Operating instructions FX460

Namur
Tri-State
Open PNP inputs are generally "LOW" and open NPN inputs "HIGH"�
The input stages are designed for electronic pulse pick-ups�
Remark on mechanical switching contacts:
If mechanical contacts are to be used as pulse source, a standard, external
capacitor of about 10 μF must be connected to the terminals between GND (-) and
the corresponding input (+)� This damps the maximum input frequency to approx�
20 Hz and contact bouncing is suppressed�
7.4 Control inputs
On terminals 10, 11 and 12, three control inputs with HTL-PNP characteristic are
available�
These inputs can be configured in the COMMAND MENU and are used for
functions that can be triggered externally such as resetting the display value,
changing the display, locking buttons of the touch screen or releasing the latching
of control outputs�
Connection of the control inputs
