FAULT INDICATOR General description The earth-fault and short-circuit indicator can be used in radial networks with one input and ring networks. For earth-fault de- tection, the network has to be solidly earthed or low resistance- The potential-free connections between the short-circuit sensors, the earth-fault sensor and the display unit are done by fibre opti- cal cables. The short-circuit sensor can be mounted on screened and unscreened cables. The earth-fault sensor must be mounted All sensors are divisible and can be retrofitted on the cable. The fault indicators of the NG-Series have a compact design with low installation depth. The earth-fault and short-circuit indicator type EKL8001NG is equipped with two remote contact relays to indicate earth-faults Permanent earth-faults: Indication of permanent earth-faults by double blinking of the earth- 2nd short-circuit pass-through: Indication of a second short-circuit passing through by double blin- king of the respective short-circuit LED. Optional reset input: For reset by recovering 230 V AC External connectors Optical terminal (triple): Optical terminal (single): Connectors to short-circuit sensors L1, L2, L3 Connector to earth-fault sensor Remote reset input External blinking lamp (Type BL3.1 and BL4.1) Reset input for recovering 230 V AC (not for supply) SCADA remote contact (NC) SCADA remote contact (NO) SCADA remote contact for earth-fault indication (NO) SCADA remote contact for short-circuit indication (NO) Reset Input Reset Input Blinking white - ^~|| I IEFI licl I NO- ELEKTRO-MECHANIK EM GMBH Document Rev. 3 Ringstr. 4 - D-42553 Velbert / Germany Page 1
