9.2.3 Batch Operation
In addition to weighing the conveyed material continuously, the
bulk flow measurement can also be used for batch weighing. This
operation mode allows, for example, to load trucks with a given
amount, or to control a feeding machine.
The following settings are required:
o
In the Measuring Parameter menu, select the product being
measured.
o
In the Measuring Parameter menu, select as Operating Mode the
mode Batch via keyboard or Batch via external .
o
In the I/O Config. menu, select Clear Ext. Batch Start/Mass In-
tegrator for Digital Input 1 if you want to perform an external
batch measurement.
o
In the I/O Config. menu, select Batch Ready for Digital Output
relay 3 and then enter the batch weight.
If the preset batch has passed through the measuring frame, a
signal is triggered at digital output relay 3 that can be used, for
example, to turn off the belt.
Another batch measurement can be carried out.
9.3 Operation with Different Materials
If various products requiring different calibrations are to be con-
veyed, you have to run separate calibrations for each product
(max. 10 different products).
The product can be selected either via keyboard by entering the
product number in the Measuring Parameter menu, item Measuring
Product. External selection is possible only for 2 different products
via digital input 3 (open = product 1, closed = product 2).
In the print protocol, the products are identified by the labels P1,
P2 ... P10.
