Throughput weigher Applications

A throughput weigher makes use of a small weighbin to weigh and dump batches in quick succession typically used in bulk handling of cereals. The flexibility of the 6004MF allows you to set high and low levels of the weighbin and various time delays in order to tune the throughput weigher for maximum efficiency. The main LED display can be the resettable totaliser and a non-reset totaliser can be on the auxilliary LCD display

How it works

Select RUN THROUGHPUT WEIGHER 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, Throughput Settings, SP Configuration and Setpoint Values, 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 may require. Descriptions of these are listed in the Service menu pages.

Final calibration trim can be carried out on the system using Zero Trim and, if test weights are available, Span trim.
