Function of switch S6
Table 20: Switch S6: SGND - GND
Switch setting
Function
ON
GND of the trigger sensor connected with GND of CDM420-0006 and
GND of the device
OFF
Trigger sensor connected potential-free at CDM420-0006 and device.
Common, isolated reference potential of all digital inputs is SGND.
