Position Signaling Switch Communication (Pss - Com); Ready-To-Close Signaling Switch For Communication (Com Rtc) - Siemens SENTRON 3WL10 Manual

Description
2.1 Communication modules
2.1.7

Position signaling switch communication (PSS - COM)

Via the communication link, the position signaling switch PSS - COM provides the signal
indicating whether the circuit breaker in the guide frame is inserted or removed.
Unlike the position signaling switch PSS, whose signals are available at the auxiliary
conductor terminal strip, the position signaling switch PSS - COM only signals two different
states:
● "INSERTED" breaker position (circuit breaker in the CONNECT position)
● "ISOLATED" breaker position (circuit breaker in the TEST or DISCONNECT position)
The PSS - COM position signaling switch is installed as standard if the withdrawable circuit
breaker is ordered for communication.

Ready-to-close signaling switch for communication (COM RTC)

The COM RTC module ascertains the ready-to-close state and transmits this information to
the communication system. The function is the same as that of the RTC ready-to-close
signaling switch.
The COM RTC module and the RTC ready-to-close signaling switch function can be
operated simultaneously.
The COM RTC module is installed as standard when the circuit breaker is ordered for
communication.
