By returning the melter to its factory setting many common melter problems
can be isolated to either a problem with the melter settings or the melter
hardware.
To return the melter to its factory settings, simultaneously press and hold the
Setup key and the right‐display UP arrow key, and then, while holding down
these keys, cycle the melter control switch off and on. When the melter
restarts, release the two keys.
Tables 6‐2 through 6‐5 describe the circuit board indicators, connection
points, and test points that are referred to in the troubleshooting flowchart.
Figure 6‐1 illustrates the location of each of these circuit board components.
