Using the Troubleshooting Flow Chart
The flowchart, which is provided at the end of this section, is designed to
assist you in diagnosing and correcting a complete or partial stop in hot melt
output from the applicators. The chart is organized in a simple
question‐action block format. If your response to a question is yes (Y),
continue downward in the chart to the next question or action block. If you
response is no (N), 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:
S Refer to information provided elsewhere in this manual
S Replace a component
S Complete a diagnostic procedure (DP.x)
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.
Troubleshooting Quick‐checks
Before using the troubleshooting charts confirm:
S whether or not service was recently performed on the melter or the
melter's settings were recently adjusted.
S the standby or clock functions are not turned on (if not required or
expected at the current time).
