Page 15: Mechanical Installation
Mechanical installation Note When lifting the SITRANS WW310 Weighfeeder, connect to the lifting points at the legs of the unit, and follow local governing code for lifting/hoisting. Perform a thorough and systematic inspection of containers immediately upon receipt of your Siemens weighfeeder. -
Page 16: Installation
Securely fasten the unit to the rigid, level structure constructed in Step 1 (Page 14). Use a level for verification and shim as necessary. Prevent any twisting of the frame that may affect weighfeeder performance. Note The inlet and discharge of the weighfeeder will not support load. SITRANS WW310 Operating Instructions, 03/2014, A5E33490433-AA... - Page 17 Remove only the tagged shipping bolt that is attached to the load cell. This bolt supports the weighbridge during transport and installation. Note DO NOT loosen or tighten the overload bolt—it has been factory set to minimize the possibility of load cell damage resulting from incidental overload.

Page 25: Start Up
Shear gate The shear gate on the inlet of the weighfeeder needs to be set to allow the maximum feedrate 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. -
Page 26: Changing The Conveyer Belt
From the access side of the feeder at the discharge end, grab the edge of the belt and gently pull it over the side rail, making sure that the leading edge of the belt does not catch on any components. SITRANS WW310 Operating Instructions, 03/2014, A5E33490433-AA... -
Page 27: Belt Tension
Specific belt tension cannot be given because the weighfeeder could be mounted in various applications. As a general guideline, the bottom of the belt should droop 1-2 inches over the SITRANS WW310 Operating Instructions, 03/2014, A5E33490433-AA... -

2. Loosen the jam nut. 3. Turn the adjusting screw in the desired direction. Often, only a small amount of adjustment (1 turn or less) will be required. SITRANS WW310 Operating Instructions, 03/2014, A5E33490433-AA... - Page 29 5. Re-tighten the jam nut located on the telescoper to maintain the new telescoper position after completing the tracking procedure. 6. If you are having problems tracking the belt, consult your Siemens representative. Common causes of belt tracking problems are: uneven or improperly distributed product loading, twisted frame, or product build-up on head or tail pulleys.

Page 30: Load Cell Replacement
If a load cell on SITRANS WW310 Weighfeeder has been damaged and is not functioning, or if you are changing the capacity, you will need to replace one or all load cells. - Page 31 Be careful not to move the idler as it is still attached to the load cell on the other side of the weighfeeder. Step 4 Remove the two bottom load cell mount bolts. Step 5 Remove the load cell off the feeder. SITRANS WW310 Operating Instructions, 03/2014, A5E33490433-AA...
