7 Troubleshooting
7.1 Overview
If you have difficulty operating your cure module, use this section to identify a possible solution to the
problem. If you have difficulties not listed in this section, or the suggested solution does not correct the
problem, contact Nordson ASYMTEK Technical Support.
7.2 Safety First
Operation of your UV-9 Cure Module involves air pressure, electrical power, mechanical devices, and
potentially the use of hazardous materials. It is essential that every person servicing or operating the cure
module fully understands all hazards, risks, and safety precautions. Refer to Section 2 – Safety for
important safety information.
WARNING! CAUTION!
Allow only qualified personnel to perform system troubleshooting. Observe and
follow the safety instructions in this document and all other related documentation.
Failure to do so may cause serious bodily injury to the user or damage to the
equipment.
7.3 Record Keeping
The type of procedure performed should be recorded in maintenance records for the dispensing system.
Dates, part numbers/serial numbers of replaced parts, names of technicians, and other pertinent data
should be recorded.
