Function of switch S3
Table 14: Switch S3: SGND-GND
Switch setting
Function
ON
GND of the trigger sensor is connected with GND of CDB650-204 and
GND of the device
OFF
Trigger sensor is connected volt-free at CDB650-204 and the device.
Common, isolated reference potential of all digital inputs is SGND.

Switching behavior
Power to the input starts the assigned function, e.g. start analysis.
Default setting in the device: logic not inverted (active high), debounce
time 10 ms
Properties
•
