The Heater Fault Isolation Procedure consists of the following:
Mechanical Verification
Heater Verification
Temperature Controller 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.
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.
WARNING! Do not touch any heated elements while the System is powered up. Personal
injury and severe burn may result if hot heater elements are contacted. Heated
elements will stay hot even after System power down. Always allow heated
elements to cool down before contact.
CAUTION! Troubleshooting should only be performed by an Asymtek Field Service Engineer
or an Asymtek-trained service technician.
