ABB REQ650 - Configurable Logic Blocks

OnDelay: Used to prevent output signals to be given for spurious inputs. Normally set
to 0 or a low value. Used only for ModeOutputx: Steady.
OffDelay: Defines a minimum on time for the outputs. When used for direct tripping
of circuit breaker(s) the off delay time shall be set to approximately 0.150 seconds in
order to obtain a satisfactory minimum duration of the trip pulse to the circuit breaker
trip coils. Used only for ModeOutputx: Steady.
ModeOutputx: Defines if output signal OUTPUTx (where x=1-3) is Steady or Pulsed.
A steady signal follows the status of the input signals, with respect to OnDelay and
OffDelay. A pulsed signal will give a pulse once, when the Outputx rises from 0 to
1.
