Network and system protection (NS protection) LINETRAXX® VMD460-NA

 Both alarm LEDs “AL1” and “AL2”: light when voltage and fre-
quency values are outside the thresholds.

 LED “ON” (green): lights up when voltage is available and 
when the device is in operation or flashes in case of system 
fault alarm (external watchdog).

Backlit LC display

“INFO” button 

 The test button “TEST” is used to start a manual self test that 
triggers both alarm relays (trigger test to check the coupling 
switches). In addition, a fault is simulated to determine the 
disconnection time.

    Arrow up button: parameter change, scroll

“RESET” button: to acknowledge alarm and fault messages

    Arrow down button: parameter change, scroll

 “MENU” button: to toggle between the standard display, 
menu and alarm display
