PulseTime

OnDelay
and
OffDelay
the behavior of each output can be customized. The
OnDelay
is always active and will
delay the input to output transition by the set time. The
ModeOutput
for respective output
decides whether the output shall be steady with an drop-off delay as set by
OffDelay
or if it shall
give a pulse with duration set by
PulseTime
. Note that for pulsed operation and that the inputs are
connected in an OR-function, a new pulse will only be given on the output if all related inputs are
reset and then one is activated again. For steady operation the
OffDelay
will pickup when all
related inputs have reset. Detailed logical diagram is shown in figure

Figure 489: Trip matrix internal logic
Output signals from TMAGAPC are typically connected to other logic blocks or directly to output
contacts in the IED. When used for direct tripping of the circuit breaker(s) the pulse time shall be
set to at least 0.150 seconds in order to obtain satisfactory minimum duration of the trip pulse to
the circuit breaker trip coils.
