8.5.2 Tactile Sensor or Needle Sensor Fault Isolation Procedure

The Tactile Sensor and Needle Sensor Fault Isolation Procedure consists of the following:

• Dispensing Calibration Module Verification

• Tactile Sensor Verification

• Needle Sensor 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 component 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.

WARNING! Disconnect and lock out power to adjacent systems connected to the dispensing

system (such as loaders and ovens) before troubleshooting. Failure to do so may

result in serious personal injury or death.
