Remote Flag Output
The remote flag output is used to indicate the trip via an external flag. The remote flag output provides 24 V,
0.01 Ws pulses of 50 ms on and 500 ms off.
The remote flag output operates when any protection function trips. The energy is stored in a capacitor built
into the protection relays. The capacitor is charged with an auxiliary voltage or phase current. The pulses are
repeated until the fault current falls below the set value. The remote flag output does not require any
mapping with protection functions.
NOTE

The time between the 2 pulses depends on the impedance of the flag indicator and on the current level (if
the relay is powered with an auxiliary power/phase current).
