In the following datasheet.

At some point it says : "If the option for synchronization is not used, the synchronization input has to be connected to ground (0 V) or the sensor must be operated via a V1 cordset (4-pin). The synchronization function cannot be activated during programming mode and vice versa."

Is ground (O V) same with -Ub (negative terminal of the power supply)? I'm kind of confused why they use different terminology.

  • \$\begingroup\$ Friend, need make synchronize if you use more than one sensor. And your question : Ground is -V of source voltage,(ground not Earth !) \$\endgroup\$ – dsgdfg Apr 14 '16 at 12:20
  • \$\begingroup\$ For such a device & question you should be able to talk to the FSE (Field Service Engineer) from that company. I see the phone numbers on the bottom of the data sheet. \$\endgroup\$ – st2000 Apr 14 '16 at 13:19
