Batchweighers are typically used for control of industrial concrete mixers but can also control just about anything that requires a repetitive recipe mix. The freely programmable inputs, function keys, displays and outputs results in a batchweighing system with tremendous flexibility. The setup allows for a maximum of five ingredients. Each can be named (Sand, Cement, etc), have an interlock, time delay or auto zero maintenance(AZM). In the setpoint values section up to four recipes (A,B,C or D) can be set. With these selections most batching systems can be customised, even on site if need be.

How it works

Select RUN BATCHWEIGHER 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, Batch menus, 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 require. Descriptions of these are listed in the Service menu pages.

The Batchweigher Service menu contains the following functions:-

01,03,05,07 SP values A to D Set values for setpoints 1-6 in Recipes A-D
02,04,06, 08 Batch menus A to D Select 1 to 5 materials & timing for A-D
09 Set Point Configuration Select functions for setpoint 1-6

10 Analog output Select output 1-5V, 0-10V, 0-20mA or 4-20mA
11 Communications Select and set up serial output
12 Auto zero Select and set up Auto Zero Maintenance (AZM)

13 Security level Select access to Operator and/or Service menu
14 Precalibrate Set loadcell values, excitation, range, damping

15 Zero trim Trim off empty weighbin (backbalance)
16 Span trim Trim range using test weights totalisers in kg only
17 Lineariser Select up to 15 points of linearising

18 Simulate For testing, force analog and relay outputs
19 Function keys Set functions for keys F1-4
20 Digital inputs Set functions for inputs D1-6
