Batcher Fails To Open
The batcher gate on the surge bin when in the automatic mode (selected when in production) is time controlled by the PLC.
An "open" time and a "closed" time have been input (see Maintenance manual for additional information). The gate cycles
open and then closed continuously while the plant is producing. Failure of the gate to open when signaled could cause the
plant to shut down with hot mix in the components. This could result in damage to the equipment if the hot mix cools and
Motor control panel-set Batcher to the OPEN position.

Motor control panel-press STOP button on Hot Mix Conveyor.
Burner control panel-select OFF on the Main Flame selector switch.
Feeder panel-verify that the Divert light switches from Drum to DIVERT.
Motor control panel-press STOP button on Exhaust Fan.
