Function description

Trip matrix logic

The trip matrix logic TMAGAPC function is used to route trip signals and other logical

output signals to different output contacts on the IED.

The trip matrix logic function has 3 output signals and these outputs can be connected to

physical tripping outputs according to the specific application needs for settable pulse or

steady output.

Setting guidelines

Operation: Operation of function Enabled/Disabled.

PulseTime: Defines the pulse time when in Pulsed mode. When used for direct tripping of

circuit breaker(s) the pulse time delay shall be set to approximately 0.150 seconds in order

to obtain satisfactory minimum duration of the trip pulse to the circuit breaker trip coils.

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.
