3.6 Control Inputs (X3)
Six control inputs with HTL-PNP characteristics are available at terminal X5 pins
2, 3 and 4.
Control input 1 (Ctrl. In 1) to control input 2 (Ctrl. In 2) are freely configurable in
the COMMAND menu and are used for externally triggered functions such as
resetting the measurement result or for freezing the parallel output.
Control input 3(Ctrl. In 3) is used exclusively for resetting the device parameters
to the "default" values and is therefore not freely configurable.
An HTL pulse (rising edge) at Ctrl. In 3 resets the device to factory settings. The HTL
pulse must be present for at least one second.
Connection of the control inputs:
Generally, open control inputs are "LOW."
The input stages are designed for electronic control signals.
Note for mechanical switching contacts:
With mechanical contacts as a pulse source, a commercially available external
capacitor of approx. 10 µF must be installed between GND (-) and the
corresponding input (+). This attenuates the maximum input frequency to
approximately 20 Hz and suppresses bouncing.
