Control Lines
When using the “over/under checkweighing” application program, you can use
the voltage level of four data output port lines to control an external online
display or control instrument. The voltage levels of the data output ports will change
according to various patterns, depending on the reference weight limit and on
the lower and upper weight limits.
Example: Control lines used only within check range:
Lower limit 30%; upper limit ∞% from setpoint
Menu code: 4 3 2*
30% Setp. Min. Setpoint Max.
LOW <
OK =
HIGH >
SET
Note:
When not in use, the voltage level is high: >2.4 V/+2 mA.
When in active use, the voltage level is low: <0.4V/–2 mA.
Caution: the output ports are not protected against short circuits!
