2.3. External connections Connecting the CORES (without medium voltage) The current probes used with the LYNX 3400 are splitted core current sensors with a lever clasp on a resin-coated core. Ratio 1/500. The assembly uses three identical cores detecting: - single-phase faults on the earth... - Page 12 The wires for each core are connected using a coded 2-contact MATE-N- LOCK connector. A 4x1.5mm² U1000RO2V type cable equipped with female MATE-N- LOCK connectors is supplied for connecting cores to the LYNX 3400's J2 terminal block. Insert the stripped end with end sleeves into the LYNX's cable grommet.
- Page 13 - Pass the cable end through the appropriate cable gland (refer to page 7) - Connect to terminal strip J1 by doubling the wires in the terminal strip Important!!! In all cases you must restart the calibration procedure for all detectors (refer to page 19) LYNX 3400 72789_b NX2009363 manual...
- Page 14 Connecting the external indicator light housing The LYNX 3400's indicator light housing has red and green lights. It is supplied with a 3X1.5mm² U1000RO2V type cable. Position the indicator light with the cable gland facing downwards. Connect the J9 terminal block as follows:...
- Page 15 The LYNX 3400's normal power source is low voltage 230 V, which is available on site. The LV is supplied to the LYNX 3400 by a 2 x 1.5mm² U1000RO2V type cable – not supplied. LYNX 3400s does not need to be connected to the neutral earth.

Configuring the fault signaling delay A fault appearing on the network is signaled by the LYNX 3400 only if it causes the disappearance of the MV voltage after a configurable time notably allowing to avoid the activation of the signaling during the reclosing cycle. - Page 20 Launch of a LYNX 3400 Test To check the operation of the detector a press on the BP "Test" (BP4) starts the test procedure. If the LYNX 3400 is equipped with a display, it indicates "TEST". Both TS contacts close and the Red and Green LEDs flash on the Lynx board and the external LED for 1minute.

Function by function description The LYNX 3400 Detector is a fault detector for underground MV network of 15kV or 20kV voltage based on the Directional principle ie a simultaneous monitoring of residual current and voltage. It is in the form of a mono-card mounted in a housing designed to work inside a station The current signals are derived from 3 Tore type ITI sensors with a ratio of 500/1.

Page 27: Preventive
5.1. Preventive Deactivating the LYNX 3400 - Open the cover by unclipping it. - Disconnect the integrated power supply: Either the battery via J10,or the supercapacitor via J11 - If it has not been switched off externally before opening the cover, switch off the 230V power supply by opening the fuse holder. -
Page 28: Corrective
The 15-year usable life of supercapacitors means that they do not need to be replaced. 5.2. Corrective Should the equipment stop working, return the electronic board to Ensto Novexia. To do this, you need to: * Deactivate the case (see Page 27) -
