  2. Melter ready light (green)
  3. Refill alarm LED (red)
  4. Fill system enable key

  6. Enter key
Note:  When the refill alarm output is activated, the melter heaters stay on and the melter ready remote output remains active.
  1. Press the Fill System Enable key (4) to disable the fill system and the alarm.
  2. Correct the fault condition.
  3. Press the Clear/Reset key (5).
  4. Press the Fill System Enable key (4) to enable the fill system.
