12.2.1 Ext1
Activation of this input causes immediate trip of the protection. The trip conditions are active throughout the
activation of this input.
12.2.2 Ext2
Activation of this input causes immediate trip of the protection. The trip conditions are active throughout the
activation of this input.
12.2.3 Fault Reset
Activation of this switch causes fault reset. The input has the same effect as pushing the button FltRes. If
permanently activated, every 100ms an impulse to fault reset the unit is done internally.
12.2.4 Alt Settings
Activation of this switch causes immediate switching to the alternative setting as per the setpoint groups
marked as „A.xx". In case that the switchover comes in the moment when a delay of some of the protection
stage is being count-down (the unit is about to trip), the timer setting is kept as before the switch. However, if
the trip conditions change during the delay run (e.g. by changing the protection threshold), the trip is not
performed.
12.2.5 Disable
Activation of this switch disables immediately all protective features of the unit. The switch may be used e.g.
in case that the generator is not yet in parallel-to-mains operation, and so the mains parameters do not have
to be evaluated. In this case, the unit does not trip on any fault condition.
12.2.6 CB Feedback
Deactivation of this switch confirms opening of the circuit breaker after a trip is issued by MainsPro G99TT. If
the feedback does not confirm opening of the CB, an additional back-up trip BakTrpPer or BakTrpImp will be
issued after adjustable time delay BakTrp Del.
