Function of switch S3
Table 58: Switch S3: SGND - GND
Switch setting Function
ON GND of the trigger sensor connected with GND of CDB620-001 and
GND of the device
OFF Trigger sensor connected potential-free at CDB620-001 and device.
Common, isolated reference potential of all digital inputs is SGND.
Characteristic data of the digital inputs

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