The Control Input / Output interface, consists of 6 inputs and 6 outputs, is intended for
inputting/outputting weighing control signals to an external unit.
The capability of each input/output terminal can be selected at its function setting, except COM
(common).
Settings
Control Input
* A signal is accepted at the timing when the level goes from OFF to ON (Edge-Input), and when the
level stays ON (Level-Input).
* "Input ON" is a status that each input terminal is shorted to the common terminal.
* Set 50 ms or longer for the ON time and OFF time since chattering is protected.
Input is accepted only in the normal mode. In a mode like the OFF mode, input will not be
accepted to avoid wrong operations.
Control Output
* "Output ON" is a status that each input terminal is shorted to the common terminal.
Each output terminal is turned OFF in a mode other than the normal mode to avoid wrong
operations.
