Network and system protection (NS protection) LINETRAXX® VMD460 Operating elements 2 - “ ON” LED (green): lights when the voltage supply is available and the device is in operation or flashes in case of a system error message (external watchdog). 1- B oth alarm LEDs “AL1” and “AL2”: light up in case of a limit value violation of voltage and frequency. 3 - Backlit LC display 4 - “INFO” button 5- U se the “TEST” button to run a manual self test which triggers both alarm relays (trigger test to check the coupling switches). In addition, fault simulation will be carried out with documentation of...

Network and system protection (NS protection) LINETRAXX® VMD460 Wiring diagram VMD460 (VDE-AR-N 4110:2018-11 – basic program 4110) Within the scope of VDE-AR-N 4110:2018-11, the VMD460-NA can be used as protective disconnection device for the generating unit or as higher-level protective disconnection, the latter, however, only if the Q-U protection function may be dispensed with. According to VDE-AR-N 4110:2018-11 chapter 10.3.3.4 par. 5, this is possible after consultation with the network operator and under the following conditions: • Generating plants with limited dynamic network support...
