The beltweigher measures the weight of material on a conveyor belt and it's speed, from this a mass flow is calculated such as kg/min or tonnes/hr. The 6004MF allows you to set or measure a belt speed, and, if measure, to set the pulley diameter, encoder pulses/rev and also to enter the weighsection length. With this information and the precalibrate feature described above the material flow rate will be calculated and displayed. Zero trim is selectable for length & number of revolutions or time, and, if some form of check weighing is available, a rate correction factor can be inserted. All rates have a main totaliser as well as a resettable totaliser. The totaliser can be set for remote display through one of the setpoint outputs using an optional photomos solid state relay which is ideal for this purpose. The PI control selection used with a variable speed drive can convert the beltweigher into a flow controller.

How it works

Select RUN BELTWEIGHER if not already in this application. Press side arrow after power up when RUN (application) is displayed, key in password, enter and use side arrows to select, then enter again. For quicker commissioning first select Security Level 1 and connect the Hardlock link. Going in to the Service menu select Calibrate, not view, in order to change settings. Change Security levels and passwords last. Note that you make changes to the whole Service menu block then press Enter.

It is advisable to first set up the Displays, Digital inputs, Function keys, then Beltweigher Settings, then go to Precalibrate and set up loadcell values and scales. After this you can go through the Service menu blocks to select and set other functions that you require.

Final calibration trim can be carried out on the system using Zero Trim (manual, length or time) in Service menu or activate via Belt Zero using Function keys or Digital inputs. If test weights are available use Span Trim. The Beltweigher has a Rate Correction Factor that can be used later.
