Page 5: Safety Notes
Milltronics WD600 weighdeck is used in conjunction with the selected integrator and speed sensor. This manual covers only WD600 installation and operating procedures. For the complete library of Siemens manuals, go to: www.siemens.com/processautomation. -
Page 6: Wd600
WD600 load cells output an electrical signal proportional to load, which is applied to the selected Siemens belt scale integrator. Thus, weighing is accomplished without interrupting the process and without affecting the process material. -

Page 9: Operation
Operation WD600 works with an existing flat belt conveyor and the selected Siemens integrator. As material is moving along the conveyor belt and travels over the belt scale, it exerts a force proportional to the material load through the suspended weighbridge to the load cells. -
Page 10: Installation
Adjust pulleys to ensure that the conveyor belt tracks straight and centrally from the head to the tail pulley. To limit the weight and dimensions of the weighbridge on the scale, Siemens builds the weighbridge to definite specifications as part of the scale. If a substitute or a replacement is required, please contact Siemens. -
Page 11: Load Cell Handling
Load Cell Handling WD600 is designed for low-to-medium capacity operation and is constructed using two load cells. Although the load cells are protected by shipping screws that keep the cells from moving, care should be taken when handling the scale to avoid damaging the cells. The screws are bolts about 38 mm (1.5") long located beneath the load cell mount pads and threading into the load cell. -

Remove the existing flat roll idler (or flat slider pan) from the area selected to locate the belt scale assembly. - Page 13 Idler Alignment Precise alignment is very important to achieve maximum accuracy of the weighing system. Improperly aligned idlers could cause unwanted forces to be applied to the weighbridge, resulting in measurement errors. Alignment Procedure Remove the shipping stops to free the weighing mechanism. •...

Page 15: Calibration
Calibration General After the WD600 has been installed in accordance with the installation procedure, calibration of the weighing system must be done in conjunction with the selected integrator. Refer to the integrator instruction manual for programming and calibration. The calibration is initially done using a calibration test weight. Where possible, material tests are recommended to achieve maximum accuracy. -
Page 16: Maintenance
Maintenance Because the WD600 has no moving parts, the scale requires no active maintenance. Once the scale is installed into the conveyor, the conveyor becomes part of the total weighing system. If a problem develops with the conveyor, that problem may also affect the scale. -
