Logic
OnDelay: Used to prevent output signals to be given for spurious inputs. Normally set to 0 or a low
value.
OffDelay: Defines a delay of the reset of the outputs after the activation conditions no longer are
fulfilled. It is only used in Steady mode. When used for direct tripping of circuit breaker(s) the off
delay time shall be set to at least 0.150 seconds in order to obtain a satisfactory minimum duration of
the trip pulse to the circuit breaker trip coils.
ModeOutputx: Defines if output signal OUTPUTx (where x=1-3) is Steady or Pulsed.
