Page 2: Warranty
I N T R O D U C T I O N — Scope and liability The functions, technical data, instructions for setting and commissioning of SME70-O devices are explained. This manual has been checked out, however, deviations from the description cannot be completely ruled out, so that no liability in a legal sense for correctness and completeness of the information or from any damage that might result from its use is formally disclaimed. -
Page 3: General Info
The correct detection of the fault direction also occurs in the presence of intermittent faults. SME70-O devices check the voltage of the three phases of the MT line and indicates whether it is ON or OFF; a current converter is also available with an impressed current output of 4...20 mA for sending the phase current measurement to the remote control terminal. -
Page 4: Main Features
The residual voltage is computed through vector sum of phase voltages. Sensors connections The sensors must be connected to the MA RJ45 connectors located inside the SME70-O panel. Remote control unit Remote control unit connections are implemented according with ENEL specification; they are abut- ted to the terminal board MB at the factory according to the connection diagram inside the device cover. - Page 5 5 of the MB terminal board. Endesa Functionality SME70-O permits, setting in \Set\Base\Mode the endesa mode. to enable Endesa functionality. In this mode: • The command of the 51 relay is issued only when, after tripping of thresholds 51,51N or 67NS2, the condition of “Voltage Absent”...
