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 guns. 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.

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 correct voltage plug is installed on terminal J1. Refer to Section 3,
Installation, for information about selecting the correct voltage plug.
S
external inputs (if used) are functioning properly.
S
the standby or clock functions are not turned on (if not required or
expected at the current time).
