You can avoid most problems by following the recommended installation and maintenance
procedures outlined in this User Guide. If you do have a problem, this section will help you

Before you begin troubleshooting:
•
Find the wiring diagrams and other schematics that were shipped with your equip-
ment. These diagrams are the best reference for correcting a problem. The diagrams
also will note any custom features, such as special wiring or control options, not cov-
ered in this user guide.
•

trol systems and its components.
Additional details about troubleshooting and repairing specific components are in this

stream from the TrueBlend SB-4 system. Solving problems related to material coveyed
to the TrueBlend SB-4 or due to poor extrusion or injection quality may require trou-
bleshooting malfunctions or incorrect operating procedures on other pieces of equip-
ment on the production line.
