How F1, F2, and F3 Faults are Handled

When the melter detects an F1, F2, or an F3 fault:
1. The automatic scan stops and the melter begins to monitor the potential
fault for up to two minutes. The ready and heater LEDs remain on during
the two‐minute time period. If, at any time during the two‐minute period,
the melter detects that the fault condition no longer exists, the melter will
return to the automatic scan mode.
2. The LED on the affected component key (tank, hose, or gun) turns on to
indicate the type of component that has, or is, failing.
3. The right display indicates the type of fault (F1, F2, or F3).
4. The left display indicates, as follows, the component that has, or is,
failing.

If the LED on the tank key is on, the left display will indicate either 1

the number of the affected hose or gun.
5. If the fault condition still exists at the end of the two‐minute monitoring
period, the ready LED will turn off, the red fault LED will turn on, the
heaters turn off, and the melter records the fault in the fault log. Refer to
