Monitor Melter Faults (contd)
To put the melter back into operation
1. Diagnose and correct the fault condition. Refer to Section 6,
Troubleshooting, for information about diagnosing and correcting fault
conditions.
NOTE: When a fatal F4 fault exists, the control switch will not function.
Remove power to the melter at the local disconnect switch.
2. Return the melter to the automatic scan mode by pressing the Setup key
twice.
3. Press the Clear/Reset key.
4. Press the Heater key to turn on the heaters.
To view the temperature of a
heated component when an F2 or F3
fault exists, simultaneously press and
hold both of the right‐display scroll
keys.
You can temporarily dismiss an
F1fault (RTD) and return to the
automatic scan mode by pressing the
Clear/Reset key. The heaters will,
however, remain off. If the fault
condition still exists two minutes after
pressing the clear/reset key, the fault
LED will turn back on.
When an F1 fault code appears, you
can determine whether the fault was
caused by an open or a shorted RTD
by simultaneously pressing both of the
right‐display scroll keys. If the right
display indicates OP, the RTD is open,
if it indicates SH, the RTD has shorted.
If, for any reason, a component
reaches
235 _C (458 _F), an immediate F3 fault
will occur (no two‐minute monitoring
period).
If F4 appears in the right display when
you press the clock key, the internal
clock function has failed.
