When lifting the weighfeeder, connect to the lifting points at the top of the unit or structural frame, and follow local governing code for lifting/hoisting. Perform a thorough and systematic inspection of containers immediately upon receipt of your Siemens weighfeeder. The containers are packed to separate each item and provide protection during shipping. Note Do not remove equipment from shipping crates or boxes until you check for possible shipping damage. - Page 12 9. Before starting the weighfeeder, make a final check to see that the conveyor belt is free of all tools and foreign objects, and that the infeed/skirtboards are not pinching against the belt.

Design Rate, Design Speed, and Design Load. You are interested in the Design Speed: this will aid in setting the Maximum RPM – P2000. Calculating P2000 Design Speed P14 refers to Parameter 14 of the Siemens integrator BW500. Please see the Technical Report supplied with the weighfeeder. Imperial: P2000 = Design Speed (P14-BW500) * k Factor (47.28702) - Page 18 7. To save this new setting, press and hold for 3 seconds.

Disregard for horseshoe-style infeeds. The shear gate on the inlet of the weighfeeder needs to be set to allow the maximum feed rate capacity required. Consult your Siemens representative if feed rate changes are required. Skirtboards The skirtboards have been factory set to proper specifications. Note that near the inlet, the skirtboards are very close to the belt. -
