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

If the relay is powered via phase currents, then time between 2 pulses depends on the impedance of the
trip coil and magnitude of the current.
The remote flag output (along with pulse output and local flag) can be tested via device HMI. The option is
available under MAINTENANCE MENU ▶ Trip Pulse Test.
