  • Page 32 4.1.4 Siemens Connect Control If a local operator is using the Siemens Connect PC application to operate the line Fusesavers (this is called being in-session) then the RCU will not send controls to the Fusesavers and will not retrieve events from the Fusesavers. This is because Siemens Connect is considered to be a local operator and takes charge of communications to the Fusesavers.

    Like the Fusesaver, the CMR has multiple sources of control for Trips & Closes and for changing protection operation. 4.2.1 RCU as a conduit for data The RCU is simply a conduit from SCADA (and the Operator Panel) to the CMR. Therefore, as long as its local state allows it (see below), the RCU will o pass all requests (from SCADA or the operator panel) onto the target CMR without considering the CMR’s state or configuration.
  • Page 36 Trip and close operations can be triggered:  Automatically by the CMR as part of a protection sequence.  Using the yellow handle. o Optically Ganged installations: Pulling any yellow handle down will trip all phases. Putting the last yellow handle back up will close all phases. No close operations (from any source) will occur while any yellow handle is down.
