Part 1120130
The Nordson AltaBlue Touch Adhesive melter diagnoses many alert and
fault conditions that may occur during operation. An "alert" condition is a
situation in which a potential problem may be occurring with the melter,
pump, applicator or hose. The melter will operate under an "alert" condition
unless the problem goes unresolved, at which point the melter will go into a
"fault" condition, during which the melter will shut down until the problem is
resolved.
Refer to the appropriate table for more information.
