Digital input Continuous
• Required for short circuit detection, when the breaker is tripped
independently due to a short circuit. One input is required for each
breaker.
• The breaker activates this input when it detects a short circuit. The
controller then activates the [Breaker] short circuit alarm.
5.5.9 Phase sequence error
This alarm is for phase sequence error protection.
The controller continuously checks the line voltage vectors on either side of the breaker against
the orientation defined in the controller. If the voltage is more than the detection voltage, and
the phase angle differs from the expected angle by more than ±40º, the alarm is activated. This
means that the alarm will also detect if the phase rotation is different from the direction of
rotation defined in the controller.
There are two alarms for each controller. These alarms correspond to the controller's AC
measurements. There is one alarm for the voltage from the [Source] (terminal B), and another
alarm for the voltage on the [Busbar] (terminal A).
