Monitor Melter Faults
The melter alerts the operator to the faults listed in Table 4-2. Faults affect
the melter in one of three ways: the heaters turn off; the heaters remain on,
but the fault condition persists; or the melter stops functioning.
When a fault occurs, you must diagnose and correct the fault condition and
then place the melter back into operation. You can use the fault log to
determine the type, order, and relative time of the last ten faults.
