Function of switch S3
Table 52: Switch S3: SGND - GND
Switch setting Function
ON GND of the trigger sensor connected with GND of CDB650-204 and
GND of the device
OFF Trigger sensor connected potential-free at CDB650-204 and device.
Common, isolated reference potential of all digital switching inputs is
SGND.
Characteristic data of digital switching inputs
