious personal injury or death.
CAUTION! Troubleshooting should only be performed by an Asymtek Field Service Engineer
or an Asymtek-trained service technician.
