3.7.3
Impulse Signal for the Flag Indicator
A 󰊠ag indicator can be connected to terminals FI+/FI− (WIC1‑4: Out+/Out−) of the terminal
block X4, e. g. for a power-safe signaling of a trip.
The energy is provided by a capacitor store integrated in the WIC1 protection relay. The
length of the trip impulse is approx. 50 ms, the pause between the individual pulses depends
on the impedance of the 󰊠ag indicator and the current level. Pulsing is continued until the
assigned signal drops o󰊞.
Technical Data for the Setting Pulse
• Energy: E ≈ 0.01 Ws•
• Voltage: V ≈ 24 VDC•
CAUTION!
It is not allowed to connect any continuous / active voltage to the setting contact or to
the reset contact of the 󰊠ag indicator!
Any continuous voltage can destroy the coil that is built into the 󰊠ag indicator.
For a WIC1‑4, in particular, it is not permissible to connect a 󰊠ag indicator and set the
operating mode of the output to “output relay” (see ╚═▷ “Relay Output (WIC1‑4)”).
