  Automatic Net Weight Discharge Cycle:

 
 
  1. Locate Net Weight Container in position to receive fill. Press START when ready.

  2. The scale will automatically Tare to Net Weight Zero, then start FAST FEED discharge, beginning the fill to the Net Weight Container.

  3. Upon achieving a preselected slow feed weight set-point, FAST FEED will stop, and SLOW FEED will start.

  4. Upon achieving a preselected cutoff weight set-point, the Net Weight Discharge will stop.

  5. The Net Weight amount discharged will automatically transmit to a printer and be accumulated internally in memory for later retrieval visually or as printable transmission.

  6. After completion of the data transfer, the system will automatically Clear Tare and Reset for a new cycle, beginning at Step #1.

 
 

Automatic Supply Hopper Refill Cycle:

 
 
  1. If at the end of a Discharge cycle, the weight of material remaining in the supply hopper is less than a preset Low Supply amount, another Discharge cycle will be prohibited and the system will automatically provide single speed REFILL control.

  2. When the supply hopper refills to a preset High Level weight amount, REFILL will stop, and the Automatic Net Weight Discharge cycle is once again enabled.
If the mushroom style Pull ON / Push OFF switch is pushed OFF at any time during the Discharge or Refill cycles, the sequence will immediately halt. The user will then have the option to either resume the cycle where it left off, or to abort a cycle and start over.
