(51/51N),
• 1 red LED indicating the earth fault function trip downstream of the device (67),
• 1 red LED indicating the device fail status,
• 1 green LED indicating auxiliary power (fix ON).
The fault indicator LEDs light up when a fault occurs (circuit breaker open), and they remain lit
(latched) until the phase voltages return (circuit breaker closed); latch may be extended for a pro-
grammable time (0 ... 238 hours) counted from the closing of the circuit breaker. The Trip Led Reset
Delay may be adjusted inside the
Set \ Base
menu.
The V4, V8, V12 LEDs, light up if the voltage of the relative phase is greater than 0.8 Vn and go OFF
when the voltage is less than 0.2 Vn; in
Voltage monitoring
mode voltage presence is indicated by a
flashing / LED relative to the corresponding phase.
