Part 1032059B
The flow chart is designed to assist you in diagnosing and correcting a
complete or partial stop in hot melt output from the guns. The chart is
organized in a simple question-action block format. If your response to a
question is yes, continue downward in the chart to the next question or
action block. If you response is no, continue to the right to the next question
or action block. All diagnostic paths within the chart end with an action block
that specifies one of the following three courses of action:

To return your melter to service as quickly as possible, the chart is designed
under the assumption that it is preferable to immediately replace a faulty
assembly as opposed to conducting detailed diagnostics and repair of the
assembly while the melter is out of service.
Use of the chart assumes that the melter is installed correctly and that it is
set up to support the current manufacturing process. Refer to Section 3,
Installation , for information about installing and setting up the melter.
Table 6-3 provides detailed descriptions of the circuit board indicators,
connection points, and test points that are referred to in the troubleshooting
chart. Figure 6-1 illustrates the location of each of these circuit board
components.
