Remote control and remote annunciationThe standard Sepam 2000 control logic includescommunication tables. In the specific documents foreach application (motors, transformers,...), these tablespresent the assignment of remote control and remoteannunciation relaycoils.This function data file gives some information on theuse of the tables.Remote annunciationc Control fault: KTS1KTS1 = 1 if trip circuit fault (coil burnt out or wire cut)or position discrepancy fault occurs.c Remote control open / close fault: KTS2KTS2 = 1 if an open or close remote control order is not executed (discrepancybetween the remote control order and device position report).Use of this remote annunciation requires time delays T5 and T6to be set to 200 ms (with pocket terminal, timer heading in the program menu)or for communication).c Position / remote control discrepancy: KTS3KTS3 = 1 if the device's open / closed position does not match the last remotecontrol order that was transmitted. In such cases, the device was actuated bycommand that was not transmitted by the communication link (local command,protection tripping, process command...). Use of this remote annunciation requirestime delays T5 and T6 to be set to 200 ms (rubrique pocket terminal, timer headingin the control logic menu) or for communication).c External protection tripping: KTS4KTS4 = 1 if the Sepam has received a tripping order on input I15. This order isstored in the Sepam (lockout) and the user must acknowledge in order to unlockclosing. Input I15 is used to connect the output of a protection relay external to theSepam or to connect an intertripping order.c Sepam not reset: KTS5KTS5 = 1 until the Sepam 2000 is reset (acknowledgement) after fault tripping orinhibition of closing.c Device closed: KTS10KTS10 = 1 if the breaking device is closed (input I1 at 1).c Device drawn out: KTS11KTS11 = 1 if the breaking device is drawn out (input I17 at 1).c Breaking pole fault: KTS12KTS12 = 1 if there is a "pressure" fault in the breaking device (input I16 at 1).c Earthing switch closed: KTS13KTS13 = 1 if input I11 is at 1.c Remote control enable: KTS14KTS14 = 1 if input I18 remote control enable is at 1. This enabling relates to theremote control closing order (KTC34) and acknowledgement order (KTC35). Theremote control opening order (KTC33) takes priority, it does not depend on input I18.c KTS15 to 31: assigned to protection functionsEach Sepam 2000 protection function output is assigned a remote annunciation(latching outputs).c Transmit "blocking input": KTS32KTS32 = 1 if the Sepam 2000 send a blocking input (output O14 activated).c Disturbance recording inhibition: KTS51.c Remote setting inhibition: KTS51.Remote control ordersc "Open": KTC33Use of KTC33 may require time delay T5 to be set to 200 ms (see open / closecontrol function data sheet). KTC33 does not depend on the status of I18 remotecontrol enable.c "Close": KTC34Use of KTC34 may require time delay T6 to be set to 200 ms (see open / closecontrol function data sheet).KTC34 is processed if input I18 remote control enable is at 1.c Acknowledgement (reset): KTC35KTC35 plays the same role as the Reset key on the front of the Sepam 2000,KTC35 is processed if input I18 remote control enable is at 1.c Peak demand phase current zero reset: KTC36 (equivalent to the Clear key).c Peak demand W and VAr zero reset: KTC37 (equivalent to the Clear key).c Tripping current zero reset: KTC38 (equivalent to the Clear key).c Emmergency stop: KTC1v KTC1 = 1 activate breaker tripping control, group stop and desexcitation,v need to be reseted to 0 by the communication,v reseted to 0 in case of DC failure.c Group stop: KTC2v KTC2 = 1 activate breaker tripping control, group stop and desexcitation,v need to be reseted to 0 by the communication,v reseted to 0 in case of DC failure.2/2 Control and monitoring functions
