12.3.6 !CommSigImp
Inverse immediate impulse signaling relay; opens immediately at any failure. The relay closes after
[s] (page 55)
since its opening. Any other detected fault-state during run of this timer has no effect. Fault
reset has no influence on this output.

12.3.7 CommSigDel
Impulse signaling relay delayed; closes at any failure with a delay given by appropriate parameter. The relay
closes immediately in case of LOM protection (Vector shift or ROCOF), External trip, incorrect phase rotation
or wrong phase polarity. Relay opens after
state during run of this timer causes a new activation of this relay or extends timing of
by the new impulse length from the moment of the failure detection. Fault reset has no influence on this
output.

The relay opens immediately in case of LOM protection (Vector shift or ROCOF), External trip, incorrect

12.3.9 U Sig
Immediate signaling relay – voltage; closes immediately in case of voltage failure (over, under voltage or
average overvoltage). The relay opens in case that all parameters are back within limits, but no sooner than
after Basic: Imp Len from its activation. If the relay is closed during trip activation, it opens no sooner than
Len [s] (page 55)
since trip status activation. Fault reset has no influence on this output. If any voltage
protection is disabled by setpoint (limit set to 0), the output does not signal activation of this protection stage.
