5.6.4 Impulse output for the flag indicator
The energy-low tripping coil of the flag indicator is connected to terminals FI+ and FI-- of the second terminal block.
The energy is provided by a capacitor store integrated in the protection relay. Length of the trip impulse is 50ms;
the pause between the individual pulses depends on the impedance of the flag indicator and the current level. Puls-
ing is continued until the activation threshold is undershot.
Technical Data:
Energy:
E
≥ 0.01 Ws
Voltage:
≥ 24 V DC
It is not allowed to connect any active voltage to the trip coil output.
5.6.5 Measuring inputs for the CTs
The measuring inputs of the WIC1 protection system are matching the allocated CTs. Also the power requirement
of the relay and the CT output power match.
The connection of common CTs with secondary currents of 1 A or 5 A is inadmissible!
