9 Ready for use
The [OUTPUT] (4.3.1) "Set" output normally changes its voltage level when the load is near
the target weight. Alternatively, you can assign the [OP.READY] (4.3.2) "Ready for use"
function to this port.
Setting: [APPLIC.] - [APPLIC.2] - [CHECK.WG] - [CTRL.SET] (4.3) (see chapter
6.1.2.1 ).
This makes it possible, for example, to connect a simple indicator for weighing or
calculation results.
All data output ports have a high voltage level when the application is not initialized.
Output port speciications :
- When not in use, the voltage level is high: >3,7 V
- When activated, the voltage level is low: <0,4 V
Note:
The outputs are not protected against short circuits and are not galvanically isolated.
7.11.8 Example 1: Checkweighing
Checkweighing samples with a target weight of 1250 g and a tolerance range from –10 g
to +30 g. The tolerance values should be entered as absolute values (lower and upper
tolerance limit).
Coniguration: The "Checkweighing" application is selected using the setting [INPUT] -
[TAR.MN.MX] (4.5.1), a printout has been set up (see chapter 7.16 ).
